The Toledo Mountains: A Resilient Landscape and a Landscape for Resilience? Hazards and Strategies in a Mid-Elevation Mountain Region in Central Spain
Authors: Luelmo-Lautenschlaeger Reyes , Pérez-Díaz Sebastián , Blarquez Olivier , Morales-Molino César , López-Sáez José Antonio
Published: October 2019

The Toledo Mountains are a mid-elevation mountain range that separates the Tagus and Guadiana basins in the central area of the Iberian Peninsula. The location of these mountains allows the development of typical Mediterranean vegetation with some Atlantic influence. Consequently, typical broadleaved evergreen Mediterranean vegetation currently dominates the regional landscape, with the remarkable presence of more mesophilous species in sheltered and more humid microsites such as gorges (e.g., Prunus lusitanica, Taxus baccata, Ilex aquifolium) and mires/bogs (e.g., Betula pendula susbp. fontqueri, Erica tetralix, Myrica gale). Palaeoecological studies in these mountains are essential to understand the long-term ecology and original distribution of these valuable communities and are key to assess their resilience. Understanding the hazards and opportunities faced in the past by the plant communities of the Toledo Mountains is necessary to enhance the management and protection of those species currently threatened. This study focuses on El Perro mire, a peatland on the southern Toledo Mountains (central Spain) where climatic variability has played a major role in landscape dynamics at multi-decadal to millennial timescales. Climatic events such as the 4.2 ka cal. Before Present (BP) or the Little Ice Age triggered relevant landscape changes such as the spread and latter decline of birch and hazel forests. Human communities also seemed to be affected by these events, as their resilience was apparently jeopardized by the new climatic conditions and they were forced to find new strategies to cope with the new scenarios.
A Process Theology of Hope: The Counter Apocalyptic Vision of Catherine Keller
Authors: Macallan Brian
Published: October 2019

Christianity continues to decline in the traditional west, yet is at the same time experiencing significant growth in the majority world. Research indicates that by 2060 the portion of those who identify as non-religious will decline significantly across the globe. Christianity in the future will largely be dominated by an apocalyptic eschatology that has the potential to disengage Christians from our current planetary crisis. Catherine Keller has developed a counter-apocalyptic vision that challenges traditional eschatology in its potential to disconnect faith from the planet’s most urgent challenges. Keller attacks a key facet of apocalyptic eschatology that enshrines an omnipotent deity. Her approach is evaluated within the broader process-relational theology from which she has emerged, particularly that influenced by Whitehead. It is argued that her eschatological alternative is best placed to offer a vision that enables Christians to take the earth seriously, to generate a chastened and realistic hope, grounded in a process relational ontology.
Numerical Optimization of a Fully Cross-Coupled Rectifier Circuit for Wireless Passive Ultra Low Power Sensor Nodes
Authors: Mair Dominik , Ferdik Manuel , Happ Christof , Renzler Michael , Ussmueller Thomas
Published: October 2019

In the context of the Internet of Things, billions of devices—especially sensors—will be linked together in the next few years. A core component of wireless passive sensor nodes is the rectifier, which has to provide the circuit with sufficient operating voltage. In these devices, the rectifier has to be as energy efficient as possible in order to guarantee an optimal operation. Therefore, a numerical optimization scheme is proposed in this paper, which is able to find a unique optimal solution for an integrated Complementary Metal-Oxide-Semiconductor (CMOS) rectifier circuit with Self-Vth-Cancellation (SVC). An exploration of the parameter space is carried out in order to generate a meaningful target function for enhancing the rectified power for a fixed communication distance. In this paper, a mean conversion efficiency is introduced, which is a more valid target function for optimization than the Voltage Conversion Efficiency (VCE) and the commonly used Power Conversion Efficiency (PCE) and is defined as the arithmetic mean between PCE and VCE. Various trade-offs between output voltage, PCE, VCE and MCE are shown, which provide valuable information for low power rectifier designs. With the proposed method, a rectifier in a low power 55 nm process from Globalfoundries (GF55LPe) is optimized and simulated at −30 dBm input power. A mean PCE of 63.33% and a mean VCE of 63.40% is achieved.

