The purpose of this paper is to analyze the climate changes in Pakistan, identify issues related to weather disasters and to revisit weather prediction approaches. The proposed approach is based on different algorithms and their comparisons with reference to past 5years (2010 - 2015) data on 12 attributes. A flow diagram is given that identifies steps included in the process. Results are obtained using WEKA 3.7.13 (latest version 2015). The KNN algorithm and memory-based reasoning algorithm shows the accuracy of predicting weather forecasts. The BPANN algorithm is used to analyze the data set along with KNN and memory-based reasoning algorithms. Decision tree shows the accuracy of predicting weather forecasts. The KNN is used with Bayesian approach in this research. Attributes used in this research shows significant relationship while many of those work as independent variables. Since, for weather prediction these attributes are very important, we used variant factors based on time and date. The KNN algorithm using Bayesian classifier provides accurate results compare with memory-based reasoning of Decision Tree and BPANN trainlm and trainbr.

Published: September 2018

Wireless Multimedia Sensor Network (WMSN) is a collection of the vast amount of different types of sensors like camera sensor, video and scalar sensors which are involved in retrieving multimedia data from the large environment. The real-time sending of video and audio content to the destination before a strict playout deadline has been necessary for multimedia environment. Otherwise, it will be dropped at the destination. In WMSN sending real time multimedia data with soft play deadlines is a challenging task to solve this challenge, routing protocols play an important role in WMSN. Routing demands of multimedia content of WMSNs need to be perfect routing protocols to optimize path selection and guarantee communication. This paper presents a performance comparison between two reactive routing protocols; namely AODV and DSR, with soft delay deadlines and efficient utilization of resources in WMSN. The objective is to assess the real-time behavior of these two protocols upon sending multimedia content. Here, we evaluate the performance with respect to the use of these matrices like latency, Average jitter, Average delay and throughput and factors includes are CBR and multimedia traffic with varying packet size and bandwidth. DSR perform better as compared to AODV routing protocol since it discovers the routes more efficiently. AODV is better in term of Jitter than DSR. NS-2 simulator tool used for the purpose of this comparison.

Published: September 2018

Internet has become a vital part of our lives. The number of Internet connected devices are increasing every day and approximate there will be 34 billion IoT devices by 2020. It is observed that security is very weak in these devices and can be easily compromised by hackers as some manufactures failed to implement basic security. Current devices use standards that are easy to implement and works for most forms of communications and storage. There is no such standard solution that will work on every device within the Internet of Things, because of the varied constraints between different devices; resulting in classifications within the Internet of Things. This study addresses security challenges in the Internet of Things (IoT); first will discuss the IoT evolution, architecture and its applications in industries. Further, classify and examine privacy threats, including survey, and pointing out the challenges that need to be overcome to ensure that the Internet of Things becomes a reality.

Published: September 2018

A fibroina da seda é um biopolímero natural proveniente de Bombyx mori L. (bicho da seda) que possui excelente estabilidade térmica e resistência mecânica. Parte deste biopolimero é rejeitada no processo industrial devido a escolha de casulos viáveis para a produção de seda de qualidade. O objetivo dessa pesquisa foi reaproveitar o biopolímero natural proveniente de B. mori para produzir sistemas, processados por casting, de misturas de poliamida 6 com nanotubo de carbono funcionalizado com carboxila e a fibroina. O filme polimérico foi obtido por casting, utilizando ácido fórmico como solvente. As propriedades físico-químicas foram analisadas por Espectroscopia no Infravermelho, análise termogravimétrica e ensaios de tração mecânica. Os resultados das análises reportaram o aumento na estabilidade térmica e mecãnica dos filmes com a presença de fibroina e MWNT nos compósitos de poliamida 6, tendo atingido um módulo de elasticidade de 4,0 GPa com 0,025% em massa de nanotubo no compósito. Assim, a incorporação da fibroína, extraída de casulos considerados defeituosos, em compósito com poliamida 6 e nanotubo de carbono funcionalizado com carboxila melhorou a estabilidade mecânica nestes sistemas quando comparado a poliamida 6 pura, formando um sistema com potencial uso como material de engenharia.
Habitudes d'utilisation des soins de santé chez les personnes ayant fait une surdose de drogues illicites : analyse descriptive

