Is Japan Really Back? The "Abe Doctrine" and Global Governance

Japanese Prime Minister Abe Shinzo has emerged as the “comeback kid” of Japanese politics and in his second term of office is now widely regarded as a rare example of strong leadership as he seeks to arrest and reverse his country’s perceived decline. The strategy to achieve these objectives has come to be known as the “Abe Doctrine,” which represents a radical but risky shift in foreign policy. This article outlines the tenets of the evolving Abe Doctrine and then applies them to the Abe administration’s behaviour in the mechanisms of global governance, a highly pertinent but overlooked example. It argues that although a more strategic and coherent approach to global governance has emerged under Abe than had been previously evident, this has been at the expense of the norm of internationalism that has traditionally shaped Japan’s role

Declining resilience of ecosystem functions under biodiversity loss

The composition of species communities is changing rapidly through drivers such as habitat loss and climate change, with potentially serious consequences for the resilience of ecosystem functions on which humans depend. To assess such changes in resilience, we analyse trends in the frequency of species in Great Britain that provide key ecosystem functions-specifically decomposition, carbon sequestration, pollination, pest control and cultural values. For 4,424 species over four decades, there have been significant net declines among animal species that provide pollination, pest control and cultural values. Groups providing decomposition and carbon sequestration remain relatively stable, as fewer species are in decline and these are offset by large numbers of new arrivals into Great Britain. While there is general concern about degradation of a wide range of ecosystem functions, our results suggest actions should focus on particular functions for which there is evidence of substantial erosion of their resilience

Functional redundancy and sensitivity of fish assemblages in European rivers, lakes and estuarine ecosystems

The impact of species loss on ecosystems functioning depends on the amount of trait similarity between species, i.e. functional redundancy, but it is also influenced by the order in which species are lost. Here we investigated redundancy and sensitivity patterns across fish assemblages in lakes, rivers and estuaries. Several scenarios of species extinction were simulated to determine whether the loss of vulnerable species (with high propensity of extinction when facing threats) causes a greater functional alteration than random extinction. Our results indicate that the functional redundancy tended to increase with species richness in lakes and rivers, but not in estuaries. We demonstrated that i) in the three systems, some combinations of functional traits are supported by non-redundant species, ii) rare species in rivers and estuaries support singular functions not shared by dominant species, iii) the loss of vulnerable species can induce greater functional alteration in rivers than in lakes and estuaries. Overall, the functional structure of fish assemblages in rivers is weakly buffered against species extinction because vulnerable species support singular functions. More specifically, a hotspot of functional sensitivity was highlighted in the Iberian Peninsula, which emphasizes the usefulness of quantitative criteria to determine conservation prioritiesinfo:eu-repo/semantics/publishedVersio

3-Amino­phenyl naphthalene-1-sulfonate

In the title compound, C16H13NO3S, the plane of the naphthalene ring system forms a dihedral angle of 64.66 (10)° with the benzene ring. The mol­ecular structure is stabilized by weak intra­molecular C—H⋯O inter­actions and the crystal packing is stabilized by weak inter­molecular N—H⋯O and C—H⋯O inter­actions and by π–π stacking inter­actions of the inversion-related naphthalene units [centroid–centroid distance of 3.7373 (14) Å]

Climate change and freshwater zooplankton: what does it boil down to?

Recently, major advances in the climate–zooplankton interface have been made some of which appeared to receive much attention in a broader audience of ecologists as well. In contrast to the marine realm, however, we still lack a more holistic summary of recent knowledge in freshwater. We discuss climate change-related variation in physical and biological attributes of lakes and running waters, high-order ecological functions, and subsequent alteration in zooplankton abundance, phenology, distribution, body size, community structure, life history parameters, and behavior by focusing on community level responses. The adequacy of large-scale climatic indices in ecology has received considerable support and provided a framework for the interpretation of community and species level responses in freshwater zooplankton. Modeling perspectives deserve particular consideration, since this promising stream of ecology is of particular applicability in climate change research owing to the inherently predictive nature of this field. In the future, ecologists should expand their research on species beyond daphnids, should address questions as to how different intrinsic and extrinsic drivers interact, should move beyond correlative approaches toward more mechanistic explanations, and last but not least, should facilitate transfer of biological data both across space and time

Direct and converse magnetoelectric effects in Metglas/LiNbO3/Metglas trilayers

Electromechanical and magnetoelectric properties of Metglas/LiNbO3/Metglas trilayers have been studied in the frequency range from 20 Hz to 0.4 MHz. A trilayer of Metglas/PMN-PT/Metglas prepared in the same way was used as a reference. Though PMN-PT has much larger charge piezocoefficients than LiNbO3 (LNO), the direct magnetoelectric voltage coefficient is found to be comparable in both trilayers due to the much lower dielectric permittivity of LNO. The magnitude of the direct magnetoelectric effect in the LNO trilayers is about 0.4 V/cm Oe in the quasistatic regime and about 90 V/cm Oe at the electromechanical resonance. Calculations show that the magnetoelectric properties can be significantly improved (up to 500 V/cm Oe) via controlling the cut angle of LNO, choosing the appropriate thickness ratio of the ferroelectric/ferromagnetic layers and a better bonding between Metglas and LNO. Advantages of using LiNbO3-type ferroelectrics in magnetoelectric composites are discussed. (C) 2013 AIP Publishing LLC

Control of magnetic properties of liquid-crystalline dendron-modified FePt nanoparticles through thermal phase transition for tunable magnetic materials

FePt nanoparticles (NPs) with thermally responsive array structures were prepared by surface modification with a liquid-crystalline phenylethyl ether-type dendron. Dendron modification was carried out in two steps. In the first step, COOH moieties were introduced on the surface of oleyl-modified FePt NPs by ligand exchange using terminal COOH-substituted n-alkyl phosphonic acid. This was followed by the amidation reaction between COOH moieties and the amino-substituted dendron. Infrared spectroscopic measurement and thermogravimetric analysis confirmed that the dendrons were successfully grafted onto the surface of FePt NPs. Transmission electron microscopy also showed an increase in interparticle distance due to dendron modification. Small-angle X-ray scattering (SAXS) revealed that the dendronized NPs pack on an FCC lattice, which melts above 100 °C in thermal response, consistent with the endothermic peak observed in differential scanning calorimetry (DSC). Electron density maps offer detailed insights into the structural organization of the dendronized FePt NP array. These results indicate that the formation of an FCC phase through self-assembly and its thermal transition into a disordered phase enabled dynamic control over magnetic NP arrays. Finally, changes in magnetic properties during thermal phase transition were investigated by a superconducting quantum interference device. The results show certain changes in magnetization behavior introduced by the thermal phase transition. These results demonstrate that dendron modification of FePt NPs enables the introduction of thermal responsiveness in their supramolecular structure and magnetic behavior. The flexible control of magnetic properties is expected to expand the application potential of the magnetic NPs used as building blocks for tunable smart magnetic devices