Published: October 2019

Nanomechanical characterization of vertically aligned micro- and nanopillars plays an important role in quality control of pillar-based sensors and devices. A microelectromechanical system based scanning probe microscope (MEMS-SPM) has been developed for quantitative measurement of the bending stiffness of micro- and nanopillars with high aspect ratios. The MEMS-SPM exhibits large in-plane displacement with subnanometric resolution and medium probing force beyond 100 micro-Newtons. A proof-of-principle experimental setup using an MEMS-SPM prototype has been built to experimentally determine the in-plane bending stiffness of silicon nanopillars with an aspect ratio higher than 10. Comparison between the experimental results and the analytical and FEM evaluation has been demonstrated. Measurement uncertainty analysis indicates that this nano-bending system is able to determine the pillar bending stiffness with an uncertainty better than 5%, provided that the pillars’ stiffness is close to the suspending stiffness of the MEMS-SPM. The MEMS-SPM measurement setup is capable of on-chip quantitative nanomechanical characterization of pillar-like nano-objects fabricated out of different materials.

Published: October 2019

Individuals who sustained a spinal cord injury often lose important motor skills, and cannot perform basic daily living activities. Several assistive technologies, including robotic assistance and functional electrical stimulation, have been developed to restore lost functions. However, designing reliable interfaces to control assistive devices for individuals with C4–C8 complete tetraplegia remains challenging. Although with limited grasping ability, they can often control upper arm movements via residual muscle contraction. In this article, we explore the feasibility of drawing upon these residual functions to pilot two devices, a robotic hand and an electrical stimulator. We studied two modalities, supra-lesional electromyography (EMG), and upper arm inertial sensors (IMU). We interpreted the muscle activity or arm movements of subjects with tetraplegia attempting to control the opening/closing of a robotic hand, and the extension/flexion of their own contralateral hand muscles activated by electrical stimulation. Two groups were recruited: eight subjects issued EMG-based commands; nine other subjects issued IMU-based commands. For each participant, we selected at least two muscles or gestures detectable by our algorithms. Despite little training, all participants could control the robot’s gestures or electrical stimulation of their own arm via muscle contraction or limb motion.

Published: October 2019

Surface acoustic wave sensors have the advantage of fast response, low-cost, and wireless interfacing capability and they have been used in the medical analysis, material characterization, and other application fields that immerse the device under a liquid environment. The theoretical analysis of the single guided layer shear horizontal acoustic wave based on the perturbation theory has seen developments that span the past 20 years. However, multiple guided layer systems under a liquid environment have not been thoroughly analyzed by existing theoretical models. A dispersion equation previously derived from a system of three rigidly coupled elastic mass layers is extended and developed in this study with multiple guided layers to analyze how the liquid layer’s properties affect the device’s sensitivity. The combination of the multiple layers to optimize the sensitivity of an acoustic wave sensor is investigated in this study. The Maxwell model of viscoelasticity is applied to represent the liquid layer. A thorough analysis of the complex velocity due to the variations of the liquid layer’s properties and thickness is derived and discussed to optimize multilayer Surface acoustic wave (SAW) sensor design. Numerical simulation of the sensitivity with a liquid layer on top of two guided layers is investigated in this study as well. The parametric investigation was conducted by varying the thicknesses for the liquid layer and the guided layers. The effect of the liquid layer viscosity on the sensitivity of the design is also presented in this study. The two guided layer device can achieve higher sensitivity than the single guided layer counterpart in a liquid environment by optimizing the second guided layer thickness. This perturbation analysis is valuable for Love wave sensor optimization to detect the liquid biological samples and analytes.

Published: October 2019

Overcoming the diffraction limit, which enables focusing much less than the wavelength, requires tailoring the evanescent spectrum of an aperture’s field distribution. We model and simulate a corrugated near field plate, which can generate a sub-wavelength focus in inhomogeneous background media. All reactive coupling, between the metasurface near field plate and the focusing domain and among the corrugations in the metasurface, is taken into consideration with the finite element method, which we solve in combination with a constraint to generate a desired focus. Various geometries for the near field plate are considered and we demonstrate that the proposed method can effectively create a deeply sub-wavelength focus within a layered medium having properties resembling brain tissue. Such a device could find use as a detector of biological signals or for hyperthermic treatment near the skin surface.
Robust Estimators in Geodetic Networks Based on a New Metaheuristic: Independent Vortices Search

Published: October 2019

Geodetic networks provide accurate three-dimensional control points for mapping activities, geoinformation, and infrastructure works. Accurate computation and adjustment are necessary, as all data collection is vulnerable to outliers. Applying a Least Squares (LS) process can lead to inaccuracy over many points in such conditions. Robust Estimator (RE) methods are less sensitive to outliers and provide an alternative to conventional LS. To solve the RE functions, we propose a new metaheuristic (MH), based on the Vortex Search (IVS) algorithm, along with a novel search space definition scheme. Numerous scenarios for a Global Navigation Satellite Systems (GNSS)-based network are generated to compare and analyze the behavior of several known REs. A classic iterative RE and an LS process are also tested for comparison. We analyze the median and trim position of several estimators, in order to verify their impact on the estimates. The tests show that IVS performs better than the original algorithm; therefore, we adopted it in all subsequent RE computations. Regarding network adjustments, outcomes in the parameter estimation show that REs achieve better results in large-scale outliers’ scenarios. For detection, both LS and REs identify most outliers in schemes with large outliers.
A Novel Sensor Data Pre-Processing Methodology for the Internet of Things Using Anomaly Detection and Transfer-By-Subspace-Similarity Transformation
Authors: Zhong Yan , Fong Simon , Hu Shimin , Wong Raymond , Lin Weiwei
Published: October 2019

