Authors: Dipierro Serena , Pinamonti Andrea , Valdinoci Enrico
Published: June 2018

We present a geometric formula of Poincaré type, which is inspired by a classical work of Sternberg and Zumbrun, and we provide a classification result
of stable solutions of linear elliptic problems with nonlinear Robin conditions on Riemannian manifolds with nonnegative Ricci curvature.
The result obtained here is a refinement of a result recently established by Bandle, Mastrolia, Monticelli and Punzo.
Is the GDPR and Its Right to Data Portability a Major Enabler of Citizen Science?
Authors: Quinn Paul
Published: June 2018

Citizen science is an emerging trend with an ever greater number of adherents. It involves the collection and contribution of large amounts of data by private individuals for scientific research. Often such data will concern the individuals themselves and will be collected through processes of self monitoring. This phenomenon has been greatly influenced by the Internet of Things (IoT) and the connectivity of a wide range monitoring devices through the internet. In collecting such data use will often be made of the services of various commercial organisations, for example that offer cloud storage services. The possibility of data portability is extremely important in citizen science as it allows individuals (or data subjects) to be able move their data from one source to another (i. e. to new areas of scientific research). This article explores the limits and possibilities that legal rights to data portability offer, in particular the new right as outlined by the European Union’s General Data Protection Regulation. In doing so this article will look at where this right (and how it operates in the international legal context) is able to facilitate the phenomenon of citizen science.
Compressive Wave Propagation in Highly Ordered Granular Media Based on DEM
Authors: Wang Jiao , Chu Xihua
Published: June 2018

In this study, we investigated the propagation of the compressive waves in twp-dimensional highly ordered particle assemblies with different material properties and confining stresses. We focused on the attenuation of velocity amplitude, wave speed and energy dispersion behaviors. The mechanisms of wave propagation through specimens containing inclusions that show different horizontal angles were simulated. The peak velocities change exponentially as a function of time along the wave propagation direction. Energy dispersion exhibits an increasing trend as the angle increases. Then the effects of material parameter on wave propagation speed and the confining stress with the dispersion relations are determined. Finally, the shape of wavefront is studied to show the propagation of stress wave. It is linked to the distribution of equivalent strain. The outer contours of wavefront and strain distribution have the same shape.
Restricted Stock Discounts: An Empirical Analysis
Authors: McConaughy Daniel L. , Hussein Monica , Dow James P.
Published: June 2018

Examining 416 transactions over the 1996 to 2013 time period, we find that size, stock price volatility, block size, price-to-revenue, and EBITDA margin are significantly related to restricted stock discounts. We do not find registration rights or the initial holding period to be statistically significantly related to discounts. Our results suggest that simple correlations or sorting of discounts by various criteria do not capture what factors are statistically significantly related to restricted stock discounts in the complex world of private placement deals.
The diachrony of East Asian prosodic templates
Authors: Salmons Joseph , Zhuang Huibin
Published: June 2018

Typical words in some East Asian languages, including Chinese, have reduced historically from disyllabic (CV·CV(C)) to monosyllabic (C(C)V(C)) and then open monosyllables (CV). More recently, in some of those languages, many monosyllabic CV forms again appear as disyllabic (CV·CV). The former developments result from a variety of apparently unconnected segmental changes. In the latter, they often reflect morphological innovations, like compounding and affixation. That is, apparently disparate segmental phonological processes reduced monosyllabic word templates and apparently disparate morphological and phonological processes have created new disyllables, which can all be captured in terms of preferred prosodic templates. We integrate these areal and genetic patterns into a growing literature on prosodic templates in diachrony, expanding the set of languages and patterns. That body of work has focused on sound changes that bring words into alignment with templates while our cases studies also involve clear changes in the templatic structures themselves. Finally, the patterns reviewed here resemble cycles of prosodic change, driven by tensions between reduction and minimal word constraints; we suggest that these phenomena show ‘bare’ prosodic cyclicity without the grammatical or functional ramifications of familiar cycles of change.
Factors Associated with the Number of Substance Abuse Nonprofits in the U.S. States: Focusing on Medicaid Expansion, Certificate of Need, and Ownership
Authors: Noh Shihyun , Brown Catherine H.
Published: June 2018

