Barrier Coverage for 3D Camera Sensor Networks
Authors: Si Pengju , Wu Chengdong , Zhang Yunzhou , Jia Zixi , Ji Peng , Chu Hao
Published: August 2017

Barrier coverage, an important research area with respect to camera sensor networks, consists of a number of camera sensors to detect intruders that pass through the barrier area. Existing works on barrier coverage such as local face-view barrier coverage and full-view barrier coverage typically assume that each intruder is considered as a point. However, the crucial feature (e.g., size) of the intruder should be taken into account in the real-world applications. In this paper, we propose a realistic resolution criterion based on a three-dimensional (3D) sensing model of a camera sensor for capturing the intruder’s face. Based on the new resolution criterion, we study the barrier coverage of a feasible deployment strategy in camera sensor networks. Performance results demonstrate that our barrier coverage with more practical considerations is capable of providing a desirable surveillance level. Moreover, compared with local face-view barrier coverage and full-view barrier coverage, our barrier coverage is more reasonable and closer to reality. To the best of our knowledge, our work is the first to propose barrier coverage for 3D camera sensor networks.
Accuracy Analysis of a Dam Model from Drone Surveys
Authors: Ridolfi Elena , Buffi Giulia , Venturi Sara , Manciola Piergiorgio
Published: August 2017

This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D) model. Images of a double arch masonry dam upstream face are acquired from drone survey and used to build the 3D model of the dam for vulnerability analysis purposes. However, there still remained the issue of understanding the real impact of a correct GCPs location choice to properly georeference the images and thus, the model. To this end, a high number of GCPs configurations were investigated, building a series of dense point clouds. The accuracy of these resulting dense clouds was estimated comparing the coordinates of check points extracted from the model and their true coordinates measured via traditional topography. The paper aims at providing information about the optimal choice of GCPs placement not only for dams but also for all surveys of high-rise structures. The knowledge a priori of the effect of the GCPs number and location on the model accuracy can increase survey reliability and accuracy and speed up the survey set-up operations.

Published: August 2017

Methods for estimating a car’s length are presented in this paper, as well as the results achieved by using a self-designed system equipped with two anisotropic magneto-resistive (AMR) sensors, which were placed on a road lane. The purpose of the research was to compare the lengths of mid-size cars, i.e., family cars (hatchbacks), saloons (sedans), station wagons and SUVs. Four methods were used in the research: a simple threshold based method, a threshold method based on moving average and standard deviation, a two-extreme-peak detection method and a method based on the amplitude and time normalization using linear extrapolation (or interpolation). The results were achieved by analyzing changes in the magnitude and in the absolute z-component of the magnetic field as well. The tests, which were performed in four different Earth directions, show differences in the values of estimated lengths. The magnitude-based results in the case when cars drove from the South to the North direction were even up to 1.2 m higher than the other results achieved using the threshold methods. Smaller differences in lengths were observed when the distances were measured between two extreme peaks in the car magnetic signatures. The results were summarized in tables and the errors of estimated lengths were presented. The maximal errors, related to real lengths, were up to 22%.
Direction-of-Arrival Estimation with Coarray ESPRIT for Coprime Array
Authors: Zhou Chengwei , Zhou Jinfang
Published: August 2017

A coprime array is capable of achieving more degrees-of-freedom for direction-of-arrival (DOA) estimation than a uniform linear array when utilizing the same number of sensors. However, existing algorithms exploiting coprime array usually adopt predefined spatial sampling grids for optimization problem design or include spectrum peak search process for DOA estimation, resulting in the contradiction between estimation performance and computational complexity. To address this problem, we introduce the Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) to the coprime coarray domain, and propose a novel coarray ESPRIT-based DOA estimation algorithm to efficiently retrieve the off-grid DOAs. Specifically, the coprime coarray statistics are derived according to the received signals from a coprime array to ensure the degrees-of-freedom (DOF) superiority, where a pair of shift invariant uniform linear subarrays is extracted. The rotational invariance of the signal subspaces corresponding to the underlying subarrays is then investigated based on the coprime coarray covariance matrix, and the incorporation of ESPRIT in the coarray domain makes it feasible to formulate the closed-form solution for DOA estimation. Theoretical analyses and simulation results verify the efficiency and the effectiveness of the proposed DOA estimation algorithm.

