A quantitative Carleman estimate for second-order elliptic operators
Authors: Nakić Ivica , Rose Christian , Tautenhahn Martin 
Published: December 2018

AbstractWe prove a Carleman estimate for elliptic second-order partial differential expressions with Lipschitz continuous coefficients. The Carleman estimate is valid for any complex-valued function u ∈ W2,2 with support in a punctured ball of arbitrary radius. The novelty of this Carleman estimate is that we establish an explicit dependence on the Lipschitz and ellipticity constants, the dimension of the space and the radius of the ball. In particular, we provide a uniform and quantitative bound on the weight function for a class of elliptic operators given explicitly in terms of ellipticity and Lipschitz constant.
Bifurcation and standing wave solutions for a quasilinear Schrödinger equation
Authors: Dai Guowei 
Published: December 2018

AbstractWe use bifurcation and topological methods to investigate the existence/nonexistence and the multiplicity of positive solutions of the following quasilinear Schrödinger equation$$\left\{ {\matrix{ {-\Delta u-\kappa \Delta \left( {u^2} \right)u = \beta u-\lambda \Phi \left( {u^2} \right)u{\mkern 1mu} {\mkern 1mu} } \hfill &amp; {{\rm in}\;\Omega ,} \hfill \cr {u = 0} \hfill &amp; {{\rm on}\;\partial \Omega } \hfill \cr } } \right.$$involving sublinear/linear/superlinear nonlinearities at zero or infinity with/without signum condition. In particular, we study the changes in the structure of positive solution withκas the varying parameter.
Compulsory Voting: A Defence
Authors: Umbers Lachlan M 
Published: December 2018

AbstractTurnout is in decline in established democracies around the world. Where, in the mid-1800s, 70–80 percent of eligible voters regularly participated in US Presidential elections, turnout has averaged just 53.7 percent since 1972. Average turnout in general elections in the UK has fallen from 76.6 percent during the period 1945–92, to 64.7 percent since 1997. Average turnout in Canadian federal elections has fallen from 74.5 percent during the period 1940–79, to 62.5 percent since 2000. For most democrats, these numbers are a cause for alarm. Compulsory voting is amongst the most effective means of raising turnout. However, compulsory voting is also controversial. Most of us think that coercion may only be employed against the citizenry if it is backed by a justification of the right kind. Opponents of compulsory voting charge that no such justification is available. This article resists this line of argument in two ways. First, I offer an argument from free-riding which, though gestured towards by others, and widely criticized, has yet to be defended in any depth. Second, I consider a range of objections to compulsory voting as such, arguing that none succeeds.
Are Transfer-Dependent Governments More Creditworthy? Reassessing the Fiscal Federal Foundations of Subnational Default Risk
Authors: Hanniman Kyle 
Published: December 2018

AbstractMany fiscal federal scholars argue, often implicitly, that transfer dependence generally bolsters subnational creditworthiness by signalling a higher likelihood of national bailouts for distressed governments. This article argues that dependence fails to bestow general benefits on local borrowers because it suggests an inability to generate additional revenues in the event of fiscal distress, and because this inability does not, contrary to the expectations of many, necessarily translate into higher bailout expectations. Ultimately it is the nature, not the level, of transfers that affects local creditworthiness, whether through bailout or non-bailout channels. Stable and predictable payments, including robust equalization systems, support local creditworthiness, while volatile and unpredictable transfers do not. The article supports these arguments with a review of documents issued by the major international credit rating agencies and cross-national statistical analyses of bailout probabilities and standalone credit ratings issued by Moody’s Investors Service. It also discusses the implications of the findings for work on the fiscal discipline of subnational governments.