The Affordable Care Act improved substance abuse service coverage and increased demand for these services. Presumably, these changes also influenced the number of substance abuse nonprofits in states. State decisions for Medicaid expansion have the potential to influence nonprofits' decisions to establish new facilities, increasing the demand for these services. In addition, Certificate of Need (CON), that is, state regulation of new health services and facilities, can affect nonprofits' responses to increased demand for substance abuse services. This study provides evidence that the number of nonprofit substance abuse facilities is negatively associated with state decisions to expand Medicaid and state regulation of new health services and facilities. However, in states with both Medicaid expansion and CON, the number of nonprofit substance abuse facilities tended to increase. In addition, evidence suggests that both nonprofit and for-profit substance abuse facilities are negatively influenced by Medicaid expansion and CON, but positively influenced by the interaction of Medicaid expansion and CON, government spending, racial diversity, median income, and uninsured rates.
Numerical investigation of nonlinear mechanical and constitutive effects on piezoelectric vibration-based energy harvesting
Authors: Cellular Ana Carolina , da Silva Monteiro Luciana L. , Savi Marcelo A.
Published: June 2018

Vibration-based energy harvesting has the main objective to convert available environmental mechanical energy into electrical energy. Piezoelectric materials are usually employed to promote the mechanical-electrical conversion. This work deals with a numerical investigation that analyzes the influence of nonlinear effects in piezoelectric vibration-based energy harvesting. Duffing-type oscillator that can be either monostable or bistable represents mechanical nonlinearities. A quadratic constitutive electro-mechanical coupling model represents piezoelectric nonlinearities. The system performance is evaluated for different system characteristics being monitored by the input and the generated power. Numerical simulations are carried out exploring dynamical behavior of energy harvesting system evaluating different kinds of responses, including periodic and chaotic regimes.
VUV Dissociative Photoionization of Quinoline in the 7–26 eV Photon Energy Range
Authors: Leach Sydney , Jochims Hans-Werner , Baumgärtel Helmut , Champion Norbert
Published: June 2018

The dissociative photoionization of quinoline was studied by photoionization mass spectrometry and ion yield measurements over a synchrotron photon excitation energy range 7–26 eV. The ionic and neutral products were identified with the aid of thermochemical calculations that, in some cases, led to deeper understanding of photodissociation pathways and the determination of upper limits of heats of formation of ionic and neutral dissociation products. A detailed comparison between the 20 eV photon excitation and 70 eV electron impact mass spectra, coupled with estimation of thermochemical appearance energies, leads to assignment of the dissociative ionization cation and neutral products for each detected ion. Reaction schemes for formation of these products are proposed in a number of cases. Ion intensities in the photon and electron impact mass spectra were used to consider extending a rule of charge retention in simple bond cleavage to more complex cases of dissociative ionization.

La comunicación en el tercer sector: el caso vallisoletano
Authors: Gómez Nieto Begoña , Soria Ibáñez María del Mar , Concejo Ulloa Beatriz
Published: June 2018

El Tercer Sector (TS) nace de la necesidad de generar un nuevo agente entre el sector público y el privado, y que por lo tanto represente a la ciudadanía. En España, la historia de las ONG demuestra que han sido organizaciones ligadas al poder público, desde su introducción como entidades asistencialistas tras la guerra civil. El objetivo de este trabajo, es realizar un análisis exhaustivo de la comunicación del Tercer Sector de modo general, y en particular, en la ciudad de Valladolid. Se desarrolla un profundo análisis del uso de la comunicación que hacen las entidades locales. Como metodología se ha empleado la técnica de investigación cuantitativa: cuestionario. La técnica permite obtener inferencias sobre la imagen que tienen las organizaciones no lucrativas de Valladolid frente a la ciudadanía. Entre los resultados destacamos que la principal fuente de financiación procede del ámbito público, por lo que persiste el modelo tradicional de gestión presupuestaria que siguen los organismos del Tercer Sector en España. Además, las entidades disponen de más voluntarios que trabajadores y utilizan las nuevas tecnologías para contactar con su público, aunque la ciudadanía encuestada manifiesta que no es receptora de los mensajes emitidos por las ONG, y consideran que no gestionan eficazmente su comunicación.
Estudio en cognición social: el vestuario y su vinculación como elemento de análisis en la comunicación no verbal
Authors: Rodríguez Jaime Jonathan
Published: June 2018