Published: August 2017

To address the need for asthma self-management in pediatrics, the authors present the feasibility of a mobile health (mHealth) platform built on their prior work in an asthmatic adult and child. Real-time asthma attack risk was assessed through physiological and environmental sensors. Data were sent to a cloud via a smartwatch application (app) using Health Insurance Portability and Accountability Act (HIPAA)-compliant cryptography and combined with online source data. A risk level (high, medium or low) was determined using a random forest classifier and then sent to the app to be visualized as animated dragon graphics for easy interpretation by children. The feasibility of the system was first tested on an adult with moderate asthma, then usability was examined on a child with mild asthma over several weeks. It was found during feasibility testing that the system is able to assess asthma risk with 80.10 ± 14.13% accuracy. During usability testing, it was able to continuously collect sensor data, and the child was able to wear, easily understand and enjoy the use of the system. If tested in more individuals, this system may lead to an effective self-management program that can reduce hospitalization in those who suffer from asthma.

Authors: Jawad Haider , Nordin Rosdiadee , Gharghan Sadik , Jawad Aqeel , Ismail Mahamod
Published: August 2017

Wireless sensor networks (WSNs) can be used in agriculture to provide farmers with a large amount of information. Precision agriculture (PA) is a management strategy that employs information technology to improve quality and production. Utilizing wireless sensor technologies and management tools can lead to a highly effective, green agriculture. Based on PA management, the same routine to a crop regardless of site environments can be avoided. From several perspectives, field management can improve PA, including the provision of adequate nutrients for crops and the wastage of pesticides for the effective control of weeds, pests, and diseases. This review outlines the recent applications of WSNs in agriculture research as well as classifies and compares various wireless communication protocols, the taxonomy of energy-efficient and energy harvesting techniques for WSNs that can be used in agricultural monitoring systems, and comparison between early research works on agriculture-based WSNs. The challenges and limitations of WSNs in the agricultural domain are explored, and several power reduction and agricultural management techniques for long-term monitoring are highlighted. These approaches may also increase the number of opportunities for processing Internet of Things (IoT) data.

Published: August 2017

Exhaled breath is a body secretion, and the sampling process of this is simple and cost effective. It can be non-invasively collected for diagnostic procedures. Variations in the chemical composition of exhaled breath resulting from gaseous exchange in the extensive capillary network of the body are proposed to be associated with pathophysiological changes. In light of the foreseeable potential of exhaled breath as a diagnostic specimen, we used gas chromatography and mass spectrometry (GC-MS) to study the chemical compounds present in exhaled breath samples from patients with Alzheimer’s disease (AD), Parkinson’s disease (PD), and from healthy individuals as a control group. In addition, we also designed and developed a chemical-based exhaled breath sensor system to examine the distribution pattern in the patient and control groups. The results of our study showed that several chemical compounds, such as 1-phenantherol and ethyl 3-cyano-2,3-bis (2,5,-dimethyl-3-thienyl)-acrylate, had a higher percentage area in the AD group than in the PD and control groups. These results may indicate an association of these chemical components in exhaled breath with the progression of disease. In addition, in-house fabricated exhaled breath sensor systems, containing several types of gas sensors, showed significant differences in terms of the normalized response of the sensitivity characteristics between the patient and control groups. A subsequent clustering analysis was able to distinguish between the AD patients, PD patients, and healthy individuals using principal component analysis, Sammon’s mapping, and a combination of both methods, in particular when using the exhaled breath sensor array system A consisting of eight sensors. With this in mind, the exhaled breath sensor system could provide alternative option for diagnosis and be applied as a useful, effective tool for the screening and diagnosis of AD in the near future.
Monocular Vision-Based Underwater Object Detection