The Internet of Things (IoT) and sensors are becoming increasingly popular, especially in monitoring large and ambient environments. Applications that embrace IoT and sensors often require mining the data feeds that are collected at frequent intervals for intelligence. Despite the fact that such sensor data are massive, most of the data contents are identical and repetitive; for example, human traffic in a park at night. Most of the traditional classification algorithms were originally formulated decades ago, and they were not designed to handle such sensor data effectively. Hence, the performance of the learned model is often poor because of the small granularity in classification and the sporadic patterns in the data. To improve the quality of data mining from the IoT data, a new pre-processing methodology based on subspace similarity detection is proposed. Our method can be well integrated with traditional data mining algorithms and anomaly detection methods. The pre-processing method is flexible for handling similar kinds of sensor data that are sporadic in nature that exist in many ambient sensing applications. The proposed methodology is evaluated by extensive experiment with a collection of classical data mining models. An improvement over the precision rate is shown by using the proposed method.
A New Approach for Motor Imagery Classification Based on Sorted Blind Source Separation, Continuous Wavelet Transform, and Convolutional Neural Network

Published: October 2019

Brain-Computer Interfaces (BCI) are systems that allow the interaction of people and devices on the grounds of brain activity. The noninvasive and most viable way to obtain such information is by using electroencephalography (EEG). However, these signals have a low signal-to-noise ratio, as well as a low spatial resolution. This work proposes a new method built from the combination of a Blind Source Separation (BSS) to obtain estimated independent components, a 2D representation of these component signals using the Continuous Wavelet Transform (CWT), and a classification stage using a Convolutional Neural Network (CNN) approach. A criterion based on the spectral correlation with a Movement Related Independent Component (MRIC) is used to sort the estimated sources by BSS, thus reducing the spatial variance. The experimental results of 94.66% using a k-fold cross validation are competitive with techniques recently reported in the state-of-the-art.

Published: October 2019

The health state of rotating machinery directly affects the overall performance of the mechanical system. The monitoring of the operation condition is very important to reduce the downtime and improve the production efficiency. This paper presents a novel rotating machinery fault diagnosis method based on the improved multiscale amplitude-aware permutation entropy (IMAAPE) and the multiclass relevance vector machine (mRVM) to provide the necessary information for maintenance decisions. Once the fault occurs, the vibration amplitude and frequency of rotating machinery obviously changes and therefore, the vibration signal contains a considerable amount of fault information. In order to effectively extract the fault features from the vibration signals, the intrinsic time-scale decomposition (ITD) was used to highlight the fault characteristics of the vibration signal by extracting the optimum proper rotation (PR) component. Subsequently, the IMAAPE was utilized to realize the fault feature extraction from the PR component. In the IMAAPE algorithm, the coarse-graining procedures in the multi-scale analysis were improved and the stability of fault feature extraction was promoted. The coarse-grained time series of vibration signals at different time scales were firstly obtained, and the sensitivity of the amplitude-aware permutation entropy (AAPE) to signal amplitude and frequency was adopted to realize the fault feature extraction of coarse-grained time series. The multi-classifier based on the mRVM was established by the fault feature set to identify the fault type and analyze the fault severity of rotating machinery. In order to demonstrate the effectiveness and feasibility of the proposed method, the experimental datasets of the rolling bearing and gearbox were used to verify the proposed fault diagnosis method respectively. The experimental results show that the proposed method can be applied to the fault type identification and the fault severity analysis of rotating machinery with high accuracy.
Public Attitudes toward Sustainable Development Goals: Evidence from Five Chinese Cities
Authors: Guan Ting , Meng Ke , Liu Wei , Xue Lan
Published: October 2019

Raising public awareness of the Sustainable Development Goals (SDGs) is a critical prerequisite for their implementation. However, little is known about attitude formation among the public toward SDGs at the national level. We explored this topic in China, a country that has emerged as a leading world economy with strong transformational imperatives to work toward sustainable development. Following Chaiken’s heuristic–systematic model and using data from an online survey with 4128 valid respondents, this study investigated the factors that affect public support for SDGs and explains how individuals form supportive attitudes. Our empirical evidence showed that in China, first, public support is mainly shaped by demographic attributes (gender, age, and educational attainment), value predispositions (e.g., altruistic values and anthropocentric worldviews), and the level of SDG-relevant knowledge. Second, an interaction effect exists between value predispositions and knowledge among the public concerning support for SDGs. Third, the Chinese public views the implementation of SDGs as a part of development policy rather than environmental policy. This study provides empirical findings on the factors that account for public attitudes toward SDGs, outlining some useful implications for designing policy tools that would bolster SDG action.