El objetivo del presente artículo es dilucidar si el vestuario debe ser un elemento de análisis en la comunicación no verbal (CNV), dado que en la actualidad existe una polarización académica, por un lado, quienes lo incorporan en el estudio de la comunicación y por otro, un grueso de autores que no lo contemplan, así las cosas, se realizó un estudio hermenéutico como método de la ontología elemental, por ello, esta investigación aporta criterios para crear un marco teórico de la CNV y del vestuario como sub-categoría, pues, al examinar estudios experimentales y revisar la doctrina científica, se encuentra que el vestuario: a) es un signo no lingüístico que envía al menos 19 mensajes diferentes, b) cumple con todos los elementos estructurales para que exista CNV c) está presente como mecanismo de expresión en otras especies d) apoya al sistema verbal ejecutando 5 funciones. Estos resultados sientan las bases para continuar con investigaciones experimentales, para que de esa manera, se puedan explorar otros aspectos del vestuario implicados en la cognición social. Adicionalmente, se concluye que es deber prioritario de la comunidad científica, acoger una clasificación uniforme, en orden a permitir el avance teórico de estos elementos a nivel mundial y a través de un mismo lenguaje, de lo contrario, las ciencias comunicativas, en especial en el ámbito de la CNV, seguirán adoleciendo de múltiples concepciones contrapuestas o imprecisas, por último, se propone la sigla (FV) para denominar todo factor o asunto devenido del vestuario como elemento de expresión no verbal.
Atrial Arrhythmias Including Atrial Fibrillation in Congenital Heart Disease: Mechanisms, Substrate Identification and Interventional Approaches
Authors: Shinbane Jerold S. , Chang Philip M.
Published: June 2018

Atrial arrhythmias, including atrial fibrillation, in the setting of congenital heart disease (CHD) are epidemiologically and mechanistically different from those encountered in the general population. These arrhythmias occur at younger ages in patients with CHD, and are frequently degenerative and progressive. The epidemiology, incidence, and prevalence of the spectrum of atrial arrhythmias, including atrial fibrillation, vary according to the specific CHD type, prior treatment, and residual and ongoing structural and functional sequelae. The combined impact of incisional scars, abnormal hemodynamics, atrial chamber dilatation, and increases in atrial wall thickness and distribution of fibrosis results in a highly dynamic and continuously changing atrial substrate that is highly predisposed to arrhythmias. Given the multiple substrates, individualized therapeutic plans can include pharmacologic therapy, catheter-based ablation, and surgical therapies performed concomitantly with primary surgical intervention for hemodynamically significant sequelae of CHD. Advanced imaging with CT or MRI can provide valuable information for decision making and procedural planning. Application of novel therapeutic technologies and pharmacologic agents necessitates special considerations when applied to the CHD population and requires greater study in specific subsets of CHD patients.
GENETICS IN ENDOCRINOLOGY: Genetic diagnosis of endocrine diseases by NGS: novel scenarios and unpredictable results and risks
Authors: Persani Luca , de Filippis Tiziana , Colombo Carla , Gentilini Davide
Published: June 2018

