On uniform asymptotic risk of averaging GMM estimators
Authors: Cheng Xu , Liao Zhipeng , Shi Ruoyao
Published: July 2019

This paper studies the averaging GMM estimator that combines a conservative GMM estimator based on valid moment conditions and an aggressive GMM estimator based on both valid and possibly misspecified moment conditions, where the weight is the sample analog of an infeasible optimal weight. We establish asymptotic theory on uniform approximation of the upper and lower bounds of the finite‐sample truncated risk difference between any two estimators, which is used to compare the averaging GMM estimator and the conservative GMM estimator. Under some sufficient conditions, we show that the asymptotic lower bound of the truncated risk difference between the averaging estimator and the conservative estimator is strictly less than zero, while the asymptotic upper bound is zero uniformly over any degree of misspecification. The results apply to quadratic loss functions. This uniform asymptotic dominance is established in non‐Gaussian semiparametric nonlinear models.
A Flexible and Centralized Approach for Access Control in Heterogeneous IoT Environment
Authors: Colin Jean-Noël , Evrard Laurent
Published: July 2019

In this article, the researchers introduce a 3-level model for security access control that comes as an extension to ABAC. This extension augments its structural and hierarchical expressiveness allowing to define arbitrarily complex access control rules. The authors apply this model to IoT platforms and show how it fulfils security access control requirements of these platforms. Finally, a reference architecture is introduced for access control applied to connected objects and its implementation details are presented.
Using Data Analytics to Predict Hospital Mortality in Sepsis Patients
Authors: Alnsour Yazan , Hadidi Rassule , Singh Neetu
Published: July 2019

Predictive analytics can be used to anticipate the risks associated with some patients, and prediction models can be employed to alert physicians and allow timely proactive interventions. Recently, health care providers have been using different types of tools with prediction capabilities. Sepsis is one of the leading causes of in-hospital death in the United States and worldwide. In this study, the authors used a large medical dataset to develop and present a model that predicts in-hospital mortality among Sepsis patients. The predictive model was developed using a dataset of more than one million records of hospitalized patients. The independent predictors of in-hospital mortality were identified using the chi-square automatic interaction detector. The authors found that adding hospital attributes to the predictive model increased the accuracy from 82.08% to 85.3% and the area under the curve from 0.69 to 0.84, which is favorable compared to using only patients' attributes. The authors discuss the practical and research contributions of using a predictive model that incorporates both patient and hospital attributes in identifying high-risk patients.
The Role of Serious Gaming in Assisting Humanitarian Operations
Authors: Wang Yan , Lukosch Heide K. , Schwarz Philipp
Published: July 2019

Crisis response, including humanitarian operations, is a highly complex field and its effectiveness is challenged by the dynamic partnerships of organizations involved and critical field conditions. Serious gaming is recognized as an effective method for complex systems design and analysis. Given the criticality of complex humanitarian operations and the current challenges faced by humanitarians in crisis response, serious gaming could play an important role in this field. However, the full potential of serious gaming in humanitarian assistance has not been fully explored yet. This article examines the role of serious gaming in assisting humanitarian operations. A board game is developed and played to examine its role in facilitating requirement engineering and training for humanitarian missions. In the contribution, the authors show how they were able to address the vital challenges faced by humanitarian aid workers in crisis response. Additionally, the outcomes of game sessions and their implications for humanitarian operations of the future was discussed.
Experimental Study on CFRP-PVC Confined RAC under Axial Compression
Authors: Lu Jie Qun , Tian Yuan , Chen Jia Geng , Zhu Chen Yu , Zeng Fu Yuan , Yang Jin Cheng , Wang Wei
Published: July 2019