Authors: Liu He-Hai , Wang Qi , Su Yu-Sheng , Zhou Liang
Published: October 2019

In the context of the Internet for education, informatized teaching has become the most basic and critical ability of teachers. The application of advanced information technology in education means that the improvement in teaching ability requires instructors to better utilize teaching and learning opportunities. Project-based learning is an inquiry-based learning method that embodies learning by doing. With respect to the training of informatization teaching for pre-service teachers, we choose three aspects: information-based instructional design, information-based teaching resource integration, and information-based teaching evaluation, respectively, from PowerPoint (PPT) skills, multimedia courseware production, and micro lectures. This study explores three experimental projects and undertakes detailed empirical growth research on the cultivation of pre-service teachers. We were able to enhance the informatization teaching design ability of pre-service teachers with the training of PPT skills. In this experiment, we found that integration of information-based teaching resources can be improved by the integration of multimedia courseware production. Information teaching evaluation can be improved through micro lecture production. The mechanism provides a more feasible and practical strategy for the training of pre-service teachers in their informatization teaching ability.
An Environmental Health Typology as a Contributor to Sustainable Regional Urban Planning: The Case of the Metropolitan Region of São Paulo (MRSP)
Authors: Maria Natasha , Medeiros-Sousa Antônio , Slovic Anne
Published: October 2019

The recognition of metropolitan regions and their growth as a necessary scale of analysis for their integrated management has become a central characteristic of urban planning. The current metropolitan landscape warrants the use of instruments beyond the municipal scale, especially since the economic integration of cities and their development are accentuating urban problems that affect the sustainability of cities. The São Paulo Metropolitan Region (MRSP), one of the world’s megacities, is used as a case study to identify how typologies can contribute to integrated sustainable urban planning and management at the metropolitan level. It applies the territorial analytical typology based on the Driving-Force-Pressure-Situation-Exposure-Effect-Actions (DPSEEA) Environmental Health Matrix to identify the heterogeneity of conditions encountered in large metropolitan regions such as the MRSP. The results show a great variety of environmental and social conditions present in the municipalities of the MRSP that condition the sustainability and health of the urban environment. This typology constitutes a first step to characterize metropolitan regions in socioenvironmental terms using as a conceptual basis a matrix of environmental health indicators, being a precursor in the largest metropolitan region of Brazil.
Equality in Income and Sustainability in Economic Growth: Agent-Based Simulations on OECD Data
Authors: Sakaki Shungo
Published: October 2019

In countries that have developed under the current market economy, inequalities in income distribution tend to increase with three different trends, i.e., high (United States, United Kingdom, Japan), low (North Europe countries), and medium Gini coefficient levels. On the other hand, the relationship between income distribution and social welfare is generally a difficult problem to solve in economics. So, this paper discusses the impact of income distribution on the macroeconomy, limiting the scope to consistency with long-term economic growth. We attempt to answer these economic policy issues by simulation using an agent-based model based on replicator dynamics. As a result of the simulation in this paper, in general, in countries with the high marginal propensity to consume, long-term growth can be maintained by inducing equality in income distribution. On the other hand, a mature country with a low marginal propensity to consume can sustain not so high but stable growth despite increasing inequality in income distribution. According to simulation results based on OECD (Organisation for Economic Co-operation and Development) data, in the former UK, US, and Japan, the lower the Gini coefficient is, the higher the growth potential is, while in the latter Norway and Luxembourg, relatively stable growth is maintained even if the Gini coefficient increases.

Viruses are the major causes of acute and chronic infectious diseases in the world. According to the World Health Organization, there is an urgent need for better control of viral diseases. Repurposing existing antiviral agents from one viral disease to another could play a pivotal role in this process. Here, we identified novel activities of obatoclax and emetine against herpes simplex virus type 2 (HSV-2), echovirus 1 (EV1), human metapneumovirus (HMPV) and Rift Valley fever virus (RVFV) in cell cultures. Moreover, we demonstrated novel activities of emetine against influenza A virus (FLUAV), niclosamide against HSV-2, brequinar against human immunodeficiency virus 1 (HIV-1), and homoharringtonine against EV1. Our findings may expand the spectrum of indications of these safe-in-man agents and reinforce the arsenal of available antiviral therapeutics pending the results of further in vitro and in vivo tests.

