description: In the aftermath of three years of armed conflict involving the Salafi jihadist militant group known as the Islamic State of Iraq and the Levant (ISIL), thousands of Iraqi children are undocumented and at risk of statelessness because they were born in ISIL captivity. These children are the products of both ISIL-perpetrated sexual violence as well as consensual intercourse with members of the jihadist group. Whether or not they are the products of genderbased violence, the children born in ISIL captivity lack valid civil status registration and documentation, rendering it difficult if not impossible for them to prove their nationality and citizenship—putting them at an increased risk of statelessness—and leaving them unable to access to healthcare, housing, education, and other basic services. A majority of the media coverage and limited scholarly research on the children born of the ISIL conflict in Iraq focuses exclusively on children born of ISIL-perpetrated sexual violence. This paper aims to close the gap in existing academic literature by investigating the social, economic, and legal challenges for all children born of the ISIL conflict in Iraq, regardless of whether or not such children are the products of gender-based violence or consensual marriage and intercourse. Because birth registration is a basic right necessary for establishing nationality and citizenship, and is often crucial for the realization of other human rights, this paper focuses on the lack of access to civil status registration as one of the most urgent concerns for virtually all children born of the ISIL conflict in Iraq. To investigate this issue, this study applies a human rights framework to the following research question: What are the risks and consequences for the children born of the ISIL conflict in Iraq who lack birth registration and civil status documentation?

description: We derive a spin diffusion equation for a spin-orbit coupled two-dimensional electron gas including the Hartree-Fock field resulting from first order electron-electron interactions. We find that the lifetime of the persistent spin helix, which emerges for equal linear Rashba and Dresselhaus spin-orbit interactions, can be enhanced considerably for large initial spin polarizations due to the Hartree-Fock field. The reason is a reduction of the symmetry-breaking cubic Dresselhaus scattering rate by the Hartree-Fock field. Also higher harmonics are generated and the polarization of the persistent spin helix rotates out of the (Sy,Sz) plane acquiring a finite Sx component. This effect becomes more pronounced when the cubic Dresselhaus spin-orbit interaction is large.

description: Many predatory insects that prey on herbivores also feed on the plant, but it is unknown whether plants affect the performance of herbivores by responding to this phytophagy with defence induction. We investigate whether the prior presence of the omnivorous predator Macrolophus pygmaeus (Rambur) on tomato plants affects plant resistance against two different herbivore species. Besides plant-mediated effects of M. pygmaeus on herbivore performance, we examined whether a plant defence trait that is known to be inducible by herbivory, proteinase inhibitors (PI), may also be activated in response to the interactions of this predator with the tomato plant. We show that exposing tomato plants to the omnivorous predator M. pygmaeus reduced performance of a subsequently infesting herbivore, the two-spotted spider mite Tetranychus urticae Koch, but not of the greenhouse whitefly Trialeurodes vaporariorum (Westwood). The spider-mite infested tomato plants experience a lower herbivore load, i.e., number of eggs deposited and individuals present, when previously exposed to the zoophytophagous predator. This effect is not restricted to the exposed leaf and persists on exposed plants for at least two weeks after the removal of the predators. The decreased performance of spider mites as a result of prior exposure of the plant to M. pygmaeus is accompanied by a locally and systemically increased accumulation of transcripts and activity of proteinase inhibitors that are known to be involved in plant defence. Our results demonstrate that zoophytophagous predators can induce plant defence responses and reduce herbivore performance. Hence, the suppression of populations of certain herbivores via consumption may be strengthened by the induction of plant defences by zoophytophagous predators.

description: We re-examine questions concerning the contribution of the three-gluon Weinberg operator to the electric dipole moment of the neutron, and provide several QCD sum rule-based arguments that the result is smaller than - but nevertheless consistent with - estimates which invoke naive dimensional analysis. We also point out a regime of the MSSM parameter space with light gluinos for which this operator provides the dominant contribution to the neutron electric dipole moment due to enhancement via the dimension five color electric dipole moment of the gluino.