Compared with natural aggregate concrete (NAC), the cylinder compressive strength and elastic modulus of Recycled aggregate concrete (RAC) are decreased, but the brittleness is increased. The axial compression performance of RAC can be improved by external confinement. In this paper, the effects of Polyvinyl chloride (PVC) pipe confinement and composite confinement of PVC pipe and Carbon Fiber Reinforced Polymer (CFRP) on the axial compression performance of RAC were investigated. The results showed that with the increase of the replacement rate of recycled coarse aggregate, the cylinder compressive strength, peak strain and elastic modulus of RAC were decreased; PVC pipe confinement could significantly improve the cylinder compressive strength, peak strain and elastic modulus of RAC; the CFRP could further improve the cylinder compressive strength and elastic modulus of PVC-RAC to a certain extent, and could significantly enhance the peak strain of PVC-RAC. PVC pipe and CFRP-PVC pipe confinement could improve the axial compression performance of RAC more effectively than NAC. Consequently, PVC pipe and CFRP-PVC pipe confinement could reduce the influence of recycled aggregate (RA) quality on variability of RAC axial compression performance.
Physical, Mechanical and Chemical Properties of Dewatered Sewage Sludge and Red Gypsum Mix as a Potential Recycling Product
Authors: Rosli Nor Azalina Binti , Aziz Hamidi Abdul , Selamat Mohamad Razip , Lim Leonard Lik Pueh
Published: July 2019

This paper aims to present the characteristic of dewatered sewage sludge (SS) and red gypsum (RG) to determine their recycling potentials into a valuable product. The materials were characterized based on their physical-mechanical-chemical properties and morphology. The results showed that dewatered sewage sludge and red gypsum could complement each other when used together to form a new material the merits of which will be investigated in subsequent studies. RG has a better performance in term of plasticity and strength than SS due to fines content in the former and therefore its ability to retain moisture that contributes to cohesion between particles. Fine prisms and closer packing particles add strength in RG leading to higher resistance in compression. Unlike RG, SS has coarser particle and more voids causing it to lose the moisture content and becomes easily disintegrated. Chemical compositions of RG and SS as determined by XRF demonstrated a significant amount of CaO in the former and SiO2 in the latter; the formation of hydrated products in the form of CSH and CAH gel from hydration or pozzolanic reaction contributes to strength improvement of the SS.

Authors: Alguno Arnold C. , Emphasis Katherine M. , Potestas Melchor J. , Vequizo Reynaldo M. , Capangpangan Rey Y. , Linog Bernabe L. , Basilia Blessie A.
Published: July 2019

We report on the growth of zinc oxide/polyaniline (ZnO/PANI) nanocomposites deposited on platinum (Pt)–coated glass substrate via chemical bath deposition and dip–casting technique is reported. Scanning electron micrographs of the nanocomposites revealed that etching of ZnO nanorods takes place during growth which turn into plate–like and distorted nanostructures. We found out that increasing the concentration of NH4OH triggered increase in nanostructure diameter. The surface morphology of nanocomposites significantly changed as the molar concentration of NH4OH precursor varies. Fast fourier transform infrared spectroscopy results showed the interaction of ZnO and PANI by observing the shift of peaks to the higher wavenumbers. The measured optical band gap of the nanocomposites are in good aggreement with the reported values. This result indicates that the grown ZnO/PANI nanocomposites is a good material for solar cell device.

Authors: Petrucca Andrea , Alari Antonella , Papadopoulou Styliani , Petrucci Crisitina , Santino Iolanda
Published: July 2019

Measles continue to be a major public health issue worldwide with high morbidity and mortality rates. The disease is still endemic in Europe and during 2017 a vast outbreak was described in Italy, Romania and Hungary, which led to thousands of new cases and several deaths. In Italy, 3931 confirmed cases of measles were reported to the Italian national surveillance system from many Italian administrative regions; Lazio, in central Italy, exhibited the highest number of infected patients 1322 (33.63%) and as well as the highest incidence. In this study, we describe the results of a retrospective analysis, carried out during 2016 and 2017, concerning the measles antibody prevalence in patients and healthcare workers attending the Sant’Andrea Hospital of Rome (Lazio). A total of 94 patients (median 30 years of age) were screened in 2016, and 316 (median 40 years of age) during 2017, with an increase of 236% compared to previous year. During 2017, 41 confirmed cases of measles were reported while none in 2016 (P<0.007), and we found a suboptimal immunization coverage in our cohort of patients. Furthermore, measles surveillance of Sant’Andrea healthcare workers during the study period involved 208 personnel units (median >47 years of age) and only one confirmed measles infection was recorded in 2017. These results suggest that there is still an unvaccinated portion of the adult population, who sustain the endemic circulation of measles in Italy. In addition to reach herd immunization on children of 2 years old, catch-up vaccination campaign targeting adult population in Italy and other European countries needs to be implemented to prevent future measles outbreak.
The global Mycobacterium chimaera outbreak
Authors: Tortoli Enrico
Published: July 2019

Infections due to Mycobacterium chimaera associated with a heater-cooler device used during the open-heart surgery have been reported worldwide. These cases represent the first outbreak caused by a non-tuberculous mycobacterium at a global level. Salient features of the infection are long latency and high mortality. Different aspects of the M. chimaera outbreak, from the first detected cases to the present burden are reviewed in this study. Although the source has been found and thwarted, new cases continue to be detected due to the late manifestation of symptomatology. The treatment remains poorly effective and mortality is around 50%.

