Authors: Carvalho Eliza Cristiane de , Bisson Amanda Albino , Hespanhol Lucas Alvarenga , Pereira Nicoli Maria , Fregoneze Andrea Paula , Brancher João Armando , Torres Maria Fernanda Pioli
Published: August 2019

Introduction: Sotos Syndrome is a dominant autossomic disease caused by a mutation in NSD1 gene localized in chromosome 5. The craniofacial phenotype of Sotos Syndrome is quite distinctive, especially in the young child, and includes macrocephaly, widelyspaced eyes, prominent chin and mandible, high and curved forehead, palpebral slits oblique and downward, long and narrowface. This phenotype plays an important role in the identification of this syndrome. Objective: The aim of this study was to analyze the craniofacial anthropometric landmarks of a young adult male with medical diagnosis of Sotos Syndrome. Material and methods: Using noninvasive method of craniofacial anthropometry, twenty five anthropometric measurements were taken of the individual and compared with the facial pattern of non-syndromic individuals,matched in gender and age. The findings were standards and converted to Z-scores. Results: the data analysis showed that the majority of variables were in supernormal range (greater than +2 standard deviation (SD). None none of them was in the subnormal range (less than –2SD). Conclusion: Anthropometric analysis of Sotos Syndrome demonstrated the usefulness of craniofacial analysisin defining abnormal craniofacial dimensions.
Neutrophils as Sentinel Cells of the Immune System: A Role of the MPO-halide-system in Innate and Adaptive Immunity
Authors: Marcinkiewicz Janusz , Walczewska Maria
Published: August 2019

:

For decades, neutrophils were generally regarded as the cells of innate immunity with proinflammatory and phagocytic properties involved in a dual activity, beneficial (antimicrobial) and detrimental (tissue damage). Importantly, until the discovery of toll-like receptors (TLRs), a role of neutrophils in adaptive immunity was limited to the effector stage of humoral response and phagocytosis of opsonized antigens. Moreover, in common opinion, neutrophils, as well as the entire innate immune system, were not functionally associated with adaptive immunity. At the time we demonstrated protein chlorination by HOCl, the major product of neutrophil MPO-halide system enhances protein immunogenicity. Based on this discovery, we proposed, as the first, a new role for neutrophils as APC-accessory cells involved in the induction stage of adaptive immunity. Thereafter, we developed our theory concerning the role of neutrophils as the cells which link innate and adaptive immunity. We proposed that protein modification by HOCl may act as a neutrophildependent molecular tagging system, by which sentinel dendritic cells can faster recognise pathogen- derived antigens. Contemporaneously, it was demonstrated that taurine, the most abundant free amino acid in neutrophil cytosol and the major scavenger of HOCl, is a part of the oxidantantioxidant network and is responsible for the regulation and termination of acute inflammation. Moreover, it has been described, that taurine chloramine (TauCl), the physiological products of the reaction of HOCl with taurine, show anti-microbial and anti-inflammatory properties.

:

In this review, the role of HOCl, taurine and TauCl in innate and adaptive immunity will be discussed.
The Impact of Working Memory Training on Cognitive Abilities in Older Adults: The Role of Cognitive Reserve
Authors: Mičič Sara , Horvat Marina , Bakracevic Karin
Published: August 2019

Objectives:

The aims of this study were to determine whether Working Memory (WM)
training improves the cognitive functioning of older adults and to determine the role of cognitive
reserve in WM training.

Method:

Twenty-one older adults, aged between 65 and 91 years were included in the study. Ten
of them were in the experimental group and 11 in the passive control group. The experimental
group underwent 15 training sessions of n-back training over a period of five weeks, whereas the
control group remained passive. All participants (from the experimental and control group) were
tested before the training, one week after the training, and three months after the training with Rey–
Osterrieth/Taylor Complex Figure test (ROCF), Digit span, and TMT (part A and part B).

