Clustering Based Physical-Layer Authentication in Edge Computing Systems with Asymmetric Resources
Authors: Chen Yi , Wen Hong , Wu Jinsong , Song Huanhuan , Xu Aidong , Jiang Yixin , Zhang Tengyue , Wang Zhen
Published: April 2019

In this paper, we propose a clustering based physical-layer authentication scheme (CPAS) to overcome the drawback of traditional cipher-based authentication schemes that suffer from heavy costs and are limited by energy-constrained intelligent devices. CPAS is a novel cross-layer secure authentication approach for edge computing system with asymmetric resources. The CPAS scheme combines clustering and lightweight symmetric cipher with physical-layer channel state information to provide two-way authentication between terminals and edge devices. By taking advantage of temporal and spatial uniqueness in physical layer channel responses, the non-cryptographic physical layer authentication techniques can achieve fast authentication. The lightweight symmetric cipher initiates user authentication at the start of a session to establish the trust connection. Based on theoretical analysis, the CPAS scheme is secure and simple, but there is no trusted party, while it can also resist small integer attacks, replay attacks, and spoofing attacks. Besides, experimental results show that the proposed scheme can boost the total success rate of access authentication and decrease the data frame loss rate, without notable increase in authentication latencies.

Authors: Jiang Xiantao , Feng Jie , Song Tian , Katayama Takafumi
Published: April 2019

Real-time video streaming over vehicular ad-hoc networks (VANETs) has been considered as a critical challenge for road safety applications. The purpose of this paper is to reduce the computation complexity of high efficiency video coding (HEVC) encoder for VANETs. Based on a novel spatiotemporal neighborhood set, firstly the coding tree unit depth decision algorithm is presented by controlling the depth search range. Secondly, a Bayesian classifier is used for the prediction unit decision for inter-prediction, and prior probability value is calculated by Gibbs Random Field model. Simulation results show that the overall algorithm can significantly reduce encoding time with a reasonably low loss in encoding efficiency. Compared to HEVC reference software HM16.0, the encoding time is reduced by up to 63.96%, while the Bjontegaard delta bit-rate is increased by only 0.76–0.80% on average. Moreover, the proposed HEVC encoder is low-complexity and hardware-friendly for video codecs that reside on mobile vehicles for VANETs.
A Submersible Printed Sensor Based on a Monopole-Coupled Split Ring Resonator for Permittivity Characterization
Authors: Reyes-Vera Erick , Acevedo-Osorio G. , Arias-Correa Mauricio , Senior David E.
Published: April 2019

This work presents a non-invasive, reusable and submersible permittivity sensor that uses a microwave technique for the dielectric characterization of liquid materials. The proposed device consists of a compact split ring resonator excited by two integrated monopole antennas. The sensing principle is based on the notch introduced by the resonators in the transmission coefficient, which is affected due to the introduction of the sensor in a new liquid material. Then, a frequency shift of the notch and the Q-factor of the proposed sensor are related with the changes in the surrounding medium. By means of a particular experimental procedure, commercial liquids are employed to obtain the calibration curve. Thus, a mathematical equation is obtained to extract the dielectric permittivity of liquid materials with unknown dielectric properties. A good match between simulated and experimental results is obtained, as well as a high Q-factor, compact size, good sensitivity and high repeatability for use in sensing applications. Sensors like the one here presented could lead to promising solutions for characterizing materials, particularly in determining material properties and quality in the food industry, bio-sensing and other applications.
A Novel Four Single-Sideband M-QAM Modulation Scheme Using a Shadow Equalizer for MIMO System Toward 5G Communications
Authors: Alhasani Mohammed Mustafa , Nguyen Quang Ngoc , Ohta Gen-Ichiro , Sato Takuro
Published: April 2019

