ON SOME NEW PARANORMED SEQUENCE SPACES OF FUZZY NUMBERS DEFINED BY ORLICZ FUNCTIONS AND STATISTICAL CONVERGENCE
Authors: Esi A.
Published: March 2019

In this paper we introduce the concept of strongly λ(p) convergence of fuzzy numbers with respect to an Orlicz function and examine some properties of the resulting sequence spaces and λ(p) – statistical convergence. It is also shown that if a sequence of fuzzy numbers is strong λ(p) convergent with respect to an Orlicz function then it is λ(p) – statistically convergent.
Geometric morphometric analysis of the pronotum and elytron in stag beetles: insight into its diversity and evolution
Authors: Zhang Mengna , Ruan Yongying , Wan Xia , Tong Yijie , Yang Xingke , Bai Ming
Published: March 2019

Stag beetles (Coleoptera, Scarabaeoidea, Lucanidae) have received extensive attention from researchers in behavioral ecology and evolutionary biology. There have been no previous quantitative analyses, particularly using a geometric morphometric approach based on a large sample of data, to shed light on the morphological diversity and evolution of Lucanidae. Thoracic adaptation and ecological differentiation are intimately related, and the pronotum bears important muscles and supports the locomotion of prothoracic legs. The elytron is an autapomorphy of the Coleoptera. To reconstruct and visualize the patterns of evolutionary diversification and phylogenetic history of shape change, an ancestral groundplan can be reconstructed by mapping geometric morphometric data onto a phylogenetic tree. In this study, the morphologies of the pronotum and elytron in 1303 stag beetles (Lucanidae), including approximately 99.2% of all globally described species, were examined, thus revealing several aspects of morphological diversity and evolution. First, on the basis of geometric morphometric analysis, we found significant morphological differences in the pronotum or elytron between any two Lucanidae subfamilies. And we subsequently reconstructed the ancestral groundplans of the two structures in stag beetles and compared them with those of extant species (through cladistic and geometric morphometric methods). The ancestral groundplan of Lucanidae was found to be most similar to extant Nicagini in both the pronotum and elytron, according to Mahalanobis distances. Furthermore, we analyzed species richness and morphological diversity of stag beetles and the relationships between them and found that the two parameters were not always correlated. Aesalinae was found to be the most diverse subfamily in both the pronotum and elytron, despite its poor species richness, and the diversity of the pronotum or elytron was not superior in Lucaninae, despite its high species richness. Our study provides insights into the morphological variations and evolutionary history of the pronotum and elytron in four subfamilies of stag beetles, and it illuminates the relationship between morphological diversity and species richness. Intriguingly, our analysis indicates that morphological diversity and species richness are not always correlated. These findings may stimulate further studies in this field.

Authors: Abburu Sunitha , Golla Suresh Babu
Published: March 2019

3D city model construction adopting OGC standards is the need of the hour for many countries. Research is heading towards effective methods for data collection for the 3D city model development process and disseminating all 3D city objects data of a specific user choice of region, through OGC web services. The current research work aims at building 3DCity LOD1 models using 2D geospatial data, disseminating the 3DCity objects information through OGC web services for a geographic region, building an ADE for modelling critical infrastructure such as electric lines, water pipes, etc., and modelling 2D critical infrastructure data in 3D CityGML model using the ADE. Models can be visualized using any CityGML visualizer like FME, Aristoteles, etc. The CityGML model is validated using OGC CityGML schema validator. Sample region based WFS results are shown along with the WFS performance test using a web services benchmark. CI ADE is validated through writing powerlines geospatial feature into CityGML model.
Digital Elevation Modeling Analysis for Investigation of Gravity Hill Phenomena
Authors: Jamil Rehan
Published: March 2019

This article presents an investigation of the gravity hill phenomena by analysing its geospatial data. Wadi Al Baida located in Al Madinah, Saudi Arabia has been taken as a case study. Wadi Al Baida is listed as one of the sites in the world where the said phenomena exists, but the site has been famous for any sort of magnetic force because the vehicles move uphill and on flat road without any engine power on. The topography of the valley is studied by using the geospatial data of the area and by creating Digital Elevation Models (DEMs) based on Point Kriging method of gridding. The results show that the area has natural slope and there is a significant difference in the elevations of the start and the end point of the valley. A longitudinal profile is also generated to validate the results obtained by DEMs and it is found that the road has an average slope of 2.6% which makes the vehicles and rolling objects move on their own due to the force of gravity. Also, the concept of gravity hill has been explained with the help of a diagram which is easy to understand by the readers.