description: Our children are our future; if this is so, why should they be excluded from important
scientific studies which could be aided by their participation? The role of children in society has
spanned the full spectrum, ranging from helpless individuals to “little adults,” but what exactly
should their role in research participation be? In the past, they have been taken advantage of,
used in research that exposed them to unnecessary risks. Prior to 1966, children were frequently
research subjects because they were convenient and cheap in the sense that they were non-valued
or viewed as expendable commodities (Ross, 2006). The research of the time unfortunately
reflected this devalued vision of children.

description: The international community was caught by surprise on 5 June 2017 when Saudi Arabia, the United Arab Emirates (UAE), Bahrain and Egypt severed diplomatic ties with Qatar, accusing it of destabilizing the region. More than one year after this diplomatic rift, several questions remain unaddressed. This study focuses on the regional business costs of the year-long blockade on Qatar. We split the sample to compare the stock market performances of Qatar and its Middle Eastern neighbors before and after the Saudi-led Qatar boycott. We focus our attention on the conditional volatility process of stock market returns and risks related to financial interconnectedness. We show that the Gulf crisis had the most adverse impact on Qatar together with Saudi Arabia and the UAE. Although not to the same degree as these three countries, Bahrain and Egypt were also harmfully affected. But shocks to the volatility process tend to have short-lasting effects. Moreover, the total volatility spillovers to and from others increase but moderately after the blockade. Overall, the quartet lobbying efforts did not achieve the intended result. Our findings underscore Qatar's economic vulnerability but also the successful resilience strategy of this tiny state. The coordinated diplomatic efforts of Qatar have been able to fight the economic and political embargo.

description: The geometry of graded principal bundles is discussed in the framework of graded manifold theory of Kostant-Berezin-Leites. In particular, we prove that a graded principal bundle is globally trivial if and only if it admits a global graded section and, further, that the sheaf of vertical derivations on such a bundle coincides with the graded distribution induced by the action of the structure graded Lie group. This result leads to a natural definition of the graded connection in terms of graded distributions; its relation with Lie superalgebra-valued graded differential forms is also exhibited. Finally, we define the curvature for the graded connection; we prove that the curvature controls the involutivity of the horizontal graded distribution corresponding to the graded connection.

Je rapporte à cette espèce tous les spécimens dont le rapport longueur des élytres sur longueur des ailes (E/A) est inférieur à 3, qui correspondent aux captures anciennes de Kéoulenta, Yalanzou, Séringbara et Pierré Richaud (900 m) signalées par Chopard (1958: 145), ainsi qu’à celles des savanes de Ziéla et Gouéla signalées par Dirsh (1963: 216). D’autres captures ont été faites plus récemment en divers endroits et au total l’espèce a été récoltée un peu partout sur le piedmont et les basses pentes, surtout en savane (Kéoulenta, Ziéla, Gouéla, Gbakoré, plateau de Zouguépo entre 750 et 800 m, montée vers le Pierré Richaud à 900 m depuis Ziéla), mais aussi en prairie sur cuirasse près de Gbakoré, en forêt-galerie du Zougué vers 700 m, et même une femelle a été trouvée à 1200 m entre le Gouan et le Zougué (17.III.1981, C. Girard et M. Lamotte); milieux non précisés pour Yalanzou, Sérengbara et Niomouya.
Au total des jeunes des deux derniers stades ont été trouvés d’octobre à février, et des adultes de décembre à mars, ce qui implique une seule génération par an avec adultes en saison sèche. Le rapport E/A a été trouvé variable de 1,75 à 2,20 pour les mâles et de 2,05 à 2,90 pour les femelles, les valeurs les plus faibles concernant 1 mâle de Kéoulenta et 1 femelle du plateau de Zouguépo, les plus fortes 1 mâle de Kéoulenta également et 1 femelle de Sérengbara; la capture la plus élevée, 1 femelle de la prairie à 1200 m, a un rapport de 2,85 tandis que dans la savane à 900 m de la montée du Pierré Richaud, 2 mâles ont été trouvés avec 2,80 et 2,10, et une femelle avec 2,50. Les ailes sont presque hyalines ou diversement obscurcies.
Les rapports E/A trouvés au Nimba sont en bon accord avec ceux déduits de la littérature pour les spécimens du Togo d’où l’espèce a été décrite: d’après les données de Karsch (1893) et de Sjöstedt (1923) pour ce pays, on trouve en effet de 1,80 à 2,15 pour les mâles et de 2,50 à 3,00 pour les femelles, valeurs bien plus faibles que celles (3 à 4) dont fait état Dirsh (1966), qui a dû prendre en considération un matériel différent, pas forcément de la même espèce, et sans en préciser la provenance.