Single-sideband (SSB) modulation through Hilbert transformation has successfully transmitted data using only half the bandwidth of the traditional scheme for the same amount of contained information. Toward this end, the four single-sideband (4-SSB) approach for high order modulation is a promising approach for the next-generation communications by applying soft-input soft-output (SISO) equalizer algorithms over orthogonal frequency division multiplexing (OFDM). However, OFDM is challenging for realizing the feasible 5G communications, compared to the emerging techniques, e.g., non-orthogonal multiple access (NOMA), orthogonal multiple access (OMA) or multiple-input multiple-output (MIMO). Since the 4-SSB is an orthogonal modulation which was successfully applied over the traditional OFDM, in this article, we propose a novel 4-SSB modulation scheme over OFDM Guard Interval (GI) and massive MIMO. Besides the carrier signal, from the receiver side, we also apply the shadow equalizer algorithm in the uncoded and coded environment using turbo codes to achieve the 4-SSB with high efficiency from low complexity and energy consumption for 5G. The evaluation results validate that our system consumes lower energy due to low complexity gained from same number of iterations without the heavy decoding as of the 4-SSB SISO based on the turbo equalizer. In addition, the 4-SSB over the OFDM GI achieves the best performance among the relevant approaches conducted in 4-SSB. The proposal then acts as a practical communication system designed to solve the inter-symbol interference (ISI) induced by additional Hilbert transform in the wireless environment toward fifth generation (5G), given that turbo code is considered as a potential channel coding scheme for 5G radio specification.
A Joint Method Based on Time-Frequency Distribution to Detect Time-Varying Interferences for GNSS Receivers with a Single Antenna
Authors: Lv Qingshui , Qin Honglei
Published: April 2019

In this paper, a joint method combining Hough transform and reassigned smoothed pseudo Wigner-Ville distribution (RSPWVD) is presented to detect time-varying interferences with crossed frequency for a Global Navigation Satellite System (GNSS) receiver with a single antenna. The proposed method can prevent the cross-term interference and detect the time-varying interferences with crossed frequency which cannot be achieved by the classical time-frequency (TF) analysis with the peak detection method. The actual performance of the developed method has been evaluated by experiments with conditions where the real BeiDou system (BDS) B1I signals are corrupted by the simulated chirp interferences. The results of experiments show that the introduced method is effectively able to detect chirp interferences with crossed frequency and provide the same root mean square errors (RMSE) of the parameter estimation for chirp one and the improved initial frequency estimation for chirp two compared with the Hough transform of Wigner-Ville distribution (WVD) when the jamming to noise ratio (JNR) equals or surpasses 4 dB.

Published: April 2019

Conventional pattern-recognition algorithms for surface electromyography (sEMG)-based hand-gesture classification have difficulties in capturing the complexity and variability of sEMG. The deep structures of deep learning enable the method to learn high-level features of data to improve both accuracy and robustness of a classification. However, the features learned through deep learning are incomprehensible, and this issue has precluded the use of deep learning in clinical applications where model comprehension is required. In this paper, a generative flow model (GFM), which is a recent flourishing branch of deep learning, is used with a SoftMax classifier for hand-gesture classification. The proposed approach achieves 63.86 ± 5.12 % accuracy in classifying 53 different hand gestures from the NinaPro database 5. The distribution of all 53 hand gestures is modelled by the GFM, and each dimension of the feature learned by the GFM is comprehensible using the reverse flow of the GFM. Moreover, the feature appears to be related to muscle synergy to some extent.

Published: April 2019

To achieve the full analytical potential of the streaming data from the internet of things, the interconnection of various data sources is needed. By definition, those sources are heterogeneous and their integration is not a trivial task. A common approach to exploit streaming sensor data potential is to use machine learning techniques for predictive analytics in a way that is agnostic to the domain knowledge. Such an approach can be easily integrated in various use cases. In this paper, we propose a novel framework for data fusion of a set of heterogeneous data streams. The proposed framework enriches streaming sensor data with the contextual and historical information relevant for describing the underlying processes. The final result of the framework is a feature vector, ready to be used in a machine learning algorithm. The framework has been applied to a cloud and to an edge device. In the latter case, incremental learning capabilities have been demonstrated. The reported results illustrate a significant improvement of data-driven models, applied to sensor streams. Beside higher accuracy of the models the platform offers easy setup and thus fast prototyping capabilities in real-world applications.
The Effect of Gamma Irradiation on the Ion Exchange Properties of Caesium-Selective Ammonium Phosphomolybdate-Polyacrylonitrile (AMP-PAN) Composites under Spent Fuel Recycling Conditions
Authors: Holdsworth Alistair F. , Eccles Harry , Rowbotham Daniel , Bond Gary , Kavi Parthiv C. , Edge Ruth
Published: April 2019

