Wolfhart Pannenberg 《Zygon》1989,24(2):255-271
Abstract. Philip Hefner's focus on contingency and field as the guiding concepts in my thinking and his characterization of my theological enterprise as a Lakatosian research program are appropriate and helpful.
I welcome Jeffrey Wicken's holistic approach to the emergence of life. Theology can appropriate the language of self-organizing systems exploiting the thermodynamic flow of energy degradation for interpreting organic life as a creation of the Spirit of God.
However, I cannot sympathize with Lindon Eaves's equation of "hard science" with a reductionism which raises the double helix to the status of icon; the "meaning" of DNA derives from its place in the total phenomenon of life—not the reverse.
Frank Tipler's cosmology raises the prospect of a rapprochement between physics and theology in the area of eschatology. A Christian cosmology, however, would require at least three modifications: contingency in the history of creation; the uniqueness of Jesus' resurrection; and the relation of these to the problem of evil.  相似文献

一种新的统计方法和研究思路——结构方程建模述评   总被引:11,自引:0,他引:11  
张建平 《心理学报》1993,26(1):94-102
结构方程建模(SEM)是一种新的统计方法和研究思路,近年来在心理学和社会科学领域的应用日益增多。本文在非数学化的基础上,结合心理学研究实例介绍了SEM的渊源、发展、基本概念、分析过程以及相应的计算机统计软件LI-SREL。本文认为SEM有四大优点:①引进潜变量使研究更为深入,②遵循一般线性模式进行验证型分析,使研究更有意义,③妥善处理多变量间的复杂关系,④模型具有参数不变性。SEM应该引起国内心理学界的重视。  相似文献

In recent years increased attention has been directed to prevention research as a means of solving the multitude of complex social and health problems which confront individuals and their societies. Abuse of substances, behavioral dysfunctions, violence, emotional disorders, educational failures, unwanted pregnancies and sexually transmitted diseases are but a few examples of these most difficult problems. As our recognition of the need for sound prevention strategies has grown, so has our sophistication in designing prevention research studies to evaluate the effectiveness of these new strategies. And that sophistication has brought new challenges, some of which are capable of stifling progress because of their complexity. This problem is certain to grow in importance as interventions with multiple components are used more frequently to meet the challenges of the complex social and health problems we face. This special issue evolved out of the recognition that prevention researchers are confronted by a myriad of difficult methodological issues which have inhibited progress in this area. The articles in the issue present innovative methodological solutions designed to overcome these problems so the field can move forward. Editor's Note: Dr. Edward Seidman edited Methodological Issues in Prevention Research while serving as Associate Editor for Methodology.  相似文献

The design, conduct, and analysis of prevention research efforts present formidable challenges, but as the papers in this volume illustrate, the problems of prevention research are probably not altogether intractable; they simply require the best of our thinking and the firmest of our commitments. The papers included in this issue represent some of the best thinking likely to be available, and, in aggregate, they give reason for some optimism about prevention research. Which is fortunate, because it is by now abundantly clear that treatment of all the assorted personal and social maladies that afflict us individually and as a society, is impossibly intrusive and expensive, even if we were certain we knew what to do, and we are not. Treatment research is only a step or two ahead of prevention research in nearly any field.  相似文献

Assessing the contributions of individual components in multi-component interventions poses complex challenges for prevention researchers. We review the strengths and weaknesses of designs and analyses that may be useful in answering three questions: (1) Is each of the individual components contributing to the outcome? (2) Is the program optimal? and (3), Through what processes are the components of the program achieving their effects? Factorial and fractional factorial designs in which a systematically selected portion of all possible treatment combinations is implemented are used to address question 1. Response surface designs in which each component is quantitatively scaled are explored in relation to question 2. Mediational analysis, a hybrid of experimental and correlational approaches, is considered in relation to question 3. Design enhancements are offered that may further strengthen some of these techniques. These techniques offer promise of enhancing both the basic science and applied science contributions of prevention research.  相似文献

This paper describes the collaborative endeavours of residents and a wide range of professional workers in a particular area of Nottingham, with reference to a community psychology approach to addressing sources of psychological distress. The activities include a survey of people's views about living in the area and the factors they identify as affecting their health; and initiatives in community participation and action. One hundred and twenty three people were interviewed by members of the Sneinton and Bakersfield Community Forum. Harmful influences upon health and causes of stress were revealed as litter, dog dirt, air and traffic pollution, feeling unsafe to go out at night and lifestyle-related issues such as smoking and diet. Public meetings, the local press and short written reports were used to publicize these results and encourage further involvement. Many local residents and professionals are now active in a network of groups which address social and environmental concerns.  相似文献

Empirical research pertaining to cardiopulmonary resuscitation (CPR), clinician behaviors related to do-not-resuscitate (DNR) orders and substituted judgment suggests potential contributions to medical ethics. Research quantifying the likelihood of surviving CPR points to the need for further philosophical analysis of the limitations of the patient autonomy in decision making, the nature and definition of medical futility, and the relationship between futility and professional standards. Research on DNR orders has identified barriers to the goal of patient involvement in these life and death discussions. The initial data on surrogate decision making also points to the need for a reexamination of the moral basis for substituted judgment, the moral authority of proxy decision making and the second-order status of the best interests standard. These examples of empirical research suggest that an interplay between empirical research, ethical analysis and policy development may represent a new form of interdisciplinary scholarship to improve clinical medicine.  相似文献

This paper is the third in a series of reports on preliminary empirical findings from replications of an integrated system of care for youth suffering from serious emotional disturbance. The development of the innovative system of care was pioneered in Ventura County, California, and the replications in three other California counties were legislatively enabled through California legislation (Assembly Bill 377). This report presents results on the expenditure and utilization of foster homes, residential placements made through special education programs, and state hospitals. Evaluation results indicate that foster home and state hospital utilization and expenditures are lower for the counties replicating the innovative system of care than for the state of California as a whole. Expenditures for special education residential placements are either at the state rate or lower in one county. The cumulative evidence supports the conclusion that the replication counties are utilizing restrictive levels of care at lower rates than would be expected, given state-wide patterns. The results, in conjunction with prior findings, are discussed in the context of questions about the possible fates of youth who no longer live in publicly funded residential facilities.  相似文献

单一因果关系因果力判断研究述评   总被引:2,自引:0,他引:2  
简单因果归纳包括自下而上的材料驱动的加工和自上而下的因果知识驱动加工两个方面。简单因果归纳的多数理论模型强调自下而上的材料驱动的加工,这些模型又存在联想解释与计算解释的基本区分。最后,概述了单一因果关系因果力判断研究的基本问题:因果力判断的主要影响因素和过程机制、研究的方法问题。  相似文献