Published: September 2018

Introduction

La Colombie-Britannique (C.-B.) a déclaré un état d'urgence en santé publique
en avril 2016 en réaction à une augmentation rapide du nombre de décès par surdose. Une
meilleure compréhension de l'utilisation des soins de santé est nécessaire pour guider les
stratégies de prévention pour les personnes qui font une surdose de drogues illicites.

Méthodologie

La cohorte provinciale des victimes de surdoses comprend des données
administratives couplées sur l'utilisation des soins de santé par les personnes qui ont été
victimes d'une surdose de drogues illicites en Colombie-Britannique entre le 1er janvier
2015 et le 30 novembre 2016. Les cas de surdose ont été relevés à l'aide de données
provenant des services ambulanciers, des enquêtes des coroners, des appels aux centres
antipoison et des dossiers administratifs des hôpitaux, des services d'urgence et des
médecins. Au total, 10 455 cas de surdose ont été recensés et comparés à 52 275 témoins
appariés selon l'âge, le sexe et la zone de résidence en vue d'une analyse descriptive de
l'utilisation des soins de santé.

Résultats

Les deux tiers (66 %) des cas de surdose concernaient des hommes, et environ
la moitié (49 %) les 20 à 39 ans. Plus de la moitié des cas (54 %) se sont rendus au service
d'urgence, et environ le quart (26 %) ont été admis à l'hôpital au cours de l'année
précédant la surdose, comparativement à respectivement 17 % et 9 % des témoins.
Cependant, près d'un cinquième (19 %) des cas ont été enregistrés comme ayant quitté le
service d'urgence sans avoir été vus par le médecin ou contre son avis. Des proportions
élevées de cas (75 %) et de témoins (72 %) ont consulté un médecin en milieu communautaire.
La consommation de substances et des problèmes en santé mentale ont été les
diagnostics les plus courants chez les personnes qui ont fait une surdose.

Conclusion

Les personnes qui ont fait une surdose ont souvent eu accès au système de
soins de santé au cours de l'année précédant la surdose. Compte tenu de ces taux élevés
d'utilisation des soins de santé, on pourrait peut-être repérer les personnes à risque avant
qu'elles ne fassent de surdose et les aiguiller vers des programmes ciblés et des interventions
fondées sur des données probantes. Il est prévu d'utiliser la cohorte provinciale des
victimes de surdoses de la Colombie-Britannique pour déterminer les facteurs de risque
relatifs aux surdoses et aux décès par surdose.
Aperçu - Que peuvent nous révéler les données des ambulanciers paramédicaux sur la crise des opioïdes au Canada?

Published: September 2018

La nature de la crise des opioïdes au Canada nécessite des sources de données supplémentaires
aptes à dresser un portrait plus fidèle de l’épidémie, afin de fournir aux responsables
en santé publique et aux décideurs une base de données probantes solide. Les
données des ambulanciers paramédicaux sont un point d’accès aux collectivités où les
surdoses surviennent.
Les événements préhospitaliers et les circonstances entourant les surdoses d’opioïdes
offrent des occasions uniques de recueillir des données probantes pouvant contribuer à la
prévention, à la réduction des méfaits et aux efforts de promotion de la santé. À l’aide de
données extraites du Service paramédic d’Ottawa (SPO), cette étude de validation de principe
a démontré que les données d’intervention ambulancière paramédicale étaient utiles
pour obtenir des renseignements épidémiologiques en temps quasi réel (personne, heure
et lieu) sur l’épidémie d’opioïdes et pour évaluer les tendances ainsi que les possibilités
d’élaborer des déclencheurs d’alerte.
Entre janvier et juin 2017, le SPO a répondu à une moyenne de quatre appels liés aux
opioïdes par semaine. À chaque fois, 0,5 mg de naloxone ont en moyenne été administrés.
Pour la période à l’étude, les tendances linéaires montrent une faible augmentation
des appels, non significative (p = 0,18). Le volume d’appels a augmenté entre le 16 et le
29 avril 2017. Selon les médias locaux, ce pic dans les interventions ambulancières paramédicales
est attribuable à l’arrivée de fentanyl de qualité supérieure à Ottawa.
Avec une validation plus poussée, ces données paramédicales pourraient potentiellement
constituer une nouvelle source de données pour la surveillance des surdoses liées aux
opioïdes.
Aperçu - Suicides et intoxication aux opioïdes en Alberta (2000-2016)

