RELIGION AFTER THE STATE: SECULAR SOTERIOLOGIES AT THE BIRTH OF SOUTH SUDAN
Authors: Salomon Noah
Published: October 2014

This article examines South Sudan's experiment in creating a secular state out of the ashes of the professedly Islamic republic from which it seceded in 2011. South Sudanese political actors presented secularism as a means of redeeming the nation from decades of religious excess in which the government conflated political imperative with theological ambition, claiming to save the nation from its woes through the unifying force of Islam. However, secularism as an alternative soteriology—one that contended that it is only through political nonalignment in regards to religion that the public could be saved from the problems that plagued its predecessor—quickly became an object of contention itself, read by many South Sudanese to be anything but neutral. This article interrogates the secular promise of mediating religious diversity through exploring the tensions that have arisen in its fulfillment at the birth of the world's newest republic.
Foreign Military Presence and the Changing Practice of Sovereignty: A Pragmatist Explanation of Norm Change
Authors: SCHMIDT SEBASTIAN
Published: October 2014

Recent years have seen an increasing interest among international relations scholars in applications of pragmatist thought. Few works, however, have gone beyond discussing the epistemological and methodological implications of pragmatism. This article draws on a pragmatist understanding of human action to develop a novel explanation of norm change in contexts not amenable to more common analytical approaches. Specifically, concepts derived from pragmatism help explain how the creative recombination of practices by actors in response to changes in the material and social context of action can transform largely tacit notions of appropriate behavior. The article demonstrates the value of the approach by explaining the origin of a common contemporary security practice unknown prior to the Second World War and incompatible with the then-prevailing norms of sovereignty: the long-term, peacetime presence of one state's military on the territory of another equally sovereign state.
Beyond Keeping Peace: United Nations Effectiveness in the Midst of Fighting
Authors: HULTMAN LISA , KATHMAN JACOB , SHANNON MEGAN
Published: October 2014

While United Nations peacekeeping missions were created to keep peace and perform post-conflict activities, since the end of the Cold War peacekeepers are more often deployed to active conflicts. Yet, we know little about their ability to manage ongoing violence. This article provides the first broad empirical examination of UN peacekeeping effectiveness in reducing battlefield violence in civil wars. We analyze how the number of UN peacekeeping personnel deployed influences the amount of battlefield deaths in all civil wars in Africa from 1992 to 2011. The analyses show that increasing numbers of armed military troops are associated with reduced battlefield deaths, while police and observers are not. Considering that the UN is often criticized for ineffectiveness, these results have important implications: if appropriately composed, UN peacekeeping missions reduce violent conflict.

An increasing number of children are exhibiting features of the metabolic syndrome (MetS) including abdominal fatness, hypertension, adverse lipid profile and insulin resistance. Healthy eating practices during school hours may improve the cardiometabolic profile, but there is a lack of evidence. In the present study, the effect of provision of school meals rich in fish, vegetables and fibre on a MetS score (primary outcome) and on individual cardiometabolic markers and body composition (secondary outcomes) was investigated in 834 Danish school children. The study was carried out as a cluster-randomised, controlled, non-blinded, cross-over trial at nine schools. Children aged 8–11 years received freshly prepared school lunch and snacks or usual packed lunch from home (control) each for 3 months. Dietary intake, physical activity, cardiometabolic markers and body composition were measured at baseline and after each dietary period. The school meals did not affect the MetS score (P= 1·00). However, it was found that mean arterial pressure was reduced by 0·4 (95 % CI 0·0, 0·8) mmHg (P= 0·04), fasting total cholesterol concentrations by 0·05 (95 % CI 0·02, 0·08) mmol/l (P= 0·001), HDL-cholesterol concentrations by 0·02 (95 % CI 0·00, 0·03) mmol/l, TAG concentrations by 0·02 (95 % CI 0·00, 0·04) mmol/l (bothP< 0·05), and homeostasis model of assessment-insulin resistance by 0·10 (95 % CI 0·04, 0·16) points (P= 0·001) compared with the control diet in the intention-to-treat analyses. Waist circumference increased 0·5 (95 % CI 0·3, 0·7) cm (P< 0·001), but BMIz-score remained unaffected. Complete-case analyses and analyses adjusted for household educational level, pubertal status and physical activity confirmed the results. In conclusion, the school meals did not affect the MetS score in 8–11-year-olds, as small improvements in blood pressure, TAG concentrations and insulin resistance were counterbalanced by slight undesired effects on waist circumference and HDL-cholesterol concentrations.
Human Rights, Geostrategy, and EU Foreign Policy, 1989–2008
Authors: Kreutz Joakim
Published: October 2014