Vaccine hesitancy is a continuum of behaviors ranging from delay in receipt to vaccination refusal. Prior studies have typically focused on high-income countries, where vaccine hesitancy is particularly prevalent in more affluent groups, but the relationship between socioeconomic status and vaccine hesitancy in Low- and Middle-Income Countries (LMICs) is less clear. The aim of this study was to describe vaccine hesitancy in five LMICs. Mothers of children in Sirajganj, Bangladesh (n = 60), Shanghai, China (n = 788), Addis Ababa, Ethiopia (n = 341), Guatemala City and Quetzaltenango, Guatemala (n = 767), and Chandigarh, India (n = 309), completed a survey between 2016 and 2018 using the WHO’s 10-item Vaccine Hesitancy Scale. The scores of different constructs were compared across countries and by the mother’s education level using linear regression models with generalized estimating equations. Compared to mothers in China, mothers in Bangladesh perceived less vaccination benefit (β: 0.56, P = 0.0001), however, mothers in Ethiopia (β: −0.54, P < 0.0001) and Guatemala (β: −0.74, P = 0.0004) perceived greater benefit. Education level was not significantly linked with vaccine hesitancy. Local circumstances are important to consider when developing programs to promote vaccines. We did not find consistent associations between education and vaccine hesitancy. More research is needed to understand socio-cultural influences on vaccine decision-making.

Enzyme linked immunosorbent assays (ELISAs) have been developed for the detection of antibodies against contagious caprine pleuropneumonia (CCPP), the causative agent of which is Mycoplasma capricolum subsp. Capripneumoniae (Mccp). The currently available commercial CCPP competitive ELISA (CCPP cELISA) kit produced and supplied by IDEXX Company (Westbrook, Maine, United States) is relatively expensive for most African laboratories. To address this issue and provide a variety of choices, a sensitive and specific blocking-ELISA (b-ELISA) test to detect antibodies against CCPP was developed. We describe the newly developed CCPP blocking-ELISA based on the blocking of an epitope of a monoclonal antibody (Mccp-25) by a positive serum sample against the Mccp protein coated on a plate. The Percentage Inhibition (PI) cut-off value for the CCPP b-ELISA was set at 50 using 466 CCPP negative and 84 CCPP positive small ruminant sera. Of the negative sera, 307 were obtained from the Botswana National Veterinary Laboratory (BNVL) and 159 from the Friedrich-Loeffler-Institute (FLI) Germany. The 84 positive sera samples came from experimentally vaccinated goats at the AU-PANVAC facility in Debre-Zeit, Ethiopia. The relative diagnostic sensitivity and specificity of the CCPP b-ELISA was 93% and 88%, respectively. This test result indicated good correlation with that of the commercial CCPP cELISA by IDEXX Company (Westbrook, Maine, United States) with a Cohen’s κ agreement of κ agreement of 0.85. The newly developed CCPP b-ELISA will be useful in the detection of antibodies for the diagnosis CCPP and for sero-surveillance during vaccination campaigns.
Decision-Making Challenges of Sustainable Groundwater Strategy under Multi-Event Pressure in Arid Environments: The Diyala River Basin in Iraq
Authors: Al-Jawad Jafar Y. , Al-Jawad Sadik B. , Kalin Robert M.
Published: October 2019

A robust decision-making tool is needed to meet sustainability challenges and to manage water resources that are under development pressure, water scarcity, and climate change impact. To tackle such challenges, optimization modelling can be employed to explore regional sustainable management scenarios of groundwater exploitation. Multi-objective management modelling of various alternatives was developed for the Diyala River Basin in Iraq using Borg multi-objectives evolutionary algorithm (MOEA) and ε-DSEA algorithms. In almost all modelled cases, the upper aquifer storage is predicted to be depleted after 40 years due to large water demands and regional recharge scarcity. Hence, there is a need to develop a strategy to reduce water stresses by 45% to achieve sustainability within the next 25 years. Optimization modelling successfully generated future predictions that can be used by decision makers to manage the predicted groundwater shortages in the future.
Análise de representações de fluxos migratórios contemporâneos na narrativa jornalística brasileira sob a perspectiva do conceito de pânico moral
Authors: Frazão Samira Moratti , Assis Gláucia De Oliveira
Published: October 2019