AbstractWe present a new set of clay mineral and grain-size data for the siliciclastic sediment fraction from International Ocean Discovery Program (IODP) Site U1456 located in the eastern Arabian Sea to reconstruct the variabilities in the continental erosion and weathering intensity in the western Himalaya, elucidate the sediment source-to-sink processes and discuss the potential controls underlying these changes since 3.7 Ma. The clay minerals mainly consist of smectite (0–90%, average 44%) and illite (3–90%, average 44%), with chlorite (1–26%, average 7%) and kaolinite (0–19%, average 5%) as minor components. The compositional variations in the clay minerals at IODP Site U1456 suggest four phases of sediment provenance: the Indus River (phase 1, 3.7–3.2 Ma), the Indus River and Deccan Traps (phase 2, 3.2–2.6 Ma), the Indus River (phase 3, 2.6–1.2 Ma) and the Indus River and Deccan Traps (phase 4, 1.2–0 Ma). These provenance changes since 3.7 Ma can be correlated with variations in the Indian summer monsoon intensity. The siliciclastic sediments in the eastern Arabian Sea were mainly derived from the Indus River when the Indian summer monsoon was generally weak. In contrast, when the Indian summer monsoon intensified, the siliciclastic sediment supply from the Deccan Traps increased. In particular, this study shows that the smectite/(illite+chlorite) ratio is a sensitive tool for reconstructing the history of the variation in the Indian summer monsoon intensity over the continents surrounding the Arabian Sea since 3.7 Ma.
Estimating geographic variations in the determinants of attitude towards the practice of female genital mutilation in Nigeria
Authors: Gayawan Ezra , Lateef Rukayat Salewa 
Published: December 2018

AbstractFemale genital mutilation (FGM) has persisted in Nigeria despite the very harmful effects on its victims. Massive inequality in the demographic and socioeconomic status of the Nigerian populace, coupled with marked differences in cultural values, have led to lopsided patterns of most health indicators based on the geographical location. The risk factors of health indicators are equally expected to vary according to location. This study aimed to explain the spatial variations in the risk factors for female cutting in Nigeria. Data were from the geo-referenced 2013 Nigeria Demographic and Health Survey. The objective was to estimate the spatially varying relationships of the factors influencing women’s attitude towards female cutting in Nigeria and to identify how the variables exact influence across the states using geographically weighted logistic regression analysis – a technique that allows for spatially varying relationships among variables to be established. The results showed that women’s higher educational level and higher household wealth lowered the desire for continuation of FGM everywhere in the country, but the effects of most other variables varied in direction, strength and magnitude. The findings suggest the use of local approaches to address the factors that encourage the continuation of female cutting in Nigeria.

Published: December 2018

AbstractDuring the summer of 2013 two scientific surveys (northern, at the beginning of July and southern, at the end of July) were carried out along the eastern Adriatic Sea. In these surveys, ichthyoplankton samples of anchovy (Engraulis encrasicolus, Linnaeus 1758) eggs and larvae were collected. In the whole investigated area, egg and larvae abundance varied from 2.61 to 1040.24 eggs m−2 (geometric mean ± CL: 25.43 ± 1.48 eggs m−2) and 2.73 larvae m−2 to 611.14 larvae m−2 (geometric mean ± CL: 17.07 ± 1.41 larvae m−2), respectively. Higher abundance of anchovy early life stages was noted in the northern part of the investigated area. The length of the collected specimens lay within the range of 2.39–3.68 mm and those individuals were less than 12 h old. Analysis of spatial and temporal distribution of collected anchovy early life stages indicated their higher abundance in areas of upwelling (four areas were distinguished on the eastern Adriatic side). Larger and older specimens were collected at the beginning of July in the northern part of Adriatic indicating that the anchovy population in the Adriatic tends to shift among its spawning centres in this area. In general, anchovy eggs were accompanied by its larvae (r = 0.453, P < 0.05), while statistically significant negative correlation was obtained between egg abundance and temperature (r = −0.380, P < 0.05) as well as sea depth (r = −0.321, P < 0.05).
Similarity and the trustworthiness of distributive judgements
Authors: Voorhoeve Alex , Stefánsson Arnaldur , Wallace Brian 
Published: December 2018

