Investigar-pensar desde los Estados del Arte: punto de partida Plantear problemas
Authors: Castillo Guzmán Rosaura , Fabila Echauri Angélica María , Pérez Morales Flor De Liz
Published: April 2019

La investigación y el pensamiento como dualidad, deben ser consideradas como fuente para la creación de ideas para ser investigadas; lo anterior recobra fuerza cuando reconocemos que tan importante es enseñar a investigar a los estudiantes universitarios, lo que implica entonces que alguien debe hacer esa tarea primordial.
En las aulas quien enseña a investigar es el docente responsable de aquellas asignaturas que, desde el currículo, marcan esa encomienda; hecho que parece oponerse a la premisa que en más de una ocasión hemos escuchado: se enseñanza a investigar investigando. La incertidumbre del encuentro entre docente-experto y aprendiz-novato en el aula para enseñar y aprender a investigar es una de las discusiones que permiten reflexionar que, si bien existen argumentos para sostener que se enseña a investigar investigando, es igualmente válido considerar que enseñar a pensar una idea para investigar y elevarla a la categoría de problema, se puede hacer desde el aula.
Desde la óptica de las autoras, una estrategia para enseñar y aprender a investigar pueden ser los estados del arte ya que, el encuentro que el aprendiz-novato tiene con las ideas de otros, que ante su mirada son investigadores-expertos, genera la posibilidad de activar su pensamiento y abrir perspectivas alternas que le conduzcan a superar la incertidumbre que presenta siempre el asunto a investigar, ampliando así la experiencia que tiene como referente para hacer investigación. Pensar una idea es una tarea que debe colocarse en el centro de quien enseña a investigar en el aula.

Systematic Mapping Study of Academic Engagement in MOOC
Authors: Guajardo Leal Brenda Edith , Navarro-Corona Claudia , Valenzuela González Jaime Ricardo
Published: April 2019

MOOCs are presented as an affordable and easily accessible modality that offers the opportunity to democratize education in our time; however, this convenience training favors a low completion rate of the participants. Faced with this situation, scholars have suggested that it is necessary to deepen the construct of academic engagement, a concept that has been addressed in the study of face-to-face training, to better understand how students participate in this educational modality. This article systematically explores the existing literature, in the period of 2015-2018, about the construct of academic engagement in online, massive and open learning courses, through a Systematic Mapping of Literature, a method which aims to identify the characteristics of production in a given subject. The results show that there is a considerable increase in published articles that associate academic engagement and MOOCs, mainly from the United States, Australia, and the United Kingdom. Most of the mapped publications employ qualitative methods, with an exploratory approach, although there are several correlational studies. The study of participation patterns and instructional design appear as the main topics of interest in the field. In addition to providing a general overview of production on the subject, the research provides accurate information that will identify works for more in-depth reviews. Thus, it also offers a replicable and flexible literature search method for different research interests.
From Finding a Niche to Circumventing Institutional Constraints
Authors: Jordan Katy
Published: April 2019

Academics are increasingly encouraged to use social media in their professional lives. Social networking sites are one type of tool within this; the ability to connect with others through this medium may offer benefits in terms of reaching novel audiences, enhancing research impact, discovering collaborators, and drawing on a wider network of expertise and knowledge. However, little research has focused on the role of these sites in practice, and their relationship to academics’ formal roles and institutions. This paper presents an analysis of 18 interviews carried out with academics in order to discuss their online networks (at either Academia.edu or ResearchGate, and Twitter) and to understand the relationship between their online networks and formal academic identity. Several strategies underpinning academics’ use of the sites were identified, including: circumventing institutional constraints, extending academic space, finding a niche, promotion and impact, and academic freedom. These themes also provide a bridge between academic identity development online and institutional roles, with different priorities for engaging with online networks being associated with different career stages.
Octennial Review (2010-2018) of Literature on M-Learning for Promoting Distributed-Based Medical Education in Sub-Saharan Africa
Authors: Yunusa Abdullahi Abubakar , Bin Umar Irfan Naufal , Bervell Brandford
Published: April 2019