Published: August 2017

In this paper, we propose an underwater object detection method using monocular vision sensors. In addition to commonly used visual features such as color and intensity, we investigate the potential of underwater object detection using light transmission information. The global contrast of various features is used to initially identify the region of interest (ROI), which is then filtered by the image segmentation method, producing the final underwater object detection results. We test the performance of our method with diverse underwater datasets. Samples of the datasets are acquired by a monocular camera with different qualities (such as resolution and focal length) and setups (viewing distance, viewing angle, and optical environment). It is demonstrated that our ROI detection method is necessary and can largely remove the background noise and significantly increase the accuracy of our underwater object detection method.
Constrained Active Learning for Anchor Link Prediction Across Multiple Heterogeneous Social Networks
Authors: Zhu Junxing , Zhang Jiawei , Wu Quanyuan , Jia Yan , Zhou Bin , Wei Xiaokai , Yu Philip
Published: August 2017

Nowadays, people are usually involved in multiple heterogeneous social networks simultaneously. Discovering the anchor links between the accounts owned by the same users across different social networks is crucial for many important inter-network applications, e.g., cross-network link transfer and cross-network recommendation. Many different supervised models have been proposed to predict anchor links so far, but they are effective only when the labeled anchor links are abundant. However, in real scenarios, such a requirement can hardly be met and most anchor links are unlabeled, since manually labeling the inter-network anchor links is quite costly and tedious. To overcome such a problem and utilize the numerous unlabeled anchor links in model building, in this paper, we introduce the active learning based anchor link prediction problem. Different from the traditional active learning problems, due to the one-to-one constraint on anchor links, if an unlabeled anchor link a = ( u , v ) is identified as positive (i.e., existing), all the other unlabeled anchor links incident to account u or account v will be negative (i.e., non-existing) automatically. Viewed in such a perspective, asking for the labels of potential positive anchor links in the unlabeled set will be rewarding in the active anchor link prediction problem. Various novel anchor link information gain measures are defined in this paper, based on which several constraint active anchor link prediction methods are introduced. Extensive experiments have been done on real-world social network datasets to compare the performance of these methods with state-of-art anchor link prediction methods. The experimental results show that the proposed Mean-entropy-based Constrained Active Learning (MC) method can outperform other methods with significant advantages.

This paper explores the current trajectory of multilateral governance for climate change adaptation in S. Korea, which is characterised by vertical and horizontal adaptation governance. This article highlights that the characteristics of adaptation governance can be realised more effectively through grassroot activities at both metropolitan and local government levels. In particular, a thorough examination on the implemented adaptation measures (‘national climate change adaptation scheme’, ‘national climate change adaptation centre’, and the climate change ‘Ansim Village’ project) as well as the limitations at the national and local level were carried out. Ultimately, as a result, this paper suggests of the effective multilateral governance for climate change adaptation; enhancing the multilateral partnership between the national government and local governments, facilitating horizontal governance within the adaptation departments of local governments, managing adaptation horizontal governance by sectors according to the characteristics of climate change risk, and establishing sustainable adaptation governance for ‘Ansim’ Village.
Projecting the CO2 and Climatic Change Effects on the Net Primary Productivity of the Urban Ecosystems in Phoenix, AZ in the 21st Century under Multiple RCP (Representative Concentration Pathway) Scenarios
Authors: Chen Chunbo , Zhang Chi
Published: August 2017

