Abstract. This paper introduces the thought of Pierre Teilhard de Chardin from a perspective neglected until now: a view that builds on the analysis of his scientific papers. His scientific work formed part of the "modern synthesis" which laid the foundation of contemporary Darwinism. His main contributions in the field were the definition of a new branch of evolutionary sciences, geobiology; the redefinition of the term orthogenesis ; and the proposal of the "scale" phyletic tree. Using these new research concepts, Teilhard de Chardin attempted to solve, within a scientific framework, a problem fundamental for his philosophical synthesis: that of evolutionary directionality.  相似文献

该实验利用免疫组化技术,在已有实验的基础上进一步观察比较了左眼视剥夺及单眼学习后,Jun样蛋白在雏鸡两侧半球HV和LPO中表达的差异。实验结果表明:1.视剥夺2、24、48、72小时后观测到Jun样蛋白在左、右半球HV和LPO中的表达逐渐增高,并且于视剥夺48小时表达到达峰值。同时仅在视剥夺2小时后观测到两半球LPO中Jun样蛋白的表达存在差异,在其余各视剥夺时程中两侧半球的LPO、HV中Jun样蛋白的表达均无显著差异。2.视剥夺2小时和24小时后均在学习后70分钟组中观测到Jun样蛋白在左、右半球的HV和LPO中表达的显著升高,而在视剥夺2小时学习后10分钟只观测到左半球HV和LPO中Jun样蛋白表达的显著升高,在视剥夺24小时学习后10分钟中仅观测到左半球LPO中Jun样蛋白的显著升高。同时也仅在视剥夺2小时学习后10分钟观测到两侧半球HV、LPO中Jun样蛋白表达的显著性差异。3.无论单纯视剥夺组还是单眼学习组,各组同侧半球中LPOJun样蛋白的表达显著高于HV的Jun样蛋白的表达现象在视剥夺48小时后消失。  相似文献

Recent evidence strongly suggests that the relationship between threshold elevation ( T ) and fraction of bleached rhodopsin ( B ), obtained during a major, middle period of long-term rod dark adaptation in man, is well described by a power function, i. e., T = k · Bn , where k is a multiplicative constant and n is the exponent. Due primarily to the low reliability of measurements of rhodopsin regeneration, however, the exponent n of the power function cannot, at present, be given an exact value. Available information indicates that the value of the exponent ranges between 2.4 and 4. Implications of this uncertainty are discussed within the framework of the allosteric, tetrameric model of rod dark adaptation. It is concluded that this model in its simplest form may only offer a first approximation of the real system implicated in the process.  相似文献

Despite the considerable potential of qualitative approaches for studying the systemic and constructionist therapy process due to shared theoretical and epistemological premises, to date there is lack of a comprehensive qualitative synthesis of how change process is experienced and conceptualized by clients and therapists. To address this evidence gap, we performed a systematic meta‐synthesis review of 30 studies reporting clients’ and therapists’ retrospective narratives of change process across systemic and constructionist models and across a range of client configurations, including individuals, couples, families, and groups. The studies were identified following a systematic search in PsycINFO and MEDLINE resulting in 2,977 articles, which were screened against eligibility criteria. Thematic analysis led to the identification of four main themes: (1) navigating through differences, (2) toward nonpathologizing construction of problems, (3) navigating through power imbalances, and (4) toward new and trusting ways of relating. Findings illustrate the multifaceted aspects of systemic and constructionist change process, the importance for their reflexive appraisal, and the need for further research contributing to the understanding of the challenges inherent in the systemic and constructionist therapeutic context.  相似文献

Agreement about theosis in Orthodox–Reformed dialogues played a small but strategic role in the ecumenical recovery of the patristic doctrine of deification and its emergence as a locus of Reformed theology. Ecumenical dialogue helped dispel the idea that theosis is a distinctively Orthodox doctrine incompatible with the Western tradition. This idea was first propounded in the 19th century by Albrecht Ritschl, Ferdinand Kattenbusch, Adolf von Harnack, and others associated with the Ritschlian school. It was later appropriated by émigré Orthodox scholars. Orthodox–Reformed dialogue helped correct this and other misconceptions about theosis. This began informally in correspondence between Thomas F. Torrance and Georges Florovsky and continued in formal dialogue meetings. Orthodox–Reformed dialogue also highlighted patristic ways of thinking about salvation that were not then prominent in Reformed theology. However, as the Reformed participants consulted the works of John Calvin, they realized that he shared those patristic ways of thinking. Today, Reformed theologians are eager contributors to the ecumenical recovery of theosis. They increasingly discuss theosis as a doctrine native to the Reformed tradition.  相似文献

There is a growing understanding that addressing the global crisis facing humanity will require new methods for knowing, understanding, and valuing the world. Narrow, disciplinary, and reductionist perceptions of reality are proving inadequate for addressing the complex, interconnected problems of the current age. The pervasive Cartesian worldview, which is based on the metaphor of the universe as a machine, promotes fragmentation in our thinking and our perception of the cosmos. This divisive, compartmentalized thinking fosters alienation and self‐focused behavior. I aim to show in this essay that healing the fragmentation that is at the root of the current world crises requires an integrated epistemology that embraces both the rational knowledge of scientific empiricism and the inner knowledge of spiritual experience. This “deep science” transcends the illusion of separateness to discern the unity, the unbroken wholeness, that underlies the diverse forms of the universe. Our perception of connectedness, of our integral place in the web of life, emerges as an attribute of our connection with the eternal, beatific source of all existence. This awakened spiritual vision “widens our circle of understanding and compassion, to embrace all living creatures in the whole of nature” (Einstein, quoted in Goldstein [1976] 1987). Our behavior, as it emerges naturally out of our perception of the sacredness of the natural world, will naturally embody love and respect for all life forms. This vision promotes the healing of our long‐standing alienation from the natural world and offers hope for renewal in the midst of widespread cultural deterioration and environmental destruction.  相似文献

The authors reviewed 12 studies using the Counselor Burnout Inventory, including the results from their original, large‐sample study of school counselors (N = 1,005). Aggregated internal consistency (coefficient alpha) was .90 (N = 1,708), and subscale alphas ranged from .73 to .86 (N = 2,809). Test–retest reliability was .81 (N = 18; k = 1), with subscale test–retest reliability estimates ranging from .72 to .85. Convergent comparisons were robust across 10 instruments. Structural validity indicated a 5‐factor solution and an adequate to good fit of the model to the current study's data.  相似文献