Medical education in Africa is in desperate need of reforms, evident in widespread diseases, and an inability to mobilise and train the required medical workforce to deal with these health issues. However, the exponential rise in the use of mobile technologies due to the spread of the Internet and increased telecommunication networks offer an opportunity for the transformation of medical education and practice through the deployment of mobile devices as a medium for learning and conveying health care services to the remote and resource-constrained locations of Sub-Saharan Africa (SSA). This paper reviewed articles on the affordances of m-learning for distributed medical education in SSA published between 2010-2018. Results from 18 articles identified in the review revealed a slow-paced ascendancy of practice and research in the field; it further exposed competing priorities, infrastructural deficit, and chronic workforce shortages as the bane of m-learning implementation in the subregion. This paper makes recommendations that will enhance the growth of mobile-based distance medical education and practice in SSA.
Quality Frameworks and Learning Design for Open Education
Authors: Stracke Christian M.
Published: April 2019

This article discusses the need to innovate education due to global changes to keep its status as a human right and public good and introduces Open Education as a theory to fulfil these requirements. A systematic literature review confirms the hypothesis that a holistic quality framework for Open Education does not exist. For its development, a brief history and definition of Open Education are provided first. It is argued that Open Education improves learning quality through the facilitation of innovative learning designs and processes. Therefore, sources of learning quality and dimensions of quality development are discussed. To support the improvement of the learning quality and design of Open Education, the Reference Process Model of ISO/IEC 40180 (former ISO/IEC 19796-1) is introduced and modified for Open Education. Adapting the three quality dimensions and applying the macro, meso, and micro levels, the OpenEd Quality Framework is developed. This framework combines and integrates the different quality perspectives in a holistic approach that is mapping them to the learning design, processes, and results. Finally, this article illustrates potential adaptations and benefits of the OpenEd Quality Framework. The OpenEd Quality Framework can be used in combination with other tools to address the complexity of and to increase the quality and impact of Open Education. To summarize, the OpenEd Quality Framework serves to facilitate and foster future improvement of the learning design and quality of Open Education.
THE IMPLEMENTATION OF INTERNATIONAL ARBITRATION DECISIONS IN INDONESIA AND SOME FOREIGN COUNTRIES
Authors: Harahap Panusun
Published: April 2019

An international arbitration award handed down in a territory of a given country may be applied for in another territory, provided that it is a party to the 1958 New York Convention on the Recognition and Implementation of the Convention on the Recognition and Enforcement of Foreign Arbitral Awards and between those countries there are bilateral or multilateral agreements on the recognition and execution of international arbitration decisions. An arbitral award, as well as a judge's verdict may actually be voluntary by the loser or debtor. If the verdict has been executed in good faith by the losing party, or in other words his accomplishments have been met with good faith, then the problem is solved. It is not uncommon, however, that although the verdict is already in place, the losing party does not want to execute the verdict voluntarily. In this case the winning party or the creditor may submit an application to the Chairman of the Central Jakarta District Court for the international arbitration award to be executed by force (execution forcee).
SOWING GM CROPS: POPULATING BIOETHICS IN THE MALAYSIAN BIOSAFETY ACT 2007 THROUGH PUBLIC PARTICIPATION
Authors: Idris Siti Hafsyah
Published: April 2019

The bioethical issue is one of the concerns on genetically modified (GM) crops. One of the features to acknowledge this bioethical issue is through public participation. Through public participation, any concerns relating to the application and the release of GM crops could be integrated in the biosafety decision making process. The role of public participation is essential as it is a foundation of responsible democratic governance. It advocates public consultations by creating opportunities for transparency, informed and representative decision-making processes. This paper appraises the provision on public participation in the Malaysian Biosafety Act 2007 as to the extent to which bioethical issues could be integrated in the biosafety decision making process. The paper also proposes suggestions on good governance of public participation based on the relevant international legal agreements so that it is properly enforced and serves the desired objective of Biosafety Act 2007.
THE APPLICABILITY OF ARTICLE 4 OF ANTI-CORRUPTION LAW AND THE THEORY OF TORT
Authors: Purwoleksono Didik Endro
Published: April 2019

Article 4 of the Indonesian Corruption Law stipulates that the return of state financial losses does not eliminate the criminalization of the perpetrators of criminal acts as referred to in Article 2 and Article 3. What about the suspects or defendants who return the results of corruption related to the theory illegitimacy? There are two theories about the illegitimacy which are; the theory of illegitimacy against the formal law and the theory of illegitimacy against the material law. The theory of illegitimacy against the formal law, providing an understanding that an action, act, or activity is said to be against the law when against the rules set in the law. While through the Decision of the Supreme Court, Indonesia adheres to this theory. According to this theory, an action, act, or activity is said to be against the law when it is against the rules established in the law and according to the conditions is a disgraceful act or illegal. The decision of the Supreme Court provides the criteria for the loss of unlawful nature because of the factors of the state not being harmed, the society served and the defendant not making a profit. With the enactment of this theory, the existence of Article 4 of the Indonesian Corruption Law, becomes invalid with the condition that the results of corruption and its benefits have been returned by the perpetrators of corruption.
Aplikasi Mikoriza Arbuskula Untuk Meningkatkan Serapan Fosfat, Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium ascalonicum L.)
Authors: Rahman Muhammad Mujibur , Saidy Akhmad Rizalli , Nisa Chatimatun
Published: April 2019