Urban vegetation provides ecological services that promote both the ecosystem integrity and human well-being of urban areas, and thus is critical to urban sustainability. As a key indicator of ecological health, net primary productivity (NPP) provides valuable information about the performance of urban ecosystem in response to the changes in urban climate and atmosphere in the 21st century. In this study, a process-based urban ecosystem model, HPM-UEM (Hierarchical Patch Mosaic-Urban Ecosystem Model), was used to investigate spatiotemporal dynamics of urban ecosystem NPP in the Phoenix city, AZ under three representative concentration pathway (RCP2.6, RCP4.5 and RCP8.5) during the 21st century. The results indicated that, by the end of the 21st century, the urban ecosystem’s NPP would increase by 14% (in RCP2.6), 51% (in RCP4.5) and 99% (in RCP8.5) relative to that in the late 2000s, respectively. Factorial analysis indicated that CO2 fertilization effect would be the major driver of NPP change, accounting for 56–61% of the NPP increase under the scenarios. Under the RCP2.6 scenario, the strongest NPP increase would be found in the agricultural lands located in the west and southeast of the city. Under the RCP4.5 and RCP8.5 scenarios, the strongest NPP increase would be found in the mesic residential areas that mainly located to the eastern, southern, and southwestern of the Phoenix Mountains Preserve. Although higher ecosystem NPP in the future implies improved ecosystem services that may help to alleviate the heat stress (by providing more shading) and air pollution in the city, this will be at the cost of higher irrigation water usage, probably leading to water shortage in the natural ecosystems in this arid region. Furthermore, this study indicated the rich (such as in mesic residential area) would enjoy more benefits from the improved urban ecosystem services than the poor (such as in xeric residential area).
Applying the Concept of Perceived Restoration to the Case of Cheonggyecheon Stream Park in Seoul, Korea
Authors: Kim Moohan , Gim Tae-Hyoung , Sung Jong-Sang
Published: August 2017

Studies on perceived restoration have focused on the differences between natural and artificial environments, whereas studies on what makes people select a particular restorative environment are limited. Using the location of Cheonggyecheon Stream Park in the urban center of Seoul, South Korea, this study tests whether people self-select locations based on individual and environmental characteristics. Empirical testing was conducted on 268 responses on a visitor survey that was developed based on the Perceived Restorativeness Scale. The major findings were that visitors’ characteristics such as gender, age, number of companions, visit frequency, and travel mode affect their selection of a particular setting, and that the chosen setting subsequently influences three dimensions of the Scale: being away, fascination, and coherence. These findings suggest that both individual and environmental characteristics should be considered in the creation of an effective perceived restorative environment in an urban center.
A Spatial-Territorial Reorganization Model of Rural Settlements Based on Graph Theory and Genetic Optimization
Authors: Mao Yan , Liu Yanfang , Wang Haofeng , Tang Wei , Kong Xuesong
Published: August 2017

Rural China has experienced rapid urbanization and industrialization, accompanied with rural–urban migration since 1978. This tremendous transition has caused a series of negative consequences, necessitating a spatial-territorial reorganization of rural settlements. Previous studies on the restructuring of rural settlements are insufficient for inter-settlement connection consideration and practical and dynamic decision-making techniques. To overcome these concerns, a dynamic spatial-territorial reorganization model (SRM) of rural settlement is proposed herein based on graph theory and genetic algorithm (GA). The model involves two parts. In Part 1, consolidated settlements are identified according to the socio-economic network performance under four types of attack. In Part 2, GA model is repeatedly executed to scientifically resettle consolidated settlements into nearby townships or central settlements with objectives of suitability, compactness, and local connectivity under the control of the constraints. This paper presents an application of SRM to Chengui Town, Hubei Province. Empirical results suggest that: (1) removing settlements in order of node degree is the least efficient way to destroy the entire functional system; and (2) the proposed model can yield satisfactory solutions in terms of spatial reorganization of settlements. The SRM may also serve as a valuable reference for planners in devising plans and making decisions.

Recently, the integrated landscape approach has gained increasing interest of the scientific community, as well as of organizations active in the field of sustainable development. However, the enthusiastic welcome is challenged by little consensus on theory, terminology and definitions. Moreover, the operationalization of the approach into practice is a major challenge. In this paper, we present a framework to operationalize the integrated landscape approach in practice by putting a long-term collaboration between scientists and various stakeholder at center stage. Based on encompassing understanding of landscape-level processes and interactions, four pillars addressing different steps of a joint-learning circle are described and illustrated with examples. We consider the integrated landscape approach to be a prime way of targeting the Sustainable Development Goals (SDGs), but novel forms of collaboration between scientists and other stakeholders based on long-term commitments will be needed for operationalization in practice.

