LA VELOCIDAD DE LA ONDA DE CORTE NO ES SUFICIENTE PARA CLASIFICAR EL SUELO
Authors: Aguiar Roberto , Espinosa A , Carrión J , Zambrano V. 
Published: April 2018

Después del terremoto del 16 de abril de 2016, que tuvo una magnitud de 7.8; se realizó estudios geofísicos en 17 lugares de la ciudad de Bahía de Caráquez, para emitir un diagnóstico sobre la vulnerabilidad sísmica de algunos edificios; 13 de los 17 suelos analizados clasificaron como perfiles tipo “C” y 4 como tipo “D”. Pero la velocidad de la onda de corte de los 4 sitios con suelo “D”, es alta, de tal manera que se puede indicar que los 17 lugares donde se encontraban y se encuentran estructuras importantes eran suelos resistentes, de acuerdo a la clasificación de la Norma Ecuatoriana de la Construcción de 2015. Entonces.En este artículo, se presenta la relación que existe entre la Velocidad de la Onda de Corte en los primeros 30 metros, con la frecuencia dominante del suelo y con la amplitud del Espectro de Fourier asociada a la frecuencia dominante, de los suelos de Bahía de Caráquez. De igual manera se compara estos parámetros geofísicos con los resultados de estudios similares realizados con dos bases de datos; la primera con sismos registrados en Japón y la segunda con sismos de la base de datos NGA-West 2.Finalmente se concluye que en la clasificación de los suelos de la NEC-15 basada más en la Velocidad de la Onda de Corte debe ser complementada con la inclusión del período de vibración del suelo o con la amplitud máxima del Espectro de Fourier.
USO DE RESIDUOS CERÁMICOS COMO SUSTITUTO DEL CEMENTO PARA FABRICACIÓN DE MORTEROS
Authors: Viera Paulina , Chicaiza Carla 
Published: April 2018

En la presente investigación se estudia el uso de desechos cerámicos triturados, obtenidos en una fábrica de Quito, como material sustituto de cemento para la fabricación de morteros. Se compara la resistencia a compresión del mortero elaborado con 100% de cemento y del elaborado con diferentes porcentajes de cerámica triturada (3%, 5%, 7%, 10%, 15%) en sustitución del cemento. Se observa que la resistencia es similar hasta porcentajes del 10% de cerámica triturada. Se concluye que el uso de desechos cerámicos permitiría reducir el costo de los morteros, manteniendo su resistencia. La caracterización de los materiales constituyentes del mortero y su resistencia se efectuó utilizando las normas de la ASTM (American Society Testing Materials) y NTE (Norma Técnica Ecuatoriana).

Published: April 2018

Abstract

Background: Learning Management Systems (LMS) represent one of the main technology to support learning in HE institutions. However, every educational institution differs in its experience with the usage of these systems. South East European University’s LMS experience is longer than a decade. From last year SEE – University is adopting Google Classroom (GC) as an LMS solution.

Objectives: Identifying factors which encourage LMS activities, with special emphasis on SEEU, might be of crucial importance for Higher Education academic leaders as well as software developers who design tools related to fostering LMS.

Methods/Approach: This paper introduces new approach of investigating the usage of LMS, i.e. identifying the determinants of increasing usage of LMS activities, by conducting empirical analysis for the case of SEEU. We apply appropriate estimation technique such as OLS methodology.

Results: Using SEEU Usage Google Classroom Report & Analysis Data for spring semester (2016–2017) and winter semester (2017–2018) - SUGCR dataset 2017, we argue that (i) LMS activities are affected by demographic characteristics and (ii) the students’ LMS usage is affected by level and resources of instructors’ LMS usage.

Conclusions: The empirical results show positive relationship between student and instructors’ LMS usage.

Published: April 2018

Abstract

Background: The intensity of innovation could often be crucial for further economic development of the regions. Science and technology are often seen as the key factor supporting innovation in the regions. Furthermore, we can assume that higher intensity of research activities could lead to better economic performance.

Objectives: Research aims to examine the link between the economic performance of the region and the intensity of science and technology activities, proxied by the share of employees in science and technology.

Methods/Approach: The analysis is based on panel data for NUTS2 regions of the European Union (EU) member states. We conducted correlation analysis, panel Granger causality tests and regression analysis.

Results: Our results suggest the existence of a significant positive correlation between GDP per capita and the share of employees in science and technology. Moreover, the regions with a higher intensity of science and technology activities are mostly characterized by relatively low unemployment rates.

