关键词： 资本主义意识形态   主流意识形态   认同   控制  

摘要： 资本主义意识形态虽然有其自身无法克服的内在矛盾,但自从战胜封建意识形态以来,先是被英美等发达资本主义国家普遍认同,而成为主流意识形态,后又扩大到欧洲,乃至世界各地。资本主义意识形态的认同与控制策略主要有:不断扬弃、调整、修正,使其适应资本主义的发展;利用传媒、宗教等加强对意识形态的宣传与控制;利用霸权向外输出,并采取各种手段打压异己,维护资本主义意识形态。探讨资本主义实现意识形态认同和控制的策略,可为我国社会主义主流意识形态建设提供借鉴。

关键词： 实验比较   实验条件的控制  

摘要： 所有的实验,都是在条件控制下进行的。体现控制实验条件思想的最常见的教学手段是实验比较法。人教版初中化学教材实验类型,多数实验属于比较法。因此在具体的教学过程中,我们教师需要做到：突出实验方法引导分析,注意凸显实验比较思想;适时改进增加比较探究,促进学生形成条件控制意识。

关键词： TUMORS -- Growth   CANCER cells   CELLULAR pathology   CARCINOGENESIS   STEM cells  

摘要： Identification of the cell types capable of initiating and sustaining growth of the neoplastic clone in vivo is a fundamental problem in cancer research. It is likely that tumor growth can be sustained both by rare cancer stem--like cells and selected aggressive clones and that the nature of the mutations, the cell of origin, and its environment will contribute to tumor propagation. Genomic instability, suggested as a driving force in tumorigenesis, may be induced by genetic and epigenetic changes. The feature of self-renewal in stem cells is shared with tumor cells, and deviant function of the stem cell regulatory networks may, in complex ways, contribute to malignant transformation and the establishment of a cancer stem cell--like phenotype. Understanding the nature of the more quiescent cancer stem--like cells and their niches has the potential to develop novel cancer therapeutic protocols including pharmacological targeting of self-renewal pathways. Drugs that target cancer-related inflammation may have the potential to reeducate a tumor-promoting microenvironment. Because most epigenetic modifications may be reversible, DNA methylation and histone deacetylase inhibitors can be used to induce reexpression of genes that have been silenced epigenetically. Design of therapies that eliminate cancer stem--like cells without eliminating normal stem cells will be important. Further insight into the mechanisms by which pluripotency transcription factors (e.g., OCT4, SOX2, and Nanog), polycomb repressive complexes and microRNA balance self-renewal and differentiation will be essential for our understanding of both embryonic differentiation and human carcinogenesis and for the development of new treatment strategies.

摘要： In the competition for limited processing resources, top-down attention and cognitive control processes are needed to separate relevant from irrelevant sensory information and to interact with the environment in a meaningful way. The demands for the recruitment of top-down control processes depend on the relative salience of the competing stimuli. In the present event-related functional magnetic resonance imaging (fMRI) study we investigated the dynamics of neuronal networks during varying degrees of top-down control demands. We tested 20 participants with a dichotic auditory discrimination task in which the relative perceptual salience of two simultaneously presented syllables was parametrically varied by manipulating the inter-aural intensity differences (IIDs) and instructing the subjects to selectively attend to either the louder or weaker of the two stimuli. A significant interaction of IID manipulation and attentional instruction was detected bilaterally in the inferior parietal lobe and pre-supplementary motor area, and in the precentral gyrus, anterior cingulate cortex, and inferior frontal gyrus of the right hemisphere. The post hoc analysis of the interaction pattern allowed for an assignment of these regions to either of two sets of regions which can be interpreted to constitute two different brain networks: a frontoparietal attention control network, involved in the integration of saliency-based and instruction-based processing preferences, and a medial-lateral frontal cognitive control network, involved in the processing of the conflicts arising in the attempt to follow the attentional instruction in face of the varying inter-aural stimulus salience.

摘要： 后工业社会作为资本主义发展新的阶段,出现了一些不同于以往的变化。这些变化带来了资本主义社会意识形态实践的改变,同时也给我国的意识形态建设提出了挑战。针对挑战,我们从加强马克思主义意识形态的主体地位、对传播媒介的引导和理论队伍建设三个方面探讨我国的意识形态的建设问题。

摘要： 执行功能（executive function，EF）是当前心理学研究中应用广泛但定义较为混乱的一个概念，一般指涉及对思想和动作进行意识控制的心理过程。最初的研究源于从神经心理学的角度对前额皮质（prefront Mcodex，PFC）损伤的患者所出现的一些神经心理缺陷进行的研究。
