The Phenomenon of Intrusive Thoughts in Yejide Kilanko’s Daughters Who Walk This Path
Authors: Dodhy Shamaila 
Published: November 2017

Hegemonic masculinity, with patriarchal supremacy and female subservience are the norms of many African societies. Suffering in silence goes along with the traditional place of woman in African societies as they observe sexist hierarchy of power. Physical attack and its wounds flourish in an atmosphere of secrecy and silence. Silence to such problems escalates psychological distress, casting adverse effects on the individual. Silence leaves overt and covert markings on the psyche. Intrusive thoughts are one of symptoms among nightmares, flashbacks, fear, and anxiety of psychological trauma. No previous research examined the intrusion of intrusive thoughts which disturb the life of Morayo. The article addresses this gap as this symptom of trauma makes life difficult for a girl whose trust is violated by a kinsman. This work accentuates that speaking-out can end a false sense of shame that survivors often carry. Speech will agitate legal change, bring about advancement in therapeutic approaches, and undermine social myths about sexual assault which will promote acceptance for the survivors.

Published: October 2017

BackgroundSkin-to-skin contact (SSC) is an important factor to consider in the care of late preterm infants (born between 34 0/7 and 36 6/7 completed weeks of gestation). The literature suggests that SSC between preterm infants and their mothers facilitates breastfeeding. However, more studies are needed to explore potential dose-response effects between SSC and breastfeeding as well as studies that explicitly investigate SSC by fathers among late preterm infants. The aim was to investigate the duration of healthy late preterm infants’ SSC with the mother and father, respectively, during the first 48 h after birth and the associations with breastfeeding (exclusive/partial at discharged), clinical and demographic variables.MethodsThis was an observational cohort study in which parents to healthy late preterm infants, born between 34 5/7 and 36 6/7 completed weeks of gestation, recorded duration of SSC provided by mother and father, respectively. Demographic and clinical variables were retrieved from the medical records and were used as predictors. Multiple linear regression analysis was used to assess the association between the predictors and the outcome, SSC (hours), separately for mothers and fathers.ResultsThe mean (standard deviation [SD]) time per day spent with SSC with mothers (n = 64) and fathers (n = 64), was 14.7 (5.6) and 4.4 (3.3) hours during the first day (24 h) after birth and 9.2 (7.1) and 3.1 (3.3) hours during the second day (24 h), respectively. Regarding SSC with mothers, no variable was significantly associated with SSC during the first day, while the mean (95% confidence interval [CI]) time of SSC during the second day was 6.9 (1.4–12.4) hours shorter for each additional kg of birthweight (p = 0.014). Concerning SSC with fathers, the mean (95% CI) time of SSC during the first day was 2.1 (0.4–3.7) hours longer for infants born at night (p = 0.015), 1.7 (0.1–3.2) hours longer for boys (p = 0.033), 3.2 (1.2–5.2) hours longer for infants born by caesarean section (p = 0.003), and 1.6 (0.1–3.1) hours longer for infants exclusively breastfed at discharge (p = 0.040). During the second day, the mean (95% CI) time of SSC with fathers was 3.0 (0.6–5.4) hours shorter for each additional kg of birthweight (p = 0.014), 2.0 (0.5–3.6) hours longer for infants born during night-time (p = 0.011), 2.9 (1.4–4.4) hours longer if the mother was primipara (p < 0.001), and 1.9 (0.3–3.5) hours shorter if supplementary artificial milk feeds were given. None of the other predictors, i.e., mother’s age, gestational age, or induction of labor were significantly associated with infants’ SSC with mothers or fathers during any of the first two days after birth.ConclusionFuture studies are warranted that investigate duration of SSC between late preterm infants and their parents separately and the associations with breastfeeding and other variables of clinical importance.