The caesium radioisotopes 134Cs, 135Cs, and 137Cs are highly problematic medium-lived species produced during nuclear fission, due to their high radioactivity and environmental mobility. While many ion exchange materials can readily isolate Cs+ ions from neutral or basic aqueous solutions, only ammonium phosphomolybdate (AMP) functions effectively in acidic conditions, removing caesium even down to trace levels. Composites of AMP in a porous polymeric support such as polyacrylonitrile (PAN) can be used to selectively remove Cs+ ions from acidic aqueous decontamination liquors as well as other liquid wastes, and are promising for the isolation of Cs+ isotopes in spent fuel reprocessing. While both AMP and PAN have demonstrable acid stability, and PAN has known resistance to gamma radiation, AMP-PAN composites have received only a limited analysis of their physiochemical and ion exchange performance following irradiation. In this publication, we explore the effect of high levels of gamma irradiation on the ion exchange properties of AMP and AMP-PAN as a Cs+-selective adsorbent under spent fuel dissolver liquor concentrations and acidity. We demonstrate no significant reduction in performance with respect to uptake kinetics or capacity upon irradiation, abiding by the same absorption mechanism observed in the established literature.
Renewable Energy Development as a Driver of Economic Growth: Evidence from Multivariate Panel Data Analysis
Authors: Singh Nadia , Nyuur Richard , Richmond Ben
Published: April 2019

Renewable energy is being increasingly touted as the “fuel of the future,” which will help to reconcile the prerogatives of high economic growth and an economically friendly development trajectory. This paper seeks to examine relationships between renewable energy production and economic growth and the differential impact on both developed and developing economies. We employed the Fully Modified Ordinary Least Square (FMOLS) regression model to a sample of 20 developed and developing countries for the period 1995–2016. Our key empirical findings reveal that renewable energy production is associated with a positive and statistically significant impact on economic growth in both developed and developing countries for the period 1995–2016. Our results also show that the impact of renewable energy production on economic growth is higher in developing economies, as compared to developed economies. In developed countries, an increase in renewable energy production leads to a 0.07 per cent rise in output, compared to only 0.05 per cent rise in output for developing countries. These findings have important implications for policymakers and reveal that renewable energy production can offer an environmentally sustainable means of economic growth in the future.
An Empirical Study on User Experience Evaluation and Identification of Critical UX Issues
Authors: Feng Lin , Wei Wei
Published: April 2019

We introduce an approach that supports researchers and practitioners to determine the quality of first-time user experience (FTUX) and long-term user experience (LTUX), as well as to identify critical issues with these two types of UX. The product we chose to study is a mobile fitness application. Mobile apps tend to have a much shorter service life than most other products; thus, the developers/designers need to pay great attention to both first-time and long-term user experience. This study is based on a multi-method approach. We employed the AttrakDiff questionnaire to assess users’ first impressions of the app, and the UX Curve method to evaluate how users’ experience of the app has changed over time. Besides the quantitative data, which helped to determine the quality of user experience, we also collected qualitative data during two interviews with participants, and focused on the issues that predominantly deteriorated user experience. A four-coordinate plane tool was designed later in the data analysis process that combined the two kinds of user experience data at the same time, which led to a qualitative positioning of the user experience status of a certain product. The model was further successfully adopted in the identification of user experience issues of an online fitness application.
Attention Combines Similarly in Covert and Overt Conditions
Authors: Blair Christopher D. , Ristic Jelena
Published: April 2019

Attention is classically classified according to mode of engagement into voluntary and reflexive, and type of operation into covert and overt. The first distinguishes whether attention is elicited intentionally or by unexpected events; the second, whether attention is directed with or without eye movements. Recently, this taxonomy has been expanded to include automated orienting engaged by overlearned symbols and combined attention engaged by a combination of several modes of function. However, so far, combined effects were demonstrated in covert conditions only, and, thus, here we examined if attentional modes combined in overt responses as well. To do so, we elicited automated, voluntary, and combined orienting in covert, i.e., when participants responded manually and maintained central fixation, and overt cases, i.e., when they responded by looking. The data indicated typical effects for automated and voluntary conditions in both covert and overt data, with the magnitudes of the combined effect larger than the magnitude of each mode alone as well as their additive sum. No differences in the combined effects emerged across covert and overt conditions. As such, these results show that attentional systems combine similarly in covert and overt responses and highlight attention’s dynamic flexibility in facilitating human behavior.
Structural and optical properties of penicillamine-protected gold nanocluster fractions separated by sequential size-selective fractionation