Published: March 2019

The need to remotely control home appliances is an important aspect of home automation and is now receiving lot of attentions in the literature. The works so far are still at a development level making further research necessary. This article presents a framework for chatbot-controlled home appliance control system and was implemented by programming a Raspberry Pi using the Python language while the chatbot server was also implemented using a Node.js on JavaScript. The Raspberry Pi was connected to the chatbot server via Wi-Fi using a websockets protocol. The chatbot server is linked to Facebook Messenger using the Messenger Application Protocol Interface. Messages received at the chatbot server are analyzed with RasaNLU to classify the user's intention and extract necessary information which are sent over websocket to the connected Raspberry pi. The system was evaluated using control precision and percentage correct classification with both producing a significant level of acceptance. This work produced a Facebook Messenger chatbot-based framework capable of controlling Home Appliances remotely.

Authors: Mounir Achouri , Adel Alti , Makhlouf Derdour , Sébastien Laborie , Philippe Roose
Published: March 2019

In the field of smart environments, many devices and multimedia-oriented connected objects have gained a significant attention in recent years. There is a critical need to offer to users flexible and efficient service selection among a large set of candidates based on their surrounding environments, the user's current needs and situations. This article aims to provide a new Generic Context-aware Profile ONTOlogy (GCxPOnto) for a semantic description of heterogeneous profiles with a situations management facility related to smart environments. Based on the GCxPOnto ontology model, a two-layered architecture was proposed. It includes a local server with a sematic profile modeling and a central Cloud that provides efficient situation management and good scalability. This article is divided into three phases: profile clustering, situation management, and multimedia information dissemination related to smart services. The experimental results show a good response time and an enhanced situational accuracy.

An Efficient Privacy-preserving Approach for Secure Verifiable Outsourced Computing on Untrusted Platforms
Authors: Olakanmi Oladayo Olufemi , Dada Adedamola
Published: March 2019

In outsourcing computation models, weak devices (clients) increasingly rely on remote servers (workers) for data storage and computations. However, most of these servers are hackable or untrustworthy, which makes their computation questionable. Therefore, there is need for clients to validate the correctness of the results of their outsourced computations and ensure that servers learn nothing about their clients other than the outputs of their computation. In this work, an efficient privacy preservation validation approach is developed which allows clients to store and outsource their computations to servers in a semi-honest model such that servers' computational results could be validated by clients without re-computing the computation. This article employs a morphism approach for the client to efficiently perform the proof of correctness of its outsourced computation without re-computing the whole computation. A traceable pseudonym is employed by clients to enforce anonymity.
Change Detection in Large Evolving Networks
Authors: Namayanja Josephine M. , Janeja Vandana P.
Published: March 2019

This article presents a novel technique for the detection of change in massive evolving communication networks. This approach utilizes a novel hybrid sampling methodology to select central nodes and key subgraphs from networks over time. The objective is to select and utilize a much smaller targeted sample of the network, represented as a graph, without loss of any knowledge derived from graph properties as compared to the entire massive graph. This article uses the targeted samples to detect micro- and macro-level changes in the network. This approach can be potentially useful in the domain of cybersecurity where this article highlights the importance of graph sampling and multi-level change detection in identifying network changes that may be difficult to detect on a larger scale. This article therefore presents a means to audit large networks to establish continuous awareness of network behavior.
Can WordBricks Make Learning Irish More Engaging for Students?
Authors: Ward Monica , Mozgovoy Maxim , Purgina Marina
Published: March 2019