A partir da análise de um caso de suspeita de ebola no Brasil em 2014, envolvendo um refugiado de origem africana, a proposta do artigo, recorte de tese em andamento, foi problematizar como o refugiado foi representado na cobertura (tele)jornalística e como se deu a construção dessa realidade. Acredita-se que a abordagem jornalística pode ter contribuído para a disseminação de um pânico moral na sociedade brasileira, desencadeando manifestações racistas e xenofóbicas nos canais pelos quais o público emite opinião em sites jornalísticos. Foram analisadas duas reportagens de um total de 68 publicadas em outubro de 2014 em sites jornalísticos brasileiros, por meio do método Análise de Conteúdo. As reportagens expuseram o refugiado como "ameaça", marginalizando-o e impactando negativamente na inserção e integração de outros imigrantes e refugiados contemporâneos.
A representação do migrante colombiano na imprensa colombiana: do espaço individual ao espaço colectivo
Authors: Botero Victoria Elena Bazurto
Published: October 2019

O objetivo deste artigo é identificar as representações dos migrantes colombianos na Espanha, através do discurso dos jornais El Tiempo e El Espectador. Com esse propósito, analisaram-se os artigos dos dois periódicos a partir do 01 de janeiro de 1990 até 31 de dezembro de 2006. Abordaremos a análise desde a perspectiva de Habermas sobre o espaço público e o espaço privado. Os resultados demonstram que a representação dos espaços se constrói a partir de um discurso não remetente à ideia nem de confronto nem de crença, mas, de modo contrário, reorganiza-se desde o espaço público ao universo masculino, problemático no país de destino, e desde o espaço privado ao universo feminino, que é conflitivo no país de origem.

No caminho das amazonas: notas sobre migração e perambulação de personagens femininos em Iracema, uma transa amazônica e Bye bye Brasil
Authors: Carvalho Marcelo
Published: October 2019

O objetivo deste trabalho é pensar os deslocamentos espaciais e os processos de subjetivação de alguns personagens femininos em dois filmes brasileiros – Iracema, uma transa amazônica (1975), de Jorge Bodanzky e Orlando Senna, e Bye bye Brasil (1980), de Carlos Diegues –, tendo em vista serem ambos paradigmáticos quanto ao tema da migração no âmbito da rodovia Transamazônica. Concluímos que Iracema, Salomé e Dasdô, personagens desses filmes, adotam formas variadas de perambulação (extensiva e intensiva) dentro dos contextos migratórios nos quais se inserem. Como suporte teórico, baseamo-nos principalmente no conceito de nomadismo, de Gilles Deleuze e Félix Guattari, e de não lugar, de Marc Augé.

Published: October 2019

Delimitada na legislatura 2013-2016, busca-se pelas ações de vereadores evangélicos que incluem valores religiosos e podem influenciar no cotidiano de cidades da Região Metropolitana de Curitiba. Legalizadas, a efetividade das leis pode atestar a comunhão de um mesmo ideário entre os vereadores e a população, mas diametralmente oposta, também expor o distanciamento em relação aos anseios da maioria. Tão recente quanto notório, o interesse dos evangélicos em participar das decisões políticas do país instiga pesquisas acerca das defesas dos valores morais que legitimam. Postulados de Morin, Burke, Certeau e Ultramari sustentam o pressuposto da tríade formada por vereadores, população e valores evangélicos e, conforme combina conhecimento e informação, faz circular ideias que decorrem de ações contundentes, independentes ou ornamentais.

O “Pós-Digital” é um termo que ultrapassa fronteiras do campo cada vez mais expandido da Cultura Digital. Envolve o contexto das artes, da cultura, da cognição e sobretudo do poder. No cenário internacional a utilização do termo é corrente, o que implica na necessidade de uma pausa para que se possa compreender sua dimensão.
A utilização do prefixo pós- não implica dizer que o que veio antes acabou, mesmo porque o mundo atual apresenta elementos que são absolutamente pré-digitais, digitais e também pós-digitais, mas é uma crítica e uma ampliação ao conceito do termo precedente. E isso acontece porque a sociedade não pode ser vista de forma linear, estanque; determinadas forças do passado modificam a paisagem do presente, possibilitando uma nova imersão no futuro. Por meio de reflexões sobre essas novas possibilidades de conceituação, implicação e utilização do termo, Lucia Santaella proporcionou uma comunhão de suas diversas obras, trazendo novos pensamentos em relação ao contexto contemporâneo que acaba com a Era das Massas e traz um coletivo individualizado. A seguir, apresentamos trechos de uma entrevista com a autora que contribuem para o entendimento do conceito e abrangência do termo.
Lucia Santaella é pesquisadora 1A do CNPQ, professora titular na pós-graduação em Comunicação e Semiótica e na Pós-Graduação em Tecnologias da Inteligência e Design Digital (PUC-SP). Doutora em Teoria Literária pela PUC-SP e livre-docente em Ciências da Comunicação pela USP. Publicou 41 livros e organizou 14, além da publicação de mais de 300 artigos no Brasil e no exterior.