Is foreign policy influenced by humanitarian concerns, or are concepts such as human security merely rhetoric for traditional power politics? Using a multilevel modeling technique and a unique data set of military and economic European Union (EU) intervention 1989–2008, I find that military and economic interventions by the EU are conducted in response to humanitarian atrocities but that geostrategic concerns also influence EU action. While the EU consistently is more likely to act against countries with greater civilian victimization, the size of the effect is influenced by spatial considerations. The EU is most attentive to human rights violations in non-EU European states, followed by countries in sub-Saharan Africa, while it has been least active in Asia and the Americas.

Property law and practice in seventeenth-century London
Authors: DOOLITTLE IAN
Published: October 2014

This article uses the Decrees issued by the London Fire Court to explore two aspects of property law and practice in the 1660s. The first is the use of trusts and settlements. The Decrees suggest that at least for property owners these were more widespread than previously thought. The second theme concerns women. Fathers and husbands used their property carefully to make provision for their daughters and wives. More than that, women were clearly active participants in the property ‘market’, despite the legal restrictions imposed on them. The conclusions emphasize the importance of looking beyond legal rules.
EFFICIENT SORTING IN FRICTIONAL LABOR MARKETS WITH TWO-SIDED HETEROGENEITY
Authors: Merlino Luca Paolo
Published: October 2014

This paper studies how search externalities and wage bargaining distort vacancy creation and the allocation of workers to jobs in markets with two-sided heterogeneity. To do so, I propose a model of a frictional labor market where heterogeneous workers decide which job to look for and firms decide which technology to adopt. At equilibrium, there is perfect segmentation across sectors, which is determined by a unique threshold of workers' productivity. This threshold is inefficient because of participation and composition externalities. The Pigouvian tax scheme that decentralizes optimal sorting shows that these externalities have opposite signs. Furthermore, their relative strength depends on the distribution of workers' skills, so that when there are many (few) skilled workers, too many (few) high-technology jobs are created.

In this paper, a triple-band 1 × 2 and 1 × 4 microstrip patch antenna array for next-generation wireless and satellite-based applications are presented. The targeted frequency bands are 3.6, 5.2 and 6.7 GHz, respectively. Simple design procedures and optimization techniques are discussed to achieve better antenna performance. The antenna is designed and simulated using Agilent ADS Momentum using FR4 substrate (εr= 4.2 and h = 1.66 mm). The main patch of the antenna is designed for 3.6 GHz operation. A hybrid feed technique is used for antenna arrays with quarter-wave transformer-based network to match the impedance from the feed-point to the antenna to 50 Ω. The antenna is optimized to resonate at triple-bands by using two symmetrical slits. The single-element triple-band antenna is fabricated and characterized, and a comparison between the simulated and measured antenna is presented. The achieved simulated impedance bandwidths/gains for the 1 × 2 array are 1.67%/7.75, 1.06%/7.7, and 1.65%/9.4 dBi and for 1 × 4 array are 1.67%/10.2, 1.45%/8.2, and 1.05%/10 dBi for 3.6, 5.2, and 6.7 GHz bands, respectively, which are very practical. These antenna arrays can also be used for advanced antenna beam-steering systems.
‘Division of labour’ in response to host oxidative burst drives a fatal Cryptococcus gattii outbreak
Authors: Voelz Kerstin , Johnston Simon A. , Smith Leanne M. , Hall Rebecca A. , Idnurm Alexander , May Robin C.
Published: October 2014

Cryptococcus gattii is an emerging intracellular pathogen and the cause of the largest primary outbreak of a life-threatening fungal disease in a healthy population. Outbreak strains share a unique mitochondrial gene expression profile and an increased ability to tubularize their mitochondria within host macrophages. However, the underlying mechanism that causes this lineage of C. gattii to be virulent in immunocompetent individuals remains unexplained. Here we show that a subpopulation of intracellular C. gattii adopts a tubular mitochondrial morphology in response to host reactive oxygen species. These fungal cells then facilitate the rapid growth of neighbouring C. gattii cells with non-tubular mitochondria, allowing for effective establishment of the pathogen within a macrophage intracellular niche. Thus, host reactive oxygen species, an essential component of the innate immune response, act as major signalling molecules to trigger a ‘division of labour’ in the intracellular fungal population, leading to increased pathogenesis within this outbreak lineage.
Identification of microRNAs involved in acute rejection and spontaneous tolerance in murine hepatic allografts