Distinguishing the virtuous city of Alfarabi from that of Plato in light of his unique historical context
Authors: Ali Ishraq , Mingli Qin
Published: July 2019

There is a tendency among scholars to identify Alfarabi’s political philosophy in general and his theory of the state in particular with that of Plato’s The Republic. Undoubtedly Alfarabi was well versed in the philosophy of Plato and was greatly influenced by it. He borrows the Platonic concept of the philosopher king and uses it in his theory of the state. However, we argue that the identification of Alfarabi’s virtuous city with that of Plato’s The Republic is an inaccurate assessment as it involves overlooking Alfarabi’s unique religiopolitical context. Alfarabi was a Muslim political philosopher, and the present article intends to understand Alfarabi’s theory of the state in light of his historical context. The article shows that, viewed through the prism of Islamic religion and political history, Alfarabi’s virtuous city seems distinct from that of Plato’s The Republic.
South African students' perceptions of the usefulness of a management accounting simulation
Authors: Rudman Riaan J. , Kruger-Van Renen Wandi
Published: July 2019

Professional bodies such as the International Federation of Accountants and related bodies such as the South African Institute of Chartered Accountants require Information Technology (IT) to be integrated with the professional subjects, which includes Management Accounting. This has been a recent development in the training of professional accountants. Historically, universities have mainly focused on numerical problem-solving, but there has been a shift in focus from numerical problem-solving only to integrating numerical problem-solving with strategic and business matters.The Department of Accounting at Stellenbosch University developed a management accounting simulation in the form of a business plan project covering the entire process of launching a new business idea. Students select a new business concept, research the viability thereof and prepare various sets of financial information and a business plan. The learning objective of the simulation is to integrate management accounting with IT, and expose students to a real-life business experience.A questionnaire was developed to evaluate students’ perceptions of the benefits and disadvantages of a simulation, including a business plan project as a teaching tool. Responses to the appropriateness of a simulation as a teaching tool were favourable. Respondents felt that it helped them to understand both management accounting as well as IT functionalities better.
Emerging trends in reporting: An analysis of integrated reporting practices by South African top 40 listed companies
Authors: Marx Ben , Mohammadali-Haji Ahmed
Published: July 2019

Companies should behave as responsible corporate citizens and conduct their business in a manner that meets existing needs without compromising the ability of future generations to meet their needs. Thus they should protect, enhance and invest in the wellbeing of the economy, society and the natural environment in which they do business. Annual reporting format of financial reporting does not take cognisance of stakeholders’ needs in this regard, and there is a need for reporting that brings together financial, sustainability, management commentary and governance aspects in a coherent, simplified and concise manner.The objective of this paper is twofold: it aims, firstly, to provide a brief overview of the development of integrated reporting, and, secondly, to provide evidence regarding the integrated reporting practices at the largest listed companies in South Africa. This is done through a literature review of current corporate governance and sustainability developments, supported by empirical evidence obtained from assessing, through content analysis, the integrated reporting practices of the top 40 companies on the Johannesburg Securities Exchange, South Africa. The study found that although integrated reporting is evolving, inconsistencies still exist regarding the process to follow, format, content, and value thereof. The study is of specific relevance for Africa with its rich mineral resources, as it is of vital importance that companies that do business on the continent behave as responsible corporate citizens, respect the environment and society, and provide accurate, reliable and credible reporting on their financial and sustainability performance to all of their stakeholders in a simplified and integrated manner.