Results and Conclusion:

Results of our study suggest that although the experimental group slightly
improved their performance on the trained task, the progress was not statistically significant. There
was also no statistically significant transfer of training effects onto tasks of visual-spatial and verbal
memory, as well as those related to executive functioning. However, the study did identify a statistically
significant correlation between cognitive reserve and certain tests performed at the final testing:
tasks measuring executive functioning and spatial ability. Results also revealed that the group
that showed improvement in the training task was significantly better in the ROCF test in comparison
with the group that had not improved their performance on the N-back task. Thus, visual-spatial
abilities (visual perception, construction, and memory) were more connected with success in WM
training, than other measured cognitive abilities (e.g. verbal and numerical memory).

Authors: Soliman Fathi S. , El-Maghrabi Heba H. , Zaki Tamer , Nada Amr A. , Zahran Fouad
Published: August 2019

Objective::

Six ultra pure Paraffin Waxes (PW) were successfully fractionated at 35°,
30°, 25°, 20°, 15° and 10°C. The bimetallic oxide (Ferberite) was successfully synthesized by Microwave
assisted method.

Methods:

Enhanced Phase Change Materials (PCMs) were designed by loading W/Fe bimetallic
oxides in the ultra pure PW matrix at 1, 2, 3, 4 and 5 wt. %. paraffin wax, W/Fe bimetallic oxide
and the resultant composite blends were characterized by X-ray Diffraction (XRD), Gas Chromatography
(GC), Deferential Scanning Calorimetry (DSC), Polarized Optical Microscope (POM),
Scanning Electron Microscopy (SEM) and High Resolution Transmission Electron Microscopy
(HRTEM). In addition to testing the thermal conductivity of the designed blends. According to
SEM, DSC and POM data, the prepared nanocomposite was homogeneously dispersed into the
selected PW matrix.

Results:

Data revealed that thermal conductivity of the designed composite increases with increasing
the loading ratio of W-Fe bimetallic oxides. The total latent heat storage ΔHT of the initial
sample was improved from 295.91 J/g to 311.48 J/g at 5 wt. % loading percent.

Conclusion::

Thermal conductivity was improved from 8.54 to 21.77 W/m2k with increasing up to
255% in comparison with pure paraffin wax.

Traditional and folklore medicines have gained popularity throughout the world
due to their safety. Herbal medicines with pharmacological activities and nutritional value are
the most popular choice. Cultural and geographical factors of Bangladesh make it a vast
source for herbal medicines. In addition, the cost-effectiveness of herbal medicines has also
played an important role to make it a drug of choice among the developing countries like
Bangladesh. People of Bangladesh have been using plants for centuries to treat different
wounds caused by excision and incision. In this current review, we have gone through an extensive
literature search to find out the four most commonly used medicinal plants for the
treatment of wounds and their pharmacological activities in scientific researches. The featured
plants of this review articles are, Calotropis gigantea, Cynodon dactylon, Acorus calamus and
Justicia gendarussa. In traditional and herbal medicines, many plants are used without their
scientific validation and we intend to perform a literature review in order to find out the potential
scientific value of the featured plants. In addition, with pharmacological activities, their
traditional formulation as a wound healing drug is also added to this article. This study will
help validate the uses of these plants as traditional medicine and for researchers to find out potential
therapeutic drugs according to their pharmacological studies.

AbstractThe results of investigation of thermoelectric materials fabricated by spark plasma sintering and based on Si_1 –_ x Ge_ x solid solutions doped with Sb to a concentration of 0–5 at % are presented. It was found that, at Sb concentration below 1 at %, efficient doping of the solid solution was carried out during the sintering process, which allowed us to form a thermoelectric material with a relatively high thermoelectric figure of merit. An increase in the concentration of antimony in the range of 1–5 at % led to a change in the mechanism of doping, which resulted in an increase in the resistance of materials and the segregation of Sb into large clusters. For such materials, a significant decrease in the Seebeck coefficient and thermoelectric figure of merit was noted. The highest obtained thermoelectric figure of merit (ZT) with Sb doping was 0.32 at 350°C, which is comparable with known analogues for the Ge_ x Si_1 –_ x solid solution.

AbstractThe spectrum of amplification of terahertz radiation in a structured active graphene bilayer consisting of two identical periodic graphene microribbon arrays separated by a thin dielectric barrier layer is theoretically investigated. The system supports optical and acoustic plasmon modes. The resonant frequencies of the optical and acoustic modes change oppositely with the dielectric-layer thickness, which allows plasmon-mode anticrossing. It is shown that the investigated graphene structure is characterized by a strong plasmon response and giant terahertz-radiation amplification at plasma resonance frequencies in the vicinity of the anticrossing between the optical and acoustic plasmon modes at room temperature.