description: Consider the set $\mathcal{S}=\lbraceρ_{SE}\rbrace$ of possible initial states of the system-environment. The map which assigns to each $ρ_{S}\in \mathrm{Tr}_{E}\mathcal{S}$ a $ρ_{SE}\in \mathcal{S}$ is called the assignment map. The assignment map is Hermitian, in general. In this paper, we restrict ourselves to the case that the assignment map is, in addition, positive and show that this implies that the so-called reference state is a Markov state. Markovianity of the reference state leads to existence of another assignment map which is completely positive. So, the reduced dynamics of the system is also completely positive. As a consequence, when the system $S$ is a qubit, we show that if $\mathcal{S}$ includes entangled states, then either the reduced dynamics is not given by a map, for, at least, one unitary time evolution of the system-environment $U$, or the reduced dynamics is non-positive, for, at least, one $U$.

description: Effective leadership is like good sex. It is hard to say exactly what makes it good, but you know when you are experiencing it. It requires the right blend of touch, technique, titillation and tact. Despite what leadership manuals may say, there is no perfect recipe. That right blend calls for different combinations of all of these, at different times, and for different purposes. Effective leadership in student support and development services in Australian universities also requires a right blend. People holding formal leadership positions play out these roles as mid-level and senior managers in their institutions. They display leadership not only in terms of operational management of their teams, services and programs, but also at the level of organisational strategy and decision-making around positive learning communities, and student engagement and success.

In this paper we show, following an idea of Witten, how this action follows from supersymmetry, in particular from the symmetries of certain supersymmetric sigma models. In addition, many of the fundamental identities in Hodge-Lefschetz theory are also naturally derived from supersymmetry.

description: This paper analyses the enabling conditions, barriers and future prospects of decentralised experimentation with renewable energy sources (RES) in the German energy transition, with a specific focus on the multi-level governance framework. It investigates why, and under which conditions, decentralised experiments have served as a major driving force in the development of RES in Germany, highlighting the instrumental role local governments and the national support scheme for RES have played in supporting and protecting decentralised RES initiatives. Looking at the impact of decentralised experimentation, this paper argues that the scope of decentralised renewable energy development is now such that there is an obvious need for multi-level governance coordination to address the emerging challenges of temporal and spatial disparities between power generation and demand, as well as distributional and land-use conflicts. The authors observe that many local and regional governments have not yet sufficiently considered the coordination required to make their own efforts compatible with overall energy system transition needs. They may lose their function as important facilitators for RES experimentation if they do not start engaging in new approaches to stakeholder participation, coordinated regional energy flows and system integration of RES. Moreover, bottom-up experimentation with decentralised energy system structures is also threatened by recent changes in the political framework condi-tions at the European and national level which have led to a reform of the German support scheme for RES, including, amongst others, a phase-out of the feed-in tariff scheme and its replacement by an auction scheme. Against the backdrop of these adverse political framework conditions, the paper concludes by discussing strategies to preserve the dynamics of decentralised experimentation as a vigorous driver of the German energy transition.

description: With the growing number of deployments of Internet of Things (IoT) infrastructure for a wide variety of applications, the battery maintenance has become a major limitation for the sustainability of such infrastructure. To overcome this problem, energy harvesting offers a viable alternative to autonomously power IoT devices, resulting in a number of battery-less energy harvesting IoTs (or EH-IoTs) appearing in the market in recent years. Standards activities are also underway, which involve wireless protocol design suitable for EH-IoTs as well as testing procedures for various energy harvesting methods. Despite the early commercial and standards activities, IoT sensing, computing and communications under unpredictable power supply still face significant research challenges. This paper systematically surveys recent advances in EH-IoTs from several perspectives. First, it reviews the recent commercial developments for EH-IoT in terms of both products and services, followed by initial standards activities in this space. Then it surveys methods that enable the use of energy harvesting hardware as a proxy for conventional sensors to detect contexts in energy efficient manner. Next it reviews the advancements in efficient checkpointing and timekeeping for intermittently powered IoT devices. We also survey recent research in novel wireless communication techniques for EH-IoTs, such as the applications of reinforcement learning to optimize power allocations on-the-fly under unpredictable energy productions, and packet-less IoT communications and backscatter communication techniques for energy impoverished environments. The paper is concluded with a discussion of future research directions.