The technological advancements in genetics produced a profound impact on the research and diagnostics of non-communicable diseases. The availability of next-generation sequencing (NGS) allowed the identification of novel candidate genes but also an in-depth modification of the understanding of the architecture of several endocrine diseases. Several different NGS approaches are available allowing the sequencing of several regions of interest or the whole exome or genome (WGS, WES or targeted NGS), with highly variable costs, potentials and limitations that should be clearly known before designing the experiment. Here, we illustrate the NGS scenario, describe the advantages and limitations of the different protocols and review some of the NGS results obtained in different endocrine conditions. We finally give insights on the terminology and requirements for the implementation of NGS in research and diagnostic labs.
Der zivilprozessuale Nachweis eines Kartellrechtsverstoßes nach vorausgegangener Verpflichtungszusagenentscheidung
Authors: Thomas Stefan
Published: June 2018

Das Kartellschadensersatzrecht der EU-Richtlinie und der beiden letzten GWB-Novellen ist geprägt vom Paradigma der Follow-on-Klage nach Erlass einer Abstellungs- oder Bußgeldentscheidung. Sinnbild hierfür ist die gesetzlich angeordnete Feststellungswirkung in § 33b GWB (§ 33 Abs. 4 GWB a. F.). Kartellschadensersatzansprüche sind indes auch ohne vorherige behördliche Feststellung eines Verstoßes möglich, für die § 33b GWB als Beweiserleichterung dann aber ausscheidet. Es können hier ggf. nur die allgemeinen Vermutungs- und Anscheinsbeweise bezüglich des Schadens Anwendung finden, etwa § 33a Abs. 2 GWB oder § 33c Abs. 2 GWB, die u. a. voraussetzen, dass zunächst ein Kartellrechtsverstoß im Zivilprozess bewiesen wurde. Fraglich ist, wie es sich mit Blick auf den Beweis des Verstoßes verhält, wenn die Behörde zuvor eine Verpflichtungszusagenentscheidung nach Art. 9 VO 1/2003 bzw. § 32b GWB erlassen hat. Einerseits hat die Behörde in diesen Fällen erste Ermittlungen durchgeführt, andererseits fehlt es bei dieser Entscheidungsform an der Feststellung eines Verstoßes. Der EuGH hat vor diesem Hintergrund unlängst in seinem „Gasorba“-Urteil angemerkt, dass einer Verpflichtungszusagenentscheidung der Kommission in einem späteren Kartellzivilverfahren die Bedeutung eines „Indizes“ bzw. „Anfangsbeweises“ zukomme. Da der Gerichtshof aber keine weitergehenden Erläuterungen zu diesen Wirkungen gemacht hat und da überdies auch die EU-Kartellschadensersatzrichtlinie zu diesem Problem schweigt, geht der vorliegende Beitrag der Frage nach, welche Bedeutung eine Verpflichtungszusagenentscheidung für den Nachweis eines Verstoßes in einem nationalen Kartellschadensersatzprozess haben kann.

Authors: Brige Pauline , Hery Géraldine , Chopinet Sophie , Palen Anaïs , Azoulay Daniel , Gregoire Emilie
Published: June 2018

Background & Aims: The main restriction in the development of adult-adult Living Donor Liver Transplantation (LDLT) is the risk of morbidity and mortality for donors, which raises ethical questions. The objectives of this study are to review published studies dealing with morbidity and mortality in LDLT and to identify the proposed management and strategies for preventing donor mortality and morbidity in LDLT.Methods: The Medline database was searched from 2000 to 2017 using the MeSH terms “liver transplantation” and “morbidity” or “mortality” in combination with keywords “living donor liver transplantation”.Results: Among the 382 articles obtained, 43 articles were relevant for morbidity, 15 for mortality and 6 for both morbidity and mortality. Twenty-three papers reported donor deaths. The major cause of death was sepsis (30%). Morbidity ranged from 10% to 78.3% depending on the studies.Conclusions: The living donors’ morbidity and mortality is high, currently representing the main restriction in the development of LDLT. Some promising techniques, such as the donor portal vein flow modulation could lead to the further development of LDLT.
European cities continue to grow greener
Authors: Connolly Louise , Campion Louise , Rudden Patrick
Published: June 2018