AbstractThe results of experiments aimed at the observation of split 1 s states in Mg-doped Si are reported. From the results, it is possible to determine the chemical shift and exchange interaction energy of a neutral Mg donor in Si. The position of the 1 s ( E ), 1 s ( T _2), and 2 s ( A _1) parastates determines the possibility for attaining population inversion and the specific mechanism of stimulated Raman scattering. The energy of the 1 s ( T _2) parastate is determined from the position of the Fano resonances in the photoconductivity spectrum of Si:Mg at T = 4 K, and the energies of the 1 s ( T _2) and 1 s ( E ) orthostates from the transmittance spectra at elevated temperatures. On the basis of the experimental data, the relaxation rates are estimated, and the possible mechanisms of stimulated emission are analyzed.

A comparative analysis of Hall effect in substitutional solid solutions Ho0.5Lu0.5B12, Mn1-xFexSi (0≤ x≤1) and Eu1-xGdxB6 (x<0.04) is carried out at temperatures 2-300 K in magnetic fields up to 8 T. Anomalous Hall effect rhoxyA~rhoxxM is identified for the systems with different kinds of magnetic frustration. Linear scaling rhoxyA~rhoxx, which is detected at resistivity rhoxx~0.01-1 mOmega·cm out from the region of applicability of classical skew-scattering model, is associated with the increase of spin fluctuations amplitude in paramagnetic phases of the investigated compounds with noncollinear magnetic structure. Topological contribution to Hall effect is extracted for Ho0.5Lu0.5B12 and Eu1-xGdxB6, its amplitude varying from 80 nOmega·cm (for Ho0.5Lu0.5B12) up to 7.5 μOmega·cm (for Eu0.97Gd0.03B6).
Тепловые эффекты при кристаллизации сплавов с неограниченной и ограниченной растворимостью компонентов

Published: August 2019

The processes of crystallization of two-component alloys with unrestricted and limited solubility of the constituent components were investigated by the method of differential high-resolution scanning calorimetry. It was found that in all cases a jump in the heat evolution of crystallization that is noticeable in magnitude and speed is recorded directly below the liquidus line. Traditional approaches in describing the development of crystallization processes in the intercritical temperature range do not provide an explanation for the observed phenomena.
It is assumed that the observed effects are associated with the formation of a large number of local microvolumes (concentration fluctuations) enriched in the leading crystallization component. Their appearance precedes the beginning of processes of spontaneous formation of a large number of crystals in a noticeable volume of the liquid phase.

AbstractAn atomic structure of crystals of the complex [Eu_2(Quin)_42Н_2O2Dipy]_2 · 2(NO_3) · Н_2O, (Quin, anion of quinaldic acid; Dipy, 2,2'-dipyridyl), which exhibited intense luminescence and triboluminescence, has been investigated via the X-ray diffraction analysis. The structure of crystals of the compound appeared to be of an islelike type and were represented by two separate crystallographically independent complex dimers, outer-sphere [NO_3]^−1-groups, and water molecules. Structural aspects of the formation of the luminescent and triboluminescent properties of the compound have been discussed. The role of cleavage planes at crystal destruction has been established.

The effect of the numerical aperture of a light beam probing an object on the value measured by a confocal interference microscope when determining the thickness of a layered object for the case of a significant effect on the signal of the spherical aberration arising in the probe beam at its propagation through an object has been theoretically and experimentally investigated. Taking into account the influence of spherical aberration on the signal the dependence of the measured value on the numerical aperture has been obtained. The criterion of the “aberration-free” propagation of the beam probing an object has been established and the condition under which the effect of spherical aberration on the signal of a confocal microscope can be neglected has been determined. An approximate analytical expression which allows to determine the “aberration-free” width of angular spectrum of the probing light beam taking into account the empirical correction factor has been obtained. The limits of applicability of the analytical dependence of the measured value on the numerical aperture, which was obtained earlier for the case of negligible influence of spherical aberration on the signal of a confocal microscope, have been determined.
Antismoking Advertisements and Price Promotions and Their Association With the Urge to Smoke and Purchases in a Virtual Convenience Store: Randomized Experiment
Authors: Dutra Lauren McCarl , Nonnemaker James , Bradfield Brian , Taylor Nathaniel , Guillory Jamie , Feld Ashley , Kim Annice
Published: August 2019

Background

Point of sale (POS) advertising is associated with smoking initiation, current smoking, and relapse among former smokers. Price promotion bans and antismoking advertisements (ads) are 2 possible interventions for combating POS advertising.

