Inferring latent class lexicographic rules from choice data

A lexicographic rule orders multi-attribute alternatives in the same way as a dictionary orders words. Although no utility function can represent lexicographic preference over continuous, real-valued attributes, a constrained linear model suffices for representing such preferences over discrete attributes. We present an algorithm for inferring lexicographic structures from choice data. The primary difficulty in using such data is that it is seldom possible to obtain sufficient information to estimate individual-level preference functions. Instead, one needs to pool the data across latent clusters of individuals. We propose a method that identifies latent clusters of subjects, and estimates a lexicographic rule for each cluster. We describe an application of the method using data collected by a manufacturer of television sets. We compare the predictions of the model with those obtained from a finite-mixture, multinomial-logit model.     

LÉVY HIERARCHY IN WEAK SET THEORIES

We investigate the interactions of formula complexity in weak set theories with the axioms available there. In particular, we show that swapping bounded and unbounded quantification preserves formula complexity in presence of the axiom of foundation weakened to an arbitrary set base, while it does not if the axiom of foundation is further weakened to a proper class base. More attention is being paid to the necessary axioms employed in the positive results, than to the combinatorial strength of the positive results themselves.     

Prayer as Therapeutic Process Toward Aliveness Within a Spiritual Direction Relationship

This article underscores the potential benefit of a specific form of Christian prayer that creates space within a spiritual direction relationship for the creation of inner images that reveal a person’s unconscious relational longings and co-created representations of God. In this specific type of prayer that can be facilitated by mental health professionals and pastoral counselors, imagery of God’s presence is created in the space between a Christian spiritual director and a Christian directee while they are open to inner experiences that reveal God’s presence interacting with infantile processes toward aliveness. Aliveness is understood using Winnicottian notions in dialog with theories proposed by Allan N. Schore, affective neuropsychologist and Clinical Faculty at UCLA David Geffen School of Medicine, Ann Belford Ulanov, Jungian Analyst and Professor of Psychiatry and Religion at Union Theological Seminary and W.R.D., British psychoanalyst in the Objects Relations School. Ideas of transitional space, good enough mother, holding environment, aggression, creativity, and play are set alongside theories of affect regulation, the developing brain, co-created objective God images, the relational nature of God and being received as good while illuminating three prayer experiences during one 30-year-old Asian American woman’s 16-month therapeutic process toward aliveness.

J. Robert Oppenheimer: A Faith Development Portrait

J. Robert Oppenheimer was among the most important and enigmatic figures in 20th century science. He is best known for successfully directing the Manhattan Project that produced the first atomic bombs that were dropped on Japan at the end of World War II. Subsequently, he became a scientist and statesman who advised the United States government in the areas of atomic weapons development and public policy. He later became subject to an investigation in 1954 into his previous political affiliations and his personal behavior that ended in the revoking of his security clearance. This essay seeks to chronicle Oppenheimer’s coming of age as a public intellectual with a view toward his own psychological history and most especially in relationship to the stages of faith development articulated by James Fowler and colleagues. Moreover, though not conventionally religious, Oppenheimer’s life and thought were permeated with themes and ideas of a religious and ethical nature that shaped his adult character and informed his view of the world. This essay was originally presented at The Richardson History of Psychiatry Research Seminar at Weill Cornell Medical College.     

The Metallic Womb

This study of malevolent narcissism examines the relationship between the Washington Snipers, Muhammad and Malvo, from the perspectives of attachment theory and Kleinian theory. Muhammad embodied a perverted understanding of manliness. Malvo was desperate for the love of a father, and fused with the omnipotent destructiveness of John Muhammad. Together they embarked on a failed Quest, recreating the original infant/caregiver scenario, which in their experience was about destruction and death, rather than gratitude and life. Malvo and Muhammad were perfect together, merged into one unit devoted to murder. Their victims were random and multiple, like their early caregivers.     

Speech Perception: Cognitive Foundations and Cortical Implementation

ABSTRACT— Speech perception includes, minimally, the set of computations that transform continuously varying acoustic signals into linguistic representations that can be used for subsequent processing. The auditory and motor subroutines of this complex perceptual process are executed in a network of brain areas organized in ventral and dorsal parallel pathways, performing sound-to-meaning and sound-to-motor mappings, respectively. Research on speech using neurobiological techniques argues against narrow motor or auditory theories. To account for the range of cognitive and neural attributes, integrative computational models seem promising.     

意见收敛定理与休谟问题

意见收敛定理是主观主义概率论的一条重要定理,它表明随着证据的增加,验前概率的主观性将被验后概率的客观性所代替。意见收敛定理被看作主观概率的动态合理性原则,因而被用来解决休谟问题,即归纳合理性问题。然而,哈金有说服力地表明,意见收敛定理证明的是条件概率Pr（h／e）的收敛,而不是验后概率Pre（h）的收敛。主观主义概率论暗中接受的一个等式是：Pre（h）=Pr（h／e）,通常称之为“条件化规则”。这样,归纳法的合理性问题变成条件化规则的合理性问题。为此,本文提出一个新的合理性原则,即“最少初始概率原则”,将它同“局部合理性”观念结合起来便可为条件化规则的合理性加以辩护。

Measuring model flexibility with parameter space partitioning: an introduction and application example

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data-fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general-purpose method for analyzing and comparing all classes of cognitive models. PSP is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.     

HIERARCHIES: THE CORE ARGUMENT FOR A NATURALISTIC CHRISTIAN FAITH

This article takes on a perhaps impossible task: not only to reconstruct the core argument of Arthur Peacocke's program in science and religion but also to evaluate it in two major areas where it would seem to be vulnerable, namely, more recent developments in systems biology and the philosophy of mind. If his theory of hierarchies is to be successful, it must stand up to developments in these two areas and then be able to apply the results in a productive way to Christian theological reflection. Peacocke recognized that one's model of the mind‐body relation is crucial for one's position on the God‐world relation and divine action. Of the three models that he constructed, it turns out that only the third can serve as a viable model for theology if it is to be more than purely deistic or metaphorical.