One of the problems in phosphate nutrient fertilization is a low level of efficiency, so the application of arbuscular mycorrhiza is often done to increase phosphate uptake. In this study mycorrhizal was applied to shallots which were given P fertilizer to assess the effect of mycorrhizal applications on growth, yield, and phosphate uptake. This research was carried out at the Faculty of Agriculture's Greenhouse of the University of Lambung Mangkurat Banjarbaru from March to May 2016. The seed of shallot was grown on 5 kg of soil and quartz sand (3:1) fertilized by P (0, 50, 100, 150, 200 and 250 kg SP-36 ha-1) and applied with mycorrhiza (without and with 10 g of plant-1 mycorrhizal inoculum) at planting. The observations made after 75 days after planting showed that the application of arbuscular mycorrhiza was effected to improve several observation variables, namely plant dry weight, bulb dry weight, phosphate nutrient uptake, and phosphate efficiency. The application of mycorrhiza at phosphate doses of 250 kg SP-36 ha-1 can increase plant dry weight by 97% and bulb dry weight by 203% compared to without mycorrhiza. Whereas the application of mycorrhiza at a phosphate dose of 100 kg SP-36 ha-1 is the best and most efficient treatment to increase phosphate nutrient uptake and phosphate efficiency. The results of this study show that the application of mycorrhizal can increase nutrient uptake of phosphate which ultimately increases the growth and production of shallot plants.

Published: April 2019

Forest resources can be utilized through various activities in the land-based sector, including forestry, plantations, and mining. The implications of the issuance of various permits are indicated to cause changes in the area of forest and land cover. This paper aims to analyze and explain the implications of the various land-based sector licenses that have been issued by the local government and the central government on the condition of forest areas in Riau Province. The research method was carried out with qualitative descriptive analysis, through interviews, spatial analysis, and review and tracking documents. The results of the study showed that during the period 1986-2017 there had been a change in the area of forest area and land cover. The biggest changes in forest areas occur due to the conversion of forest areas into plantations, while the largest land cover changes in successive classes are land cover for plantations (Pk), forest plantations (Ht) and mining (Pn). Some of the recommendations that we propose are the temporary dismissal of licenses in the Riau forest area, the rearrangement of all licenses related to forest areas, increasing integrity and willingness of all parties in Riau and the central government in sustainable forest management.

Authors: Hadi Syahiful , Suryajaya Suryajaya , Abdullah Abdullah , Kissinger Kissinger
Published: April 2019

Urea-hydroxyapatite can be used as fertilizer which was efficient and environmentally friendly. The variation of Ca(OH)2 in the urea-hydroxyapatite’s synthesis and its characterization would provide information for manufacturing slow release fertilizer. The material used were urea (99.5 %); Ca(OH)2; H3PO4 0.67 M and distilled water. The synthesis technique used in this study is bottom-up with Ca(OH)2 variation of 6, 8, 10 and 12 grams. The results of the synthesis with 6 grams of Ca(OH)2  was not able to produce sediment powder. The results of the Scanning Electron Microscopy (SEM) showed that the urea packaging with hydroxyapatite was better for variations of Ca(OH)2  8 grams and 10 grams. The results of the Energy Dispersive X-Ray Spectrometry (EDX) showed more elemental composition in the variation of Ca(OH)2  8 grams and 10 grams which were 35.7 Wt% and 40.4 Wt%. The results of the Fourier Transform Infrared Spectrometer (FTIR) showed that the variation of Ca(OH)2  8 gram has a good bonding of urea and hydroxyapatite. The Particle Size Analyzer (PSA) measurement for all samples of urea-hydroxyapatite yielded the particle size of about 0.5–2.5 mm and 10–15 mm for urea and hydroxyapatite, respectively. As a conclusion, the variation of Ca(OH)2  8 grams could be recommended as a reference in the composition of urea-hydroxyapatite fabrication for slow release fertilizer.