Published: April 2019

Polydisperse water-soluble gold nanoclusters (AuNCs) protected by penicillamine have been synthesized in this work. The sequential size-selective precipitation (SSSP) technique has been applied for the size fractionation and purification of the monolayer-protected AuNCs. Through continuously adding acetone to a crude AuNC aqueous solution and controlling the volume percentage of acetone, we successfully separated the polydisperse AuNCs with diameters ranging from 0.5 to 5.4 nm into four different fractions sequentially. High-resolution transmission electron microscopy (HRTEM) shows that the four fractions are well-dispersed spherical particles of diameter 3.0 ± 0.6, 2.3 ± 0.5, 1.7 ± 0.4, and 1.2 ± 0.4 nm. Proton nuclear magnetic resonance spectroscopy suggests that disulfide, excess ligands and gold(I) complexes were removed from the AuNCs fractions. These results demonstrate the considerable potential of the SSSP technique for size-based separation and purification of AuNCs, achieving not only the isolation of larger nanoclusters (NCs) from small NCs in a continuous fashion, but also for the removal of small-molecule impurities. Based on the results from the mass spectrometry and thermogravimetric analysis, the average composition of the four fractions can be represented by Au38(SR)18, Au28(SR)15, Au18(SR)12, and Au11(SR)8, respectively. This indicates that the SSSP separation is mainly dependent on the core size and the ratio of Au atoms to ligands of AuNCs. X-ray photoelectron spectroscopy (XPS) has also been applied to observe the molecular dependence on the gold and sulfur chemical state of organosulfur monolayers of the fractions. The photoluminescence spectra of these AuNCs in the range of 900–790 nm was investigated at room temperature. The results show that the peak emission energy of the size-selected AuNCs undergoes a blue shift when the size is decreased, which can be attributed to the quantum confinement effect.
Notes on the biology, morphology and generic placement of “Hellwigia” obscura Gravenhorst (Hymenoptera: Ichneumonidae, Ophioninae)
Authors: Shaw Mark R. , Voogd Jeroen
Published: April 2019

The ophionine ichneumonid known as Hellwigiaobscura has been reared for the first time, from larvae of Horisme sp. (Lepidoptera: Geometridae) feeding on Clematisvitalba in The Netherlands. The cocoon and the parasitoid’s means of emergence are figured, as are some features of the adult. On a balance of morphological grounds, including some already discussed in the literature, it is proposed that “Hellwigia” obscura should be excluded from Hellwigia and instead be ascribed to the genus Heinrichiellastat. rev. as Heinrichiellaobscuracomb. n. Reasons for this change as well as for preferring this generic name to Protohellwigia Brues are given
L’éthique comme « seconde liturgie » chez Jean-Yves Lacoste
Authors: McKeever Martin
Published: April 2019

Que la liturgie ait, ou devrait avoir, un lien avec l’éthique est, nous l’espérons, au-delà de toute discussion. Dans Expérience et Absolu , Jean-Yves Lacoste arrive à une conclusion bien plus radicale, à savoir que l’éthique est une forme de liturgie. Pour comprendre cette affirmation, l’article se penche sur les termes « liturgie » et « éthique » chez Lacoste. Si sa façon de comprendre l’éthique est plus ou moins conventionnelle, sa conception de la liturgie est hautement originale. La thèse principale de Expérience et Absolu concerne le lien entre la facticité (propre à Heidegger) et la transcendance. Tout en exposant cette thèse, l’auteur propose une thèse supplémentaire concernant le rapport intime entre liturgie et éthique.
A Risk Framework for Munitions and Explosives of Concern in Support of U.S. Offshore Wind Energy Development
Authors: Carton Geoffrey , DuVal Carter , Trembanis Arthur
Published: April 2019

AbstractMunitions and explosives of concern (MEC) in U.S. waters can present a risk to the development and operation of offshore wind energy resources. Therefore, the U.S. Bureau of Ocean Energy Management requires offshore wind energy developers to evaluate the risk MEC
poses to the development, operation, and maintenance of offshore wind energy generation and transmission systems. This article describes an MEC risk management framework consisting of the following steps: (1) MEC hazard assessment, (2) MEC risk assessment, (3) MEC risk validation, and (4)
MEC risk mitigation. The MEC hazard assessment involves historical research to identify MEC potentially present in the development area. The MEC risk assessment evaluates the development activities and provides a relative MEC risk ranking for those activities. The developer determines the
acceptability of these risks, and any potentially unacceptable MEC risks undergo risk validation through field surveys. The developer then considers the tolerability of the validated risks and develops and implements an appropriate MEC risk mitigation strategy based on actual site conditions.
A risk framework provides a structured method to plan and operationalize the identification, evaluation, and mitigation of MEC risk throughout the development, operation, and maintenance life cycle of an offshore wind energy generation and transmission project.
Success in Africa: People with disabilities share their stories
Authors: Shakespeare Tom , Mugeere Anthony , Nyariki Emily , Simbaya Joseph
Published: April 2019