Published: September 2018

Dans le cadre de la crise actuelle des opioïdes au Canada, il est important de s'intéresser
au rôle joué par l’intoxication aux opioïdes dans les décès par suicide et, plus particulièrement,
de déterminer si les tendances observées à cet égard sont similaires aux tendances
observées pour les décès accidentels. Dans cette analyse, on examine les caractéristiques
du suicide par intoxication aux opioïdes et la corrélation entre cette méthode et d’autres
moyens de suicide entre 2000 et 2016 en Alberta. La crise des opioïdes ne semble pas
avoir causé un nombre disproportionnellement élevé de suicides en Alberta. Les personnes
qui décèdent des suites d’une intoxication accidentelle aux opioïdes et celles qui
se suicident en s’intoxiquant avec des opioïdes constituent probablement des populations
différentes, ce qui nécessite des interventions préventives nuancées en matière de santé
publique.

Published: September 2018

The paper presents the yield results obtained in 2017 for the corn crop grown in the soil and climate conditions of Southern Romania (Calarasi county). The purpose of the research was to analyze the behavior and yield of a range of corn hybrids from different FAO groups: DKC 4590 (FAO 350), PP9911 (FAO 410) and Olt (FAO 430) under different soil tillage systems. The conventional tillage system applied was plowing at 20 and 30 cm, while scarifying at 30 and 40 cm and Tiger 3 MT at 20 and 30 cm were used for the minimum tillage system. The average yield of the three hybrids analyzed was 8,130.3 kg/ha in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding, while for the conventional tillage system without mechanical weeding the yield was 7,682.2 kg/ha. The minimum tillage variants (scarifying and Tiger 3 MT) recorded an average yield of 6,746.4 kg/ha when mechanical weeding was applied and 6,474.9 kg/ha for the variants without mechanical weeding. Regarding the degree of weeding by tillage system, in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding the number of weeds was 4.2 plants/m2 and 9.3 plants/m2 for the variants without mechanical weeding. The minimum tillage variants (scarifying and Tiger 3 MT) recorded 12.8 weeds/m2 when mechanical weeding was applied and 16.2 weeds/m2 for the variants without mechanical weeding.

Published: September 2018

In the last years sunflower become one of the most important crops in Romania. The most of the surface cultivated with sunflower from our country is located in south and south-east and, in many cases, sunflower is cultivated after maize. As result the attack of the maize leaf weevil (Tanymecus dilaticollis Gyll) at sunflower plants has increasing. The attack is dangerous when sunflower plants are in first vegetation stages (BBCH 10-BBCH 14). Similar with maize crop, sunflower seeds treatment with neonicotinoids were generalized after 2007. As result of the EU directive 485/2013, no active ingredients remain available for sunflower seeds treatment, against T. dilaticollis, in Romania. The researches from the last years were orientated for finding of the possible alternatives for seed treatments, in eventuality of permanent ban of neonicotinoid insecticides, after 2018. Because of the variability of climatic conditions from the field, during spring period, researches concerning effectiveness testing of sunflower seed treatments, in green house conditions, using high pest pressure is a good method to evaluate influence of the different active ingredients to control T. dilaticollis adults. In this experiment it has tested three doses of cyantraniliprole active ingredient (7.5, 10.0 and 12.5 l/to) and three neonicothinoid active ingredients (imidacloprid, clothianidin, thiamethoxam). Sunflower seeds were placed in plastic pots. After plants emergence the insects were added in pots. At each pot it has added 20 adult insects, collected from the field. Each day, it has recorded insect mortality. At 8 days from the start of the experiment, it has assessed attack intensity of the adult insects on sunflower plants. The attack was evaluated using a scale from 1 (plant not attacked) to 9 (plant complete destroyed). In conditions of high pest pressure (4 insects/plant) the attack intensity of T. dilaticollis at sunflower plants was ranged from 3.35 in case of variant treated with clothianidin and 8.50 in case of untreated plants. Lower attack intensity of the pest at sunflower plants it has registered in case of variants treated with imidacloprid and thiamethoxam (I=3.58 and 3.50). Plants emerged from the untreated seeds were destroyed by the insects, at 8 days from the start of the experiment.
Effects of Combined Application of Bradyrhizobium Japonicum and Pseudomonas Putida on Nutrients and Water Contents of Soybean in Relation to Soil Moisture Regime
Authors: Rotaru Vladimir
Published: September 2018