UMA IGREJA COM ROSTO AMAZÔNICO: MEMÓRIA E PROFECIA A PARTIR DO CONTEXTO BRASILEIRO
Authors: Murad Afonso
Published: April 2019

A Amazônia tem despertado interesse no mundo, devido às peculiarida­des do seu bioma e às suas múltiplas etnias, culturas e religiões. O Papa Francisco convocou um Sínodo especial: “Amazônia. Novos Caminhos para a Igreja e para uma ecologia integral”. Corre-se o risco de se desconhecer a longa caminhada já realizada pelas igrejas da região e não se aprender com a sua história. Então, o artigo visa mostrar como nos últimos anos já se desenvolveu na região uma Igreja com rosto amazônico, que promoveu o cuidado da Casa Comum.

Published: April 2019

The main purpose of this paper is to introduce a new class of $q$-Hermite-Fubini numbers and polynomials by combining the $q$-Hermite polynomials and $q$-Fubini polynomials. By using generating functions for these numbers and polynomials, we derive some alternative summation formulas including powers of consecutive $q$-integers.  Also, we establish some relationships for $q$-Hermite-Fubini polynomials associated with $q$-Bernoulli polynomials, $q$-Euler polynomials and $q$-Genocchi polynomials and $q$-Stirling numbers of the second kind.
Modeling Efficiency of Energized Fluid Fracturing in Tight Gas Formations
Authors: Wilk Klaudia
Published: April 2019

Hydraulic fracturing is the most effective method of stimulation for hydrocarbon reservoirs. However the use of water-based fracturing fluids, can be a problem in water-sensitive formations due to the permeability damage hazard caused by clay minerals swelling. For this reason, the foamed fracturing fluids with addition of natural, fast hydrating guar gum were examined. The rheology and filtration coefficients of foamed fracturing fluids were examined and compared to the properties of conventional water-based fracturing fluid. Laboratory results provided the input for numerical simulation of the fractures geometry for water-based fracturing fluids and 50% N2 foamed fluids. The results show, that the foamed fluids were able to create shorter and thinner fractures compared to the fractures induced by the non-foamed fluid. The simulation proved that the concentration of proppant in the fracture and its conductivity are similar or slightly higher when using the foamed fluid. Moreover such fluids are able to significantly reduce the amount of water necessary for fracturing treatments, limiting clay minerals swelling, and reducing the reservoir permeability damage. The foamed fluids, when injected to the reservoir, provide additional energy, that allow for more effective flowback, and maintain the proper fracture geometry and proppant placing. The results of laboratory work in combination with the 3D simulation showed, that the foamed fluids have suitable viscosity which allows opening the fracture, and transport the proppant into the fracture, providing successful fracturing operation.
Modeling Dislocation Contrasts Obtained by Accurate-Electron Channeling Contrast Imaging for Characterizing Deformation Mechanisms in Bulk Materials
Authors: Kriaa Hana , Guitton Antoine , Maloufi Nabila
Published: April 2019

Electron Channeling Contrast Imaging (ECCI) is becoming a powerful tool in Materials Science such as for characterizing deformation defects. Dislocations observed by ECCI in Scanning Electron Microscope, exhibit several features depending on the crystal orientation relative to the incident beam (white/black line on a dark/bright background). In order to bring new insights concerning these contrasts, we report an original theoretical approach based on the dynamical diffraction theory. Our calculations led, for the first time, to an explicit formulation of the backscattered intensity as function of various physical and practical parameters governing the experiment. Intensity profiles are modeled for dislocations parallel to the sample surface for different channeling conditions. All theoretical predictions are consistent with experimental results.
The Role of Marketing in Cultural Institutions in the Context of Assumptions of Sustainable Development Concept—The Example of Poland
Authors: Sobocińska Magdalena
Published: April 2019

Development of both marketing and culture sector has a multi-directional nature showing relationships with the concept of sustainable development that should be considered on various levels of management of cultural sector, i.e. on the level of cultural policy of the state or region, and on micro-scale – in cultural institutions. This is because not only natural environment, economy and technology, but also society and culture constitute the area of sustainable development.   Considering the assumptions of sustainable development by cultural institutions is related to implementing in this sphere the marketing concepts that are the expression of adoption of market orientation (on culture participant). The objective of the paper is to show the role of marketing in cultural institutions in the context of assumptions of sustainable development concept. The paper is based on literature studies and results of empirical research of quantitative character, which was conducted on a sample of 451 people managing cultural  institutions in Poland. The research included general managers, managers and artistic directors, managers of marketing, promotion and sales departments, as well as owners of cultural institutions. Analysis of research results shows that culture participant has the highest position among groups of consumers of actions conducted by cultural institutions and development of offer diversity, comprised in the concept of sustainable development, emerges as factor stimulating development of culture market that is closely related to growth of the quality of cultural institution offer.
Research on Recognition Technology of Aluminum Profile Surface Defects Based on Deep Learning
Authors: Wei Ruofeng , Bi Yunbo
Published: April 2019

