On rotating to smooth functions

Tucker has outlined an application of principal components analysis to a set of learning curves, for the purpose of identifying meaningful dimensions of individual differences in learning tasks. Since the principal components are defined in terms of a statistical criterion (maximum variance accounted for) rather than a substantive one, it is typically desirable to rotate the components to a more interpretable orientation. Simple structure is not a particularly appealing consideration for such a rotation; it is more reasonable to believe that any meaningful factor should form a (locally) smooth curve when the component loadings are plotted against trial number. Accordingly, this paper develops a procedure for transforming an arbitrary set of component reference curves to a new set which are mutually orthogonal and, subject to orthogonality, are as smooth as possible in a well defined (least squares) sense. Potential applications to learning data, electrophysiological responses, and growth data are indicated.Portions of this research were supported by the National Research Council of Canada, Grant A8615 to the second author.

“Together towards a Banquet”: The Feast as Promise and Resistance in Together Towards Life and Contemporary Theological Discourse

This article explores the symbol of the feast, as proposed by the 2012 World Council of Churches’ affirmation Together towards Life: Mission and Evangelism in Changing Landscapes (TTL). The feast is introduced as an appropriate hermeneutic tool to account for the multi-layered and dynamic reality of human life in the presence of others and in the presence of God. Interpreting the feast, together with TTL, as a symbol of the liberation and reconciliation of the whole creation and of the celebration of life in response to the outreaching love of God, the article reflects on some contemporary theological voices arguing that God’s invitation to the feast of God’s kingdom is a central element of Christian existence. Such feasting is, among other things, characterized by the dynamics of facing, the presence of the other, the awareness of human corporeality, and the particularization of the other that can overcome the idolatrous power of death. Entering this conversation, the present article will argue that the symbol of the feast can helpfully be understood in its two-fold dynamics of promise and resistance. While giving assurance about the transformation of all reality in the coming reign of justice and peace, the symbol of the feast, with its emphasis on inclusiveness and equality, also empowers people to resist all life-denying forces. Walking with the rest of the creation “together towards a banquet,” Christians are thus enabled, it will be asserted, to discern and actively live their vocation.     

Making a Difference: The Social Ecology of Social Transformation

A multidisciplinary and multilevel framework for social transformation is proposed, encompassing four foundational goals: capacity-building, group empowerment, relational community-building, and culture-challenge. Intervention approaches related to each goal are presented at the setting, geographic community, and societal levels. Four exemplars of social transformation work are then discussed: the Accelerated Schools Project, Meyerhoff Program, ManKind Project, and women's movement. These examples illustrate the synergistic relationship among the four transformational goals, within and across levels of analysis, which is at the heart of the social transformation process. The paper concludes with three challenges to guide our efforts as we enter the new century: (1) to move social transformation to the center of our consciousness as a field; (2) to articulate jointly with allied disciplines, organizations, and citizen groups an encompassing, multidisciplinary, and multilevel framework for social transformation; and (3) to do the above with heart, soul, and humility.

临床医学整合：中心化整合关键在于观念转变

医学转型的实质是推进医学的整合,微观层面以临床医学的整合为核心部分,宏观上则以临床医学与预防医学的整合为核心。在诸多整合之中,以临床医学的整合最为迫切,它是整个医学整合过程中的基础和开端。当前进行的临床中心化整合似乎已成为一种主导的趋势,然而,如何进行中心化整合却仍然存在诸多问题需要探讨,某些医院对专科化的热衷和偏爱更令人担忧,医学资本的诱惑也是当今临床整合的一道障碍,因此,医学整合任重而道远,不仅需要医学形式上的重组,更需要有观念上的根本转变。     

Deep structure,cognition and rebirth: Propositions for viability and vitality in human systems

This paper describes systems dynamics related to deep structure and development processes in human systems, to the process of arresting entropy or premature death in these systems and to the relationship between the cognition of deep structure, its outward manifestation and human systems viability and vitality. The paper proposes that inherent forces are present in systems that act to bring about alignment between inner deep structure and a system's manifested outer structures and processes, thereby enhancing viability and vitality. Deep structure is seen as a force toward self‐organization and rebirth.     

THE NEUROSCIENCE OF WESLEYAN SOTERIOLOGY: THE DYNAMIC OF BOTH INSTANTANEOUS AND GRADUAL CHANGE

In his work Rewired: Exploring Religious Conversion, dealing with Wesleyan soteriology and neuroscience, Paul Markham claims that when one incorporates biology as an epistemic restriction in theologies of conversion, doctrines of instantaneous conversion are invalidated. He asserts that conversion must always be gradual, because the mechanism by which the brain changes in response to experience does not occur instantaneously; rather change is initiated and consolidated over an often lengthy span of time. I argue, however, that doctrines of instantaneous conversion are maintained when taking neuroscience into account. First, for doctrines of conversion that hold to the imputation of Christ's righteousness, neuroscience is irrelevant, because statements of instantaneous change are in terms of a relational status and not biological. Rapid conversion is maintained as a metaphysical position. Second, an embodied and neurologically realized change is expected in theologies of conversion that hold to impartation and, contrary to Markham, immediate change is neurologically possible in a variety of ways.     

Fundamentalism and the masculine body: The case of Jewish Ultra-Orthodox men in Israel

The predominant model in the literature on fundamentalism focuses on the tense relationship between contemporary radical religious movements and their environment. The characteristic violence that has made fundamentalism notorious is conventionally explained in terms of defensive or offensive reactions to the challenge of the modern secular society. In light of recent developments in the fundamentalist world, we propose to employ a novel analytic framework to update and revise the current conceptualization. Our argumentation is based on extensive fieldwork in a particular case of Jewish fundamentalism. We introduce into the agenda of fundamentalism research a category conspicuously absent thus far: the body. Results of ethnographic study of Ultra-Orthodoxy in Israel throw light on the very existence of fundamentalist body, and emphasize its implications for better understanding the fundamentalist predicament. The body poses a major problem to fundamentalists and plays a key role in their typical behavior and particularly in their violence. Discussing fundamentalism in terms of the body allows us to see its militancy as a solution to intra-fundamentalist problems that emerge in advanced stages of the movements' life, on the one hand, and paradoxically as a means towards reconciliation with the movements' environment normally regarded as its enemy, on the other hand. In the case presented here the fundamentalist violence is manifested in various hitherto unexplored ways including an enthusiastic service in the military of the nation-state. Such peculiar violence indicates present-day fundamentalist experimentation in an attempt to establish new possibilities of coming to terms with ever changing social and political reality, while at the same time to pursue revolutionary options of radical religious experience.