Plant growth promoting rhizobacteria (PGPR) are of growing interest for their potential role in improving soil fertility and enhancing crops productivity and nutrients contents. In order to assess the impact of PGPR on nutrients contents of soybean, a greenhouse experiment was carried out with Bradyrhizobium japonicum applied alone or in combination with Pseudomonas putida in conjunction with fertilization of P or manure. Two soil moisture regimes were installed: 70% of whole holding capacity (WHC) as control and 35% WHC as moderate water stress. The water deficit was imposed at the flowering stage for 12 days. Plants cultivated under P insufficiency and drought exhibited lower physiological parameters in treatment with single inoculation of B. japonicum than combined application of two rhizobacteria. The results showed that the combined application of rhizobacteria enhanced the N and P contents of soybean regarding of soil water conditions. The integrated use of rhizobacteria improved the relative water content of soybean. Their influence was more pronounced under P deficiency and manure fertilization of plants especially under no stress water conditions. Hence, combined application of B. japonicum and P. putida has a potential to improve nutrition and growth of soybean under normal soil moisture as well as under moderate drought.

Published: September 2018

Recent research reports that enzymes accumulated in soil participate in the cycles of elements and contribute to soil fertility. The purpose of this paper is to determine the enzymatic activity and the humus content in the materials from waste heap in order to assess their fertility and to establish possible re-cultivation technologies. The investigations were carried out on materials from the Pesteana North waste heap. In order to achieve this, the activity of catalase, invertase, urease and phosphatase activity was determined in different plots of the heap during the summer and as a control the zonal soil was used. Enzymatic activities were colorimetric assay using appropriate substrates. The obtained results show a large variation in the values of the determined enzymatic activities. In all investigated plots, all enzymes are found to be lower than those determined for the zonal soil. A strong positive correlation is observed between enzymatic activities of catalase and invertase and the accumulation of humus which demonstrates that enzymatic activities has a useful tool for studying the evolution of heap materials to agricultural soils.

Published: September 2018

Colibacillosis in poultry is relating with the colonisation with so called Avian Pathogen E. coli (APEC) strains. It is already known that usually in the APEC isolates are present at least 13 virulence-associated genes. We selected 12 non-repetitive E. coli isolates from different Romanian poultry outbreaks. Isolates have been evaluated for the presence of the virulence-associated genes, iroN and iucC. The DNA extraction was made using QIAamp cador Pathogen Mini Kit (Qiagen). The amplification protocol was: a cycle of denaturation at 94°C for 5 min followed by 35 cycles of 94°C for 30 s, 63°C for 45 s and 72°C for 105 s, and a cycle of 72°C for 7 min. Both virulence-associated genes were identified in 83.33% (11/12) isolates. In two APEC isolates, only one gene was identified, iroN or iucC, respectively. According to these preliminary results it could be assumed that iroN and iucC genes are independently expressing their virulence.