Learning a language is challenging and it is important that learners be kept motivated throughout the process. Many Irish primary school children are not particularly motivated to learn the language and there are few computer assisted language learning (CALL) resources available to them. WordBricks is an app that enables learners to construct only grammatically correct sentences. It leverages a visual learning paradigm and has a Scratch-like interface. It was originally developed for English, and more recently has been expanded to cater for Irish. This article investigates if using Irish WordBricks is both suitable and usable for primary school learners, if it is pedagogically appropriate for them and if it is enjoyable for them. The WordBricks app was tested by five classes of two different age groups in a typical school in Ireland. This article reports on the results of the WordBricks deployment and the feedback of students and teachers.
Cost Minimization Through Load Balancing and Effective Resource Utilization in Cloud-Based Web Services
Authors: Das More Swami , Govardhan A. , Lakshmi Doddapaneni Vijaya
Published: March 2019

With the growth of internet-based applications and the explosion of consumers, cloud-based web service applications have become more common and the importance of minimizing the cost, increasing the interactivity, and management and efficient use of resources has become high. Existing methods like fixed cost per month no longer satisfy the application maintenance costs of the modern app developers. In this article, the authors propose an enhanced model for improving efficiency; maximize availability and minimizing the cost of cloud-based web applications. The authors have conducted experiments on grid dataset and analyzed the results using several algorithms on the load balancer with the multilevel optimized shortest remaining time scheduling method. The analysis clearly proves that applying a “pay as you” go mechanism will substantially reduce the cost and will improve the efficiency which resources are utilized. The results clearly suggest improvements in cost minimization and effective utilization of resources leading to effective utilization of services.

Published: March 2019

Employee participation in IT projects in the public sector is argued in the literature as a critical factor for the success and acceptance of IT. However, studies on employee participation reported on the lack of end-users participation in the public sector and on the need of improvement of participation concepts. This article investigates different participation practices and used methods for participation within different approaches such as Human Centered Design, Ethnography, Contextual Design and Human Resource Management, and explores opportunities for participation across the system developement life cycle in the public sector. The findings reveal a variety of participation opportunieties across the whole process. Finally, implications of these findings are discussed with suggestions for future research.
Regeneration of Waste Diatomite from Palm Oil Production Process as a Support Material for PCMs in Thermal Energy Storage in Buildings
Authors: Acurio Karen , Chico-Proano Andrés , Martínez-Gómez Javier , Orozco Marco
Published: March 2019

In this study, the use of spent diatomite, an industrial waste in the palm oil production process, was evaluated as a support material for phase change materials (PCMs). Calcination tests of the diatomite were carried out at different temperatures (400, 550 and 700 °C) and times (1 and 2 h). For the PCMs preparation, the organic phase, mixtures of palm oil and commercial stearic acid esters, were impregnated on calcined diatomite under vacuum. Differential scanning calorimetry (DSC) analyses were performed in order to select the PCM with the highest latent heat of fusion and a range of phase change temperature corresponding to the thermal comfort range. DSC, TGA and FT-IR analyses were performed before and after the application of 360 thermal cycles to establish the thermal and chemical reliability of the PCM. It was found that 700 °C and 1 h are the best conditions of the calcination process, and the PCM consisting in 100 % methyl esters of commercial stearic acid presented the highest value of latent heat of fusion (34.67 J/g) and a phase change temperature range of 16.4 to 33.5 °C. After the thermal cycles, the results show that the prepared PCMs has thermal and chemical stability.
Mechanical Properties of New Sustainable Polymeric Formulations for Rotomoulding Processes
Authors: Martínez-García Asunción , Ibáñez-García Ana , Varela-Gandía Francisco José
Published: March 2019

This paper shows the results of the mechanical characterisation of a series of new sustainable polymeric formulations filled with almond shell and cellulosic fibres for its use in rotomoulding process. Up to ten formulations of polyethylene and polycaprolactone, were developed with a content from 10 to 40 wt% of natural filler. The addition of these fillers decreased the mechanical properties, mainly when the formulation was carried out by physical mixing. However, good interfacial interaction between the polymer and filler was produced in the compounding process, obtaining final formulations appropriated for rotomoulding.
On tensor products of CSS codes
Authors: Audoux Benjamin , Couvreur Alain
Published: March 2019

CSS codes are in one-to-one correspondance with length 3 chain complexes. The latter are naturally endowed with a tensor product

\otimes

which induces a similar operation on the former. We investigate this operation, and in particular its behavior with regard to minimum distances. Given a CSS code