Background: Whereas most narratives of disability in sub-Saharan Africa stress barriers and exclusion, Africans with disabilities appear to show resilience and some appear to achieve success. In order to promote inclusion in development efforts, there is a need to challenge narratives of failure.Objectives: To gather life histories of people with disabilities in three sub-Saharan African countries (Kenya, Uganda and Sierra Leone) who have achieved economic success in their lives and to analyse factors that explain how this success has been achieved.Methods: Qualitative research study of economic success involving life history interviews with 105 participants with disabilities from both urban and rural settings recruited through disabled people’s organisations and non-governmental organisation partners, framework analysis of transcripts to chart success and success factors.Results: Participants had faced barriers in education, employment and family life. They had largely surmounted these barriers to achieve success on an equal basis with others. They were working in private and public sectors and were self-employed farmers, shopkeepers and craftspeople.Conclusion: The findings of this study suggest that, given the right support, disabled people can achieve economic success, with the implication being that investment in education or training of disabled people can be productive and should be part of overall development efforts for economic reasons, not solely to achieve social justice goals.

Impact of poleward heat and moisture transports on Arctic clouds and climate simulation
Authors: Baek Eun-Hyuk , Kim Joo-Hong , Park Sungsu , Kim Baek-Min , Jeong Jee-Hoon
Published: April 2019

Abstract. Clouds play an important role in regulating the Earth's global radiation budget. Many General Circulation Models (GCMs) have difficulty in simulating Arctic clouds and climate with a large inter-model spread. In an attempt to address this issue, we compare an Atmospheric Model Inter-comparison Project (AMIP) simulation from the Community Atmosphere Model version 5 (CAM5) with that from the Seoul National University (SNU) Atmosphere Model version 0 with a Unified Convection Scheme (SAM0). Over the Arctic, it was found that SAM0 simulates more cloud fraction and cloud liquid mass than CAM5, reducing the Arctic clouds biases in CAM5. The budget analysis indicates that this improvement is associated with an enhanced net condensation rate of water vapor into the liquid condensate of the Arctic low-level stratus, which in turn is driven by enhanced poleward transports of heat and moisture by mean meridional circulation and transient eddies. The reduced Arctic cloud biases lead to improved simulations of surface radiation fluxes and near-surface air temperature over the Arctic throughout the year. The association between the enhanced poleward transports of heat and moisture and more liquid stratus over the Arctic is also evident in the multi-models analysis. Our study indicates that the proper simulation of poleward heat and moisture transport is one of the key factors necessary for improving the simulations of Arctic clouds and climate.
Optical properties of meteoric smoke analogues

Published: April 2019

Abstract. Accurate determination of the optical properties of analogues for meteoric smoke particles (MSPs), which are thought to be composed of iron-rich oxides or silicates, is important for their observation and characterization in the atmosphere. In this study, a photochemical aerosol flow reactor (PAFS) has been used to measure the optical extinction of iron oxide MSP analogues in the wavelength range 325–675 nm. The particles were made photochemically, and agglomerate into fractal-like particles with sizes on the order of 100 nm. Analysis using Transmission Electron Microscopy (TEM), Energy Dispersive X-ray spectroscopy (EDX) and Electron Energy Loss Spectroscopy (EELS) suggested the particles were most likely maghemite-like (γ-Fe2O3) in composition. The optical extinction coefficients measured using the PAFS were then combined with maghemite absorption coefficients measured using a complementary experimental system, the MICE-TRAPS, to derive complex refractive indices which are able to reproduce both the measured absorption and extinction.
Human influence on European winter wind storms such as those of January 2018