description: We continue to explore the conjectural expressions of the Gromov-Witten potentials for a class of elliptically and K3 fibered Calabi-Yau 3-folds in the limit where the base P^1 of the K3 fibration becomes infinitely large. At least in this limit we argue that the string partition function (=the exponential generating function of the Gromov-Witten potentials) can be expressed as an infinite product in which the Kahler moduli and the string coupling are treated somewhat on an equal footing. Technically speaking, we use the exponential lifting of a weight zero Jacobi form to reach the infinite product as in the celebrated work of Borcherds. However, the relevant Jacobi form is associated with a lattice of Lorentzian signature. A major part of this work is devoted to an attempt to interpret the infinite product or more precisely the Jacobi form in terms of the bound states of D2- and D0-branes using a vortex description and its suitable generalization.

Children's Attention to Proportional Inequality When Making Social Judgments
Creators: Lin, Karina
Publisher: name: Columbia University
Year: 2010
Subjects: subject: Psychology
subject: FOS: Psychology

description: This current study explores how children use their ability to reason proportionally and attend to proportional inequality in social situations. Previous studies have found that adults tend to use their knowledge of proportion to evaluate resource allocations. This perception of fairness is used to judge social traits. In addition, non-human primates have been found to react negatively when an allocation received was less attractive than an allocation received by a conspecific. In this study, children were introduced to two cartoons, each of whom allocated a designated proportion of chips to the child and another amount to a perceived competitor to the child. The children were then asked to judge which cartoon they would prefer to be friends with. Sensitivity to the proportion of resources received compared to the rival would show that the propensity to measure a stranger's resource allocation by using proportion is a behavior enacted by both children and adults. It would also provide additional evidence that children are capable of attending to ratio and proportion before any formal education in the topic. The study found that children performed at chance when selecting which cartoon to be friends with, suggesting that children may not attend to the same social cues that adults attend to when judging friend-worthy traits among new peers.

description: 'Heritage education' is an increasingly popular phrase in both formal and non-formal educational settings. Contemporary heritage education is a teaching lens for the study of cultural heritage. In recent decades, research examining children's heritage education has underscored the many benefits of the practice to a student's personal and academic development, with support for place based education driving an increase in children's heritage education at historic sites. Harnessing immersive, on-site engagements to create 'authentic' and 'active' learning environments, heritage education at historic sites takes on myriad forms (exhibits, tours, performances, fine and dramatic art projects, etc.). In a moment in which heritage education and place based education have become well respected and mainstream educational practices, heritage educational programs at historic sites are diversifying, rethinking, and improving their children's programming, integrating technologically driven experiences to improve site accessibility, and increase diversity of narrative. This project aims to address the current state and future direction of children's heritage education at historic sites, by examining the impact of the Covid-19 pandemic on educational practices. First, the project will contextualize contemporary children's heritage education within the broader histories of heritage education in the United States, and educational theory guiding place and nature based learning methodologies. From here, the thesis addresses the question: How will heritage education at historic sites rise to the challenge of remote site engagement? And, how will these adaptations impact future practices? Conclusions drawn suggest that heritage sites which emphasized heritage education prior to the pandemic, have demonstrated creativity and flexibility in the development of remote and socially distanced site engagements. In doing so, sites have discovered their wider geographic reach, with many sites planning to continue the development of virtual and remote programming in the future. Some sites cite the pandemic as having pushed them to design new engagement strategies and alternative methods of educational enrichment for remote and distanced students. However, as evidence points to the return of field trips and site visits in the near term (and place based learning at historic sites), these new approaches could take on additional meaning; Enrichment materials strengthen a site's overall programming by establishing a subject continuum for pre-visit, on-site experience, and post-visit education, bolstering lesson retention and intellectual curiosity.

