Archivos profanados
Authors: Morales Noelia 
Published: September 2024

En este trabajo nos centraremos en las obras Mi vida después (2009) de la artista argentina Lola Arias y Antígona Oriental (2012) de la dramaturga uruguaya Marianella Morena. Para ello, tomaremos como uno de los ejes posibles de análisis, el estudio comparativo de los archivos y sus vínculos con las formas de actuación a partir del concepto de profanación de Giorgio Agamben (2013) y la reapropiación realizada por Lía Noguera (2019) en el campo de las artes.
IMPACT OF PUBLIC EXPENDITURE ON NIGERIA ECONOMY
Authors: AHAKIRI FRANCIS IDIEGE , RAPHAEL IMONG NELLY , NKANG MARY EYONG 
Published: September 2024

This study investigated the effect of public expenditure on Nigerian economy for the period of thirty years, from 1990-2019. Ex-post facto research design was adopted. The data used in this study were secondary data derived from the Central Bank of Nigeria Statistical Bulletin Annual Reports and Accounts. The study used regression analysis and the result revealed that both economic service and social service expenditure have positive significant effect on Nigeria economy (RGDP). The study concluded that economic service and social service expenditures have effects on Nigerian economic growth. The study recommended that the government should increase public spending on social services. This can be accomplished by utilizing public funding to improve educational quality at all levels of learning (primary, secondary, and higher education) through training programs that give the skills and information needed to increase labor productivity and create additional job possibilities. Furthermore, public spending in the health and social security sectors should be directed toward constructive expenditures that promote economic growth.
Mythes, erreurs et paradoxes dans l’interprétation de la règle de conflit sur les obligations non contractuelles
Authors: Chikoc Barreda Naivi 
Published: September 2024

Ce texte contient une réflexion critique de l’interprétation de l’article 3126 du Code civil du Québec (CcQ) qui domine dans la jurisprudence québécoise. Le raisonnement préconisant la primauté de la lex loci delicti fondé sur le mythe de la territorialité des lois dans ce domaine révèle une conception dépassée de la responsabilité civile. La justification territorialiste basée sur l’arrêt Tolofson contredit le fondement de la règle de conflit en la matière, qui repose sur la proximité et la prévisibilité de la loi applicable au rapport délictuel. Les arrêts analysés démontrent que le recours à la lex loci delicti s’est avéré l’instrument pour éviter certains résultats perturbateurs, notamment l’application éventuelle d’une pluralité de lois. Le territorialisme est ainsi instrumentalisé au détriment de la solution codifiée par le législateur. Il en résulte un renversement de l’ordre des critères de rattachements prévu à l’article 3126 du CcQ motivé par des erreurs et des paradoxes interprétatifs que l’auteure se propose de dévoiler et de corriger.
Femmes autochtones et discrimination au canada : analyse du droit à la réparation des peuples autochtones à la lumière de la notion de fait internationalement illicite à caractère continu
Authors: Décoste Éloïse 
Published: September 2024

Durant plus d’un siècle, les dispositions de la Loi sur les Indiens relatives à l’admissibilité au statut « Indien » étaient discriminatoires envers les femmes autochtones. En vertu de ce régime législatif, lorsqu’une femme autochtone mariait un homme allochtone, elle perdait son statut « Indien » et les enfants issus de ce mariage n’y avaient pas droit non plus. Ce n’était pas le cas toutefois pour les hommes autochtones qui eux dans des circonstances semblables conservaient le leur. Or, sans statut, ces femmes n’étaient plus perçues formellement comme autochtones aux yeux de l’État canadien. Par conséquent, elles ne pouvaient plus vivre dans leur communauté, ni y participer à la vie politique et sociale, et se voyaient privées de la possibilité d’élever leurs enfants au sein de leur culture, de leur langue et de leurs traditions. Cette exclusion contribua à la marginalisation économique, à l’isolement social et à la dévalorisation de la vie des femmes autochtones.
Influence of sea ice on ocean water vapor isotopes and Greenland ice core records
Authors: Klein Eric S. , Welker Jeffrey M. 
Published: December 2016

AbstractA warming climate results in sea ice loss and impacts to the Arctic water cycle. The water isotope parameter deuterium excess, a moisture source proxy, can serve as a tracer to help understand hydrological changes due to sea ice loss. However, unlocking the sea ice change signal of isotopes from ice cores requires understanding how sea ice changes impact deuterium excess, which is unknown. Here we present the first isotope data linking a gradient of sea ice extents to oceanic water vapor deuterium excess values. Initial loss of sea ice extent leads to lower deuterium excess moisture sources, and then values progressively increase with further ice loss. Our new process‐based interpretation suggests that past rapid (1–3 years) Greenland ice core changes in deuterium excess during warming might not be the result of abrupt atmospheric circulation shifts, but rather gradual loss of sea ice extent at northern latitude moisture sources.