Objective

The purpose of this analysis was to determine the influence of antismoking ads and promotions on urges to smoke and tobacco purchases.

Methods

This analysis examined exposure to graphic (graphic images depicting physical consequences of tobacco use) and supportive (pictures of and supportive messages from former smokers) antismoking ads and promotions in a virtual convenience store as predictors of urge to smoke and buying tobacco products among 1200 current cigarette smokers and 800 recent quitters recruited via a Web-based panel (analytical n=1970). We constructed linear regression models for urge to smoke and logistic regression models for the odds of purchasing tobacco products, stratified by smoking status.

Results

The only significant finding was a significant negative relationship between exposure to supportive antismoking ads and urge to smoke among current smokers (beta coefficient=−5.04, 95% CI −9.85 to −0.22; P=.04). There was no significant relationship between graphic antismoking ads and urge to smoke among current smokers (coefficient=−3.77, 95% CI −8.56 to 1.02; P=.12). Neither relationship was significant for recent quitters (graphic: coefficient=−3.42, 95% CI −8.65 to 1.81; P=.15 or supportive: coefficient=−3.82, 95% CI −8.99 to 1.36; P=.20). There were no significant differences in urge to smoke by exposure to promotions for current smokers (coefficient=−1.06, 95% CI −4.53 to 2.41; P=.55) or recent quitters (coefficient=1.76, 95% CI −2.07 to 5.59; P=.37). There were also no differences in tobacco purchases by exposure to graphic (current smokers: coefficient=0.93, 95% CI 0.67 to 1.29; P=.66 and recent quitters: coefficient=0.73, 95% CI 0.44 to 1.19; P=.20) or supportive (current smokers: coefficient=1.05, 95% CI 0.75 to 1.46; P=.78 and recent quitters: coefficient=0.73, 95% CI 0.45 to 1.18; P=.20) antismoking ads or price promotions (current smokers: coefficient=1.09, 95% CI 0.86 to 1.38; P=.49 and recent quitters: coefficient=0.90, 95% CI 0.62 to 1.31; P=.60).

Conclusions

The results of this analysis support future research on the ability of supportive antismoking ads to reduce urges to smoke among current cigarette smokers. Research on urges to smoke has important tobacco control implications, given the relationship between urge to smoke and smoking cigarettes, time to next smoke, and amount smoked.

UNSTRUCTURED

There has been a growth in the number of web-based trials of web-based interventions, adding to an increasing evidence base for their feasibility and effectiveness. However, there are challenges associated with such trials, which researchers must address. This discussion paper follows the structure of the Down Your Drink trial methodology paper, providing an update from the literature for each key trial parameter (recruitment, registration eligibility checks, consent and participant withdrawal, randomization, engagement with a web-based intervention, retention, data quality and analysis, spamming, cybersquatting, patient and public involvement, and risk management and adverse events), along with our own recommendations based on designing the Relatives Education and Coping Toolkit randomized controlled trial for relatives of people with psychosis or bipolar disorder. The key recommendations outlined here are relevant for future web-based and hybrid trials and studies using iterative development and test models such as the Accelerated Creation-to-Sustainment model, both within general health research and specifically within mental health research for relatives. Researchers should continue to share lessons learned from conducting web-based trials of web-based interventions to benefit future studies.

BACKGROUND

In the current wave of educational reforms, understanding teaching styles of medical faculty will help modify instructional strategies for effective teaching. Few studies have probed unique teaching styles of medical academics.

OBJECTIVE

This study compared the preferred teaching styles of faculty from seven medical schools.

METHODS

The validated Grasha-Riechmann teaching style inventory was administered online to the entire medical faculty actively involved in teaching in 7 medical schools in the United Arab Emirates, Saudi Arabia, Malaysia, Pakistan, Sudan, and the Netherlands.