Two-thirds of Europeans currently live in cities, predicted to rise to 80% by 2050. People choose to live in increasingly dense urban areas to gain better education and employment. However, urban living brings a range of environmental challenges and civil engineers need to provide solutions. The European Commission initiated the European Green Capital Award in 2008 to reward cities for environmental performance, sustainability plans and acting as a role model for other cities. This paper describes notable civil engineering features of four of the more recent winning cities: Copenhagen in Denmark, Essen in Germany, Nijmegen in the Netherlands and Oslo in Norway.
Investigation of construction techniques used for the foundation of the Taj Mahal in India
Authors: Sharma Avichal , Yang Jin , Parke Michael , Tan Fabian
Published: June 2018

The study introduced in this paper confirms that the foundation system of the Taj Mahal in India consists of wells, arches and piers constructed from stone blocks, bricks, watertight mortar and some local materials. Over the 360 year construction period of the Taj Mahal, the site has undergone several changes such as changes in river flow patterns, pollution of river water and new constructions close to the monument; they are pivotal in causing damage to the foundation. Therefore, it is in dire need of conservation, as any damage to it can endanger components of the structure above the foundation. However, there is a dearth of construction information available for comparison between then and now. In this paper, data from available literature were extracted for the analysis of the materials and construction process used at that time. Details of construction materials and techniques are an integral part of structural changes required to conserve the monument in the future.
Application of neural reconstruction of tomographic images in the problem of reliability of flood protection facilities
Authors: Rymarczyk T. , Kłosowski G.
Published: June 2018

The article presents an innovative concept of enhancing the flood embankments and landfills monitoring. The key advantage of
such a solution is to obtain a more detailed distribution of components within a flood barrier. It leads to more early and sufficient
threat detection, considering the exploitation of the building, thus - a vast enhancement of an embankment’s performance. The
method is based on implementing a neural system, composed of a number of parallelly-working neural networks. Each of them
generate a singular point of final output view. By implementing such monitoring measures it is possible to successfully reconstruct
two-and-three dimensional models of flood barriers and dams - including possible breaches and damages within its inner structure. An important advantage of such a solution is the possibility of replacing the systems that monitor hydrotechnical facilities
pixel-by- pixel by neural imaging. The performed research leads to solving the problem of low resolution of such images. As this
problem was of crucial value to tomographic imaging method, it was a main obstacle to the development of neural reconstruction
method. Moreover, as the results may be obtained in real-time and at various levels, these new functionalities stand out in comparison to currently used methods for monitoring protective banks.
The dynamics of wear of cutting inserts during turning of non-homogeneous material on the example of polymer concrete
Authors: Kępczak N. , Rosik R. , Pawłowski W. , Sikora M. , Witkowski B. , Bechciński G. , Stachurski W.
Published: June 2018

The article presents the results of studies on the dynamics of wear of five different cutting inserts (for machining difficult-to-cut materials, for finishing cast iron machining, for roughing cast iron machining, for steel machining and for stainless steel machining)
during turning a non-homogeneous material such as polymer concrete. Polymer concrete is a difficult-to-cut, anisotropic, composite material. During the tests, a record of the components of the cutting force in real time was made. After each machining pass, the
Ra and Rz surface roughness values were measured in the direction perpendicular to the machining marks and photos were taken
under the microscope of the inserts corners, on the basis of which the width of major flank wear land and the width of minor flank
wear land were measured. The view of each insert after the tests was also presented. Finally, the conclusions about the dynamics of
wear of inserts taking part in the study as well as their applicability during polymer concrete turning were formulated.
Identifying the causes of deterioration in the surface finish of a workpiece machined on a rail wheel lathe
Authors: Lehrich K. , Wąsik M. , Kosmol J.
Published: June 2018

