Requencies and relations of body piercing and sexual experience in college students

This research examined the relation between having a body piercing and having engaged in premarital sexual intercourse. Data were gathered from a convenience sample of 450 college students. 72% were women; 85% were ages 18 to 22 years (M=20.9, SD=4.5), 80% were Euro-American. Women with piercings reported substantively and significantly greater frequency of sexual activity than college students without piercings. There were no significant differences in sexual experience between men with piercings and those without. These findings differ from previous research comparing the sexual activity of college students with and without tattoos.     

Learning-induced axonal remodeling: evolutionary divergence and conservation of two components of the mossy fiber system within Rodentia

Damage to the hippocampal formation results in profound impairments in spatial navigation in rats and mice leading to the widely accepted assumption that the hippocampal cellular and molecular memory mechanisms of both genera are conserved. Recently our group has shown in two rat strains that hippocampal-dependent training in the water maze specifically induces robust 'sprouting' of granule cell suprapyramidal mossy fiber axon terminal fields. Here we sought to investigate whether the pronounced remodeling of adult hippocampal circuitry observed in the rat is also present in the mouse motivated by the thought that subsequent studies using genetically-engineered mice could then be implemented to explore the molecular mechanisms underlying training-dependent axonal growth in adult rodents. However, in contrast to Wistar rats, no changes in the Timm's-stained area of mossy fiber terminal fields (MFTFs) were observed in C57BL/6J or 129Sv/EmsJ inbred wild-type mice after water maze training. Neither extending the duration of training nor scaling down the size of the apparatus was able to induce sprouting in mouse mossy fiber pathways. Though there may be similarities in the ultimate output of the hippocampus of rats and mice as inferred from lesion studies, the current results, as well as differences in learning and memory characteristics between the two genera, suggest that the way in which the component circuitry functions is likely to be different; a not too surprising conclusion given the substantial evolutionary distance between them (>20 million years). The present findings afford an opportunity for uncovering linkages between evolutionarily significant alterations in hippocampal circuitry in relation to genera-specific information storage requirements.     

The trauma of evil and the traumatological conception of forgiveness

In recent years there has been widespread interest in assimilating forgiveness into a rational conception of the moral life. This project usually construes forgiveness as a way of “moving past” evil and resuming the moral narrative it disrupted. But to develop a philosophical sound conception of forgiveness, we must recognize that moral evil is world-shattering and cannot be assimilated into the moral narrative of our lives. It is not an event that happens in one’s world but to one’s world. In this respect it is similar to death as Heidegger has described it. But, contrary to what Heidegger implies, evil is more traumatic than death because, unlike the latter, it shatters moral reasoning and moral narrative. Evil is a monstrosity; it traumatizes historical existence by impossibilizing the future. A philosophical account of forgiveness must therefore be traumatological: recognizing the traumatizing impact that evil has on historicity, it has provide us a heuristic that will help us to imagine the unimaginable possibility of transforming historical horror into good.     

Tone production deficits in nonfluent aphasic Chinese speech

Previous studies demonstrating a right hemisphere lateralization of musical, tonal, and intonational stimuli had suggested that in aphasic tone language speakers, the tonal phonemes might be subject to a lesser degree of deficit than consonantal phonemes. Using a word repetition task, this research demonstrates that left-damaged nonfluent aphasic speakers of Chinese experience a tonal production deficit which is both quantitatively and qualitatively equivalent to the deficit experienced by these speakers in the production of consonants. It is suggested that in tone languages, lexical specification of tone contour information results in left hemisphere lateralization of that information, thus making the tonal phonemes vulnerable to left hemisphere damage.