AbstractWhen people must either save a greater number of people from a smaller harm or a smaller number from a greater harm, do their choices reflect a reasonable moral outlook? We pursue this question with the help of an experiment. In our experiment, two-fifths of subjects employ a similarity heuristic. When alternatives appear dissimilar in terms of the number saved but similar in terms of the magnitude of harm prevented, this heuristic mandates saving the greater number. In our experiment, this leads to choices that are inconsistent with all standard theories of justice. We argue that this demonstrates the untrustworthiness of distributive judgements in cases that elicit similarity-based choice.
THE DEGREE PROFILE AND GINI INDEX OF RANDOM CATERPILLAR TREES
Authors: Zhang Panpan , Dey Dipak K. 
Published: December 2018

AbstractIn this paper, we investigate the degree profile and Gini index of random caterpillar trees (RCTs). We consider RCTs which evolve in two different manners: uniform and nonuniform. The degrees of the vertices on the central path (i.e., the degree profile) of a uniform RCT follows a multinomial distribution. For nonuniform RCTs, we focus on those growing in the fashion of preferential attachment. We develop methods based on stochastic recurrences to compute the exact expectations and the dispersion matrix of the degree variables. A generalized Pólya urn model is exploited to determine the exact joint distribution of these degree variables. We apply the methods from combinatorics to prove that the asymptotic distribution is Dirichlet. In addition, we propose a new type of Gini index to quantitatively distinguish the evolutionary characteristics of the two classes of RCTs. We present the results via several numerical experiments.
Civilizational Exceptions: Ottoman Law and Governance in Late Ottoman Palestine
Authors: Amara Ahmad 
Published: December 2018

AbstractThis article examines the Ottoman extension of rule and jurisdiction to the Beersheba frontier of southern Palestine. As part of itsTanzimatreform policies, the Ottoman administration founded the new town and sub-district of Beersheba in 1900, and sought to implement a legal reform. Deviating from the formal law that requires the founding of a civil-nizamiye court, the Ottoman instituted a form of legal exception and authorized the local administrative council to sit as a judicial forum and for its Bedouin Shaykh members to serve as judges. Studies of Ottoman Beersheba have typically focused on Bedouin autonomy and tribal law. The few studies that discussed the judicial order, have mistakenly assumed the Ottoman institution of a “tribal court,” and its persistence thereafter. Interestingly, what began as a simple grant of legal exception, justified by civilizational discourses of ignorance and savagery, grew into a judicial complexity. Very soon jurisdictional tensions arose, integrating questions across various webs of legal orders, jurisdictions, and political networks that shaped the reform in Beersheba and beyond. In following various legal disputes from Beersheba to Gaza, Jerusalem, and Istanbul, the article challenges some of the prevailing research categories, dichotomies, and approaches in the study of Ottoman legal history and tribal societies, including the concept of ‘legal pluralism.’
Performing the rule of law in international organizations: Ibrahim Shihata and the World Bank’s turn to governance reform
Authors: Van Den Meerssche Dimitri 
Published: December 2018

AbstractIn recent years, the academic field of international institutional law has taken a clear ‘constitutional’ turn. In this normative endeavour, liberal ‘rule of law’ ideals are being reinvigorated, translated and projected onto international organizations. This article trades this well-trodden path for a socio-legal inquiry into how the ‘rule of law’ is produced, practiced and performed in the everyday political and operational life of one specific international organization (the World Bank) during one contentious historical episode. To grasp what it means for ‘law to rule’, I argue, we need to expand our archives to the daily praxis of legality: the actors that embody it; the consciousness that drives it; the politics that rely on it; and the fragile institutional balances that give it meaning. Grounded in this pragmatist perspective, I retrace the intervention of legal expertise during the Bank’s turn to state reform in the wake of the Cold War. Descending from principles to practices, from norms to acts, from abstract heights to situated performances, the article not only strives for an enhanced understanding of the ‘rule of law’ within the World Bank, but also aims at a critical methodological intervention in the field of international institutional law.
A review: Percutaneous pulmonary artery stenosis therapy: state-of-the-art and look to the future
Authors: Patel Anuj B. , Ratnayaka Kanishka , Bergersen Lisa 
Published: December 2018