Operational problems often remain undetected until a machine is commissioned and first machining is attempted. Heavy-duty machines are a specific group of machine tools due to the character of their manufacturing process. As they are often manufactured
as single units, which involves high production costs, there are no prototype versions built and no tests are performed on them.
Therefore, before the machine is complete, computer simulation methods are often the only validation tools of a machine project
at the stage of designing. The variety of applications and the individuality of production are the reasons for the lack of standards
defining the rigidity and precision of the cutting process performed by heavy machine tools. In this case analysis, the authors are
considering a heavy duty rail wheel lathe, in which some issues were found during its exploitation which make it impossible to
achieve the required shape, dimensions and surface finish, while working at set parameters. This article presents a comprehensive
approach to the identification of the form and frequency of a machine tool supporting structure’s self-vibrations and their potential
sources in the case study of a horizontal lathe for railway wheelsets. The authors, drawing on the results of their long-standing
research and their experience in the field of heavy machine tool design and testing, indicate self-excited vibrations as a key factor
machine’s operational behaviour, which is rarely considered in this type of machines
Fem analysis of pressure vessel with an investigation of crack growth on cylindrical surface
Authors: Balac M. , Grbovic A. , Petrovic A. , Popovic V.
Published: June 2018

To ensure reliability of pressure vessels during service it is necessary to (1) know properties of materials used in their design
and (2) evaluate vessels’ behaviour under different working conditions with satisfying accuracy. Due to various technical and/
or technological requirements, nozzles are usually welded on vessel’s shell producing geometrical discontinuities that reduce
the safety factor. To evaluate their influence, vessels with two different nozzles were experimentally studied and critical areas
for crack initiation have been identified by 3D Digital Image Correlation (DIC) method. After that, the numerical analysis of
equivalent 3D finite element model was performed and obtained results were compared with experimental values. In the most
critical area, next to the one of the nozzles, crack was initiated and then growth of the damage was simulated using extended
finite element method (XFEM). In this paper evaluation of stress intensity factors (SIFs) along crack path is presented, as well
as the most probable direction of the crack propagation on the shell. Based on SIFs values, critical length of the crack and
number of pressure cycles to the final failure were estimated.
Preliminary modeling of overspray particles sedimentation at heat recovery unit in spray booth
Authors: Nikończuk P.
Published: June 2018

Overspray sediments settling on the recuperator’s fins cause operational problems. The cross sections of the recuperator’s channels gradually decrease and finally it result in clogging of the recuperator. The layers of sediments cause air flow resistance and
also heat transfer resistance. The paper presents preliminary results of sedimentation process modeling. The model of overspray
creation takes into account a droplets size and particles concentration in air stream inside extraction ducting. Simulation results
are compared with measurements conducted in three commercial spray booths.
The Persuasive Roles of Digital Games: The Case of Cancer Games
Authors: De la Hera Conde-Pumpido Teresa
Published: June 2018

Using behavioral scientist B. J. Fogg’s conceptual framework on the role computer technology plays for users as a starting point, this article argues that persuasion through digital games can be approached from three different perspectives: digital games as media for persuasion, digital games as tools for persuasion and digital games as social actors for persuasion. In this article, I use five cancer gaming cases to illustrate how these three different persuasive roles can be used to accomplish different persuasive goals. In this respect, I explain how each of these persuasive roles digital games can play in the process of persuasion can serve to support cancer patients to face three different challenges: (1) lack of information about the treatment or the disease itself, (2) lack of motivation to start or continue with the treatment, and (3) difficulties in coping with the treatment or the disease. The analysis of these games is theoretical in nature and is done to illustrate my arguments. The categorization proposed in this article can be used as an analytical approach for the study of persuasive gaming strategies.
Do We Need Permission to Play in Public? The Design of Participation for Social Play Video Games at Play Parties and ‘Alternative’ Games Festivals
Authors: Love Lynn H. C.
Published: June 2018

Play is fundamental to being Human. It helps to make sense of the self, to learn, to be creative and to relax. The advent of video games challenged traditional notions of play, introducing a single player experience to what had primarily been a communal social activity. As technology has developed, communal play has found both online and real-world spaces within video games. Online streaming, multiplayer games and built-in spectator modes within games underpin online communal play experiences, whilst ‘alternative’ games festivals, play parties and electronic sports, provide real world spaces for people to meet, play and exchange knowledge relating to both playing and making video games. This article reports the study of social play events which bring people together in the same space to explore video games making and playing. Expert interviews with curators, and event facilitators provides qualitative data from which design processes are formalised into a ‘model of participation’ of social play. Four key areas of balance are proposed as core considerations in supporting participation in event design. The study of these events also suggests that their design and fostering of participation has the potential to evoke cultural change in game making and playing practices.