\mathcal C

, we give a criterion which provides a lower bound on the minimum distance of

\mathcal C \otimes \mathcal D

for every CSS code

\mathcal D

. From this criterion arises a generic bound for the minimum distance which is twice larger than the single bound previously known in the literature. We apply these results to study the behaviour of iterated tensor powers of codes. Such sequences of codes are logarithmically LDPC and we prove in particular that their minimum distances tend generically to infinity. More precisely, their minimum distance increases as

O(n^\alpha)

for some

\alpha > 0

, where

n

is the code length, while the row weight of their parity–check matrices grows as

O(\log(n))

. This entails a rather surprizing fact: even if a CSS code does not have quantum degeneracy, for a large enough

\ell

, its

\ell

-th iterated tensor power does. Different known results are also reinterpretated in terms of tensor products and three new families of LDPC CSS codes are studied.
Eigenvalue bounds and spectral asymptotics for fractal Laplacians
Authors: Pinasco Juan Pablo , Scarola Cristian
Published: March 2019

In this work we present Lyapunov type inequalities for generalized one dimensional Laplacian operators defined by positive atomless Borel measures. As applications, we present lower bounds for the first eigenvalue when the measure is a Bernoulli convolution, with or without overlaps. Also, for symmetric Bernoulli convolutions we obtain two sided bounds for higher eigenvalues, and we recover the asymptotic growth of the spectral counting function by elementary means without using the Renewal Theorem.
Non-degeneracy of the harmonic structure on Sierpiński gaskets
Authors: Tsougkas Konstantinos
Published: March 2019

We prove that the harmonic extension matrices for the two dimensional level-

k

Sierpiński gasket are invertible for every

k \geq 2

. This has been previously conjectured to be true by Hino in [10] and [11] and tested numerically for

k \leq 50

. We also give a necessary condition for the non-degeneracy of the harmonic structure for general finitely ramified self-similar sets based on the vertex connectivity of their first graph approximation.
Quantization of the affine group of a local field
Authors: Gayral Victor , Jondreville David
Published: March 2019

For a non-Archimedean local field which is not of characteristic 2, nor an extension of

\mathbb Q_2

, we construct a pseudo-differential calculus covariant under a unimodular subgroup of the affine group of the field. Our phase space is a quotient group of the covariance group. Our main result is a generalization on that context of the Calderón–Vaillancourt estimate. Our construction can be thought as the non-Archimedean version of Unterberger’s Fuchs calculus and our methods are mainly based on Wigner functions and on coherent states transform.
Spectral triples for the variants of the Sierpiński gasket
Authors: Arauza Rivera Andrea
Published: March 2019

Fractal geometry is the study of sets which exhibit the same pattern at multiple scales. Developing tools to study these sets is of great interest. One step towards developing some of these tools is recognizing the duality between topological spaces and commutative

C*

-algebras. When one lifts the commutativity axiom, one gets what are called noncommutative spaces and the study of noncommutative geometry. The tools built to study noncommutative spaces can in fact be used to study fractal sets. In what follows we will use the spectral triples of noncommutative geometry to describe various notions from fractal geometry. We focus on the fractal sets known as the harmonic Sierpiński gasket and the stretched Sierpiński gasket, and show that the spectral triples constructed in [7] and [23] can recover the standard self-affine measure in the case of the harmonic Sierpiński gasket and the Hausdorff dimension, geodesic metric, and Hausdorff measure in the case of the stretched Sierpiński gasket.
Asymptotic shape optimization for Riesz means of the Dirichlet Laplacian over convex domains
Authors: Larson Simon
Published: March 2019

For

\Omega \subset \mathbb{R}^n

, a convex and bounded domain, we study the spectrum of

-\Delta_\Omega

the Dirichlet Laplacian on

\Omega

. For any

\Lambda \geq 0

and

\gamma \geq 0

let

\Omega_{\Lambda, \gamma}(\mathcal{A})

denote any extremal set of the shape optimization problem

\mathrm {sup}\{ \mathrm {Tr}(-\Delta_\Omega-\Lambda)_–^\gamma \colon \Omega \in \mathcal A, |\Omega|=1\}

where

\mathcal A

is an admissible family of convex domains in

\mathbb R^n

. If

\gamma \geq 1

and

\{\Lambda_j\}_{j\geq1}

is a positive sequence tending to infinity we prove that

\{\Omega_{\Lambda_j, \gamma}(\mathcal A)\}_{j\geq1}

is a bounded sequence, and hence contains a convergent subsequence. Under an additional assumption on