AbstractParallel electric fields and their associated electric potential structures play a crucial role in ionospheric‐magnetospheric interactions at any planet. Although there is abundant evidence that parallel electric fields play key roles in Martian ionospheric outflow and auroral electron acceleration, the fields themselves are challenging to directly measure due to their relatively weak nature. Using measurements by the Solar Wind Electron Analyzer instrument aboard the NASA Mars Atmosphere and Volatile EvolutioN (MAVEN) Mars Scout, we present the discovery and measurement of a substantial (ΦMars=7.7 ± 0.6 V) parallel electric potential drop on closed magnetic field lines spanning the terminator from day to night above the great impact basin of Utopia Planitia, a region largely free of crustal magnetic fields. A survey of the previous 26 orbits passing over a range of longitudes revealed similar signatures on seven orbits, with a mean potential drop (ΦMars) of 10.9 ± 0.8 V, suggestive that although trans‐terminator electric fields of comparable strength are not ubiquitous, they may be common, at least at these northerly latitudes.
The Gendered Transition to Parenthood: Lasting Inequalities in the Home and in the Labor Market
Authors: Evertsson Marie , Boye Katarina 
Published: December 2016

AbstractWe discuss the slow process through which the gendered transition to parenthood has changed in Western societies and the degrees to which this process challenges economic theories on the utility‐maximizing rational man, woman, and/or couple. The transition to parenthood has long‐term consequences for women's careers, often even in couples in which the woman earns more than the man. The reason for the slow‐changing process can partially be found in gender norms and the physical aspects of the transition to motherhood, including breastfeeding and norms regarding how long the child benefits from being in the mother's care. One of the challenges faced by research on the gendered transition to parenthood is how to distinguish where the boundaries between biology and gender norms lie. We discuss the gendered transition to parenthood and its career‐related consequences, and we elaborate on potential ways in which research may advance to dismantle the interconnected nature of biology, gender, and economic reasoning in couples' transition to parenthood.
Deliberative Democracy
Authors: Fishkin James 
Published: December 2016

AbstractAt the center of the idea, deliberative democracy is that the “will of the people” should be based on the consideration of competing arguments about their merits of each policy choice. Despite this, partisanship and electoral campaigns are designed to win elections, not promote citizen deliberation. The focus of most modern research on deliberation by ordinary citizens rather than by representatives or office holders raises interesting questions about who deliberates, what is the policy context, what rationale is used, and what criteria should evaluate deliberative processes. Access to accurate information, relevant arguments, and a representative sample are necessary for good conditions. Some criteria for evaluation include demographic and attitudinal representativeness, sample size, the opportunity to engage in arguments for and against proposals, and the elimination of distortion (e.g., misleading information).
An Emerging Trend: Is Big Data the End of Theory?
Authors: Macy Michael W. 
Published: December 2016

Abstract“Big data” from online communities opens up unprecedented opportunities for social scientists to track human behavior and social interaction in real time and on the individual level yet on a global scale. Will the empirical windfall make theory unnecessary by allowing scientists to search for whatever pattern is “out there,” expected or otherwise? This essay argues that the deluge of relational data promises a new beginning for causal explanation, for two reasons. First, these new sources of data—from friends, peers, neighbors, colleagues, and coworkers—avoid the atomistic theoretical bias imposed by a half century of reliance on surveys administered to stratified random samples. Second, the growing ability to conduct online experiments with randomized trials makes it possible to test theories about the causal processes that underlie observed patterns.
Partisan News: A Perspective from Economics
Authors: Stone Daniel F. 
Published: December 2016

AbstractI briefly summarize the economics literature on ideologically slanted political media (which I call, for short, partisan news), and discuss directions for future research. In the literature review, I take a history of thought approach, describing how theory and empirical work have fed off one another and real‐world events. I also note ways in which the work of economists differs from comparable work from other disciplines. In the discussion of future research, I identify open questions and policy options, and assess the relationship between research from economics and other disciplines.