Çalışmanın amacı bir üniversitenin
iki ayrı fakültesinde okuyan üniversite öğrencilerindeki flört şiddeti
prevalanslarının saptanması ve etkileyen etmenlerin karşılaştırılmasıdır.
Kesitsel tipte olan bu çalışma, araştırmacılar tarafından oluşturulan anketler
aracılığıyla, 1 Mayıs- 30 Haziran 2017 tarihleri arasında
gerçekleştirilmiştir.  Basit rastgele
örnekleme yöntemiyle 435 öğrenci seçilmiştir. Frekans analizleri, ki-kare ve
lojistik regresyon analizleri uygulanmıştır. Toplam 424 öğrenci araştırmaya
katılmış ve bunların %21.4’ünde flört şiddeti maruziyeti saptanmıştır. Cinsiyet
ve fakülte ile flört şiddeti arasında anlamlı bir ilişki saptanmazken;
çocuklukta aile içi şiddete maruz kalanlarda 2.7 kat (%95GA=1.4-5.5; p=0.003)
daha fazla maruziyet görülmüştür.  Flört
şiddetini engellemek için aile içi şiddeti önlemeye yönelik etkin politikalar
uygulanmalı ve üniversite öğrencilerine yönelik danışmanlık ve eğitim
hizmetleri verilmelidir.
Las ciencias en el aula y el interés por las carreras científico-tecnológicas
Authors: Polino Carmelo
Published: October 2019

Las estadísticas educativas muestran que el problema de las vocaciones científicas es particularmente agudo en el caso de las áreas de las ciencias exactas y naturales y en ciertas ramas de las ingenierías. La preocupación ha llevado a que se plantee como urgente conocer las causas estructurales y subjetivas que influyen en esta tendencia. En el artículo que nos ocupa se difunden indicadores seleccionados de una encuesta aplicada a estudiantes de secundaria de varias ciudades de Iberoamérica. Se analiza el interés por las carreras científicas de las áreas de las ciencias exactas y naturales y, específicamente, por las profesiones científicas y las ingenierías como posibles opciones laborales. Además, se exploran los factores que condicionan el interés de los adolescentes para optar por las ciencias. De igual forma se repasan actitudes frente a las clases de ciencias y, por último, se incorpora un análisis de las actitudes frente a riesgos y beneficios de la ciencia y la tecnología y su introducción como tópicos en las aulas. En cada caso los indicadores presentados se contrastan con variables sociales y educativas de interés. Finalmente, en la discusión se plantea la necesidad de afrontar de forma coordinada los problemas de calidad educativa y de políticas de promoción de las carreras científicas.
Comunidad de educadores iberoamericanos para la cultura científica. Una red para la innovación
Authors: Martín Gordillo Mariano , Osorio Carlos
Published: October 2019

Desde 2009 está en marcha la Comunidad de Educadores Iberoamericanos para la Cultura Científica (CECC)1, una iniciativa promovida por el Centro de Altos Estudios Universitarios de la OEI2 en la que se integran docentes iberoamericanos que comparten el interés por promover la cultura científica en el ámbito educativo y el deseo de introducir nuevas estrategias didácticas. En este artículo se presentan algunos antecedentes que explican la conformación de esta comunidad, se describen las características de los materiales didácticos que se comparten en ella y se analizan algunos datos relevantes sobre su uso en las aulas. Todo ello mediante un trabajo de colaboración en red enmarcado en el horizonte del proyecto Metas Educativas 2021: la educación que queremos para la generación de los Bicentenarios3 y orientado al fortalecimiento de la cultura científica en Iberoamérica.
Educação do corpo, dor, sacrifício: um estudo com competidores de atletismo
Authors: Carreirão Gonçalves Michelle , Fernandez Vaz Alexandre
Published: October 2019