Abstract. Several major storms pounded western Europe in January 2018, generating large damages and casualties.
The two most impactful ones,
Eleanor and Friederike, are analysed here in the context of climate change.
Near surface wind speed station observations exhibit a decreasing trend in
the frequency of strong winds associated with such storms. High-resolution
regional climate models, on the other hand, show no trend up to now and a
small increase in storminess in future due to climate change. This shows
that factors other than climate change, which are not in the climate
models, caused the observed decline in storminess over land. A large part is
probably due to increases in surface roughness, as shown for a small set of
stations covering the Netherlands and in previous studies. This observed
trend could therefore be independent from climate evolution. We concluded
that human-induced climate change has had so far no significant influence on
storms like the two mentioned. However, all simulations indicate that global warming
could lead to a marginal increase (0 %–20 %) in the probability of extreme
hourly winds until the middle of the century, consistent with previous
modelling studies. This excludes other factors, such as surface roughness,
aerosols, and decadal variability, which have up to now caused a much larger
negative trend. Until these factors are correctly simulated by climate
models, we cannot give credible projections of future storminess over
land in Europe.
The Ulakhan fault surface rupture and the seismicity of the Okhotsk–North America plate boundary
Authors: Hindle David , Sedov Boris , Lindauer Susanne , Mackey Kevin
Published: April 2019

Abstract. New field work, combined with analysis of high-resolution aerial photographs, digital elevation models, and satellite imagery, has identified an
active fault that is traceable for ∼90 km across the Seymchan Basin
and is part of the Ulakhan fault system, which is believed to form the
Okhotsk–North America plate boundary. Age dating of alluvial fan sediments
in a channel system that is disturbed by fault activity suggests the current
scarp is a result of a series of large earthquakes (≥Mw 7.5)
that have occurred since 11.6±2.7 ka. A possible channel feature offset
by 62±4 m associated with these sediments yields a slip rate of 5.3±1.3 mm yr−1, in broad agreement with rates suggested from global
plate tectonics. Our results clearly identify the Ulakhan fault as the
Okhotsk–North America plate boundary and show that tectonic strain release
is strongly concentrated on the boundaries of Okhotsk. In light of our
results, the likelihood of recurrence of Mw 7.5 earthquakes is
high, suggesting a previously underestimated seismic hazard across the
region.

Published: April 2019

This study investigated the impact of core drivers of job satisfaction including promotions, increment and bonuses, supervisor’s’ support, career development and advancement opportunities and working conditions on two dependent variables i.e. job performance and employees retention. For this purpose a comparative study is conducted in education and banking sector of Karachi. A sample of 100 employees was collected from each sector then results were analyzed through Confirmatory Factor Analysis and Structural Equation Modeling. The results found both the education and banking sectors are different in terms of chosen human resource policies Secondly, it has been found that results are dissimilar for both sectors in terms of different hypotheses. Career development, compensation and promotions are insignificant key divers of job satisfaction for job performance. While, working conditions, compensations and co-workers are insignificant key divers of job satisfaction for employees’ retention. Result’s implication is different for banks’ managers and educational institutions’ managers based on significance of coefficients however human resource policies vary in different business settings. Indeed, more the job satisfaction better chance of good employees’ performance while it reduces the intention to switch and keep the human talent retained.
La actuación de diplomáticos latinoamericanos en el salvamento de judío en la Segunda Guerra Mundial
Authors: Zadoff Efraim
Published: April 2019

La actitud de los países de América Latina hacia los judíos durante la Shoá se desarrolló a dos niveles: las posibilidades de inmigración que oficial o extraoficialmente brindaron estos países a los refugiados judíos desde 1933 a 1945; el otorgamiento de pasaportes y documentos de protección que podían resguardar a judíos de la persecución, la deportación y el exterminio.

Este trabajo es parte de una investigación más amplia que se ocupa del segundo tema.

Generalmente la acción de otorgar pasaportes para salvar judíos fue asumida por algunos diplomáticos latinoamericanos sin consultar con sus gobiernos y a veces en contra de su política. Algunos de ellos arriesgaron y perdieron su carrera por esta actuación netamente

humanitaria. Hasta el momento se han realizado investigaciones sobre los cónsules de Ecuador, Manuel Antonio Muñoz Borrero; de El Salvador, José Arturo Castellanos, y de Perú, José María Barreto, los tres reconocidos por Yad Vashem como Justos de las Naciones.