\mathcal A

we characterize the possible limits of such subsequences as minimizers of the perimeter among domains in

\mathcal A

of unit measure. For instance if

\mathcal A

is the set of all convex polygons with no more than

m

faces, then

\Omega_{\Lambda, \gamma}

converges, up to rotation and translation, to the regular

-gon.
Perturbations of continuum random Schrödinger operators with applications to Anderson orthogonality and the spectral shift function
Authors: Dietlein Adrian , Gebert Martin , Müller Peter
Published: March 2019

We study effects of a bounded and compactly supported perturbation on multidimensional continuum random Schrödinger operators in the region of complete localisation. Our main emphasis is on Anderson orthogonality for random Schrödinger operators. Among others, we prove that Anderson orthogonality does occur for Fermi energies in the region of complete localisation with a non-zero probability. This partially confirms recent non-rigorous findings [V. Khemani et al., Nature Phys. 11 (2015), 560–565]. The spectral shift function plays an important role in our analysis of Anderson orthogonality. We identify it with the index of the corresponding pair of spectral projections and explore the consequences thereof. All our results rely on the main technical estimate of this paper which guarantees separate exponential decay of the disorder-averaged Schatten

p

-norm of

\chi_{a}(f(H) - f(H^{\tau})) \chi_{b}

in

a

and

b

. Here,

H^{\tau}

is a perturbation of the random Schrödinger operator

H

,

\chi_{a}

is the multiplication operator corresponding to the indicator function of a unit cube centred about

a\in\mathbb R^{d}

, and

f

is in a suitable class of functions of bounded variation with distributional derivative supported in the region of complete localisation for

The BCS critical temperature in a weak homogeneous magnetic field
Authors: Frank Rupert L. , Hainzl Christian , Langmann Edwin
Published: March 2019

We show that, within a linear approximation of BCS theory, a weak homogeneous magnetic field lowers the critical temperature by an explicit constant times the field strength, up to higher order terms. This provides a rigorous derivation and generalization of results obtained in the physics literature fromWHH theory of the upper critical magnetic field. A new ingredient in our proof is a rigorous phase approximation to control the effects of the magnetic field.
On the decomposition principle and a Persson type theorem for general regular Dirichlet forms

We use the decomposition principle to derive a Persson type theorem for the corresponding Dirichlet forms. In particular our setting covers Laplace–Beltrami operators on Riemannian manifolds, and Dirichlet forms associated to

-stable processes in Euclidean space.
Spectral edge behavior for eventually monotone Jacobi and Verblunsky coefficients
Authors: Lukic Milivoje
Published: March 2019

We consider Jacobi matrices with eventually increasing sequences of diagonal and off-diagonal Jacobi parameters. We describe the asymptotic behavior of the subordinate solution at the top of the essential spectrum, and the asymptotic behavior of the spectral density at the top of the essential spectrum.

In particular, allowing on both diagonal and off-diagonal Jacobi parameters perturbations of the free case of the form

- \sum_{j=1}^J c_j n^{-\tau_j} + o(n^{-\tau_1-1})

with

0 < \tau_1 < \tau_2 < \dots < \tau_J

and

c_1 > 0

, we find the asymptotic behavior of the log of spectral density to order

O(\mathrm {log}(2-x))

as

x

approaches 2.

Apart from its intrinsic interest, the above results also allow us to describe the asymptotics of the spectral density for orthogonal polynomials on the unit circle with real-valued Verblunsky coefficients of the same form.
Peierls' substitution for low lying spectral energy windows
Authors: Cornean Horia , Helffer Bernard , Purice Radu
Published: March 2019

We consider a

2d

periodic magnetic Schrödinger operator perturbed by a weak magnetic field which slowly varies around a positive mean. In a previous paper we proved the appearance of a “Landau type” structure of spectral islands at the bottom of the spectrum, under the hypothesis that the lowest Bloch eigenvalue of the unperturbed operator remained simple on the whole Brillouin zone, even though its range may overlap with the range of the second eigenvalue. We also assumed that the first Bloch spectral projection was smooth and had a zero Chern number.