Published: July 2019

Sanitary landfill is the most disposal method for urban solid waste. However, in the process of organic matter degradation, a dark-colored liquid with high potential for polluting is produced, necessitating an efficient treatment before its discharge into watercourses. Several technologies can be used in the treatment, such as biological and physico-chemical systems. The activated carbon produced from agricultural residues - rice husk ash (RHA), appears as an alternative treatment, mainly for color reduction in landfill leachate. This study determined the best operational condition for the slurry treatment using a fixed-bed column. The column was filled with activated RHA and support material (sand). The column heights studied were 5 cm (C1) and 20 cm (C2) of adsorbent. The column with 20 cm of RHA and sand intercalated with the coal layer showed better efficiency in removal of the chemical oxygen demand (COD), with COD removal efficiency of 88.91% and rupture time of 120 min. The removal of apparent color was 87.40% with the rupture time of 40 min and true color removal of 86.64% with rupture time of 50 min. Activated rice husk ash was shown to be promising for post-treatment of the leachate with substantial efficiency.
Model theory and Rokhlin dimension for compact quantum group actions
Authors: Gardella Eusebio , Kalantar Mehrdad , Lupini Martino
Published: July 2019

We show that, for a given compact or discrete quantum group

G

, the class of actions of

G

on C*-algebras is first-order axiomatizable in the logic for metric structures. As an application, we extend the notion of Rokhlin property for

G

-C*-algebra, introduced by Barlak, Szabó, and Voigt in the case when

G

is second countable and coexact, to an arbitrary compact quantum group

G

. All the preservation and rigidity results for Rokhlin actions of second countable coexact compact quantum groups obtained by Barlak, Szabó, and Voigt are shown to hold in this general context. As a further application, we extend the notion of equivariant order zero dimension for equivariant *-homomorphisms, introduced in the classical setting by the first and third authors, to actions of compact quantum groups. This allows us to define the Rokhlin dimension of an action of a compact quantum group on a C*-algebra, recovering the Rokhlin property as Rokhlin dimension zero. We conclude by establishing a preservation result for finite nuclear dimension and finite decomposition rank when passing to fixed point algebras and crossed products by compact quantum group actions with finite Rokhlin dimension.

XForms Space Invaders
Authors: Chelsom John J.
Published: July 2019

The Model-View-Controller (MVC) paradigm is a design pattern for creating applications in which: the View (web page) interacts with the user; the Model controls manipulation of the data; and the Controller orchestrates the work of the view and the model. Implementing the classic arcade game Space Invaders in an XForms workbench proved to be a successful testbed for this approach. Key functionalities required for Space Invaders are an application “heartbeat” to control the speed/progression of the invaders; animated graphics for the invaders, the Mystery Ship, and laser fire; and the user-controlled laser cannon. The workbench was implemented using Orbeon Forms, an open source framework which supports XForms 1.1 with a number of custom extensions, including Javascript actions, Attribute Value Templates on XHTML elements, and listeners for “keypress” events. Most of the extensions required are included in the draft XForms 2.0 specification (albeit with slightly modified syntax).

Beyond OmniMark
Authors: Wilmott Sam
Published: July 2019

The field of programming languages is in continual flux: there are new languages coming along every few years. In the field of text and markup processing languages, things have settled down rather, with XSLT dominating and a few other languages like OmniMark filling in the gaps, but it is no more exempt from change than any other application area. Whether change is always improvement is not a certainty, but we must always be striving for improvement, so one hopes that there is such a thing that applies to our text and markup language field.

This paper starts with an overview of some existing text and markup processing languages, and concludes with an outline and examples of a new programming language, that I hope will make text and markup processing easier than is now the case, or at least provide thoughts as to which directions things can go.

DITA Grammar Customization
Authors: Kimber Eliot
Published: July 2019

The Darwin Information Typing Architecture (DITA) standard defines a layered extension mechanism, "specialization", for defining grammars such that the element types and attributes in any conforming DITA grammar are explicitly mapped back to one or more "base" types, with the lowest base type being the type defined in the core DITA grammar. This means that any conforming DITA document can be processed in terms of the base types of the document's elements and attributes, irrespective of how specialized the elements and attributes themselves are. The architecture itself depends only on the use of a DITA-defined attribute (@class), where the value is normally set as a default in the grammar. The DITA standard defines conventions for DTD and RELAX NG grammar modules that enable re-use of the declarations for base types when defining new types or constraining existing types and makes customizing content models about as easy as it can be. The DITA standard defines three types of customization: "configuration", "constraint", and "specialization". Configuration combines existing grammar modules in the context of a top-level "shell" grammar to define a unique DITA document type without directly defining or modifying any element type or attribute declarations. Constraints modify existing element type or attribute declarations to make them more constrained (such as disallowing specific elements) but does not add new element types or attributes. Specialization defines new element types or attributes. For DITA DTDs, customization is done through parameter entities and references to individual grammar modules. For DITA RNGs, customization is done through declaration or overriding of patterns. The DITA Technical Committee maintains tooling for generating conforming DITA DTDs from conforming DITA RNGs.
Customizing JATS (Journal Article Tag Suite)
Authors: Lapeyre Deborah A.
Published: July 2019