Published: December 2016

AbstractAn inexpensive ruthenium‐catalyzed direct C–H olefination of aromatic carboxamides with allyl acetate was developed. This external oxidant‐free protocol provided an efficient route for the synthesis of useful trans‐styrene derivatives in high to excellent yields. The olefination reaction exhibited excellent regioselectivities and allowed the presence of a wide range of functional groups, such as OMe, F, Cl, Br, I, CF3, NMe2, as well as NO2.magnified image
Diverse Transformations of Boronic Compounds Promoted by Hypervalent Organoiodines(III): Unique Combined Reactivity of Two Electrophilic Compounds
Authors: Chatterjee Nachiketa , Goswami Avijit 
Published: December 2016

AbstractBoth hypervalent organoiodine(III) compounds and boronic acids/esters are non‐toxic and considered as environment‐friendly compounds and have had a remarkable impact on the field of synthetic organic chemistry. Numerous transformations have been carried out using hypervalent organoiodine(III) or boronic acids/esters – taken separately – with other reactants, but transformations with these two reagents taken together are comparatively less well reported. In this mini‐review, diverse reactions carried out with these two substrates in the presence of each other, have been discussed. Various functionalizations of boronic compounds, promoted by hypervalent organoiodine(III) reagents, both in the presence and absence of transition metals, have been reviewed. Different metal‐free iodine(III)–boron exchange reactions providing iodonium salts, various ipso transformations of boronic acids/esters and metal‐catalyzed cross‐coupling reactions of boronic compounds with hypervalent organoiodine(III) reagents are the prime focal areas of this article. Mechanistic aspects for certain reactions have also been delineated.magnified image
Copper‐Catalyzed Difunctionalization of Terminal Alkynes with Diazo Esters and Amines to Construct β‐Enamino Esters
Authors: Gao Bao , Huang Hanmin 
Published: December 2016

AbstractAn operationally simple and efficient copper‐catalyzed three‐component tandem reaction of terminal alkynes, diazo compounds and amines to yield β‐enamino esters is described. This straightforward protocol takes place rapidly with a wide range of substrates and gives the desired β‐enamino esters in good to excellent yields. Preliminary mechanistic studies suggested that the reaction probably proceeds through Cu‐catalyzed formal C–H insertion to produce an alkynoate intermediate, which was then trapped by amines to give the β‐enamino esters.magnified image

Derivation and application of quantum Hamilton equations of motion
Authors: Köppe J. , Grecksch W. , Paul W. 
Published: December 2016

Non‐relativistic quantum systems are analyzed theoretically or by numerical approaches using the Schrödinger equation. Compared to the options available to treat classical mechanical systems this is limited, both in methods and in scope. However, based on Nelson's stochastic mechanics, the mathematical structure of quantum mechanics has in some aspects been developed into a form analogous to classical analytical mechanics. We show here that finding the Nash equilibrium for a stochastic optimal control problem, which is the quantum equivalent to Hamilton's principle of least action, allows to derive two things: i) the Schrödinger equation as the Hamilton‐Jacobi‐Bellman equation of this optimal control problem and ii) a set of quantum dynamical equations which are the generalization of Hamilton's equations of motion to the quantum world. We derive their general form for the non‐stationary and the stationary case. For the harmonic oscillator, the stationary equations lead to the coherent states, and we establish a numerical procedure to solve for the ground state properties without using the Schrödinger equation.

AbstractCombining vertically resolved lidar retrievals of water vapor and cloud detection, we document a 2‐day subtropical cirrus case study over La Réunion (20.9°S–55.5°E) in March 2005, focusing on the conditions of ice supersaturation inside and near the observed cloud. Using satellite observations, we describe the synoptic conditions leading to cloud formation. Supersaturation occurs 25% of the time within the cirrus, up to 35% in its middle segment, where relative humidity goes beyond 150%. In clear‐sky areas, relative humidity stays consistently low, especially in profiles without clouds. High‐troposphere atmospheric waves could initiate the formation of supersaturation conditions, especially on 16 March.
Added value of high resolution models in simulating global precipitation characteristics
Authors: Zhang Lixia , Wu Peili , Zhou Tianjun , Roberts Malcolm J. , Schiemann Reinhard 
Published: December 2016