Destellos de nostalgia: inmigrantes ideológicos de América Latina en el Israel de hoy
Authors: Siebzehner Batia
Published: April 2019

La práctica de la ideología sionista socialista que caracterizaba a los movimientos juveniles en América Latina implicó para sus miembros emigrar a Israel y vivir en el kibutz. Este artículo analiza la manera en que los grupos de Hashomer Hatzair que emigraron en los decenios de los 50 a los 80 del siglo XX evalúan en la madurez (la segunda década del siglo XXI) la realización de esos objetivos. El cuestionario al que respondieron más de 700 personas que participaron en el movimiento y emigraron a Israel y las entrevistas realizadas a parte de ellos tomaron en consideración los cambios acaecidos en la sociedad israelí desde entonces. Los hallazgos muestran que hay casi un consenso entre los encuestados en lo que se refiere al logro de los objetivos sionistas y a la contribución del movimiento a la conformación de la nacionalidad israelí. Las

respuestas que se refieren al kibutz presentan un cuadro más complejo dado que hay quienes ven en esa empresa un fracaso y hay también quienes consideran un posible despertar del socialismo y el colectivo kibutziano.

La decepción, e incluso los perjuicios personales parecen no destruir la nostalgia restaurativa con respecto al movimiento juvenil al que le atribuyen un lugar fundamental como vivencia juvenil. Tanto los miembros que aún viven en el kibutz (la mitad de los respondientes) como los que lo abandonaron volverían, con la experiencia actual, a ingresar al movimiento que parece.
El uso del hiyab a la luz de los nuevos tiempos y su relación con los DD.HH
Authors: Torres Alejandra
Published: April 2019

La religión islámica ha generado y sigue generando debates. Esta vez es la prohibición del velo islámico (hiyab) en algunos países europeos, especialmente Francia y España, ambos con un alto porcentaje de inmigrantes, pero también de ciudadanos islámicos que exigen que sus derechos fundamentales se respeten. Es en este punto donde chocan principalmente las posturas a favor de su prohibición, ya que sería inconstitucional que un Estado se manifestara en contra de su uso, obligando a las mujeres a no cubrir sus cabellos, atentando contra la libertad de manifestar públicamente su religión. Es en este debate en que gira esta ponencia, describiendo distintas posturas de feministas laicas y musulmanas, además de intelectuales que se cuestionan si la utilización del velo es la que atenta contra los derechos humanos o su prohibición.

La política inmigratoria a Chile durante la época previa y durante la Segunda Guerra Mundial fue bastante restrictiva, con excepción de la primera etapa del gobierno de Pedro Aguirre Cerda, quien abrió las puertas a todos los oprimidos y perseguidos, pero luego optó por restringir la inmigración debido a presiones de la prensa y de grupos opositores. Junto al Presidente Aguirre Cerda obtuvieron bancada tres diputados de origen judío, uno de ellos, Natalio Berman, tuvo un activo rol en la política inmigratoria y en la autorización de la llegada de barcos con refugiados judíos al país, aún después del cierre de las fronteras. En el presente artículo se revisa el marco histórico- político que reinaba en Chile el periodo de la segunda guerra mundial y se subraya la labor de Natalio Berman, destacado médico, escritor, líder comunitario y dirigente político.

Baumany Buber: hacia una ética de la responsabilidad
Authors: Calderón Paula
Published: April 2019

En este trabajo realizaremos un breve diagnóstico de la crisis de la modernidad, tal como lo plantea el pensador judío Zygmunt Bauman, haciendo alusión a la noción de “modernidad líquida”, la que de acuerdo con el autor se caracteriza por una precariedad de los vínculos humanos, marcada por el carácter transitorio y volátil de sus relaciones, incluido el vínculo con lo religioso. Donde el hombre, de acuerdo con el pensador, se encuentra atrapado en la tecnología, en relaciones que se tornan desechables y donde prima el individualismo por sobre lo colectivo.

En este escenario de época técnica, haremos alusión a su vez a ciertas propuestas que plantea el pensador judeo alemán Martín Buber, con tal de recuperar los vínculos con lo sagrado y lograr salir de estos tiempos de emergencia. El pensador plantea un giro hacia el otro a través del diálogo, lo que se traduce en un movimiento desde la unicidad a la multiplicidad, es decir, desde el pensamiento centrado en el “yo-eso”, hacia el pensamiento “yo-tú”, el que permite un diálogo genuino y trascendente con las personas, la naturaleza y, sobre todo, con Dios.
Revalorización de los sofistas
Authors: Samour Héctor
Published: April 2019