The approach is tested for spinless interacting fermions as well as for the Fermi-Hubbard model, and the behavior in the vicinity of special points (such as half filling or isotropic chains) is discussed.We present technical details on how to implement the calculation in practice using the density matrix renormalization group and show that the non-equilibrium dynamics is often less demanding to simulate numerically and features simpler finite-time transients than the corresponding linear response current correlators; thus, new parameter regimes can become accessible. As an application, we determine the thermal Drude weight of the Hubbard model for temperatures T which are an order of magnitude smaller than those reached in the equilibrium approach. This allows us to demonstrate that at low T and half filling, thermal transport is successively governed by spin excitations and described quantitatively by the Bethe ansatz Drude weight of the Heisenberg chain.

description: We here present the synthesis and characterization of a set of biodegradable core–multishell (CMS) nanocarriers. The CMS nanocarrier structure consists of hyperbranched polyglycerol (hPG) as core material, a hydrophobic (12, 15, 18, 19, and 36 C-atoms) inner and a polyethylene glycol monomethyl ether (mPEG) outer shell that were conjugated by ester bonds only to reduce the toxicity of metabolites. The loading capacities (LC) of the drugs, dexamethasone and tacrolimus, and the aggregate formation, phase transitions, and degradation kinetics were determined. The intermediate inner shell length (C15) system had the best overall performance with good LCs for both drugs as well as a promising degradation and release kinetics, which are of interest for dermal delivery
Lagrangian two-spheres can be symplectically knotted

description: This paper shows that there are symplectic four-manifolds M with the following property: a single isotopy class of smooth embedded two-spheres in M contains infinitely many Lagrangian submanifolds, no two of which are isotopic as Lagrangian submanifolds. The examples are constructed using a special class of symplectic automorphisms ("generalized Dehn twists"). The proof uses Floer homology. Revised version: one footnote removed, one reference added

Décrite d’après un mâle et une femelle de la prairie d’altitude à 1000 m sur la piste du Bié (5.XII.1951, Lamotte et Roy), cette espèce brachyptère de couleur générale vert pâle, à longues antennes sombres, n’a fait l’objet que de quelques autres captures, toutes en prairie d’altitude: 5 mâles dans la montée vers le crête du Pierré Richaud à une altitude non notée (28.X.1956, M. Lamotte) et 2 mâles à 1000 m, également dans la montée vers le Pierré Richaud (30.X.1956, M. Lamotte), mentionnés par Dirsh (1963: 216); une femelle mêmes conditions de capture que l’holotype, mentionnée par Popov & Fishpool lors de la description du genre; enfin 1 mâle dans la prairie du camp 1 (fin XI.1951, Lamotte et Roy).
Il s’agit donc d’une espèce rare, adulte en début de saison sèche (octobre-décembre), qui n’est sans doute pas présente partout en prairie d’altitude, où elle n’a jusqu’à présent été signalée que de l’extrémité nord-est.

Dynamical conductivity of the Fermi arc and the Volkov-Pankratov states on the surface of Weyl semimetals

description: Weyl semimetals are known to host massless surface states called Fermi arcs. These Fermi arcs are the manifestation of the bulk-edge correspondence in topological matter and thus are analogous to the topological chiral surface states of topological insulators. It has been shown that the latter, depending on the smoothness of the surface, host massive Volkov-Pankratov(VP) states that coexist with the chiral ones. Here, we investigate these VP states in the framework of Weyl semimetals, namely their density of states and magneto-optical response. We find the selection rules corresponding to optical transitions which lead to anisotropic responses to external fields. In the presence of a magnetic field parallel to the interface, the selection rules and hence the poles of the response functions are mixed.

Children's Perception of Conversational and Clear American-English Vowels in Noise
Creators: Leone, Dorothy
Publisher: name: Columbia University
Year: 2013
Subjects: Speech therapy

description: A handful of studies have examined children's perception of clear speech in the presence of background noise. Although accurate vowel perception is important for listeners' comprehension, no study has focused on whether vowels uttered in clear speech aid intelligibility for children listeners. In the present study, American-English (AE) speaking children repeated the AE vowels /ε, æ, ɑ, ʌ/ in the nonsense word /gəbVpə/ in phrases produced in conversational and clear speech by two female AE-speaking adults. The recordings of the adults' speech were presented at a signal-to-noise ratio (SNR) of -6 dB to 15 AE-speaking children (ages 5.0-8.5) in an examination of whether the accuracy of AE school-age children's vowel identification in noise is more accurate when utterances are produced in clear speech than in conversational speech. Effects of the particular vowel uttered and talker effects were also examined. Clear speech vowels were repeated significantly more accurately (87%) than conversational speech vowels (59%), suggesting that clear speech aids children's vowel identification. Results varied as a function of the talker and particular vowel uttered. Child listeners repeated one talker's vowels more accurately than the other's and front vowels more accurately than central and back vowels. The findings support the use of clear speech for enhancing adult-to-child communication in AE, particularly in noisy environments.
Scales and hierarchies in warped compactifications and brane worlds