Introduction: The burden of care in family refers to the weight caused by the primary caregiver role to psychiatric patients and the difficulties encountered in performing this function in daily life.

Objectives: Assessing the objective and subjective overload of family members who live with the reality of psychiatric disorder in a child day-care psychosocial care center. Methods: Cross-sectional study, descriptive-exploratory, of quantitative approach, with non-probabilistic samples of accidental type with 80 families of psychiatric patients held in a Psychosocial Care Center. For overload evaluation, the subscales "B" and "D" of the Family Overload Rating Scale (FBIS-BR) were used.

Results: The study was conducted with 80 families of psychiatric patients. The average age of female caregivers was 39,6 years old, and 40,7 years old for male caregivers, with female predominance (87,5%) compared to men (12,5%), with low education for both genres. Family caregivers presented high objective burden due to excessive demand attention (p<0,001), heteroaggressiveness (p<0,001) and perplexing behavior of psychiatric patients regarding the supervision of problematic behaviors (p<0,001). The items on the impact on the family's daily routine have not helped to generate objective overload for the family members. On subjective overload, it was clear to observe familiar members with high degree of disturbance in all the dimensions assessed (p < 0,001).

Conclusion: The high degree of care overload observed in family members indicates the need to develop contacts with the family of the psychiatric patient to answer questions, offer support and assistance to the family caregiver.

Navettes domicile-travail : naissance et développement d’un objet statistique structurant
Authors: Commenges Hadrien , Fen-Chong Julie
Published: August 2017

Ce travail s’applique à retracer l’histoire des « navettes » ou « migrations alternantes » en tant qu’objet statistique. Nous partons du constat que l’objet navette, depuis sa naissance dans les années 1930, a pris une importance grandissante dans les études de géographie urbaine et de mobilité quotidienne. Alors que cet objet a très peu évolué dans son mode de production, son domaine de validité s’est considérablement étendu. Sur la base de ce constat, nous cherchons à comprendre les raisons de la montée en importance de cet objet statistique et nous analysons les constructions empiriques et théoriques sur lesquelles s’appuie l’extension de son domaine de validité. Nous faisons l’hypothèse que ces constructions ont façonné une certaine vision du territoire et de mobilité que nous qualifions de « salariale ». La navette est devenue au cours du XX e  siècle l’objet qui traduit la structuration de l’espace, qui participe à la définition de son urbanité, qui résume les pratiques de mobilité et dessine les espaces de vie. A sa création, elle n’était pourtant destinée à aucune de ces tâches. Comment l’objet navette, dont le pouvoir descriptif et explicatif de la structuration de l’espace et de la mobilité quotidienne est apparemment limité, en est arrivé à occuper une situation de quasi-monopole en cette matière ?
De la « gestion » au contrôle des migrations ? Discours et pratiques de l’Organisation internationale pour les migrations
Authors: Pécoud Antoine
Published: August 2017

L’Organisation internationale pour les migrations (OIM) est une organisation peu étudiée dont le mandat concerne pourtant l’un des enjeux les plus politisés des pays occidentaux aujourd’hui. La présentation ici de l’histoire, de la doctrine et des pratiques de l’OIM montre qu’elle a été longtemps une organisation fragile, dans un contexte où les politiques migratoires ne faisaient pas l’objet d’un régime international solide, mais qu’elle s’est imposée, depuis les années 1990, comme un acteur incontournable de la mondialisation et de l’externalisation des politiques migratoires. Sa stratégie consiste à dépolitiser les enjeux migratoires et à promouvoir une gestion technique des migrations, centrée sur leur utilité économique pour toutes les parties (pays d’origine, pays de de destination et migrants). Cela lui permet d’apparaître comme un intermédiaire neutre, accepté aussi bien par les États que par les acteurs de la société civile et du secteur privé. Cependant, cette dépolitisation s’accompagne d’un alignement de l’OIM sur les intérêts des pays d’immigration occidentaux, et rend donc possible des interventions hautement politiques, en particulier dans les pays d’origine des migrants.
Transferts et continuités de la politisation à l’Organisation mondiale de la santé : le cas des substituts du lait maternel
Authors: Guilbaud Auriane
Published: August 2017