Resumen

Uma das questões que desafiam a compreensão do esporte contemporâneo diz respeito às relações do atleta com seu próprio corpo, ou, dito de outra forma, como ele significa a necessária instrumentalização corporal, exigência tanto do treinamento, quanto da performance competitiva. O atletismo aparece como uma das modalidades em que essas relações se colocam com maior clareza, talvez porque lhe seja menos frequente o momento de jogo presente em esportes coletivos. Nesse contexto, apresentamos os resultados de uma pesquisa com atletas adultos semi-profissionais de atletismo, com foco em técnicas e sacrifícios que permeiam o treinamento esportivo. Foram feitas observações sistemáticas de treinamentos e competições de atletas de pista, bem como entrevistas narrativas com protagonistas da modalidade. A análise específica de modalidades pode nos mostrar singularidades que se referem às formas de subjetivação contemporâneas. É este o caso, conforme mostram nossos resultados: (1) uma importante relação entre a técnica e a organização do sofrimento nos marcos do treinamento esportivo, com vistas ao disciplinamento, domínio e potencialização do corpo; (2) uma normalização da dor, entendida como parte fundamental da vitalidade atlética; (3) uma relação ambígua com as lesões – que deixam de ser um problema para tornar-se motivo de orgulho, criando um culto às lesões, uma celebração do sofrimento –,bem como com a ingestão de medicamentos para lidar com a dor – representando uma luta entre naturalidade e artificialidade.
Impacto de la tutoría presencial y virtual en el desempeño académico de alumnos universitarios
Authors: García López Ramona Imelda , Cuevas Salazar Omar , Vales García Javier José , Cruz Medina Isidro Roberto
Published: October 2019

Con la incorporación de las tecnologías de la información y la comunicación a la educación, los programas de tutorías en las universidades se han diversificado con la modalidad virtual. Esta diversificación ha permitido incrementar la cobertura y ofrecer el beneficio de los contenidos y actividades a los estudiantes que, por motivos de horario y distancia, no pueden inscribirse en la modalidad presencial de las tutorías.

Sin embargo, hasta el momento se desconoce si existe un efecto de la tutoría virtual en el aprovechamiento académico de los estudiantes y cómo resulta éste, comparado con la tutoría presencial. Es por ello que el objetivo de esta investigación fue, precisamente, determinar el impacto, posiblemente diferencial, que los programas de tutoría presencial y virtual de una universidad mexicana tienen sobre el desempeño académico de sus estudiantes.

Los resultados de este estudio muestran un impacto positivo, un incremento significativo en los promedios de calificaciones y en los porcentajes de aprobación en el semestre en donde los estudiantes cursaron tutorías en cualquiera de sus modalidades, presencial o virtual. Se encontró también que en el semestre en el que se cursaron tutorías, el promedio de las calificaciones de los alumnos que cursan tutoría virtual, fue mayor que el de los alumnos que cursaron tutoría presencial.
Políticas educativas y enseñanza agraria, una relación compleja. Buenos Aires (Argentina), 1960-2010
Authors: Gutiérrez Talía Violeta
Published: October 2019

En el ámbito de la provincia de Buenos Aires (Argentina), la que concentra el mayor peso socioeconómico y demográfico del país, este artículo analiza –con una perspectiva histórica, desde 1960 a 2010- la evolución de una específica modalidad educativa, la enseñanza agraria, caracterizada por cambios institucionales y curriculares, así como por situaciones disímiles de las escuelas en cuanto a historia, ubicación territorial, actitud de la comunidad y relación con otros actores. La dependencia tradicional de administraciones relacionadas con la producción (ministerios de agricultura o similares), se ve modificada en esta etapa, transfiriéndose a reparticiones educativas, a la vez que la descentralización del sistema educativo, en los años noventa, traslada las escuelas nacionales a las provincias. La marcada heterogeneidad e inestabilidad tiene un fuerte impacto en este tipo de enseñanza afectada, asimismo, por la necesidad de responder a múltiples demandas: de los actores sociales locales, del sistema productivo y compromisos políticos. Por esa razón, un estudio comparativo, y ejemplificado a través de algunos casos específicos, en profundidad histórica, permitirá comprender mejor las características de la educación agraria en la región pampeana, aportando al afianzamiento de esta modalidad educativa y a la conservación de una identidad propia, en el contexto de una nueva institucionalidad del subsistema en la provincia.
La numeración y el cálculo: dos caras de una misma moneda
Authors: Rizo Cabrera Celia , Campistrous Pérez Luis
Published: October 2019

Los problemas que presentan los estudiantes para calcular con números naturales, muchas veces se analizan enmarcados sólo en eso, es decir "en el cálculo", pero su origen es más complejo y está asociado a otros componentes de bases teóricas e históricas muy relacionados con la numeración. En este trabajo se presentan resultados de investigaciones realizadas por los autores, en los que se evidencia esta problemática, conocida pero aún no resuelta, de la "numeración y su impacto en el cálculo" y profundiza en aspectos que pueden contribuir a su solución.