AbstractStenosis, or narrowing, of the branches of the pulmonary artery is a type of CHD that, if left untreated, may lead to significant complications. Ideally, interventions to treat stenosis occur before significant complications or long-term sequelae take place, often within the first 2 years of life. Treatment depends on specifics of the condition, the presence of other malformations, and age of the child. Research and recent innovation to address these shortcomings have provided physicians with safer and more effective methods of treatment. This has further continued to push the ceiling of pulmonary arterial stenosis treatment available for patients. Despite continuous advancement in angioplasty – such as conventional and cutting balloon – and stenting, each treatment method is not without its unique limitations. New technological developments such as bioresorbable stents can accommodate patient growth and pulmonary artery stenosis treatment. As more than a decade has passed since the review by Bergersen and Lock, this article aims to provide a contemporary summary and investigation into the effectiveness of various therapeutic tools currently available, such as bare metal stents and potential innovations including bioresorbable stents.

AbstractObjectiveObesity and hyperglycaemia contribute to the atherosclerotic process in part through oxidative modifications to lipoprotein particles. The present study aimed to evaluate the effects of a lifestyle intervention on markers of oxidized lipoproteins in obese Latino adolescents with prediabetes.DesignPre–post design.SettingParticipants were enrolled into a 12-week lifestyle intervention. Measurements pre- and post-intervention included anthropometrics and body composition, lipid panel, oxidized LDL (oxLDL), oxidized HDL (oxHDL), intake of fresh fruits and vegetables, and cardiorespiratory fitness.ParticipantsThirty-five obese Latino adolescents (seventeen females, eighteen males; mean age 15·5 (sd1·0) years; mean BMI percentile 98·5 (sd1·2)) with prediabetes.ResultsIntervention participation resulted in significant reductions in weight (−1·2 %,P= 0·042), BMI and BMI percentile (−2·0 and −0·4 %, respectively,P< 0·001), body fat (−7·0 %,P= 0·025), TAG (−11·8 %,P= 0·032), total cholesterol (−5·0 %,P= 0·002), VLDL-cholesterol (−12·5 %,P= 0·029), and non-HDL-cholesterol (−6·7 %,P= 0·007). Additionally, fitness (6·4 %,P< 0·001) and intake of fruits and vegetables (42·4 %,P= 0·025) increased significantly. OxLDL decreased significantly after the intervention (51·0 (sd14·0)v. 48·7 (sd12·8) U/l,P= 0·022), while oxHDL trended towards a significant increase (395·2 (sd94·6)v. 416·1 (sd98·4) ng/ml,P= 0·056).ConclusionsThese data support the utility of lifestyle intervention to improve the atherogenic phenotype of Latino adolescents who are at high risk for developing premature CVD and type 2 diabetes.
Microstructural, Mineralogical and Petrographical Characteristics of the Medieval Ceramics from the Studenica Monastery (UNESCO World Heritage Site): Implications on the Pottery Technology and Provenance of The Raw Material
Authors: Šarić Kristina , Bikić Vesna , Erić Suzana 
Published: December 2018