The Relationship between Current Account Deficits and Growth in Montenegro: ARDL Bounds Testing Approach
Authors: Özer Mustafa , Žugić Jovana , Tomaš-Miskin Sonja
Published: September 2018

In this study, we investigate the relationship between current account deficits and growth in Montenegro by applying the bounds testing (ARDL) approach to co-integration for the period from the third quarter of 2011 to the last quarter of 2016. The bounds tests suggest that the variables of interest are bound together in the long run when growth is the dependent variable. The results also confirm a bidirectional long run and short run causal relationship between current account deficits and growth.

The short run results mostly indicate a negative relationship between changes in the current account deficit GDP ratio and the GDP growth rate. This means that any increase of the value of independent variable (current account deficit GDP ratio) will result in decrease of the rate of GDP growth and vice versa.

The long-run effect of the current account deficit to GDP ratio on GDP growth is positive. The constant (β0) is positive but also the (β1), meaning that with the increase of CAD GDP ratio of 1 measuring unit, the GDP growth rate would grow by 0,5459. This positive and tight correlation could be explained by overlapping structure of the constituents of CAD and the drivers of GDP growth (such as tourism, energy sector, agriculture etc.).

The results offer new perspectives and insights for new policy aiming for sustainable economic growth of Montenegro.

SThe active disturbance rejection control (ADRC) exhibits strong robustness and adaptability in the presence of strong interference of a large class of uncertain systems. In order to better control the water level of the auxiliary boiler drum, this paper applies the ADRC to improve its control precision, robustness and timeliness. Firstly, the change of drum water level in a large oil tanker auxiliary boiler is analyzed and the dynamic equation is established. After the mathematic changes, the dynamic equation is transformed into a two-order system. Aiming at the characteristics of nonlinear, time-varying and strong disturbance of the boiler water level control system in marine auxiliary boiler, studying the ADRC that includes tracking differentiator (TD), extended state observer (ESO), nonlinear feedback (NLSEF) and disturbance compensation of four parts. The establishment of two kinds of two-order ADRC controller to control the drum level. Through the theoretical analysis and simulation experiment test, and comparing with the cascade control strategy, the experimental results show that the active disturbance rejection controller satisfies the steady state response index of the system, and has good timeliness and accuracy to the control of water level of the drum.

Authors: Dong Liang-xiong , Shi Yi-ran , Wang Shao-hua
Published: September 2018

The anti-impact ability of shafting affects stability and security of the ship power transmission directly. Moreover, it also cannot be ignored that the rub-impact loads have influence on the torsion vibration of ship shafting. In order to solve the problem of engineering application of reliability assessment under rub-impact loads, a test rig with rubbing generator is established. By carrying out the integrative analysis, the torsional vibration characteristics, such as vibration amplitude and orbit of axle center under the rub impact load are studied. According to the rub-impact conditions obtained through numerical simulation, the experimental verification is carried out on the test rig with rubbing generator. The results show that it is not obvious the influence of rub-impact loads upon the shafting torsion vibration except in special working conditions, that can be simulated by the rubbing generator. The maximum amplitude of torsional vibration is influenced by the radial rigidity as well as the friction coefficient of rubbing body, and the degree of influence is difference under conditions of continuous rubbing and serious rubbing. By adjusting the rigidity of stern bearing, the influence of rub-impact upon shafting can be weaken, which provides a theoretical reference for the safety evaluation of ship shafting.

Published: September 2018

The study of the flow characteristics of the solid-fluid two phase flow in the cutter suction dredger is very important for exploring the slurry formation mechanism and optimizing the operational parameters. In this study, standard k-ε model and Multiple Reference Frame are applied to numerically simulate flow field in and around the cutting system, then with the steady convergent result of the simulation as the initial condition, Discrete Phase Mode is used to solve the particle motion equation by fully coupling the continuous phase and the particles. The influence of suction flow velocity and cutter’s rotating speed on particles suction are analyzed, and effectively suctioned particles numbers are also quantitatively studied. The simulation result shows that the DPM model is able to simulate the movement of particles in and around the cutter suction dredger’s cutting system, in the fluid flow filed velocity vector and pressure distribution on different planes show different characteristics, and under higher suction velocity and lower cutter rotating speed more particles are suctioned into the suction inlet. The results can help better understand flow characteristics of solid-fluid 2-phase-flow of cutter suction dredger’s cutting system, and provide theoretical support for relative system design and operational parameters optimization.