Document Type: The core JATS Document Type is a journal article and the ANSI/NISO JATS Tag Sets are journal article tag sets, which define XML elements and attributes to describe the content and/or the metadata of journal articles. Such articles may include: research articles; subject review articles; non-research articles; editorials; letters; product, software, and book reviews; obituaries, and the peer reviews or author responses included with an article.

Although originally just for journal articles, JATS-based tag sets have been built for: books (BITS: Book Interchange Tag Suite), standards (NISO STS, ISO STS), technical reports, conference proceedings, magazines and newsletters, and even posters.

Purpose: Provides common XML format to preserve the intellectual content of journal articles (independent of format of initial publication)

Expected Uses: Conversion target, archival storage, and interchange

Expected Users: Publishers, aggregators, vendors, web-hosts, libraries, and archives who produce, interchange, and store journal article content

When: ANSI/NISO Z39.96-2019 JATS: Journal Article Tag Suite (current)

Customization Mechanism: The JATS Journal Article Tag Sets are distributed in DTD form, XSD form, and RELAX NG form, but they are maintained as DTDs. The customization mechanism for DTDs is modularization and Parameter Entities, with customization-specific information overriding JATS-default information. This paper will describe, explain, and illustrate this mechanism. Specific customization samples are provided in the Appendix Sample JATS Customizations

M-BIM: a new tool for the Galleria dell’Accademia di Firenze
Authors: Tucci Grazia , Conti Alessandro , Fiorini Lidia , Corongiu Manuela , Valdambrini Noemi , Matta Carlotta
Published: July 2019

The paper deals with an ongoing research activity for developing a Building Information Model (BIM) for the facility and collections management of museums. The BIM success lies not only in its application for the design and construction of buildings but also because it helps the information management of a building throughout its life cycle. Compared to other activities, in museums management, the container/content relationship is essential for the preventive conservation of artworks, according to national and international guidelines. Then, an effective BIM-based museum information system linked to external databases (called M-BIM) should include also the art collections for managing information regarding both the building and artworks by 3D objects handling. This facilitates the management of the procedures prescribed by international best practices (as the facility and conservation reports set up for the loan of artworks) or by Italian regulations (as to check the compliance of a museum with the minimum standards or to archive renovations and temporary exhibitions). The proposed methodology has been tested on the Galleria dell’Accademia di Firenze (Florence, Italy), situated in a complex heritage building. Starting from data acquired during a laser scanner survey carried out in 2011, a HBIM of the whole building has been created. Then, the sculptures and paintings of a consistent part of the museum have been modelled with different approaches and inserted as BIM objects. Artworks instances include 3D geometry and physical data (dimensions, materials, weight, etc.), other data are obtained from links to already existing external catalogues. A database conceptual model has been formalised, according to INSPIRE Consolidated Unified Modelling Language (UML) of the INSPIRE Directive, with the aim to maintain the independence of the BIM approach but improving data connection with other databases and sources.

Highlights:

A holistic information management system for museums (M-BIM) is proposed, including both information on the building and the collections.

International and Italian guidelines, and best practices on museums management are compared.