Particle Precipitation Effects on Convection and the Magnetic Reconnection Rate in Earth's Magnetosphere
Authors: Jensen Joseph B. , Raeder Joachim , Maynard Kristofor , Cramer W. Douglas 
Published: October 2017

AbstractWe investigate the connection between particle precipitation in the ionosphere to both the subsolar distance of the magnetopause and the reconnection rate using the OpenGGCM‐CTIM‐RCM model. We simulated two events, a calm period on 4 May 2005 and a storm period on 17 March 2013. We find that scaling the precipitation energy flux by several orders of magnitude, conductivities in the auroral oval are influenced which, in turn, influence the cross polar cap potentials. With the change in conductance, magnetospheric convection is enhanced or reduced, and the location of the subsolar distance of the magnetopause can change by up to one RE. The investigation of the reconnection rate for the varying precipitation simulations using the Hesse‐Forbes‐Bern method shows that particle precipitation affects the magnetic reconnection rate in these two events. The most notable differences, up to 40%, occur on short time scales, that is, hours. A relation for longer time scales (tens of hours) between precipitation and reconnection for these two events is more difficult to ascertain. Differences in cross polar cap potential (CPCP) and R can be explained by viscous interactions and polar cap saturation. We find that when precipitation was decreased, resulting in low polar conductance, viscous interactions are strong and CPCP is higher than R. For high precipitation, high conductance cases the polar cap is in the saturation regime and CPCP is lower than R. We find hemispheric asymmetries in the cross polar cap potential and in the calculated reconnection rate derived from the Northern and Southern Hemispheres.

AbstractThere was a geomagnetic storm on 6–8 March 2016, in which Van Allen Probes A and B separated by ∼2.5 h measured increase of relativistic electrons with energies approximately several hundred keV to 1 MeV. Simultaneously, chorus waves were measured by both Van Allen Probes and Magnetospheric Multiscale (MMS) mission. Some of the chorus elements were rising tones, possibly due to nonlinear effects. These measurements are compared with a nonlinear theory of chorus waves incorporating the inhomogeneity ratio and the field equation. From this theory, a chorus wave profile in time and one‐dimensional space is simulated. Test particle calculations are then performed in order to examine the energization rate of electrons. Some electrons are accelerated, although more electrons are decelerated. The measured time scale of the electron increase is inferred to be consistent with this nonlinear theory.

Published: October 2017

AbstractOrganic semiconductor materials with high charge‐carrier mobility and high luminescence are promising for fabricating high‐performance organic light‐emitting transistors and electrically pumped organic laser diodes. Some derivatives with an anthracene core show both characteristics; however, independently controlling the size and the thickness of single‐crystal films is challenging. Here, 2D and 3D crystal formation is demonstrated by using an air‐stable organic semiconductor, 2,6‐bis[4‐ethylphenyl]anthracene (BEPAnt). The shape of the single‐crystal films can be changed from about 0.10 mm in diameter and 400 nm in thickness to 1.0 mm in diameter and 50 nm in thickness by controlling the growth conditions using saturation–supersaturation vapor pressure curves. The in‐plane growth rate increases by ten times while the out‐of‐plane growth rate decreases to about 1/8 as the growth temperature increases from 210 to 250 °C. Single‐crystal organic field‐effect transistors based on BEPAnt show isotropic mobilities as high as 7.2 cm2 V−1 s−1.

AbstractFlexible, lightweight, and wearable devices are currently attracting tremendous interest in the field of advanced electronics. In this work, novel 1D, flexible, coaxial‐structured, bright and colorful alternating current electroluminescent (ACEL) fibers consisting of AgNW‐based electrodes, a ZnS phosphor layer, and silicone dielectric and encapsulation layers are designed and fabricated through a simple protocol. This facile all‐solution‐based fabrication protocol enables scalable production of long ACEL fibers (>12 cm). Stemming from the rational design and facile fabrication process, the as‐prepared ACEL fibers exhibit uniform, bright, and angularly independent luminance (up to 202 cd m−2 @ 195 V and 2 kHz). Benefiting mainly from the robust AgNW‐based electrodes and versatile silicone, the ACEL fibers exhibit additionally excellent flexibility and mechanical stability, being capable to maintain ≈91% of luminance after 500 bending‐recovery cycles, as well as mitigated luminance degradation after continuous work in ambient. The proper length combined with superb mechanical properties makes the ACEL fibers readily weavable. Most notably, the isolating, hydrophobic, and biocompatible silicone encapsulation layer endows the ACEL fibers unprecedented wearability. Eventually, a proof‐of‐concept ACEL fabric is demonstrated by weaving the as‐prepared long ACEL fibers, to show the future perspective of directly weaving ACEL fibers into densely arrayed wearable functional cloths.