This paper summarizes results of a theoretical analysis of syntactic behavior of Czech light verb constructions and their verification in the linguistic annotation of a large amount of these constructions. The concept of LVCs is based on the observation that nouns denoting actions, states, or properties have a strong tendency to select semantically underspecified verbs, which leads to a specific rearrangement of valency complementations of both nouns and verbs in the syntactic structure. On the basis of the description of deep and surface syntactic properties of LVCs, a formal model of their lexicographic representation is proposed here. In addition, the resulting data annotation, capturing almost 1,500 LVCs, is described in detail. This annotation has been integrated in a new version of the VALLEX lexicon, release 3.5.
Does Reit offer a Better Risk and Return Contour to the New Zealand Residential Property Investors?
Authors: Chong Fennee
Published: September 2018

New Zealanders’ overwhelming favour of residential property investment has resulted in residential properties being overvalued with a house-price-to-income multiple equals to 5.9 for the country and 10 for its largest city – Auckland. With the deterioration in housing affordability; currently ranked the fourth worst in the world for Auckland (the largest city in New Zealand), investing directly in residential property become riskier. Under this scenario, a more passive property investment option such as REIT could be more viable. The objective of the paper is to assess whether REIT could offer a better risk and return contour then direct residential property option to potential property investors in New Zealand. Empirical findings from this study show that there is a significant difference between the rates of return of these two types of property investment options. Further analysis using Treynor ratio indicates that investing in REITs generated a higher return on a risk-adjusted basis. This finding has implications for investors looking for a more affordable and liquid way to tap into the property asset class.
A Time Series Analysis of the Nexus Between Macroeconomic Fundamentals and Stock Prices in Nigeria
Authors: Ditimi Amassoma , Ifeoluwa Bolarinwa
Published: September 2018

Since macroeconomic fundamentals have been found to play a vital role for changes in the economy of a country. Consequently, the onus is on the appropriate regulatory authorities to take measures in making amendments in these policies to put the economy on the right development track. The aim of this study is to use time series analysis to empirically showcase the nexus between macroeconomic fundamentals and stock prices in Nigeria. The method used for this study was the Co-integration test and the EGARCH technique to estimate the possible influence of the selected macroeconomic fundamentals on stock prices. Volatility was captured by using quarterly data and estimated using GARCH (1,1) respectively. The study found there is a positive relationship between macroeconomic factors and stock prices in Nigeria. Therefore, the study recommends that the Federal authority should put in place policy measures that will enable the exchange rate to be relatively stabilized. This is because empirical evidence from studies has shown that exchange rate affects stock market prices. In addition, the government authority should ensure an enabling environment that would build the mindset of institutional investors in the Nigerian stock market due to the existence of information asymmetry problems among potential investors.
Measuring Firm Performance: Testing a Proposed Model
Authors: Herciu Mihaela , Șerban Radu Alexandru
Published: September 2018

Firm performance is a very complex and exhaustive concept. It can be related to many factors: starting with variables from balance sheet, income statement or cash-flow statement, continuing with research and development expenses or IT competences, and last but not least with intangible assets like human capital, goodwill, or brand value. The purpose of the present paper is to develop and test a model in order to measure firm performance by considering US companies that are ranked into the Global Fortune 500. In this study we used control variables (assets growth rate, net income growth rate and revenue growth rate) and depended variables – return on assets (ROA), debt to equity, research and development expenses to total operating expenses, environment, social and governance rating, Tobin‘s q – to measure firm performance. The article‘s findings suggest that when analyzing the firm performance much more factors must be considered.
Government Ownership in Listed Firms Around the World
Authors: Liu Kerry
Published: September 2018

Based on the first of its kind large-scale research on worldwide government ownership from 47 countries, the results show that government owners like to be the largest blockholders; if government is the largest blockholder, the size of its ownership is also quite big. Government ownership is mostly distributed in banks, infrastructure and public utility companies, and strategic manufacturing companies. While there are various theoretical arguments on the size and industry distribution of government ownership, this study provides first-ever empirical evidence. In sum, this paper contributes significantly and originally to our understanding on government ownership, and lay out further directions for future research on the complicated corporate governance issues of government ownership.