Published: October 2014

Graft acceptance without the need for immunosuppressive drugs is the ultimate goal of transplantation therapy. In murine liver transplantation, allografts are accepted across major histocompatibility antigen complex barriers without the use of immunosuppressive drugs and constitute a suitable model for research on immunological rejection and tolerance. MicroRNA (miRNA) has been known to be involved in the immunological responses. In order to identify mRNAs in spontaneous liver allograft tolerance, miRNA expression in hepatic allografts was examined using this transplantation model. According to the graft pathological score and function, miR-146a, 15b, 223, 23a, 27a, 34a and 451 were upregulated compared with the expression observed in the syngeneic grafts. In contrast, miR-101a, 101b and 148a were downregulated. Our results demonstrated the alteration of miRNAs in the allografts and may indicate the role of miRNAs in the induction of tolerance after transplantation. Furthermore, our data suggest that monitoring the graft expression of novel miRNAs may allow clinicians to differentiate between rejection and tolerance. A better understanding of the tolerance inducing mechanism observed in murine hepatic allografts may provide a therapeutic strategy for attenuating allograft rejection.

A classical treatment of optical tunneling in plasmonic gaps: extending the quantum corrected model to practical situations
Authors: Esteban Rubén , Zugarramurdi Asier , Zhang Pu , Nordlander Peter , García-Vidal Francisco J. , Borisov Andrei G. , Aizpurua Javier
Published: October 2014

The optical response of plasmonic nanogaps is challenging to address when the separation between the two nanoparticles forming the gap is reduced to a few nanometers or even subnanometer distances. We have compared results of the plasmon response within different levels of approximation, and identified a classical local regime, a nonlocal regime and a quantum regime of interaction. For separations of a few Ångstroms, in the quantum regime, optical tunneling can occur, strongly modifying the optics of the nanogap. We have considered a classical effective model, so called Quantum Corrected Model (QCM), that has been introduced to correctly describe the main features of optical transport in plasmonic nanogaps. The basics of this model are explained in detail, and its implementation is extended to include nonlocal effects and address practical situations involving different materials and temperatures of operation.

The angiotensin type 2 receptor (AT2R) and the receptor Mas are components of the protective arms of the renin–angiotensin system (RAS), i.e. they both mediate tissue protective and regenerative actions. The spectrum of actions of these two receptors and their signalling mechanisms display striking similarities. Moreover, in some instances, antagonists for one receptor are able to inhibit the action of agonists for the respective other receptor. These observations suggest that there may be a functional or even physical interaction of both receptors. This article discusses potential mechanisms underlying the phenomenon of blockade of angiotensin-(1–7) [Ang-(1–7)] actions by AT2R antagonists and vice versa. Such mechanisms may comprise dimerization of the receptors or dimerization-independent mechanisms such as lack of specificity of the receptor ligands used in the experiments or involvement of the Ang-(1–7) metabolite alamandine and its receptor MrgD in the observed effects. We conclude that evidence for a functional interaction of both receptors is strong, but that such an interaction may be species- and/or tissue-specific and that elucidation of the precise nature of the interaction is only at the very beginning.

Modeling Evidence-Based Practice for Graduate Clinicians: Perspectives from Off-Site Clinical Supervisors in Medical Settings
Authors: Hart Sharon B. , Kleinhans Kelly A.
Published: October 2014

A fundamental aspect of graduate education in speech-language pathology is facilitating clinical competence. Teaching clinical decision-making within an evidence-based practice framework is necessary during both on-site and off-site clinical experiences. In this article the authors present the results of semi-structured interviews with off-site supervisors in medical settings. Interview questions addressed aspects of evidence-based practice (EBP) that are discussed or modeled for students. Supervisors also weighed the importance of each EBP element in their practice. Clinical expertise was given slightly more weight as compared to external scientific evidence and client/patient/caregiver perspective elements. However, individual responses were highly variable across participants. Suggestions for ensuring continued EBP instruction during off-site clinical placements is discussed.
Analytical estimation of the correlation dimension of integer lattices
Authors: Lacasa Lucas , Gómez-Gardeñes Jesús
Published: October 2014