In this paper we extend our previous results to the only two remaining possibilities: either the first Bloch eigenvalue remains isolatedwhile its corresponding spectral projection has a non-zero Chern number, or the first two Bloch eigenvalues cross each other.

Published: March 2019

Procura-se discutir o que são os Direitos Econômicos, Sociais e Culturais (DESC), tanto na sua aplicação internacional quanto regional, com foco nos tratados internacionais, para demonstrar a vinculação de responsabilidades assumidas pelos Estados partes, fiscalizados por meio de mecanismos de controle internacionais e pelo controle de convencionalidade nacional. Em seguida, demonstra-se a natureza fundamental de tais direitos através de respostas às críticas quanto a sua força vinculante e exequibilidade. Fundamenta-se, através da pesquisa bibliográfica qualitativa, a análise doutrinária e econômica sobre os DESC por meio da Teoria das Capacidades de Amartya Sen, onde se discute a relação entre o social e o financeiramente possível, justificado pelo conceito de mínimo existencial. Por fim, faz-se uma relação entre realizações individuais, identidade e desenvolvimento social, através do diálogo público propiciado pelo aumento de liberdades, as quais são responsáveis por proporcionar capacidades para atingir os funcionamentos, as realizações.
O dever de cooperação nos contratos de venda internacional de mercadorias: pressupostos teóricos e repercussões práticas da cláusula geral da boa-fé objetiva para a aplicação da CISG
Authors: Prata de Carvalho Angelo Gamba
Published: March 2019

Objetivo do artigo: O presente trabalho tem por objetivo esclarecer e construir dogmaticamente, a partir da CISG e dos princípios UNIDROIT, o sentido e o conteúdo do dever de cooperação nos contratos internacionais de compra e venda de mercadorias.

Metodologia: A análise empreendida neste trabalho partiu de revisão da literatura relativa à CISG e ao emprego das cláusulas gerais no direito privado, bem como de análise jurisprudencial de precedentes brasileiros e estrangeiros.

Conclusões: A boa-fé a que alude a CISG necessariamente será a boa-fé objetiva, assim entendida como padrão normativamente esperado das partes para a promoção da lealdade de uma parte para com a outra e mesmo para com o mercado, de modo a manter a higidez do ambiente econômico em que se encontram.

Originalidade ou valor: O trabalho se destaca por atribuir à tarefa de interpretação dos contratos internacionais critério operacional consistente na aplicação da cláusula geral da boa-fé objetiva conforme desenvolvida pela doutrina do sistema romano-germânico, retirando de tal conceito aberto regras e diretrizes capazes de densificar a noção de cooperação presente na CISG e nos princípios UNIDROIT.

Palavras-chave: CISG; Direito Internacional Privado; Boa-fé objetiva.
A participação de Brasil e estados unidos na formulação das regras multilaterais do comércio agrícola
Authors: Thorstensen Vera , Daniele Rocha Gabriel Vivian , Mesquita Alebe Linhares
Published: March 2019

O presente artigo tem por objetivo analisar a participação do Brasil e dos Estados Unidos no estabelecimento das regras do comércio agrícola internacional sob o âmbito da Organização Mundial do Comércio. Por conseguinte, este artigo encontra-se dividido em três momentos distintos. Primeiramente, discorre-se sobre a regulação do comércio agrícola no sistema multilateral de comércio, desde o Acordo Geral de Tarifas e Comércio de 1947 até o Acordo sobre Agricultura e as mais recentes decisões ministeriais. Em seguida, analisa-se os posicionamentos do Brasil e dos Estados Unidos na negociação das regras que regem o comércio agrícola internacional sob o sistema multilateral do comércio. Por fim, considera-se uma nova agenda de negociação agrícola para o Brasil e os Estados Unidos. A metodologia adotada no desenvolvimento da pesquisa caracteriza-se como teórica, bibliográfica, descritiva e exploratória. Em conclusão, pode-se afirmar que apesar de Brasil e Estados Unidos serem notáveis produtores agrícolas, com alto nível de competitividade internacional, e sempre terem sido muito ativos nas negociações multilaterais sobre o tema, as iniciativas entre os dois países nessa área ainda são muito restritas. Dentre os temas com potencial para uma frutífera cooperação bilateral, o presente estudo identificou: a criação de um “grupo do grão”; a adoção de um acordo plurilateral em agricultura envolvendo os maiores exportadores agrícolas; e a instituição de uma “Organização Internacional da Soja”, nos moldes da Organização Internacional do Café.
A dimensão jurídica do imperialismo na (des)ordem global capitalista: uma análise com base na crítica marxista ao direito internacional e às relações político-econômicas de dominação e dependência
Authors: Delgado De David Thomaz , Oliveira da Silva Maria Beatriz , Mariano da Rocha Barcellos Terra Rosane Beatris
Published: March 2019