description: Warped compactifications with branes provide a new approach to the hierarchy problem and generate a diversity of four-dimensional thresholds. We investigate the relationships between these scales, which fall into two classes. Geometrical scales, such as thresholds for Kaluza-Klein, excited string, and black hole production, are generically determined soley by the spacetime geometry. Dynamical scales, notably the scale of supersymmetry breaking and moduli masses, depend on other details of the model. We illustrate these relationships in a class of solutions of type IIB string theory with imaginary self-dual fluxes. After identifying the geometrical scales and the resulting hierarchy, we determine the gravitino and moduli masses through explicit dimensional reduction, and estimate their value to be near the four-dimensional Planck scale. In the process we obtain expressions for the superpotential and Kahler potential, including the effects of warping. We identify matter living on certain branes to be effectively sequestered from the supersymmetry breaking fluxes: specifically, such "visible sector" fields receive no tree-level masses from the supersymmetry breaking. However, loop corrections are expected to generate masses, at the phenomenologically viable TeV scale.

Espèce peu commune qui n’avait pas encore été signalée du Nimba. Toutes les captures, sauf une qui provient de la mission Lamotte II-VI.1942 sans autre précision, ont été faites en mars 1981 dans une savane près de Sérengbara, en prairie à 1200 m sur la piste de Zouguépo, et surtout en prairie sur cuirasse près de Gbakoré (34 spécimens sur les 47 recueillis en tout). Aucun jeune n’a été capturé, ou tout au moins reconnu (confusion possible avec ceux de l’espèce précédente).

Coin Theorems and the Fourier Expansion
Creators: name: Agrawal, Rohit
Publisher: name: arXiv
Year: 2019
Subjects: subject: Computational Complexity (cs.CC)
subject: FOS: Computer and information sciences

description: In this note we compare two measures of the complexity of a class $\mathcal F$ of Boolean functions studied in (unconditional) pseudorandomness: $\mathcal F$'s ability to distinguish between biased and uniform coins (the coin problem), and the norms of the different levels of the Fourier expansion of functions in $\mathcal F$ (the Fourier growth). We show that for coins with low bias $\varepsilon = o(1/n)$, a function's distinguishing advantage in the coin problem is essentially equivalent to $\varepsilon$ times the sum of its level $1$ Fourier coefficients, which in particular shows that known level $1$ and total influence bounds for some classes of interest (such as constant-width read-once branching programs) in fact follow as a black-box from the corresponding coin theorems, thereby simplifying the proofs of some known results in the literature. For higher levels, it is well-known that Fourier growth bounds on all levels of the Fourier spectrum imply coin theorems, even for large $\varepsilon$, and we discuss here the possibility of a converse.

description: Over the last century, Chinese Foreign Direct Investments have made great impacts on African countries. Large amounts of FDI from China has flooded into African infrastructure investments, targeting key sectors such as telecommunications, transportation, power plants, and port refurbishments. No doubt China treats itself as an equal and a generous partner of African countries, yet not an uncontroversial one especially from the perspective of foreign observers. There have been many critical voices on China-Africa relations over the years. In order to test the validity of the critiques as well as the praises, two infrastructure construction projects were chosen as case studies in this thesis. They are the Standard Gauge Railroad and A109 national road. Both contracts were signed between the Kenyan government and a Chinese state-owned company, Chinese Road and Bridge Cooperation (CRBC). By analyzing the first hand data and some supplementary second hand data, it indicates that though CRBC as contractor had made some decisions based on self-interests, the critics of labor importation and resource plunder lack supporting evidence. Instead, for these particular projects, they generated positive economic impacts on national development. However, many improvements are highly recommended for both parties to make the projects better in the future.