Recently [L. Lacasa and J. Gómez-Gardeñes, Phys. Rev. Lett. 110, 168703 (2013)], a fractal dimension has been proposed to characterize the geometric structure of networks. This measure is an extension to graphs of the so called correlation dimension, originally proposed by Grassberger and Procaccia to describe the geometry of strange attractors in dissipative chaotic systems. The calculation of the correlation dimension of a graph is based on the local information retrieved from a random walker navigating the network. In this contribution, we study such quantity for some limiting synthetic spatial networks and obtain analytical results on agreement with the previously reported numerics. In particular, we show that up to first order, the correlation dimension β of integer lattices ℤd coincides with the Haussdorf dimension of their coarsely equivalent Euclidean spaces, β = d.
Self-trapping transition for a nonlinear impurity within a linear chain
Authors: Yue Haitian , Molina Mario I. , Kevrekidis Panayotis G. , Karachalios Nikos I.
Published: October 2014

In the present work, we revisit the issue of the self-trapping dynamical transition at a nonlinear impurity embedded in an otherwise linear lattice. For our Schrödinger chain example, we present rigorous arguments that establish necessary conditions and corresponding parametric bounds for the transition between linear decay and nonlinear persistence of a defect mode. The proofs combine a contraction mapping approach applied to the fully dynamical problem in the case of a 3D-lattice, together with variational arguments for the derivation of parametric bounds for the creation of stationary states associated with the expected fate of the self-trapping dynamical transition. The results are relevant for both power law nonlinearities and saturable ones. The analytical results are corroborated by numerical computations. The latter are performed for cases of different dimension.

Published: October 2014

The valence band (VB) structures of face-centered-cubic Ag-Rh alloy nanoparticles (NPs), which are known to have excellent hydrogen-storage properties, were investigated using bulk-sensitive hard x-ray photoelectron spectroscopy. The observed VB spectra profiles of the Ag-Rh alloy NPs do not resemble simple linear combinations of the VB spectra of Ag and Rh NPs. The observed VB hybridization was qualitatively reproduced via a first-principles calculation. The electronic structure of the Ag0.5Rh0.5 alloy NPs near the Fermi edge was strikingly similar to that of Pd NPs, whose superior hydrogen-storage properties are well known.

Four-array system of soft X-ray diagnostics was installed on KSTAR tokamak. Each array has 32 viewing chords of two photo-diode array detectors with spatial resolution of 2 cm. To estimate signals from the soft X-ray radiation power, typical ne, Te, and argon impurity line radiation profiles in KSTAR are chosen. The photo-diodes were absolutely calibrated as a function of the incident photon energy in 2–40 keV range with a portable X-ray tube. Two-dimensional Te image properties by multi-energy method were simulated and visualized with six combinations of beryllium filter sets within the dynamic range of signal ratio.
A scanning, all-fiber Sagnac interferometer for high resolution magneto-optic measurements at 820 nm
Authors: Fried Alexander , Fejer Martin , Kapitulnik Aharon
Published: October 2014

The Sagnac Interferometer has historically been used for detecting non-reciprocal phenomena, such as rotation. We demonstrate an apparatus in which this technique is employed for high resolution measurements of the Magneto-Optical Polar Kerr effect—a direct indicator of magnetism. Previous designs have incorporated free-space components which are bulky and difficult to align. We improve upon this technique by using all fiber-optic coupled components and demonstrate operation at a new wavelength, 820 nm, with which we can achieve better than 1 μrad resolution. Mounting the system on a piezo-electric scanner allows us to acquire diffraction limited images with 1.5 μm spatial resolution. We also provide extensive discussion on the details and of the Sagnac Interferometer's construction.
Sputtering of cobalt film with perpendicular magnetic anisotropy on disorder-free graphene
Authors: Jamali Mahdi , Lv Yang , Zhao Zhengyang , Wang Jian-Ping
Published: October 2014

Growth of thin cobalt film with perpendicular magnetic anisotropy has been investigated on pristine graphene for spin logic and memory applications. By reduction of the kinetic energy of the sputtered atoms using indirect sputtered deposition, deposition induced defects in the graphene layer have been controlled. Cobalt film on graphene with perpendicular magnetic anisotropy has been developed. Raman spectroscopy of the graphene surface shows very little disorder induced in the graphene by the sputtering process. In addition, upon increasing the cobalt film thickness, the disorder density increases on the graphene and saturates for thicknesses of Co layers above 1 nm. The AFM image indicates a surface roughness of about 0.86 nm. In addition, the deposited film forms a granular structure with a grain size of about 40 nm.