Conclusions: Research activities are positive correlated with regional GDP and negatively correlated with unemployment. However, increasing the share of employment in science and technology beyond a certain turning point would not lead to any further positive effects on regional economic performance.
The Effect of Government Subsidy on Non-Technological Innovation and Firm Performance in the Service Sector: Evidence from Germany
Authors: Basit Shoaib Abdul , Kuhn Thomas , Ahmed Mumtaz 
Published: April 2018

Abstract

Background: To enhance the innovation activities at the firm level, government subsidies plays an important role.

Objectives: The objective of the study is to explore whether firms in service sector that receive government subsidies engage more in marketing and organizational innovation activities than their counterparts. Second, focusing on the subsidized firms in the service sector, the impact of innovations (marketing as well as organizational) on firm performance—measured as the probability of submitted copyright applications by firms, has been analyzed.

Methods/Approach: The propensity score matching approach and probit model have been used to analyze the innovation activities of subsidized and non-subsidized firms. The empirical analysis is based on the micro level data from Mannheim Innovation Panel, covering the Community Innovation Survey of 2011.

Results: Empirical results show that public subsidy has a significant positive effect on marketing and organizational innovation. In addition, within the firms that have received government subsidy, the impact of only marketing innovation is found to be significant on firm performance.

Conclusions: These findings employ that subsidized firms are more likely to perform better than their counterparts. Furthermore, public subsidy programs increase the probability of applying for a copyright in small and medium firms.

O MAU EMPREGO DAS EXCEÇÕES À REGRA DO CONCURSO PÚBLICO: UMA ANÁLISE DOS MUNICÍPIOS DE QUIXERAMOBIM E QUIXADÁ
Authors: Oliveira Lucas Brito de 
Published: April 2018

<p class="Estilopadro"><span>Constitui objetivo deste trabalho esclarecer o conceito e alcance do instituto do concurso público, bem como suas exceções e requisitos, pretendendo revelar se nos Municípios de Quixeramobim e Quixadá o mandamento constitucional é observado, e, em não sendo, analisar eventual improbidade e crime de responsabilidade por parte dos administradores municipais. Neste trabalho, empregar-se-á o método lógico dedutivo, baseado na realização de pesquisas em livros, artigos científicos, legislação e posicionamentos dos órgãos superiores, além da coleta e interpretação de dados fornecidos pelos municípios estudados, em uma abordagem quantitativa de seus vínculos com os servidores públicos, tudo por meio de proposições conclusivas, enfrentadas na conclusão. Como resultado do trabalho, infere-se que, nos entes políticos analisados, há desproporção entre os vínculos estabelecidos sob formas ordinárias de admissão de servidores, e os que representam exceções ao concurso público. Isto revela um mau emprego das exceções ao concurso público, o que constitui indícios de improbidade administrativa e crime de responsabilidade atribuíveis aos gestores municipais. </span></p>

Para tanto, a partir de uma pesquisa bibliográfica e jurisprudencial, busca-se nos pressupostos do direito internacional público e do direito constitucional, os elementos que fundamentam o necessário diálogo entre as ordens interna e externa e sua direta relação com a concretização do princípio <em>pro homine</em>. Nesse sentido, o trabalho abordará os aspectos gerais acerca da natureza jurídica dos tratados que versam sobre direitos humanos, à luz do novel processo constitucional de internalização desses diplomas normativos e o propício desenvolvimento de uma teoria de controle de convencionalidade, ampliando, ainda mais, o leque protetivo da força normativa da Constituição. Ao final, busca-se enfatizar o quanto é primevo a utilização dessa nova modalidade de controle no exercício da atividade jurisdicional. </span></p><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: center; line-height: normal;" align="center"><strong><span style="font-size: 12.0pt; font-family: 'Times New Roman',serif;">UMA ANÁLISE CRÍTICA DA TEORIA DO CONTROLE DE CONVENCIONALIDADE E SUA APLICAÇÃO NAS RECENTES JURISPRUDÊNCIAS DO STF</span></strong></p>
A Synergistic LUMO Lowering Strategy Using Lewis Acid Catalysis in Water to Enable Photoredox Catalytic, Functionalizing C-C Cross-Coupling of Styrenes
Authors: Speckmeier Elisabeth , Fuchs Patrick J. W. , Zeitler Kirsten 
Published: April 2018

Easy available alpha-carbonyl acetates serve as convenient alkyl radical source for an efficient, photocatalytic crosscoupling with a great variety of styrenes. Activation of electronically different alpha-acetylated acetophenone derivatives could be effected via LUMO lowering catalysis using a superior, synergistic combination of water and (water-compatible) Lewis acids. Deliberate application of fac-Ir(ppy)3 as photocatalyst to enforce an oxidative quenching cycle is crucial to the success of this (umpolung type) transformation. Mechanistic particulars of this dual catalytic coupling reaction have been studied in detail using both Stern-Volmer and cyclic voltammetry experiments. As demonstrated in more than 30 examples, our waterassistedLA/photoredox catalytic activation strategy allows for excess-free, equimolar radical cross-coupling and subsequent formal Markovnikov hydroxylation to versatile 1,4-difunctionalized products in good to excellent yields.