Esta contribución analiza esquemáticamente la regulación de las declaraciones responsables y de las comunicaciones que contiene el Proyecto de Ley del procedimiento administrativo común de las administraciones públicas (I) y realiza una valoración crítica de la misma (II). En particular, se subrayan las deficiencias del régimen de control (II.A); se critica la posible supresión de las comunicaciones con potestad de veto (II.B); se destacan las carencias que se advierten (II.C); y se cuestiona que una ley de procedimiento administrativo sea la sede idónea para regular la materia (II.D).

A DESCONSIDERAÇÃO DA PERSONALIDADE JURÍDICA NOÇÕES GERAIS E QUESTÕES CONTROVERTIDAS À LUZ DA DOUTRINA E DA JURISPRUDÊNCIA
Authors: Boeira Alex Perozzo
Published: September 2018

A personalização de entes coletivos propiciou a individualização patrimonial e a afetação dos bens e direitos da pessoa jurídica às obrigações por ela assumidas. A utilização da pessoa jurídica permitiu, assim, o desenvolvimento da atividade econômica, incrementando sobremaneira a produção de bens e a circulação de riqueza. Por meio do instituto, confere-se um âmbito de proteção patrimonial significativo – ainda que não absoluto –, que encontra no acervo do ente moral a limitação das possíveis perdas decorrentes do exercício da atividade lucrativa. O aparato jurídico decorrente da personalização, todavia, não pode dar guarida a condutas marcadas por abuso de direito, fraude, confusão patrimonial – entre outras atuações ilícitas – que causem prejuízo aos interesses legítimos de credores. Nesse panorama, a teoria da desconsideração da personalidade jurídica é tecida com o propósito de corrigir o uso distorcido da pessoa jurídica em desconformidade com os fins de sua criação, permitindo, então, o acesso aos bens dos sócios envolvidos na prática de atos ilegais (em sentido amplo). A matéria veio a ser contemplada no ordenamento jurídico brasileiro, de maneira inovadora, com o CDC, repetindo-se, com maiores ou menores alterações de conteúdo, em outras disposições legislativas que lhe seguiram. Independentemente das diversas questões controversas e feições doutrinárias e jurisprudenciais acerca da desconsideração da personalidade jurídica, o fato é que a superação da limitação patrimonial do ente coletivo mantém a higidez do sistema e tutela a própria razão de ser da pessoa jurídica.
PANORAMA SOBRE O CONTROLE DE CONSTITUCIONALIDADE DE LEIS E ATOS NORMATIVOS NO BRASIL
Authors: Santos Daniel Guarnetti
Published: September 2018

O objeto do presente estudo é propiciar uma visão sobre o controle de constitucionalidade de leis e atos normativos no Brasil para proteção da norma fundamental, desde a primeira Constituição “Imperial” de 1824 até a atual de 1988, com a análise das emendas constitucionais e legislação correlata.  Para tanto, cotejou-se o controle brasileiro com o direito comparado dos principais modelos mundiais existentes, em especial o norte-americano, o austríaco e o francês, apontando-se a influência desses modelos sobre o nosso sistema de controle de constitucionalidade que assimilou aspectos de ordenamentos jurídicos distintos para a construção de uma estrutura própria de controle, um sistema híbrido. Também buscou-se a análise dos requisitos de constitucionalidade das espécies normativas, dando-se ênfase à importância e necessidade do controle de constitucionalidade em razão da supremacia constitucional, abarcando-se também as espécies de controle com suas peculiares características.
