Covenant,blood, and violence: America at war with itself and others

Religious nationalism is dangerous, because it tends toward violence. In the case of America, religious nationalism is preceded by, and dependent upon, a covenant with God that renders judgment against the nation when it fails to embody divine justice. The second use of the law in Lutheran theology, combined with René Girard's scapegoat theory, provides the prophetic public theologian with a searchlight to make visible the nation's justification of violence. The haunting question becomes this: should the prophetic public theologian expose the lie on which American religious nationalism is built and risk sundering human community?     

Acquaintance and the Problem of the Speckled Hen

This paper responds to Ernest Sosa’s recent criticism of Richard Fumerton’s acquaintance theory. Sosa argues that Fumerton’s account of non-inferential justification falls prey to the problem of the speckled hen. I argue that Sosa’s criticisms are both illuminating and interesting but that Fumerton’s theory can escape the problem of the speckled hen. More generally, the paper shows that an internalist account of non-inferential justification can survive the powerful objections of the Sellarsian dilemma and the problem of the speckled hen.     

Models of God

This essay compares and contrasts nine different conceptual models of God: atheism, agnosticism, deism, theism, pantheism, polytheism, henotheism, panentheism, and eschatological panentheism. This essay justifies employment of the model method in theology based on commitments within philosophical hermeneutics, philosophy of science, and the theological understanding of divine transcendence. The result is an array of conceptual models of the divine which have reference, but which make indirect rather than literal claims. Of the analyzed models, this essay defends “eschatological panentheism” as the most satisfying model for Christian constructive theology. This paper was delivered during the APA Pacific 2007 Mini-Conference on Models of God.     

Effects of contour proximity and lightness on Delboeuf illusions created by circumscribed letters

32 observers judged the size of a letter, either an "A" or an "S," which was surrounded by a circle. Both letters were overestimated, but larger surrounding circles reduced the illusion. Decreasing the lightness contrast of the surrounding circle relative to the central letter diminished the illusion. The results suggest that, like the Delboeuf illusion, these circumscribed letters illusions are produced by interactions among size-coding neurons.     

Sleep deprivation selectively impairs memory consolidation for contextual fear conditioning

Many behavioral and electrophysiological studies in animals and humans have suggested that sleep and circadian rhythms influence memory consolidation. In rodents, hippocampus-dependent memory may be particularly sensitive to sleep deprivation after training, as spatial memory in the Morris water maze is impaired by rapid eye movement sleep deprivation following training. Spatial learning in the Morris water maze, however, requires multiple training trials and performance, as measured by time to reach the hidden platform is influenced by not only spatial learning but also procedural learning. To determine if sleep is important for the consolidation of a single-trial, hippocampus-dependent task, we sleep deprived animals for 0–5 and 5–10 h after training for contextual and cued fear conditioning. We found that sleep deprivation from 0–5 h after training for this task impaired memory consolidation for contextual fear conditioning whereas sleep deprivation from 5–10 h after training had no effect. Sleep deprivation at either time point had no effect on cued fear conditioning, a hippocampus-independent task. Previous studies have determined that memory consolidation for fear conditioning is impaired when protein kinase A and protein synthesis inhibitors are administered at the same time as when sleep deprivation is effective, suggesting that sleep deprivation may act by modifying these molecular mechanisms of memory storage.     

Covariation neglect among novice investors

In 4 experiments, undergraduates made hypothetical investment choices. In Experiment 1, participants paid more attention to the volatility of individual assets than to the volatility of aggregated portfolios. The results of Experiment 2 show that most participants diversified even when this increased risk because of covariation between the returns of individual assets. In Experiment 3, nearly half of those who seemingly attempted to minimize risk diversified even when this increased risk. These results indicate that novice investors neglect covariation when diversifying across investment alternatives. Experiment 4 established that naive diversification follows from motivation to minimize risk and showed that covariation neglect was not significantly reduced by informing participants about how covariation affects portfolio risk but was reduced by making participants systematically calculate aggregate returns for diversified portfolios. In order to counteract naive diversification, novice investors need to be better informed about the rationale underlying recommendations to diversify.     

Gender,Employment Status,and Abortion: A Longitudinal Analysis

Building upon extant literature, we examine the influence gender and employment status exert on abortion attitudes among the mass public. Specifically, we assess if men, employed women, and homemaker women view the abortion issue differently and if the same factors account for variation in each group's attitudes toward abortion. Analysis of General Social Survey data from 1973 to 2000 indicates that although homemaker women tend to be more pro-life than do men or working women, the attitudes of all 3 groups exhibit similar changes over time. In addition, our results suggest that the same variables account for variation in abortion attitudes for all 3 groups. Our results suggest that the causes and effects of abortion attitudes do not appear to be gender-specific, but rather are relatively uniform across genders and employment statuses.     

Learning Related and Interpersonal Social Skills Constructs in Two Existing Social Skills Assessments

In the social skills literature it has been identified that both learning related social skills and interpersonal social skills may exist. This study ascertained the views of 16 experts regarding the existence of the two proposed constructs, learning related social skills and interpersonal social skills, within two pre-existing assessments: Preschool and Kindergarten Behavior Scales–2nd edition and Child Behavior Rating Scale. Sixteen experts from Australia (n = 11) and Singapore (n = 5) with pediatric backgrounds in occupational therapy, speech pathology, psychology and early childhood education took part in the study. Experts were asked to sort cards with each of the items from the Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition (66 items in total) into one of two piles (one for learning related social skills and one for interpersonal social skills) and then answered several open ended questions about the clinical utility of these constructs. Preliminary evidence demonstrated the existence of the learning related social skills and interpersonal social skills constructs within the items of the two assessments (Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition). The experts' opinion also suggested the potential clinical benefits of assessing both learning related social skills and interpersonal social skills in preschool-age children. The study results and implications for further research and clinical practice are discussed.