RESULTS

We received 248 responses from 460 invitees (response rate; 54%). Overall, there was an agreement with the majority of suggested teaching styles. However, we also observed significant variations across seniority, gender, and institutions. The most common teaching style, stimulating students’ inquisitive behaviors to satisfy their curiosity, was preferred by 195 (68%) teachers. As many as 117 (47%) academics disagreed with the teaching philosophy of delivering course contents by strictly following learning outcomes. Interestingly, the teaching styles of young teachers with less than 10 years of experience (112/248) more closely matched with students’ learning styles. Female teachers (114/248) were more willingly to solicit their students for understanding course contents, while male teachers tended to allow more autonomy by allowing students to set their learning agenda.

CONCLUSIONS

This study showed a student-centered approach and motivating students for the discovery of their scientific curiosity as the most preferred teaching styles. These findings can help educators in modifying medical curricula and in developing faculty enhancement programs to enrich the learning climate.
A Questionnaire for Assessing User Satisfaction With Mobile Health Apps: Development Using Rasch Measurement Theory (Preprint)
Authors: Melin Jeanette , Bonn Stephanie Erika , Pendrill Leslie , Trolle Lagerros Ylva
Published: August 2019

BACKGROUND

Mobile health (mHealth) apps offer great opportunities to deliver large-scale, cost-efficient digital solutions for implementing lifestyle changes. Furthermore, many mHealth apps act as medical devices. Yet, there is little research on how to assess user satisfaction with an mHealth solution.

OBJECTIVE

This study presents the development of the mHealth Satisfaction Questionnaire and evaluates its measurement properties.

METHODS

Respondents who took part in the Health Integrator Study and were randomized to use the Health Integrator smartphone app for lifestyle changes (n=112), with and without additional telephone coaching, rated their satisfaction with the app using the new 14-item mHealth Satisfaction Questionnaire. The ratings were given on a 5-point Likert scale and measurement properties were evaluated using Rasch measurement theory (RMT).

RESULTS

Optimal scoring was reached when response options 2, 3, and 4 were collapsed, giving three response categories. After omitting two items that did not fit into the scale, fit residuals were within, or close to, the recommended range of ±2.5. There was no differential item functioning between intervention group, age group, or sex. The Person Separation Index was 0.79, indicating that the scale’s ability to discriminate correctly between person leniency was acceptable for group comparisons but not for individual evaluations. The scale did not meet the criterion of unidimensionality; 16.1% (18/112) of the respondents were outside the desired range of −1.96 to 1.96. In addition, several items showed local dependency and three underlying dimensions emerged: negative experiences, positive experiences, and lifestyle consequences of using the mHealth solution.

CONCLUSIONS

In times where mHealth apps and digital solutions are given more attention, the mHealth Satisfaction Questionnaire provides a new possibility to measure user satisfaction to ensure usability and improve development of new apps. Our study is one of only a few cases where RMT has been used to evaluate the usability of such an instrument. There is, though, a need for further development of the mHealth Satisfaction Questionnaire, including the addition of more items and consideration of further response options. The mHealth Satisfaction Questionnaire should also be evaluated in a larger sample and with other mHealth apps and in other contexts.