The Galleria dell’Accademia di Firenze is used as a case study for testing the application of M-BIM on a heritage building.
Criação de áreas de risco: os problemas com alagamentos no distrito de Rio Vermelho, Florianópolis / SC
Authors: Luiz Edna Lindaura , Anjos Santos Larissa , Oliveira da Rosa João Paulo
Published: July 2019

O presente trabalho trata da criação de áreas de risco a alagamentos no Distrito de Rio Vermelho/SC. Este Distrito possui diferentes tipos de áreas úmidas, porém aquelas localizadas no interior do terraço marinho foram urbanizadas porque nem sempre estão úmidas ao longo do tempo. Moradores antigos sabiam que estas áreas alagavam em episódios de chuvas excepcionais, contudo, são pessoas migrantes que compraram terrenos ali. O parcelamento do solo irregular, sem planejamento e fiscalização do poder público associado ao desconhecimento da dinâmica natural do lugar criaram áreas de risco a alagamento. Medidas estruturais de drenagem não conseguirão acabar com os alagamentos por completo, por isso devem ser implantadas também medidas não-estruturais que diminuam a vulnerabilidade dos moradores.

Abstract. Methionine sulfoxide reductase B3 (MSRB3) is instrumental in ossification and fat deposition, which regulate the
growth and development of cattle directly. The purpose of this study was
aimed to explore insertions and deletions (indels) in MSRB3 gene and investigate
their association with growth traits in four indigenous cattle breeds (Luxi
cattle, Qinchuan cattle, Nanyang cattle, and Jiaxian Red cattle). Four indels
were identified by sequencing with DNA pool. Association analysis showed
that three of them were associated with growth traits (P<0.05). For
P1, the DD (deletion and deletion) genotype was significantly associated with body length of Nanyang
cattle; for P6, II (insertion and insertion) and/or DD genotypes were significantly associated with
enhanced growth traits of Qinchuan cattle; for P7, II genotype was
significantly associated with hucklebone width of Luxi cattle. Our results
demonstrated that the polymorphisms in bovine MSRB3 gene were significantly
associated with growth traits, which could be candidate loci for
marker-assisted selection (MAS) in cattle breeding.
Hygroscopic properties and CCN activity of atmospheric aerosols under the influences of Asian continental outflow and new particle formation at a coastal site in East Asia
Authors: Cheung Hing Cho , Chou Charles C.-K. , Lee Celine S. L. , Kuo Wei-Chen , Chang Shuenn-Chin
Published: July 2019

Abstract. The chemical composition of fine particulate matters (PM2.5), the size distribution and number concentration of aerosol particles (NCN) and the number concentration of cloud condensation nuclei (NCCN) were measured at the northern tip of Taiwan Island during a campaign from April 2017 to March 2018. The parameters of aerosol hygroscopicity (i.e. activation ratio, activation diameter and kappa) were retrieved from the measurements. Significant variations were found in the hygroscopicity of aerosols, which were suggested be subject to various pollution sources, including aged air pollutants originating in the eastern/northern China and transported on the Asian continental outflows, fresh particles emitted from local sources and distributed by land-sea breeze circulations as well as produced by new particle formation (NPF) processes. Cluster analysis was applied to the backward trajectories of air masses to investigate their respective source regions. The results showed that the aerosols associated with Asian continental outflows were characterized with higher kappa values, whereas higher NCCN and NCN with lower kappa values were found for aerosols in local air masses. The distinct features in hygroscopicity were consistent with the characteristics in the chemical composition of PM2.5. Moreover, this study revealed that the nucleation mode particles from NPF could have participated in the enhancement of CCN activity, most likely by coagulating with sub-CCN particles, although the freshly produced particles were not favored for CCN activation due to their smaller sizes. Thus, the results of this study suggested that the NPF coupling with coagulation processes can significantly increase the NCCN in atmosphere.

The composition and physicochemical properties of SOA differ a lot for they originated under different atmospheric conditions and from various precursors and oxidations. In this work, photooxidation experiments of toluene were performed under four conditions (dry, dry with SO2, wet, and wet with SO2) to investigate the effect of SO2 under different relative humidity on the composition and optical properties of SOA at the wavelength of 375 nm and 532 nm. According to our results, the increase of humidity enhances not only light absorption, but also scattering property of SOA. Highly conjugated oligomers formed through multiphase reaction might be the reasons of this phenomenon. Adding SO2 slightly lower the real part of complex refractive index (n) of SOA: ndry, SO2

Nuevas respuestas a la pobreza y exclusión social del Trabajo Social: la Mesa de Instituciones Sociales en Acción Social de Elda (Mesa ISAE)
Authors: Martínez-López José Ángel , Sánchez Carbonell María Ángeles
Published: July 2019