Authors: Veeranna Kirana Devarahosahalli , Das Kanak Kanti , Baskaran Sundarababu 
Published: October 2017

AbstractA novel and efficient one‐pot method has been developed for the synthesis of cyclopropane‐fused bicyclic amidines on the basis of a CuBr2‐mediated oxidative cyclization of carbanions. The usefulness of this unique multicomponent strategy has been demonstrated by the use of a wide variety of substrates to furnish novel cyclopropane‐containing amidines with a quaternary center in very good yields. This ketenimine‐based approach provides straightforward access to biologically active and pharmaceutically important 3‐azabicyclo[n.1.0]alkane frameworks under mild conditions. The synthetic power of this methodology is exemplified in the concise synthesis of the pharmaceutically important antidepressant drug candidate GSK1360707 and key intermediates for the synthesis of amitifadine, bicifadine, and narlaprevir.

Published: October 2017

AbstractOxygen‐containing heterocycles are a common structural motif in polyketide natural products and contribute significantly to their biological activity. Here, we report structural and mechanistic investigations on AmbDH3, a polyketide synthase domain with dual activity as dehydratase (DH) and pyran‐forming cyclase in ambruticin biosynthesis. AmbDH3 is similar to monofunctional DH domains, using H51 and D215 for dehydration. V173 was confirmed as a diagnostic residue for cyclization activity by a mutational study and enzymatic in vitro experiments. Similar motifs were observed in the seemingly monofunctional AmbDH2, which also shows an unexpected cyclase activity. Our results pave the way for mining of hidden cyclases in biosynthetic pathways. They also open interesting prospects for the generation of novel biocatalysts for chemoenzymatic synthesis and pyran‐polyketides by combinatorial biosynthesis.

Published: October 2017

Vanadium(IV) Schiff base complexes (VOL1‐VOL3) were synthesized and characterized by elemental analysis, various spectral methods and single crystal XRD studies. Structural analysis of VOL2 reveals that the central vanadium ion in the complex is six coordinate with distorted octahedral geometry. Density functional theory (DFT) and time dependent (TD‐DFT) studies were used to understand the electronic transitions observed in the complexes in UV–Vis spectra. The electrochemical behavior of the complexes was investigated in acetonitrile medium exhibit quasi‐reversible one electron transfer. The DNA and BSA protein binding interaction of vanadium complexes has been explored by UV–Vis and fluorescence spectral methods and viscosity measurements reveal that the complexes interact with CT‐DNA through intercalation mode and follows the order VOL1 < VOL3 < VOL2. The complexes exhibit binding interactions with BSA protein. The complexes act as chemical nuclease and cleave DNA in the presence of H2O2. The 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay was used to evaluate the radical scavenging activity demonstrate the antioxidant property of the complexes. The antimicrobial activity was screened for several microorganisms, Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli. The mimicking of vanadium haloperoxidase was investigated by the bromination of the organic substrate phenol red by vanadium complexes in the presence of bromide and H2O2.

Published: October 2017

A kind of Metal–organic framework (MOF) composite namely Cu‐BTC@Fe3O4 (BTC = 1,3,5‐benzenetricarboxylate) was prepared and showed good catalytic activity toward the reduction of nitroarenes. This reaction proceeded smoothly under mild reaction conditions in aqueous medium using sodium borohydride as the reduction agent, affording the corresponding anilines in good to excellent yields. In addition, the catalyst could be easily recovered with an external permanent magnet and be reused for successive six runs with slight decrease in its activity.