O advento do capitalismo na modernidade inaugura uma etapa de substanciais modificações no panorama mundial. Nesse contexto, relações assimétricas entre os Estados dão causa a uma ruptura dicotômica entre centro e periferia global. O imperialismo capitalista, síntese dessas relações, apresenta várias “dimensões” indivisíveis, como a política e a econômica. Por sua vez, uma análise do papel do Direito nas relações internacionais sugere que o imperialismo possui também uma dimensão jurídica que o ampara ou consubstancia. À vista disso, questiona-se: a partir de uma teoria marxista do Direito Internacional, bem como da consideração do imperialismo capitalista enquanto fenômeno multidimensional de dominação e dependência, como pode ser compreendida a dimensão jurídica do imperialismo? Para responder tal questão, emprega-se o método de abordagem materialista histórico-dialético, o método de procedimento histórico e a técnica de pesquisa bibliográfica. Assim, objetiva-se compreender a dimensão jurídica do imperialismo capitalista, por intermédio da crítica marxista ao Direito Internacional e à economia política internacional. Os resultados obtidos indicam que o conteúdo normativo do Direito Internacional é passível de mudança conforme a luta de classes e que, em razão disso, pode comprometer-se com o imperialismo ou assumir contornos não-hegemônicos. Ainda, apontam que a forma jurídica que fundamenta o Direito e seu ramo internacional é condição necessária para a manutenção e a reprodução das relações imperialistas em uma formação social capitalista global. A relevância desta pesquisa reside na atualização da crítica marxista ao Direito, aplicando-a ao ramo jurídico internacional, enquanto que a originalidade decorre da sua interdisciplinaridade e da metodologia empregada.

Abstract. Cold frontal passages usually promote quick removal of atmospheric pollutants over
North China (e.g. the Beijing–Tianjin–Hebei region). However, in the Yangtze River
Delta (YRD), cold fronts may bring air pollutants from the polluted North China Plain
(NCP), thereby deteriorating the air quality in the YRD. In this study, a cold frontal
passage and a subsequent stable weather event over YRD during 21–26 January 2015 was
investigated with in situ observations and Weather Research and Forecasting – Community
Multiscale Air Quality Modeling System simulations. Observations showed a burst of
PM2.5 pollution and an obvious southward motion of PM2.5 peaks on the afternoon
of 21 January, suggesting a strong inflow of highly polluted air masses to YRD by a cold
frontal passage. Model simulations revealed an existing warm and polluted air mass over
YRD ahead of the frontal zone, which climbed to the free troposphere along the frontal
surface as the cold front passed, increasing the PM2.5 concentration at high
altitudes. Strong north-westerly frontal airflow transported particles from the highly
polluted NCP to the YRD. As the frontal zone moved downstream of YRD, high pressure took
control over the YRD, which resulted in a synoptic subsidence that trapped PM2.5 in
the boundary layer. After the cold frontal episode, a uniform pressure field took control
over the YRD. Locally emitted PM2.5 started to accumulate under the weak winds and
stable atmosphere. Tagging of PM2.5 by geophysical regions showed that the
PM2.5 contribution from the YRD itself was 35 % and the contribution from the
NCP was 29 % during the cold frontal passage. However, under the subsequent stable
weather conditions, the PM2.5 contribution from the YRD increased to 61.5 % and
the contribution from the NCP decreased to 14.5 %. The results of this study indicate
that cold fronts are potential carriers of atmospheric pollutants when there are strong
air pollutant sources in upstream areas, which may deteriorate air quality in downstream
regions.
September Arctic sea ice minimum prediction – a skillful new statistical approach