Aluminum profile surface defects can greatly affect the performance, safety and reliability of products. Traditional human-based visual inspection is low accuracy and time consuming, and machine vision-based methods depend on hand-crafted features which need to be carefully designed and lack robustness. To recognize the multiple types of defects with various size on aluminum profiles, a multiscale defect detection network based on deep learning is proposed. Then, the network is trained and evaluated using aluminum profile surface defects images. Results show 84.6%, 48.5%, 96.9%, 97.9%, 96.9%, 42.5%, 47.2%, 100%, 100%, 43.3% average precision(AP) for the ten defect categories, respectively, with a mean AP of 75.8%, which illustrate the effectiveness of the network in aluminum profile surface defects detection. In addition, saliency maps also show the feasibility of the proposed network.
Multi-Factor Coupling Model of Concrete Chloride-Ion Diffusion Coefficient in a Salt Lake
Authors: Zhang Liming , Yu Hongfa , Li Jia
Published: April 2019

Immersion in salt-lake solution was adopted to periodically test the concrete chloride-ion diffusion coefficient. The regression analysis was also completed. Also investigated was the time-dependent law of concrete chloride-ion diffusion coefficient with time. The influence of chloride-ion concentration in solution, water-to-cement ratio, and corrosion time on the largeness and accumulation rate of the concrete chloride-ion diffusion coefficient was also analyzed. Test results show that the concrete chloride-ion diffusion coefficient gradually decreased with increasing time and increased with increasing chloride-ion concentration in a salt lake . Taking into account the influence of factors such as water–binder ratio, chloride-ion concentration, and time-varying characteristics, a multi-factor calculation model for the concrete chloride-ion diffusion coefficient was established. Combining the prediction results and the measured data reported in this paper, the effectiveness and applicability of the established concrete chloride-ion diffusion coefficient calculation model were compared and verified, and the durability design and service life of a concrete structure under cool chlorine were compared. The results of analysis provide important boundary conditions.
A Complete Biological Theory of Sleep
Authors: Rappoport Ari
Published: April 2019

Sleep is still considered a mystery, despite intense scientific investigation. Here we present the first complete biological theory of sleep. The role of sleep is to restore the optimal homeostatic state, which is essential for tissue performance and health. Non-rapid eye movement sleep (NREMS) restores cortical and most other brain neurons, via relaxed global activity managed by thalamocortical circuits. The role of REM sleep is to restore acetylcholine (ACh) neurons, which support focused responses and hence cannot participate in global oscillations. Sleep enhances learning and memory via state restoration and ACh-affected paths. NREMS induces a lack of consciousness because global synchronous activity prevents focused responses, which are essential for consciousness. Dreams result from focused neural firing during sharp-wave ripples and REMS, and have a sense of reality because they involve the same neurons representing focused perceptual responses during wake. Anesthetics utilize a variety of mechanisms that prevent focused responses.

Authors: Masłowski Mateusz , Kasza Piotr , Czupski Marek , Wilk Klaudia , Moska Rafał
Published: April 2019

This paper concerns the effect of proppant embedment related with hydraulic fracturing treatment. This phenomenon occurs if the strength of the reservoir rock is lower than proppant grains. The aim of the research is laboratory determining the loss of width of the proppant pack built of light ceramic grains. The laboratory simulation of the embedment phenomenon was carried out for a shale rock on a hydraulic press, in a specially prepared for this purpose a heated embedment chamber. Tests were conducted at high temperature and axial compressive stress conditions. The surfaces of the cylindrical core plugs (fracture faces) were imaged under an optical microscope equipped with 3D software. The fracture faces were examined and compared before and after the embedment phenomenon. The analysis of the obtained images of the fracture face were made based on the research method of the embedment phenomenon developed at Oil and Gas Institute-NRI. On the basis of laboratory tests, the parameters characterizing the embedment phenomenon were collected and discussed. In addition, the percentage reduction in the width of the proppant pack was determined.