Published: June 2018

A limpeza do sistema de canais radiculares é realizada com instrumentos de aço inoxidável e mais recentemente com instrumentos de níquel-titânio (NiTi), estes possuem maior flexibilidade e resistência. Porém, durante este processo pode ocorrer a separação dos instrumentos no interior dos canais radiculares. O presente trabalho objetivou avaliar por meio das anotações e radiografias periapicais dos prontuários quais elementos dentários, raízes e terços radiculares são mais susceptíveis para ocorrência de fratura de instrumentos rotatórios ou reciprocantes de NiTi. Para tanto, procedeu-se análise de dados recolhidos junto a 500 prontuários em atendimento odontológico no curso de especialização em Endodontia da IMED cujas radiografias foram avaliadas e quando visualizado um fragmento de instrumento este era identificado e registrado em planilha específica. Sobre o total de 500 prontuários atendidos 5,2% dos molares tratados apresentaram fratura de instrumento de NiTi, destes, 1,2% pertence a molares superiores e 4,0% a molares inferiores. Em relação ao canal radicular mais envolvido com a fratura do instrumento, nos molares superiores foi o mésio-vestibular (MV) com 83,33% e nos molares inferiores o mésio-lingual (ML) em 70% dos casos, em ambos os casos o terço apical foi o mais envolvido: 66,67% nos superiores e 80% nos inferiores. Desta forma os molares inferiores representaram o grupo dentário mais envolvido com fratura de instrumentos onde no seu canal mésio-lingual foi registrado a maior incidência de fraturas e o terço apical representou a totalidade da posição da fratura dentro do canal radicular.
Didactic Modeling in Teaching Students Pedagogues
Authors: Neminska Rumyana
Published: June 2018

This article is a theoretical study on a model of higher education education at Thracian University, Faculty of Pedagogy in Bulgaria. The teaching process in the subject "Primary School Pedagogy" is being subjected to didactic study in student pedagogues. Theoretically, the methods by which the teachers interact with the students are studied. In their understanding, the interactive lecture in the academic environment is much more successful. The article follows the steps of modeling a didactic matrix in its entirety. There is a need for special didactic modeling from the position of the different topics and from the position of the learning activities with understanding and experience. He argues that didactic modeling evolves into a specially organized simulation-based learning environment. Thus, once, it modeled the learning environment and the second time: a simulation environment was modeled specifically for it. The unique in this process of learning is that it is led by two professors - associate professor and professor. The planned training takes the form of dialogue in front of the students they are involved in. In developing academic lectures, teachers define educational goals, construct training materials, and evaluate how the didactic model is constructed. The didactic model is flexible and adaptable. It gives every student the opportunity to present his strong side so he is successful. The student develops his/her less good skills so that a training pedagogical balance is achieved at the end of the training.