A B S T R A C TDissolution of gold from roasting concentrate of gold ore using potassium thiocyanate with the presence of ferric chloride as an oxidizer was investigated. The concentrate was taken from Lengkukai gold mine. Gold ore particles under 53 µm in size were roasted at varied temperature, separated using wet magnetic separator, and finally leached. The X-ray diffraction (XRD) analysis showed that there were phase changes after roasting with the emergence of new phases such as hematite, pyrrhotite, and almandine. Leaching of gold concentrate after roasting and magnetic separation showed that gold was in non-magnetic concentrate at 950oC with the highest gold dissolution of 0.95 mg/L, while magnet concentrate was completely absent. Experiments with the addition of Fe3+ ion oxidizers for 24-hour range did not have significant effect on gold dissolution. The highest gold concentration obtained of 2.29 mg/L was obtained at 12 hours with 0.1 M FeCl3. The increase of thiocyanate reagent concentrations, which showed a linear correlation to gold dissolution, produced up to 2.25 mg/L of gold concentration (12 hours at 0.3 M KSCN).Keywords: ferric ion gold dissolution; gold concentrate; roasting; thiocyanate A B S T R A KPelarutan emas dari konsentrat hasil roasting bijih emas tambang Lengkukai menggunakan reagen pelindi kalium tiosianat dengan penambahan ferric chloride sebagai oksidator telah diteliti. Partikel bijih emas dengan ukuran di bawah 53 µm di-roasting pada berbagai temperatur kemudian dipisahkan menggunakan pemisah magnetik basah dan akhirnya dilindi. Hasil analisis X-ray diffraction (XRD) menunjukkan adanya perubahan fase setelah roasting dengan munculnya fase-fase baru yaitu hematit, pirohitit dan almandin. Pelindian konsentrat emas hasil roasting dan pemisahan magnetik menunjukan emas berada pada konsentrat non magnet temperatur roasting 950 oC dengan pelarutan emas paling tinggi sebesar 0,95 mg/L, berbeda dengan konsentrat magnet yang sama sekali tidak ada. Percobaan dengan penambahan oksidator ion Fe3+ selama rentang 24 jam tidak memberikan efek yang signifikan terhadap pelarutan emas. Dari penelitian ini didapatkan konsentrasi emas tertinggi sebesar 2,29 mg/L pada 12 jam dengan konsentrasi FeCl3 0,1 M.

What Russian universities have chances to enter in 2020 TOP-100 of three leading world rankings?
Authors: Moskovkin V. M. , Zhang He , Sadovski M. V.
Published: August 2019

The analysis of the positioning of 52 leading Russian universities in three world rankings (QS, THE, ARWU) was carried out over a seven-year time interval. It is shown that from the analysis of materials and the roughest predictions based on linear extrapolation of data, it can be concluded that none of the 52 leading Russian universities can enter the TOP-100 of the considered ratings. It was concluded that at the very beginning of the launch of the 5–100 project an unreasonable assumption was made that five leading Russian universities could be included in the TOP-100 of one or several of the three world rankings. It is shown that for successful implementation of the project it would be necessary to carry out imitating modeling previously.
Direito Penal e Estado Democrático de Direito: a aplicação da lei penal a serviço da democracia
Authors: Guimarães Cláudio Alberto Gabriel , Mariz Ester Avelar dos Santos Rios
Published: August 2019

Partindo-se do entendimento de que a aplicação das leis punitivas estatais deve ser extremamente comprometida com os ideais democráticos expostos na Constituição Federal, a presente pesquisa tem como objetivo principal fomentar as discussões referentes à realidade prática desse compromisso, analisando, de forma crítica, a discrepância existente entre teoria e prática no que tange à efetividade dos mecanismos de controle social na manutenção dos ideais democráticos em um ambiente sustentado pela dominação de classes. Ademais, o trabalho produzido tem como escopo compreender o real significado de democracia e Estado Democrático de Direito no contexto político, econômico e social do Estado brasileiro contemporâneo, bem como propor idéias para superar a enorme e persistente crise do sistema penal pátrio, uma vez que a realidade se encontra bem distante do ideal a ser perseguido.
Neoconstitucionalismo, discricionariedade e decisão judicial: um diálogo entre Robert Alexy e Lênio Luiz Streck
Authors: Pereira Ana Lucia Pretto , Cordeiro Bruna De Oliveira
Published: August 2019

Resumo: O presente artigo visa discutir questões relacionadas à interpretação do direito sob o movimento teórico chamado neoconstitucionalismo, a partir de contribuições teóricas de Robert Alexy e Lenio Luiz Streck. A abordagem iniciará, dentre outros aspectos, por considerações sobre o neoconstitucionalismo, seguida pela interpretação do direito com o uso de regras e princípios de acordo com Robert Alexy, concluindo com a proposta de Lênio Luiz Streck, segundo a qual uma decisão judicial será legítima se fundada em uma interpretação sistemática do direito adequada aos princípios informadores de uma determinada comunidade política. Uma vez que a proposta de Robert Alexy acerca da interpretação judicial sobre direitos fundamentais atribui uma considerável margem de discricionariedade ao julgador, ela se aproxima do que Streck chama de escolha judicial, em lugar de decisão judicial, o que seria criticável, segundo Streck.
O controle jurisdicional dos atos políticos: uma força entre a tirania e a judiciocracia
Authors: Priess Alexandre Dos Santos , Da Silva José Everton , De Melo Guilherme Thomé
Published: August 2019

