The Federalist offers important lessons in how to cope with the current gridlock in American government

The recent government shutdown and political gridlock that has gripped Washington DC has led to many calls for Republicans and Democrats to move beyond politics. David Brian Robertson looks back to The Federalist, which he argues offer us lessons in how to break that gridlock. He writes that The Federalist shows us that we need to embrace politics because it is the force that drives government through negotiation and compromise

Replication of child sexual abuse in males

This thesis reviewed the major methodological, theoretical and empirical research literature pertaining to replication of child sexual abuse (CSA) in males. The review concluded that a dearth of scientific evidence exists in support of child sexual abuse replication. The aim of the current study was to empirically examine the relationship between childhood sexual victimization experiences and adult offending behaviour in males. Some 45 male incarcerated child sexual offenders undergoing treatment were interviewed about their childhood sexual experiences and their offence history. Some 78% of the sample were sexually abused as children and data from this group were used to study CSA replication. Simple replication of any characteristic from the first, last or all CSA experience(s) was not apparent from simple correlation analysis. Such characteristics included age of victim, gender, victim-offender relationship, sexual act and force associated with abuse. Multivariate analysis revealed that the gender of the subject's first victim was able to be predicted from a mean gender rating of each subject's perpetrators and a mean physical rating of each subject's entire child sexual abuse history. This function was able to correctly predict the gender of the first victim of 79% of the abused sample. Gender replication was found to be significantly modulated by happy, physically pleasant and physically intrusive child sexual abuse experiences. It is suggested that the results are more supportive of social learning explanations than psychodynamic models of CSA replication. The need for more sophisticated, multivariate analysis of replication is stressed. Finally, the results are discussed in terms of their implications for future research and treatment of male victims and adult perpetrators of child sexual abuse

An exploration of alternative visualisations of the basic helix-loop-helix protein interaction network

Background: Alternative representations of biochemical networks emphasise different aspects of the data and contribute to the understanding of complex biological systems. In this study we present a variety of automated methods for visualisation of a protein-protein interaction network, using the basic helix-loop-helix ( bHLH) family of transcription factors as an example. Results: Network representations that arrange nodes ( proteins) according to either continuous or discrete information are investigated, revealing the existence of protein sub-families and the retention of interactions following gene duplication events. Methods of network visualisation in conjunction with a phylogenetic tree are presented, highlighting the evolutionary relationships between proteins, and clarifying the context of network hubs and interaction clusters. Finally, an optimisation technique is used to create a three-dimensional layout of the phylogenetic tree upon which the protein-protein interactions may be projected. Conclusion: We show that by incorporating secondary genomic, functional or phylogenetic information into network visualisation, it is possible to move beyond simple layout algorithms based on network topology towards more biologically meaningful representations. These new visualisations can give structure to complex networks and will greatly help in interpreting their evolutionary origins and functional implications. Three open source software packages (InterView, TVi and OptiMage) implementing our methods are available

textabstractThe Drosophila protein Sex-lethal (Sxl) contains two RNP consensus-type RNA-binding domains (RBDs) separated by a short linker sequence. Both domains are essential for high-affinity binding tO the single-stranded polypyrimidine tract (PPT) within the regulated 3' splice site of the transformer (tra) pre- mRNA. In this paper, the effect of RNA binding to a protein fragment containing both RBDs from Sxl (Sxl-RBD1+2) has been characterized by heteronuclear NMR. Newly complete (85-90%) backbone resonance assignments have been obtained for unbound and RNA-bound states of Sxl-RBD1+2. A comparison of amide 1H and 15N chemical shifts between free and bound states has highlighted residues which respond to RNA binding. The β-sheets in both RBDs (RBD1 and RBD2) form an RNA interaction surface, as has been observed in other RBDs. A significant number of residues display different behavior when comparing RBD1 and RBD2. This argues for a model in which RBD1 and RBD2 of Sxl have different or nonanalogous points of interaction with the tra PPT. R142 (in RBD2) exhibits the largest chemical shift change upon RNA binding. The role of R142 in RNA binding was tested by measuring the K(d) of a mutant of Sxl-RBD1+2 in which R142 was replaced by alanine. This mutant lost the ability to bind RNA, showing a correlation with the chemical shift difference data. The RNA-binding affinities of two other mutants, F146A and T138I, were also shown to correlate with the NMR observations

Rapid Oscillations in Cataclysmic Variables. XVI. DW Cancri

We report photometry and spectroscopy of the novalike variable DW Cancri. The spectra show the usual broad H and He emission lines, with an excitation and continuum slope characteristic of a moderately high accretion rate. A radial-velocity search yields strong detections at two periods, 86.1015(3) min and 38.58377(6) min. We interpret these as respectively the orbital period P_orb of the binary, and the spin period P_spin of a magnetic white dwarf. The light curve also shows the spin period, plus an additional strong signal at 69.9133(10) min, which coincides with the difference frequency 1/P_spin-1/P_orb. These periods are stable over the 1 year baseline of measurement. This triply-periodic structure mimics the behavior of several well-credentialed members of the "DQ Herculis" (intermediate polar) class of cataclysmic variables. DQ Her membership is also suggested by the mysteriously strong sideband signal (at nu_spin-nu_orb), attesting to a strong pulsed flux at X-ray/EUV/UV wavelengths. DW Cnc is a new member of this class, and would be an excellent target for extended observation at these wavelengths.Comment: PDF, 28 pages, 6 tables, 9 figures; accepted, in press, to appear June 2004, PASP; more info at http://cba.phys.columbia.edu

A User Driven Dynamic Circuit Network Implementation

The requirements for network predictability are becoming increasingly critical to the DoE science community where resources are widely distributed and collaborations are world-wide. To accommodate these emerging requirements, the Energy Sciences Network has established a Science Data Network to provide user driven guaranteed bandwidth allocations. In this paper we outline the design, implementation, and secure coordinated use of such a network, as well as some lessons learned

Frontal White Matter Integrity in Adults with Down Syndrome with and without Dementia

Adults with Down syndrome (DS) are at high risk for developing Alzheimer\u27s disease after the age of 40 years. To detect white matter (WM) changes in the brain linked to dementia, fractional anisotropy (FA) from diffusion tensor imaging was used. We hypothesized that adults with DS without dementia (DS n = 10), DS with dementia (DSAD n = 10) and age matched non-DS subjects (CTL n = 10) would show differential levels of FA and an association with scores from the Brief Praxis Test and the Severe Impairment Battery. WM integrity differences in DS compared with CTL were found predominantly in the frontal lobes. Across all DS adults, poorer Brief Praxis Test performance correlated with reduced FA in the corpus callosum as well as several association tracts, primarily within frontoparietal regions. Our results demonstrate significantly lower WM integrity in DS compared with controls, particularly in the frontal tracts. DS-related WM integrity reductions in a number of tracts were associated with poorer cognition. These preliminary results suggest that late myelinating frontal pathways may be vulnerable to aging in DS