Authors: Obregón Manuel de Jesús
Published: June 2018

La reforma tributaria contenida en la Ley 1819 del 29 de diciembre de 2016 trajo importantes modificaciones a los aportes voluntarios a los fondos privados de pensiones, a las compañías de seguros. Como novedad, se permiten aportes voluntarios a los fondos obligatorios de pensiones, con el beneficio de no constituir renta ni ganancia ocasional para el trabajador o partícipe independiente. Un beneficio muy importante al momento de calcular el impuesto de renta por el sistema cedular, al poderse deducir en su totalidad el aporte. Igualmente, se extienden los beneficios de las cuentas de Ahorro para el Fomento de la Construcción, AFC, a las cuentas de ahorro del Fondo Nacional del Ahorro, AVC, y de las entidades de la Economía Solidaria, vigiladas por la Superintendencia Financiera o Superintendencia de Economía Solidaria. Además, existen importantes cambios en las retenciones contingentes cuando los aportes sean retirados sin cumplir los requisitos establecidos en la ley. Por ello, los aportes voluntarios y obligatorios deben cumplir ciertos requisitos de permanencia mínima y destinación específica para obtener el beneficio tributario. Por lo anterior, el objetivo del presente trabajo consiste en distinguir y analizar los distintos beneficios tributarios de los aportes voluntarios y de las cuentas de ahorros para el fomento de la construcción, AFC y AVC, clasificándolos para su estudio de acuerdo con sus rasgos distintivos. Igualmente, se analiza la incidencia de dichos beneficios fiscales en la depuración de la renta de las personas naturales en el sistema cedular, presentando al final del ensayo un cuadro que resume el tema analizado.

ATUAÇÃO MUNICIPAL NA MITIGAÇÃO DE IMPACTOS AMBIENTAIS
Authors: Sousa Ricardo Azevedo Mamédio de , Rocha Renata Rodrigues de Castro
Published: June 2018

O presente trabalho buscou verificar a regulação da exigência de compensação ambiental para empreendimentos que, embora não se equiparem aos exemplificados no art. 2º da Resolução Conama nº 001, de 23 de janeiro de 1986, produzem impactos com consequências sensíveis à qualidade do meio ambiente natural, situando-se em posição intermediária na escala de atividades potencialmente prejudiciais às condições ecológicas da sua área de influência. Para tanto, através de pesquisa bibliográfica e análise da legislação e doutrina pertinentes ao objeto de pesquisa, analisou-se o conceito e a natureza jurídica do instituto da compensação ambiental, bem como a posição ocupada pelos municípios na distribuição de competências material e legislativa nessa seara. Concluiu-se pela viabilidade da instituição de compensação ambiental municipal por impactos de média magnitude, assim como pela possibilidade de se destinar os recursos arrecadados para a restauração das funções ecológicas essenciais à conservação da natureza e à sadia qualidade de vida da população, e não exclusivamente para a criação e manutenção de unidades de conservação.
SEGURANÇA ALIMENTAR E AGROTÓXICOS: A situação do glifosato perante o princípio da precaução
Authors: Gusmão Leonardo Cordeiro de , Ribeiro José Cláudio Junqueira , Custódio Maraluce Maria
Published: June 2018

O presente trabalho utiliza do método jurídico de raciocínio dedutivo, com aplicação da técnica de pesquisa bibliográfica e documental. Nele, pretende-se verificar se o Poder Público está sendo omisso no que tange à aplicação do Princípio da Precaução, sob a perspectiva da segurança alimentar, em relação à substância glifosato, que é o agrotóxico mais utilizado no Brasil, em especial nas monoculturas com cultivo de soja geneticamente modificada. A partir de resultados de estudos publicados pela Organização Mundial de Saúde, no qual foi qualificado como cancerígeno e causador de danos ao DNA e a cromossomos de células humanas, em conjunto com a deficiência de informações constantes no Programa de Análise de Resíduo de Agrotóxicos em Alimentos, publicado pela ANVISA, infere-se que pela existência de dúvida científica razoável se justificaria a aplicação de medidas de precaução, inclusive a proibição da utilização do glifosato na produção de alimentos no país, efetivando o direito à segurança do consumidor.

La (quasi)disparition des gynolectes et pédolectes et le développement des incivilités (insultes et propos violents) n’empêchent pas l’apparition de nouveaux domaines tabous en français. Les fondamentalistes religieux s’insurgent encore contre ce qu’ils considèrent être des blasphèmes mais il sont minoritaires. En revanche les propos machistes, racistes, antisémites, négationnistes provoquent des réactions indignées de la part de la population, beaucoup plus sensible à ces sujets, et font l’objet de poursuites devant les tribunaux et de condamnations.
