Dialogue in Our Cosmic Aloneness

The search for extraterrestrial intelligence (SETI) is briefly summarized to serve as a background for making the case that, due to the highly exceptional characteristics of the earth's position and motion in the solar system as well as the precarious history of human evolution, we may be alone in the universe. With the conviction that this cosmic isolation enhances our need for dialogue with God, I discuss the nature of authentic dialogue as exhaustively explored by Martin Buber. I conclude with remarks dealing with the importance of understanding and using Buber's insights on dialogue as a way of satisfying our primal need to communicate with a cosmic “other,” in particular, God. Thus, in contrast to the numerous articles that have discussed the theological implications of SETI being successful, I treat here what it might mean if we are alone.     

The diaconate as ecumenical opportunity: historical ecclesiological layers in understanding the diaconate

This article gives an account of the background to the Hanover Report, The Diaconate as Ecumenical Opportunity (1996), and in particular to the West Wickham consultation (1995). Recognising that the diaconate offers new ecumenical perspectives on ordained ministry, the author presents and critiques the Hanover Report for its harmonisation of contradictory positions, especially among Lutherans. The idea of diaconal ministries in the report makes the distinctive diaconate indistinct and gives rise to a mainly functional understanding of ministry. Ecclesiologically historical layers contradicting each other are mixed in such a way that the ecumenically productive eucharistic ecclesiology derived from the Early Church and central to the report's understanding of the diaconate remains at the end rather indistinguishable among the variety of other perspectives conveyed.     

The diaconate after the signing of the Porvoo Declaration: an overview of methods and hermeneutics

This article examines development in the deacon's ministry in the Porvoo Communion. Some of the initiatives which have contributed in significant ways to the common understanding of diaconal ministry in its member churches, since the signing of the Porvoo Declaration in 1996, are presented and analysed. The main focus is on methods used and on the way material has been interpreted by the churches or their representatives. The article also considers developments on two levels: first, on methods applied specifically by the individual Porvoo member churches, when presenting and interpreting the ministry of deacons; secondly, on the presupposed understanding behind the interpretations of deacons’ ministry in the Porvoo churches as a whole. The author's interest also encompasses the way in which the churches interpret significant differences and variety in the ministry of deacons within the Porvoo Communion, and what they regard as characteristic in current developments.     

The military chaplain: a study in ambiguity

This article looks at the ambiguities in the role of the military chaplain from three points of view. The first considers the nature of the constituency within which the chaplain ministers, paying particular attention to the degree – or otherwise – of secularisation and the reasons for this. The second examines the role of the chaplain in relation to the two institutions which he or she serves (i.e. church and state) and the tensions that emerge as a result. These are articulated in terms of ‘an angle of eschatological tension’. The third is concerned with ‘the roles within the role’ – that is the variety of tasks that make up the role of chaplaincy and the degree to which these are compatible with each other. The significance of theology in the resolution of the ensuing issues is set against diminishing societal resources in terms of religious literacy.     

On the Ethics of Facial Transplantation Research

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase.     

Together or Apart

Psychotherapists often mistake their theories for realities that they are not and thus may operate with an overly confident sense of "knowing" what is true about a particular couple relationship. Many schools of therapy tend to "pathologize" the dynamics of couple interaction and practitioners need to guard against being too inducted into any one world view. Facility with the theories and techniques of many different couples counseling strategies (psychodynamic, behavioral, structural and strategic approaches) can increase flexibility and the "working base" of therapists. Ultimately, however, the personhood of therapists, their awareness of their own biases (about levels of connection, emotional expressivity, feminism, or power relationships) and their ability to adopt a neutral, therapeutic stance are the essential ingredients for meaningful and curative couples counseling.     

社会决策中的公平准则及其神经机制

社会决策中的公平准则一直受到广泛的关注,经济学家和心理学家们分别从动机和认知的角度对这个课题进行了深入探索.在这些工作中,最为突出的是“均等”,“互惠”和“情绪”三个模型的提出.均等和互惠模型试图从动机角度理解个体的公平行为,而情绪模型则更强调个体在公平决策中的认知和情绪的加工过程.近年来脑成像的研究也为这些模型提供了相应的支持,其中与公平准则最密切的脑区是脑岛和背外侧前额叶:前者一般被认为是反映了个体面对不公平待遇时的负性情绪体验;而后者主要负责决策过程中的抑制控制.但这些脑区具体的功能还存在很多争议,反映了不同理论模型对特定脑区功能的不同理解.未来研究应注意三个模型之间的相互补充,以及加强多模态的脑指标的运用,并注重相关脑区的整体性,此外,公平决策行为中的个体差异,以及社会情境对其的影响也应受到重视.     

探索性结构方程建模(ESEM):EFA和CFA的整合

探索性结构方程建模(ESEM)是在测量模型部分使用了类似于EFA模型的SEM.作为一种高级统计方法,ESEM整合了EFA和CFA两种因子分析方法的功能和优点.通过ESEM,研究者既可以灵活地探索因子结构,又可以系统地验证因子模型,为潜变量的关系分析提供更适宜的测量模型.ESEM已经在某些社科领域的研究中得到应用,是一种值得推介的因子分析方法.ESEM的具体应用问题,例如因子旋转方法的选用、测验信度评价等,仍有待探讨.     

猜谜作业中的ERP效应：基于催化范式的证据

运用ERP技术对个体猜谜任务下的顿悟和无顿悟的情况进行探索。结果发现,在300ms-500ms内,有顿悟比无顿悟引发了更负的N300-500成分,激活了大部分脑区;在600ms-1100ms内,有顿悟比无顿悟引发了更正的P600-1100成分,在中央区显示了最强激活。结果表明,N300-500可能反映了定势破除中的认知冲突,P600-1100可能反映了新异联系的形成。     

汉字识别的时间进程：来自字谜任务的ERP证据

通过“学习-测试-判断”的三阶段实验范型, 采用事件相关电位（ERP）技术探讨了猜谜任务中对谜底答案（单个汉字）识别的脑内时程动态变化。结果发现：语义识别与字形识别下,汉字刺激均诱发了明显的N1、P2和N2成分,其中语义识别下的P2波幅表现为更加正性,可能与汉字语义的早期加工有关;随后,300-400ms内,语义识别比字形识别诱发了一个更加正性的ERP成分,该成分可能属于P300成分,反映了对汉字语义的进一步整合加工;最后,500-600ms内,语义识别比字形识别同样诱发了一个更加正性的ERP成分,可能反
