Homicide offenders 32 years later – A Swedish population‐based study on recidivism
Authors: Sturup Joakim , Lindqvist Per 
Published: November 2013

ABSTRACTBackgroundThe literature on recidivism by homicide offenders is scarce despite its importance for individuals and for society.AimsTo establish the rate of seriously violent re‐offending among homicide offenders and identify risk factors for such recidivism.MethodsA 1970s incident cohort of all homicide offenders, sane and insane, from two regions of Sweden (N = 153) was followed up until 2007 using data from the national crime register.ResultsTen per cent of the cohort (n = 15) re‐offended. The mean time from index offence to recidivism was 9.4 years. Five people (3%) committed a further homicide, and it was established that another five (3%) offenders had killed before the index offence. Prospective risk factors for violent recidivism were young age, psychotic disorder, male victim, acquainted victim and intoxicated victim.ConclusionsThe prevalence of repeated homicide is higher than previously reported. Victim variables and mental disorder in conjunction with substance abuse appear to be two domains of particular significance for recidivism. Copyright © 2013 John Wiley & Sons, Ltd.

Published: November 2013

AbstractA series of heterometallic [LnIIIxCuIIy] complexes, [Gd2Cu2]n (1), [Gd4Cu8] (2), [Ln9Cu8] (Ln=Gd, 3⋅Gd; Ln=Dy, 3⋅Dy), were successfully synthesized by a one‐pot route at room temperature with three kinds of in situ carbonyl‐related reactions: Cannizzaro reaction, aldol reaction, and oxidation. This strategy led to dysprosium analogues that behaved as single‐molecule magnets (SMMs) and gadolinium analogues that showed significant magnetocaloric effect (MCE). In this study a numerical DFT approach is proposed by using pseudopotentials to calculate the exchange coupling constants in three polynuclear [GdxCuy] complexes; with these values exact diagonalization or quantum Monte Carlo simulations have been performed to calculate the variation of the magnetic entropy involved in the MCE. For the [Dy9Cu8] complexes, local magnetic properties of the DyIII centers have been determined by using the CASSCF+RASSI method.

ABSTRACTMutations in phosphatase and tensin homolog deleted on chromosome 10 (PTEN) are implicated in neuropsychiatric disorders including autism. Previous studies report that PTEN knockdown in neurons in vivo leads to increased spine density and synaptic activity. To better characterize synaptic changes in neurons lacking PTEN, we examined the effects of shRNA knockdown of PTEN in basolateral amygdala neurons on synaptic spine density and morphology by using fluorescent dye confocal imaging. Contrary to previous studies in the dentate gyrus, we find that knockdown of PTEN in basolateral amygdala leads to a significant decrease in total spine density in distal dendrites. Curiously, this decreased spine density is associated with increased miniature excitatory postsynaptic current frequency and amplitude, suggesting an increase in number and function of mature spines. These seemingly contradictory findings were reconciled by spine morphology analysis demonstrating increased mushroom spine density and size with correspondingly decreased thin protrusion density at more distal segments. The same analysis of PTEN conditional deletion in the dentate gyrus demonstrated that loss of PTEN does not significantly alter total density of dendritic protrusions in the dentate gyrus, but does decrease thin protrusion density and increases density of more mature mushroom spines. These findings suggest that, contrary to previous reports, PTEN knockdown may not induce de novo spinogenesis, but instead may increase synaptic activity by inducing morphological and functional maturation of spines. Furthermore, behavioral analysis of basolateral amygdala PTEN knockdown suggests that these changes limited only to the basolateral amygdala complex may not be sufficient to induce increased anxiety‐related behaviors.

Life history of theGlanville fritillary butterfly in fragmented versus continuous landscapes
Authors: Duplouy Anne , Ikonen Suvi , Hanski Ilkka 
Published: November 2013

AbstractHabitat loss and fragmentation threaten the long‐term viability of innumerable species of plants and animals. At the same time, habitat fragmentation may impose strong natural selection and lead to evolution of life histories with possible consequences for demographic dynamics. The Baltic populations of the Glanville fritillary butterfly (Melitaea cinxia) inhabit regions with highly fragmented habitat (networks of small dry meadows) as well as regions with extensive continuous habitat (calcareous alvar grasslands). Here, we report the results of common garden studies on butterflies originating from two highly fragmented landscapes (FL) in Finland and Sweden and from two continuous landscapes (CL) in Sweden and Estonia, conducted in a large outdoor cage (32 by 26 m) and in the laboratory. We investigated a comprehensive set of 51 life‐history traits, including measures of larval growth and development, flight performance, and adult reproductive behavior. Seventeen of the 51 traits showed a significant difference between fragmented versus CL. Most notably, the growth rate of postdiapause larvae and several measures of flight capacity, including flight metabolic rate, were higher in butterflies from fragmented than CL. Females from CL had shorter intervals between consecutive egg clutches and somewhat higher life‐time egg production, but shorter longevity, than females from FL. These results are likely to reflect the constant opportunities for oviposition in females living in continuous habitats, while the more dispersive females from FL allocate more resources to dispersal capacity at the cost of egg maturation rate. This study supports theoretical predictions about small population sizes and high rate of population turnover in fragmented habitats selecting for increased rate of dispersal, but the results also indicate that many other life‐history traits apart from dispersal are affected by the degree of habitat fragmentation.
A Selective Metal‐Mediated Approach for the Efficient Self‐Assembling of Multi‐Component Photoactive Systems
Authors: Iengo Elisabetta , Cavigli Paolo , Gamberoni Marta , Indelli M. Teresa 
Published: November 2013