Published: April 2018

ABSTRAKPutusan Nomor 24/G/2013/PTUN.JKT merupakan putusan mengenai pembatalan keputusan penetapan tanah telantar yang berasal dari Hak Guna Usaha (HGU) atas nama PT SMG. Pokok sengketa yang menjadi perdebatan dan tafsir dalam gugatannya adalah pengertian tanah telantar dan mengenai surat peringatan sebagaimana diatur dalam Pasal 8 Peraturan Pemerintah Nomor 11 Tahun 2010 tentang Penertiban dan Pendayagunaan Tanah Telantar serta implikasi pasca pembatalan surat keputusan penetapan tanah telantar oleh pengadilan tata usaha negara. Rumusan masalah dalam penelitian ini adalah bagaimanakah penafsiran pengertian tanah telantar dan penafsiran mengenai surat peringatan dalam Putusan Nomor 24/G/2013/PTUN.JKT, serta apa implikasi pembatalan surat keputusan penetapan tanah telantar pasca Putusan Nomor 24/G/2013/PTUN.JKT? Melalui metode penelitian hukum normatif dengan pendekatan studi kasus dapat disimpulkan bahwa adanya perbedaan penafsiran mengenai pengertian tanah telantar terkait dengan frase “dengan sengaja” dan “tidak sengaja,” majelis hakim berpendapat bahwa hambatan pemanfaatan tanah karena menunggu proses permohonan pelepasan kawasan hutan dan permasalahan tata ruang serta kendala terhadap pembebasan lahan dan proses ganti rugi disimpulkan sebagai unsur ketidaksengajaan. Implikasi pembatalan surat keputusan penetapan tanah telantar adalah tidak dapat didayagunakan untuk kepentingan masyarakat dan negara.Kata kunci: surat keputusan penetapan, tanah telantar, putusan pengadilan. ABSTRACTDecision of State Administrative Court Number 24/G/2013/PTUN.JKT constitutes a ruling of the revocation of a derelict land settlement agreement derived from Cultivation Rights on behalf of SMG Company. The subject of the dispute debated in the interpretation of the lawsuit is the definition of derelict land and warning letters, as regulated in Article 8 of Government Regulation Number 11 of 2010 regarding Policies and Utilization of Derelict Land and the implications of post-revocation of derelict land stipulated decree by the Administrative Court. The formulation of the problem in this research is the interpretation of derelict land definition and warning letters in the Administrative Court Decision Number 24/G/2013/PTUN.JKT, as well as the implication of revocation of derelict land settlement agreement after the court decision issuance. Through normative legal research method with case study approach, it can be underlined that there is difference in interpretation of the definition of derelict land related to the phrase “intentionally” and “unintentionally”, in which the judges argue that barriers to land utility are the still-in-process request of forest areas acquisition, spatial problems and constraints to land acquisition, as well as the compensation process concluded as an element of inadvertence. The revocation of the settlement agreement makes it impossible to use the derelict land for benefit of the people and the state.Keywords: determination decree, derelict land, court decision.

Abstract
Hybrid materials with the metal matrix are important engineering materials due to their outstanding mechanical and tribological properties. Here are presented selected tribological properties of the hybrid composites with the matrix made of aluminum alloy and reinforced by the silicon carbide and graphite particles. The tribological characteristics of such materials are superior to characteristics of the matrix – the aluminum alloy, as well as to characteristics of the classical metal-matrix composites with a single reinforcing material. Those characteristics depend on the volume fractions of the reinforcing components, sizes of the reinforcing particles, as well as on the fabrication process of the hybrid composites. The considered tribological characteristics are the friction coefficient and the wear rate as functions of the load levels and the volume fractions of the graphite and the SiC particles. The wear rate increases with increase of the load and the Gr particles content and with reduction of the SiC particles content. The friction coefficient increases with the load, as well as with the SiC particles content increase.