AbstractOn the basis of optical microscopy, scanning electron microscopy with energy-dispersive spectrometry and X-ray powder diffraction analyses, we present detailed mineralogical and petrographical characteristics of 63 samples of cooking and tablewares, which originate from two Medieval horizons (S1 and S2) in the Studenica Monastery, as well as of three samples of clays regarded as possible pottery raw material. The composition of the ceramic matrix is compatible with the composition of local clay and clasts that reflect the geology of the Studenica’s surroundings. This indicates that almost all studied vessels are unequivocally made locally. However, four wares may represent imports because they show similarities with Byzantine sgraffito wares, and ceramics from the Peloponnese (13th century). In terms of technological and morphological characteristics, the studied pottery collection represents a standardized production. Firing temperatures, estimated according to the level of matrix crystallinity, mineral reactions, and the mode of the appearance of fracture surfaces, indicate that most of cooking wares were fired at 600–700°C. All glazed wares, including tablewares and cooking pots from both S1 and S2, were fired at minimum 800–900°C. Along with technological and morphological standardization the characteristics of the studied collection show knowledge of traditional skills as well as trends within the Byzantine artistic craft circle.
INEFFABILITY AND REVENGE
Authors: SCAMBLER CHRIS 
Published: December 2018

AbstractIn recent work Philip Welch has proven the existence of ‘ineffable liars’ for Hartry Field’s theory of truth. These are offered as liar-like sentences that escape classification in Field’s transfinite hierarchy of determinateness operators. In this article I present a slightly more general characterization of the ineffability phenomenon, and discuss its philosophical significance. I show the ineffable sentences to be less ‘liar-like’ than they appear in Welch’s presentation. I also point to some open technical problems whose resolution would greatly clarify the philosophical issues raised by the ineffability phenomenon.
Sensitivity Kernels of PP Precursor Traveltimes and Their Limitations for Imaging Topography of Discontinuities
Authors: Koroni Maria , Paulssen Hanneke , Trampert Jeannot 
Published: December 2018

AbstractWe analyze the sensitivity of PP precursor traveltimes that are often used to infer lateral variation in the depths of the 410‐ and 660‐km discontinuities in the mantle. Previous results were inconclusive due to complex wave phenomena, such as multiple energy conversions and focusing/defocusing, that hamper their interpretation. Using spectral‐element synthetics and Fréchet derivatives calculated with adjoint methods, we compute sensitivity kernels for volumetric and boundary parameters in a 1‐D model for representative epicentral distances of past studies, and a dominant period of 11–25 s. Our results indicate that the boundary sensitivity of PP precursors is low and that these phases are not coherently seen in exact synthetics. Our most important finding is the strong sensitivity to both shear and compressional wave speeds, indicating that wave interference and wave conversions are dominant. The PP precursor traveltimes appear more sensitive to structural parameters, that is, compressional and shear wave speed, than to the boundaries; therefore, they are unlikely sources for valuable insight into discontinuity topography.

AbstractThe Lyman Alpha Mapping Project has detected five discrete low‐albedo anomalies in Lyman‐α (Ly‐α; 121.6 nm) nighttime reflectance maps. These anomalies reside on the nearside of the Moon within the southeastern Oceanus Procellarum and northwestern Mare Nubium, coincident with regions that have been observed to be photometrically anomalous at visible wavelengths. Some of the spectral properties of these regions within near ultraviolet (NUV) to visible (VIS) wavelengths are consistent with lunar swirls, and they have been reported as “probable swirls” in at least one of these studies. However, while these regions have low Ly‐α normal albedo values relative to nearby highlands regions and are consistent with Ly‐α albedo observations of other swirls, they do not spectrally redden at wavelengths >160 nm as other swirls have been shown to do and they are not associated with regions of higher magnetic intensity. Interestingly, while these anomalies are not easily discerned in NUV single‐band images, the anomalies can be discerned in NUV color ratio composites of the Lunar Reconnaissance Orbiter Camera Wide‐Angle Camera. At least one anomaly observed in the far ultraviolet is not easily observed in the NUV. Additional analyses of their thermal emission Christiansen Feature values, empirically corrected for maturity, suggest that regolith maturity is what differentiates them from their surroundings. While these anomalies may not be swirls, they may represent an “endmember” to swirls minus the influence magnetic materials, which have been hypothesized to provide solar wind shielding. If true, they may provide additional insight into the generation of lunar swirls.