AbstractWe report on the efficient use of different coordinative affinities to quantitatively construct a three‐component multichromophore system containing one free‐base porphyrin, one aluminium(III) monopyridylporphyrin, and one ruthenium(II) tetraphenylporphyrin in a single step. The AlIII monopyridylporphyrin plays the pivotal role in directing the correct self‐assembly process, and it behaves as the antenna unit for the photoinduced processes of interest. A two‐component system, containing the same free‐base porphyrin and one aluminium(III) tetraphenylporphyrin, was prepared for comparative studies. Both systems are remarkably stable in chlorinated solutions. Their photophysical behaviour was studied in detail by stationary and time‐resolved emission techniques. In the two‐component system, fast and efficient singlet energy transfer from the Al–porphyrin to the free‐base porphyrin is observed; in the three‐component system, upon excitation of the Al–porphyrin, a fast (<250 ps) electron transfer process from the Ru–porphyrin to the aluminium–porphyrin is observed.
Square and Butterfly Tetranuclear [Co2Ln2] Clusters Built from the Same Building Blocks but Displaying Different Magnetic Properties: Structural Variation by Means of Solvent and the Radii of Ln3+ Ions

Published: November 2013

AbstractTwo series of tetranuclear [Ln2Co2] clusters were built from the same [Co(CDTA)]2– building blocks but have different metal skeletons: square 1Ln compounds {[Ln2Co2(CDTA)2(μ4‐OH)(DMF)2(H2O)6]·ClO4·1.5H2O; Ln = La, Gd, and Dy} with a μ4‐OH– bridged Ln–Co–Ln–Co arrangement, and two μ3‐OH–‐bridged “butterfly” 2Ln compounds {[Ln2Co2(CDTA)2(μ3‐OH)2(H2O)6]·6H2O; Ln = Gd, Tb, Dy, and Y} with two Ln3+ ions as the “body” and two Co2+ ions as “wings”. They were prepared from the solvothermal reactions of trans‐1,2‐diaminocyclohexane‐N,N,N′,N′‐tetraacetic acid (H4DCTA), Ln(ClO4)3, and Co(ClO4)2 in DMF/H2O or H2O solvent. Their syntheses are mainly controlled by the solvent and the radii of Ln3+ ions. Light Ln3+ ions with big radii are favorable for the formation of square complexes, whereas heavy Ln3+ ions (including Y3+) with small radii promote the formation of butterfly ones. Remarkably, the middle Ln3+ ions are favorable for the formation of both structures, and in these cases the reactions are controlled by solvent (H2O or H2O + DMF). Magnetic analyses reveal the antiferromagnetic interactions between the two Co2+ ions in 1La and 2Y. Interestingly, other butterfly clusters (2Gd, 2Tb, 2Dy) show dominant ferromagnetic interactions, whereas the other square clusters (1Gd, 1Dy) show overall antiferromagnetic interactions. Details of the magnetic interaction between the metal ions are discussed.
Reaction of Tri(2‐pyridyl)phosphine with Electron‐Deficient Alkynes in Water: Stereoselective Synthesis of Functionalized Pyridylvinylphosphine Oxides

Published: November 2013

AbstractThe reaction of tri(2‐pyridyl)phosphine with electron‐deficient alkynes in water proceeds under mild conditions (40–45 °C, without catalyst, 4–5 h) with liberation of pyridine to give (E)‐pyridylvinylphosphine oxides in 45–56 % yields, the only exception being the reaction with cyanophenylacetylene, which affords the corresponding vinylphosphine oxide of Z‐configuration in 40 % yield. The reaction is likely triggered by the zwitterion, the adduct of tri(2‐pyridyl)phosphine to the electrophilic acetylenes, the carbanionic center of which is then neutralized by a proton from water. The intermediate phosphonium hydroxide finally decomposes to the product.
Correcting for ascertainment bias in the COGA data set
Authors: Comuzzie Anthony G. , Williams Jeff T. 
Published: November 2013