Abstract. Sea ice in both polar regions is an important indicator of the
expression of global climate change and its polar amplification.
Consequently, broad interest exists on sea ice coverage, variability and
long-term change. However, its predictability is complex and it depends
strongly on different atmospheric and oceanic parameters. In order to
provide insights into the potential development of a monthly/seasonal signal
of sea ice evolution, we applied a robust statistical model based on
different oceanic and atmospheric parameters to calculate an estimate of the
September sea ice extent (SSIE) on a monthly timescale. Although previous
statistical attempts of monthly/seasonal SSIE forecasts show a relatively
reduced skill, when the trend is removed, we show here that the September
sea ice extent has a high predictive skill, up to 4 months ahead, based on
previous months' oceanic and atmospheric conditions. Our statistical model
skillfully captures the interannual variability of the SSIE and could
provide a valuable tool for identifying relevant regions and oceanic and
atmospheric parameters that are important for the sea ice development in the
Arctic and for detecting sensitive/critical regions in global coupled
climate models with a focus on sea ice formation.

Abstract. To bridge the gap between large-scale GCM (global climate model) outputs and
regional-scale climate requirements of hydrological models, a
spatiotemporally distributed downscaling model (STDDM) was developed. The
STDDM was done in three stages: (1) up-sampling grid-observations and GCM
simulations for spatially continuous finer grids, (2) creating the mapping
relationship between the observations and the simulations differently in
space and time, and (3) correcting the simulation and producing downscaled
data to a spatially continuous grid scale. We applied the STDDM to
precipitation downscaling in the Poyang Lake watershed using the MRI-CGCM3
(Meteorological Research Institute Coupled Ocean–Atmosphere General
Circulation Model 3), with an acceptable uncertainty of ≤ 4.9 %.
Then we created future precipitation changes from 1998 to 2100 (1998–2012 in
the historical scenario and 2013–2100 in the RCP8.5 scenario). The
precipitation changes increased heterogeneities in temporal and spatial
distribution under future climate warming. In terms of temporal patterns, the
wet season become wetter, while the dry season become drier. The frequency of
extreme precipitation increased, while that of the moderate precipitation
decreased. Total precipitation increased, while rainy days decreased. The
maximum continuous dry days and the maximum daily precipitation both
increased. In terms of spatial patterns, the dry area exhibited a drier
condition during the dry season, and the wet area exhibited a wetter
condition during the wet season. Analysis with temperature increment showed
precipitation changes can be significantly explained by climate warming, with
p<0.05 and R≥0.56. The precipitation changes indicated that the
downscaling method is reasonable, and the STDDM could be successfully applied
to the basin-scale region based on a GCM. The results implied an increasing
risk of floods and droughts under global warming, which were a reference for
water balance analysis and water resource planning.

MARKETING FARMACÊUTICO: RELAÇÃO DAS PUBLICIDADES TELEVISIVAS COM A AUTOMEDICAÇÃO
Authors: CARSONI Liana Maria Mazutti , JUNIOR Devanir Avigo
Published: March 2019

As indústrias farmacêuticas aplicam o marketing farmacêutico para dar publicidade aos medicamentos por elas comercializados e elevar o seu faturamento. No entanto, observa-se que a maioria das publicidades veiculadas em emissoras de televisão no Brasil apresenta algum tipo de infração legal. Com o objetivo de trazer ao conhecimento do profissional farmacêutico e demais profissionais da área da saúde tais ilegalidades, demonstrando como a publicidade pode se tornar um poderoso instrumento de indução a hábitos que elevam o consumo medicamentoso, afetando o tratamento terapêutico de maneira significativa, buscou-se uma revisão da literatura em um levantamento bibliográfico, trazendo informações sobre o tema central, fazendo uma análise quanto à adequação deste tipo de publicidade com a legislação vigente e seus reflexos ao público alvo. Esse trabalho trás uma análise da normatização do país, e se a mesma se mostra eficiente. E ainda, demonstra alguns dos impactos, sociais e jurídicos da publicidade farmacêutica. Por fim, constata-se que a legislação atual não contempla de maneira satisfatória a prática da promoção televisiva de medicamentos, de modo a permitir a sua banalização como uma simples mercadoria, através de anúncios tendenciosos que fomentam o seu uso de maneira irracional.