O Estado deve operar, mediante seus três Poderes, de maneira harmônica e, para este fim, há a atividade de controle estatal, exercida por cada um deles reciprocamente. No entanto, existem hipóteses de controle controversas, tais como a circunstância de o Poder Judiciário fiscalizar os atos políticos emanados pelo Governo. A presente pesquisa visou discutir a viabilidade do exercício do controle jurisdicional de atos políticos com a finalidade de proteger e aplicar os direitos fundamentais que possam ser por eles ameaçados ou violados, a partir da interpretação concretista da Constituição. Para tanto, utilizou-se o método indutivo para abordar tópicos referentes às funções política e jurisdicional do Estado e ao dever que este tem de concretizar os direitos fundamentais. O trabalho resultou na constatação da possibilidade do controle jurisdicional dos atos políticos quando prejudiciais aos direitos fundamentais.
Parcerias público-privadas: amplitude da capacidade institucional em prestação de serviços públicos
Authors: Pereira Maria Marconiete Fernandes
Published: August 2019

RESUMOO trabalho mostra a inter-relação do uso da expressão “parcerias” no contexto de concessões administrativas e patrocinadas, significando a colaboração estabelecida entre o setor público e o privado. O instituto jurídico das concessões renova-se com a criação do sistema de Parceria Público-Privada. Tem como objetivo a execução de obras, a elaboração de projetos, financiamentos, gestão, operações e manutenção de serviços públicos. Busca-se com ele melhorar a prestação dos serviços em termos de eficiência e de resultados. Essa espécie de parceira é analisada neste artigo com base nas modalidades de concessões patrocinadas e administrativas, sua aplicabilidade em consonância com as diretrizes institucionais, bem como a importância do procedimento licitatório. O modelo teórico proposto sugere que a adoção das parcerias público-privadas poderá ser uma das vias institucionais para a melhoria da capacidade na prestação de serviços públicos.ABSTRACTThis paper shows the term "partnerships" use on administrative and sponsored concessions meaning the collaboration established between public and private sectors. The legal concessions are renewed with Public-Private Partnership rules. The objective of this paper is to analyze execution of works, elaboration of projects, financing, management, operations and maintenance of public services. It is intended find ways to improve the service success in terms of efficiency and better results. Partnership is analyzed based on modalities of sponsored and administrative concessions, their applicability according to institutional guidelines and the importance of bidding procedure. The theoretical model proposed suggests that the adoption of Public-Private Partnerships could be one institutional way to improve the capacity to provide public services.
Criminalização do aborto no Brasil como violação à Convenção Interamericana de Direitos Humanos: possibilidades jurisprudenciais
Authors: Klock Gabriel Klemz , Lixa Ivone Fernandes Morcilo
Published: August 2019

O presente artigo pretende verificar a possibilidade de a criminalização do aborto no Brasil, através dos artigos 124 e 126 do Código Penal brasileiro, importar em violação à Convenção Interamericana de Direitos Humanos, tendo como base a decisão proferida pela Corte Interamericana de Direitos Humanos no caso “Artavia Murillo vs. Costa Rica”. Além disso, buscar-se-á investigar se a Corte pode verificar a compatibilidade em tese de lei interna em detrimento da própria Convenção, analisando-se a possibilidade de responsabilização de Estado signatário do Pacto de San Jose da Costa Rica por editar ou cumprir legislação contrária ao Tratado, igualmente levando-se em consideração a jurisprudência do tribunal interamericano de proteção aos direitos humanos. Analisando-se os precedentes da Corte, deduz-se que a criminalização do aborto no Brasil é incompatível com a Convenção Interamericana de Direitos Humanos, bem como que há a possibilidade de o Estado brasileiro ser responsabilizado pela manutenção e aplicação desta legislação, inclusive sendo obrigado a compatibilizar sua legislação em detrimento da Convenção Interamericana.