AbstractThe effects of several corrections for ascertainment bias on a linkage result in the COGA data are examined. A correction that models the complete ascertainment protocol markedly reduces the evidence for linkage. Different partial corrections increase the linkage signal and recover good estimates of the population trait prevalence, but do not represent adequately the complexity of the COGA ascertainment scheme. Evidently the present size of the COGA data set cannot support a complete correction for ascertainment bias, but an effective partial correction can and should be implemented.
Power loss for multiallelic transmission/disequilibrium test when errors introduced: GAW11 simulated data
Authors: Gordon Derek , Matise Tara C. , Heath Simon C. , Ott Jurg 
Published: November 2013

AbstractMany researchers are considering the use of transmission/disequilibrium tests (TDT) for trios of genotypes (father, mother, child) as a method for localizing genes associated with complex diseases. We evaluate the effect of random errors (allele changes) in trios on the power to detect linkage. For a marker in the simulated data set, one allele is associated with the fictitious disease in a certain subpopulation. For the data as given (no errors), our power to detect linkage using the multiallelic TDT (TDTmhet) is 68% (critical p‐value set at 0.0001). We introduce errors into trios at various rates (1%, 5%, or 10%), remove only trios displaying mendelian inconsistencies, and recalculate power to detect linkage. Our principal finding is that there is power loss to detect linkage with the TDTmhet when errors are introduced. We observe power losses of 8%, 16%, and 48% for error rates of 1%, 5%, and 10%, respectively. To determine the source of the power loss, we perform Monte Carlo simulations. At the 1% and 5% rates, we conclude that power loss is due primarily to loss in sample size. At the 10% rate, we observe substantial power loss due to error introduction in addition to sample size reduction. We also determine, given a particular error rate, the probability that we detect errors if we use only mendelian consistency as a check. We find that the mean detection rates for the data sets with 1%, 5%, or 10% error rates are 58%, 60%, and 62%, respectively. As a result, the apparent error rate appears to be almost half the true error rate. Based on these results, we recommend that researchers maintain error rates below 5% when using the TDTmhet for linkage, use additional methods beyond mendelian consistency checks when searching for errors in their data, and modify sample size calculations when accounting for errors in their genotype data.
Vein Palygorskites in Israel and Sinai; Their Origin and Symmetry

Published: November 2013

AbstractThree palygorskites in veins have been found in Israel and a fourth in the Sinai peninsula. They all have a mountain cork appearance, and are mixed with quartz, montmorillonite and calcite. Three of them are presumably hydrothermal and monoclinic. The fourth is probably sedimentary and is orthorhombic. It is suggested that the orthorhombic ‐monoclinic transition is an order‐disorder phenomenon.
Structural Changes and Isomorphic Substitution in Illites from Limestones of Variable Degrees of Metamorphism
Authors: Gavish E. , Reynolds R. C. 
Published: November 2013

AbstractEleven samples of illites were separated from limestones which have undergone variable degrees of metamorphism and analyzed by X‐ray diffraction to give twelve orders of the (001) reflections. The observed structure factors were calculated with a computer and compared to calculated structure factors of a hypothetical model through a process of “refinement”. The variable parameters in the process of “refinement” were: the distance of OH, Si and O from the center of the unit cell, the temperature coefficient, and the amount of K+ and Fe+3 in the lattice of the unit cell. A one‐dimensional Fourier synthesis calculated the electron densities along the C axis within the unit cell. The percent 2M polymorph in the illites, as well as the oxygen isotope ratio of the limestones from which the illites were extracted, was also calculated. These two parameters were used as indicators of the degree of metamorphism of the samples collected. There is an inverse correlation between the proportion of 2M polymorphs and the O18/O16 ratio. There is no clear correlation between the amount of K+ in the lattice and the degree of metamorphism of the samples. There is an increase of Fe+3 substituted in the octahedral layer of the illite, with an increased degree of metamorphism of the limestones.
A Rapid Microdetermination of Water in Chlorinated Hydrocarbons by Gas Chromatography
Authors: Joseph H. 
Published: November 2013

AbstractA fast and sensitive gas chromatographic procedure for the control of moisture in chlorinated hydrocarbons at the ppm level is described. The basic features are a combination of two types of polyaromatic beads as column packing, locally produced hydrogen as carrier gas, and a backflushing system. The latter reverses the carrier gas flow after elution of the water peak at increased pressure. The instrument is thus readied for subsequent analyses at intervals of 2–3 min. The system can be used for moisture analyses in most gases and liquids. It is particularly applicable where a large number of samples have to be checked continually and instant results are required.