Published: October 2014

Through the installation of electron gun and photon detector, an in-situ photoemission and damage-free sputtering integrated analysis system is completely constructed. Therefore, this system enables to accurately characterize the energy level alignments including unoccupied/occupied molecular orbital (LUMO/HOMO) levels at interface region of organic semiconductor/electrode according to depth position. Based on Ultraviolet Photoemission Spectroscopy (UPS), Inverse Photoemission Spectroscopy (IPES), and reflective electron energy loss spectroscopy, the occupied/unoccupied state of in-situ deposited Tris[4-(carbazol-9-yl)phenyl]amine (TCTA) organic semiconductors on Au (ELUMO: 2.51 eV and EHOMO: 1.35 eV) and Ti (ELUMO: 2.19 eV and EHOMO: 1.69 eV) electrodes are investigated, and the variation of energy level alignments according to work function of electrode (Au: 4.81 eV and Ti: 4.19 eV) is clearly verified. Subsequently, under the same analysis condition, the unoccupied/occupied states at bulk region of TCTA/Au structures are characterized using different Ar gas cluster ion beam (Ar GCIB) and Ar ion sputtering processes, respectively. While the Ar ion sputtering process critically distorts both occupied and unoccupied states in UPS/IPES spectra, the Ar GCIB sputtering process does not give rise to damage on them. Therefore, we clearly confirm that the in-situ photoemission spectroscopy in combination with Ar GCIB sputtering allows of investigating accurate energy level alignments at bulk/interface region as well as surface region of organic semiconductor/electrode structure.
Potential energy curves for the ground and low-lying excited states of CuAg
Authors: Alizadeh Davood , Jamshidi Zahra , Shayesteh Alireza
Published: October 2014

The ground and low-lying excited states of heteronuclear diatomic CuAg are examined by multi-reference configuration interaction (MRCI) method. Relativistic effects were treated and probed in two steps. Scalar terms were considered using the spin-free DKH Hamiltonian as a priori and spin-orbit coupling was calculated perturbatively via the spin-orbit terms of the Breit-Pauli Hamiltonian based on MRCI wavefunctions. Potential energy curves of the spin-free states and their corresponding Ω components correlating with the separated atom limits 2S(Cu) + 2S(Ag) and 2D(Cu) + 2S(Ag) are obtained. The results are in fine agreement with the experimental measurements and tentative conclusions for the ion-pair B0+ state are confirmed by our theoretical calculations. Illustrative results are presented to reveal the relative importance and magnitude of the scalar and spin-orbit effects on the spectroscopic properties of this molecule. Time dependent density functional theory calculations, using the LDA, BLYP, B3LYP, and SAOP functionals have been carried out for CuAg and the accuracy of TD-DFT has been compared with ab initio results.
Non-Born-Oppenheimer calculations of the pure vibrational spectrum of T2 including relativistic corrections
Authors: Stanke Monika , Adamowicz Ludwik
Published: October 2014

We report very accurate calculations of the complete pure vibrational spectrum of the T2 molecule with an approach where the Born-Oppenheimer (BO) approximation is not assumed. As the considered states correspond to the zero total angular momentum, their non-BO wave functions are spherically symmetric and are expanded in terms of all-particle, one-center, spherically symmetric explicitly correlated Gaussian functions multiplied by even nonnegative powers of the internuclear distance. The nonrelativistic energies of the states obtained in the non-BO calculations are corrected for the relativistic effects of the order of α2 (where α is the fine structure constant) calculated as expectation values of the operators representing these effects.
Complete active space second order perturbation theory (CASPT2) study of N(2D) + H2O reaction paths on D1 and D potential energy surfaces: Direct and roaming pathways
Authors: Isegawa Miho , Liu Fengyi , Maeda Satoshi , Morokuma Keiji
Published: October 2014

We report reaction paths starting from N(2D) + H2O for doublet spin states, D0 and D1. The potential energy surfaces are explored in an automated fashion using the global reaction route mapping strategy. The critical points and reaction paths have been fully optimized at the complete active space second order perturbation theory level taking all valence electrons in the active space. In addition to direct dissociation pathways that would be dominant, three roaming processes, two roaming dissociation, and one roaming isomerization: (1) H2ON → H–O(H)N → H–HON → NO(2Π) + H2, (2) cis-HNOH → HNO–H → H–HNO → NO + H2, (3) H2NO → H–HNO → HNO–H → trans-HNOH, are confirmed on the D0 surface.