AbstractClimate models tend to overestimate percentage of the contribution (to total precipitation) and frequency of light rainfall while underestimate the heavy rainfall. This article investigates the added value of high resolution of atmospheric general circulation models (AGCMs) in simulating the characteristics of global precipitation, in particular extremes. Three AGCMs, global high resolution atmospheric model from the Geophysical Fluid Dynamics Laboratory (GFDL‐HiRAM), the Meteorological Research Institute‐atmospheric general circulation model (MRI‐AGCM) and the Met Office Unified Model (MetUM), each with one high and one low resolution configurations for the period 1998–2008 are used in this study. Some consistent improvements are found across all three AGCMs with increasing model resolution from 50–83 to 20–35 km. A reduction in global mean frequency and amount percentile of light rainfall (<11 mm day−1) and an increase of medium to heavy rainfall (>20 mm day−1) are shown in high resolution models of GFDL‐HiRAM and MRI‐AGCM, while the improvement in MetUM is not obvious. A consistent response to high resolution across the three AGCMs is seen from the increase of light rainfall frequency and amount percentile over the desert regions, particularly over the ocean desert regions. It suppresses the overestimation of CDD over ocean desert regions and makes a better performance in high resolution models of GFDL‐HiRAM and MRI‐AGCM, but worse in MetUM‐N512. The impact of model resolution differs greatly among the three AGCMs in simulating the fraction of total precipitation exceeding the 95th percentile daily wet day precipitation. Inconsistencies among models with increased resolution mainly appear over the tropical oceans and in simulating extreme wet conditions, probably due to different reactions of dynamical and physical processes to the resolution, indicating their crucial role in high resolution modelling.

AbstractIn this study, the whole proteins from a Chinese three‐striped box turtle (Cuora trifasciata) were extracted and hydrolyzed using three proteases (alcalase, papain, and protamex). By orthogonal experiments, the optimal hydrolysis conditions for producing peptides with the highest cancer cells growth inhibition activity were determined. Such as, the maximum inhibition on MCF‐7 cancer cells (92.37% at 1 mg/mL) was achieved by papain hydrolysis (pH 8, 37 °C, enzyme‐to‐substrate ratio (E/S) 1.5%), and the maximum inhibition on HepG2 cancer cells (94.16% at 1 mg/mL) was reached by protamex hydrolysis (pH 8, 40 °C, E/S 2%). Using ultrafiltration and Sephadex G‐15 column chromatography, two polypeptides M2 and F4 were isolated. At 500 μg/mL, M2 exhibited 74.7% and 62.9% of antiproliferation activities on MCF‐7 and HepG2 cancer cells, respectively; and F4 displayed good inhibitory effects on MCF‐7 (70.59%) and HepG2 (78.6%) cancer cells. M2 and F4 had lower inhibition (<20%) than drug 5‐FU (>60%) on normal liver cells L‐O2. Moreover, three peptides, EMLQPPL, PGKPLFL, and SCCSCDED, were identified; their inhibitory effects on cancer cells were confirmed after synthesis. These data, for the first time, demonstrated that Cuora trifasciata–derived proteins could be used for preparing antiproliferation peptides.

AbstractCoptisine, one of the main components isolated from Coptidis rhizoma, has been reported to have many beneficial pharmacological effects including anti‐inflammatory, anti‐hypercholesterolemia, neuroprotective and cardioprotective properties. However, to date the information related to the in vivo pharmacokinetics (PK) of coptisine is very limited. The purposes of our study are to establish a fast and sensitive quantification method of coptisine using liquid chromatography–mass spectrometry (LC–MS) and evaluate the PK profile of coptisine in rats. The calibration curve for coptisine was linear from 0.78 to 50 ng/mL. After single‐dose oral administration of coptisine, the mean peak plasma concentration values for groups treated with 30, 75 and 150 mg/kg doses ranged from 44.15 to 66.89 ng/mL, and the mean area under the concentration–time curve values ranged from 63.24 to 87.97 mg/L h. The absolute bioavailability was calculated to range from 1.87 to 0.52%. Coptisine remained in all analyzed samples at low concentrations after oral administration of 30 mg/kg.