En última década nuestro país se ha visto inmerso en una grave crisis económica que ha puesto de relieve la dificultad del Estado de bienestar para dar una respuesta eficaz a las situaciones de pobreza y exclusión social. Desde el ámbito de los Servicios Sociales se han impulsado nuevas propuestas y estrategias de trabajo en red para cubrir las necesidades de la población que se encuentra en dificultad social. La Mesa ISAE se constituyó en el año 2009 para ofrecer una alternativa al trabajo que tanto desde el sistema público de Servicios Sociales como desde las entidades del tercer sector se venía desarrollando en el municipio de Elda (Alicante, Comunidad Valenciana). A través de esta actuación coordinada se han conseguido evitar duplicidades, establecer un procedimiento interinstitucional formal y mejorar la gestión. Los resultados de nuestra investigación confirman la potencialidad de este instrumento para dar una respuesta inmediata a la ciudadanía, reduciendo la burocracia y mejorando el bienestar de la ciudadanía.
Reflexiones de una trabajadora social académica

Me he tomado este acto de presentación del libro, Epistemología del Trabajo Social. De la evidencia empírica a la exigencia teórica, como si fuera una clase, tal vez porque este curso no he dado ninguna en la Facultad, y siento “mono” del encuentro que me proporciona este escenario. Sí, lo tengo, queridas alumnas, colegas docentes y profesionales, queridas todas. Muchas gracias por hacerme revivir de vez en cuando la pasión que me sostuvo tanto tiempo.
Evaluación de atención, memoria y flexibilidad cognitiva en niños bilingües
Authors: Castro Castiblanco Yira Marieta , Zuluaga Valencia Juan Bernardo
Published: July 2019

El artículo pretende identificar el impacto de la exposición temprana a una segunda lengua sobre algunas de las funciones ejecutivas, en relación con el tiempo de exposición y sexo de los participantes. El diseño metodológico es de tipo descriptivo, con alcance correlacional cuasi experimental, tipo caso control. La muestra es no probabilística, conformada por 30 niños en edades entre 5 y 6 años, en contexto escolarizado urbano. Para establecer el perfil cognitivo de los participantes se tomaron en cuenta como instrumentos la evaluación neuropsicológica infantil (ENI) y la escala WISC III abreviada (cubos y vocabulario). Se evidenció desempeño de los niños bilingües en memoria auditiva verbal; en atención visual y memoria de trabajo, los resultados son relativamente altos. En flexibilidad cognitiva, no se evidencian diferencias significativas para ambos grupos (bilingües y no bilingües). Encontramos diferencias entre niños y niñas: en memoria verbal auditiva y atención visual, las niñas muestran mejores desempeños, mientras que los niños obtuvieron mejores desempeños en las pruebas de memoria de trabajo. Por último, no encontramos correlación estadísticamente significativa entre coeficiente intelectual y resultados de la ENI.
Inclusión educativa en relación con la cultura y la convivencia escolar
Authors: Valdés Morales René Alonzo , López Leiva Verónica Alejandra , Jiménez Vargas Felipe Andrés
Published: July 2019

El objetivo de este estudio es caracterizar la convivencia y la cultura escolar desde la perspectiva de la inclusión. El diseño del estudio es mixto: evaluación cuantitativa de las dimensiones convivencia escolar inclusiva y cultura inclusiva, en 129 escuelas chilenas (N = 2.868 estudiantes, 1.129 padres y 741 docentes y profesionales de la educación). Luego, seleccionamos dos casos extremos y realizamos una aproximación etnográfica. Los resultados indican que la escuela con baja convivencia escolar y baja cultura inclusiva mantenía relaciones interpersonales fragmentadas, con desorganización de roles y funciones y con un foco de interés prioritario puesto en la mejora de la convivencia. En contraste, la escuela con alta convivencia escolar y alta cultura inclusiva presentaba relaciones humanas cohesionadas, claridad de roles y funciones y su actual foco era de carácter pedagógico.