Mesoporous chitosan‐grafted iron tetra (4‐carboxyphenyl) porphyrin catalyst (Fe TCPP/mesp‐CTS) was prepared and investigated as a practical model for the nano‐cavity and coordinate regulation‐catalysis(CRC) function in cytochrome P‐450 enzyme. Fe TCPP/mesp‐CTS was characterized by X‐ray Diffraction(XRD), Thermogravimetry(TG), Ultraviolet–visible spectroscopy(UV‐Vis), Ultraviolet–visible–Diffuse reflectance spectroscopy(UV‐DRS), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT‐IR), and X‐ray photoelectron spectroscopy(XPS) techniques. The catalytic activity of Fe TCPP/mesp‐CTS for ethylbenzene oxidation was investigated and it was proved to be a better catalyst than Fe TCPP/macp‐CTS based on the ethylbenzene conversion, turnover numbers(TON), and the reusability. These results are attributed to the mesocavity and CRC of amino group in Fe TCPP/mesp‐CTS. The highest ethylbenzene conversion and yields of ketone and alcohol were 24.4% and 18.2%, respectively.

Published: October 2017

ABSTRACTHydrogels usually have a smaller mechanical strength and toughness than generic polymeric materials. Therefore, many studies report improvements for mechanical properties of hydrogels by preparing double‐network hydrogels, nanocomposite hydrogels, and nanostructured hydrogels. In this study, interpenetrating‐type dually‐crosslinked hydrogels were prepared via free radical crosslinking polymerization of acrylamide monomers in the presence of poly(aspartic acid) and subsequent immersion in a metal ion containing aqueous solution to induce extra physical crosslinking through ionic or coordination bonding. Using this approach, the mechanical properties of inherently weak and brittle homopolymer gels could be improved via interpenetrating the double network formed by both covalent bonding and metal coordination‐assisted reversible physical crosslinks. The preparation, swelling behavior, morphology, and mechanical properties of these hydrogels are presented. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45925.

Published: October 2017

AbstractIntroductionDedication and training to a profession results in a certain level of expertise. This expertise, like any other skill obtained in our lifetime, is encoded in the brain and may be reflected in our brain's connectome. This property can be observed by mapping resting state connectivity. In this study, we examine the differences in resting state functional connectivity in four major networks between professional “Baduk” (Go) players and normal subjects.MethodsResting state fMRI scans were acquired for professional “Baduk” (Go) players and normal controls. Major resting state networks were identified using independent component analysis and compared between the two groups. Networks which were compared include the default mode network, the left and right fronto‐parietal network, and the salience network.ResultsWe found that normal subjects showed increased connectivity within certain areas of each target network. Professional players, however, showed higher connectivity to regions outside the traditional regions of each given network. Close examination of these regions revealed that regions shown to have higher connectivity in professional players have been revealed to be relevant in expertise for board games.ConclusionThe findings in this study suggest that continuous training results in greater integration between regions and networks, which are necessary for high‐level performance. The differences observed in our study between normal controls and professional players also shed light on the difference in brain connectivity which can arise through lifestyle and specialization in a specific field.
Green Innovation, Managerial Concern and Firm Performance: An Empirical Study
Authors: Tang Mingfeng , Walsh Grace , Lerner Daniel , Fitza Markus A. , Li Qiaohua 
Published: October 2017

AbstractExtant literature, while often suggesting a positive link between green innovation and firm performance, is inconclusive. Moreover, the possibly moderating role of management has not been sufficiently considered. Using a unique dataset sampling 188 manufacturing firms in China, we examine how managerial concern (for green issues) moderates the relationship between green innovation and firm performance. We find that green process innovation and green product innovation both significantly (positively) predict firm performance, when not considering managerial concern for the environment. Once managerial concern is included, we observe that it compounds the positive effect of green process innovation on firm performance – but not product innovation, which no longer explains significant unique variance in firm performance. The findings hold various implications for future research and business policy. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