El artículo hace una revisión minuciosa en torno al pensamiento de los sofistas, con el fin de mostrar que su filosofía constituye uno de los momentos claves de la historia de la filosofía griega. Lejos de ser un grupo de pensadores superficiales con un absurdo afán de destruir todo fundamento de una auténtica filosofía, los sofistas aparecen como los iniciadores de un giro decisivo en la historia del pensamiento humano, que puso en primer plano los problemas de la vida social y ética, junto con el esclarecimiento de lo que fuesen las leyes y las normas morales, así como de la inserción del ser humano en su medio histórico y natural.
El humanismo ante los desafíos actuales : una mirada desde la antropología
Authors: Rivas Ramón Douglas
Published: April 2019

En esta reﬂexión se considera que para que el humanismo sea un camino social para la pacificación, el desarrollo y el crecimiento cultural, es necesario y urgente potenciar el conocimiento en todos los sectores de la vida. No podemos seguir tomando decisiones personales y colectivas sin tener conocimiento de las cosas, sus consecuencias y sus beneficios. Se necesitan más hombres y mujeres que razonen o contemplen la vida para reﬂexionar de ella. Es el momento para repensar la educación básica, media y universitaria.
Reseña de Mariona… vivir allí

En todas las sociedades civilizadas del mundo existen centros penales; son una “necesidad”. En los países desarrollados, las penitenciarías son mejor estructuradas para cumplir con sus supuestos propósitos: reeducar a los delincuentes o que paguen con muchas restricciones, a veces por largos años, o hasta con sus vidas, según sea la gravedad de sus crímenes. De hecho, la cantidad de malhechores es proporcional a la de sus grandes poblaciones.En los pueblos conocidos como «en vías de desarrollo», las condiciones de las cárceles son precarias, y algunas carecen de programas para que los reos que pasan a la fase de confianza o que ya cumplieron sus penas se reinserten a la vida cotidiana normal con la seguridad de que no volverán a cometer ningún delito en contra de sus semejantes, esto en términos generales. Por supuesto que las estadísticas globales siempre reﬂejarán porcentajes considerables de personas que han cometido errores, conscientes o inconscientes, que han rehecho sus vidas para el bien propio, el de sus familias y el de la ciudadanía.El sistema carcelario salvadoreño alberga muchos miles de presos, incluyendo a las mujeres, que son un asunto aparte. Según el Instituto Latinoamericano de las Naciones Unidas para la Prevención del Delito y Tratamiento del Delincuente, El Salvador es uno de los países con mayor nivel de hacinamiento [248 %] (La Prensa Gráfica, 17 de junio de 2017). La Constitución de la República de El Salvador, en el artículo 27, dice que «el Estado organizará los centros penitenciarios con objeto de corregir a los delincuentes, educarlos»; centros que son de distintos tipos en todo el país. En ese sentido, con el correr del tiempo las cosas han ido cambiando con algunos avances positivos. Por ejemplo, en opinión del entonces director general de Centros Penales, «el programa de rehabilitación “Yo Cambio” se ha convertido en un modelo de gestión penitenciaria» (www.presidencia.gob.sv. 8 de abril de 2015). Así como con otras medidas, la creación de granjas y la celebración de ciertos actos culturales. Lo último que se ha informado por parte de la Dirección General de Centros Penales es la apertura de la Unidad Penitenciaria de Derechos Humanos y de la Oficina de Información Penitenciaria.

Cuando el explorador Juan Ponce de León arribó a esta costa atlántica el 2 de abril de 1513 ignoraba que estaba dando un paso histórico de profundas repercusiones lingüísticas. Supuestamente buscaba la fuente de la eterna juventud, que según una leyenda tahína se encontraba en estos alrededores. En su ruta divisó una tierra que llamó Florida, debido a la vegetación en ﬂor que vio o porque era tiempo de Pascua Florida.

To meet such expectations, the auditor must possess specific skills and qualifications.
NEW DEAL FOR CONSUMERS IN EUROPE?
Authors: Mokrysz-Olszyńska Anna
Published: April 2019

On 11 April 2018, the European Commission presented legislative proposals as the implementation of the project under the title “A New Deal for Consumers”. The Commission’s legislative package consists of related proposals for two directives. The first contains provisions enabling authorized entities representing the collective consumer interest to pursue claims through representative actions against infringements of Union law, in order to ensure that consumers have the tools to effectively exercise their rights and obtain compensation for the damage suffered; the second introduces changes to the four currently applicable consumer directives. Both Commission proposals are under way, taking into account broad public consultation. Do the Commission’s proposals mean a real breakthrough, as suggested by the title under which they are presented, or should they be seen only as the next step in the process of creating a new order for consumers?