The Northwest quartz-pyrite-gold veins are situated 500 m east of the Lepanto fault in Mankayan, Luzon, Philippines. Most vein mineralization is hosted by the Lepanto metavolcanic basement rocks at an elevation between 700 and 1,050 m. The earliest stage, stage 1, is characterized by sphalerite + chalcopyrite + pyrite ± magnetite veins cutting the host rocks that were altered to chlorite + illite + epidote. Precious metal deposition started in stage 2 as electrum, native gold, and gold-silver tellurides deposited with pyrite, quartz, and carbonate. Deposition of gold and silver tellurides continued in stage 3a with abundant pyrite and tennantite-tetrahedrite solid solution intergrown with chalcopyrite, bornite, and minor sphalerite. The stage 3a veins and host-rock alteration are characterized by abundant muscovite and quartz, while the stage 3b veins and alteration consist of quartz, pyrophyllite, alunite, and dickite. Enargite and luzonite are the dominant sulfide minerals in stage 4, which are either disseminated in silicified host rock or within wide quartz veins. Lesser amounts of quartz and abundant pyrite with inclusions of enargite and luzonite were precipitated in stage 5.

Microthermometry on fluid inclusions in quartz of stages 2, 3a, and 4 indicates boiling of the hydrothermal fluids. Bulk gas analysis on fluid inclusions in quartz shows that the stage 2 and 4 fluids had components derived from basaltic and andesitic magma, respectively. Fluids that formed stage 4 quartz were more diluted by meteoric water than the fluids that formed the stage 2 veins. Radiometric 40Ar/39Ar dating on alunite separated from the stage 3b advanced argillic alteration zone yielded 2.2 ± 0.1 Ma. Sulfur isotope compositions of the Northwest quartz-pyrite-gold deposit reveal a bulk δ34S of approximately 5‰, similar to the calculated value for the adjacent Far Southeast porphyry deposit. Calculated oxygen and hydrogen isotope ratios of the fluids of the Northwest quartz-pyrite-gold deposit stage 3b dickites are similar to those that formed the illite alteration in the Far Southeast porphyry deposit but are higher in δ18O when compared to the fluids that formed the kandites in the Lepanto enargite deposit. The northward cooling of mineralizing fluids previously reported in the Lepanto enargite deposit is not consistent with the mineralogic indications in the Northwest quartz-pyrite-gold deposit. These data indicate multiple mineralization events in the Mankayan district, which is one of the largest mineral districts in the western Pacific.
Taxation and Income Inequality in Nigeria
Authors: Anyaduba John Obiora , Otulugbu Praise Oghenefejiro
Published: July 2019

The study examined taxation and income inequality (GINI), specifically, it determined the impact of Value Added Tax (VAT), Custom and Excise Duties (CED), Petroleum Profit Tax (PPT) and Company Income Tax (CIT) on GINI in Nigeria from the year 1990 to 2016. The Cointegration and Error Correction Models (ECMs) were used to analyze the data. Augmented Dickey Fuller unit root was used to test for stationarity. Data were sourced from the Central Bank of Nigerian statistical bulletin, Federal Inland Revenue Service and the National Bureau of Statistics. The result revealed that VAT, CED and PPT had positive relationship with GINI when measured at 5% critical level, though VAT and CED were not significant. CIT had a negative but significant impact on GINI. Based on the findings, we conclude that only CIT was able to reduce income inequality. We therefore recommend that VAT should be imposed on goods and services consumed by high income earners. In respect of CED, government should address the level of tariffs; for PPT, there is need for adequate diversification of the economy; and for CIT, tax authority should harness corporate taxes to its fullness.

Agricultural irrigation is involved in an important chain that involves all sectors of the economy, either directly, by increasing food production, or indirectly, by withdrawing large amounts of fresh water. The relevance of this theme forces the search for alternatives to make water use as rational as possible. Evapotranspiration estimation methods based in remote sensing, such as the SAFER (Simple Algorithm for Evapotranspiration Retrieving) model, become extremely relevant in these scenarios, since it is possible to estimate this parameter in large scales. Therefore, the aim of this research was to apply the SAFER model in the estimation of bean crop actual evapotranspiration using Landsat-8 satellite image data. One of the parameters used as input in the SAFER model is the NDVI (Normalized Difference Vegetation Index), which presented a coefficient of determination (r²) equal to 0.80 when compared to the crop coefficient. The actual evapotranspiration (ETa) estimated by the SAFER model were compared to the FAO 56 model estimates for later correlation between the models. This information is expected to assist the producer in a better management of water resources used in irrigation. The correlation between the two models presented a relevant coefficient of determination (r2 = 0.73), representing the potential of the SAFER model in relation to the FAO model 56.