L’analyse des débats relatifs à l’alimentation des nourrissons par des substituts du lait maternel qui se sont tenus au sein de l’Organisation mondiale de la santé dès la fin des années 1960 permet de revenir sur les stratégies et techniques de (dé)politisation mobilisées par les ONG, les entreprises, les États, les bureaucraties des OI dans et autour de l’arène des organisations internationales. Les notions de politisation et dépolitisation sont utilisées ici dans le but d’éclairer le fonctionnement de l’OMS, au-delà de son caractère « technique » très souvent supposé, et de mettre en évidence les investissements dont elle fait l’objet, en particulier de la part d’acteurs non étatiques. Les trois stratégies identifiées – provoquer le conflit versus rechercher le consensus, aspirer à la publicisation versus au confinement, avoir recours à des principes idéologiques versus prôner une approche pragmatique – sont mises en œuvre par différentes techniques (recours à des représentants politiques, à des experts, à des arguments scientifiques ou techniques, à des médias) et de manière différenciée selon les types d’acteurs. Moment structurant pour l’OMS, la question des substituts du lait maternel a suscité des effets d’entraînement de la politisation, désormais permanente avec un élargissement sectoriel à de nouvelles thématiques.
Traditions comportementales et capitalisme dynastique. Le cas des « grandes familles »
Authors: Hau Michel
Published: August 2017

Au sommet de la bourgeoisie se trouvent les « grandes familles ». Elles se distinguent non seulement par leur richesse pécuniaire, mais encore par le grand nombre de leurs membres parvenus à un certain prestige social. L’étude d’un échantillon représentatif des plus anciennes d’entre elles révèle qu’elles appartiennent généralement au monde germanique, que leur structure est celle de la famille souche, qu’elles ont pour origine le patriciat de petites villes libres de l’Europe médiévale, et qu’elles sont de confession protestante ou juive. Leur réussite repose sur la transmission, par l’éducation, d’un capital comportemental doté d’une grande utilité adaptative dans une ère de progrès technique rapide.
Echec industriel et réussite sociale, le cas du capitalisme familial marseillais. L’industrie marseillaise des corps gras à travers la trajectoire sociale d’un groupe familial de la bourgeoisie
Authors: Zalio Pierre-Paul
Published: August 2017

La disparition des industries traditionnelles de Marseille est le plus souvent imputée à la crise du port et aux caractéristiques d’un patronat plus spéculateur qu’industriel. Sans rejeter ces explications, l’étude d’une entreprise oléagineuse, l’Huilerie Nouvelle, permet de préciser les liens entre le port comme espace économique et l’entreprise comme entité familiale. Au rôle fondateur joué par la cohésion du groupe familial succède une phase de diversification des alliances qui accompagne la croissance. Ce maillage familial des petites entreprises, redoublé par des investissements sociaux, assure cohérence et efficacité à cette industrie centrée sur la Bourse des matières premières. La concentration de la majeure partie de ces entreprises à la fin des années 1950, au sein de l’Union industrielle des produits oléagineux (Unipol), permet d’analyser une réponse à la concurrence des grands groupes du secteur qui articule regroupement de la production et respect des équilibres familiaux. Mais cette tentative ne permit pas de sauver ce qui fat une des industries symboles de la ville.

L’explosion intervenue en janvier 1966 à la raffinerie de Feyzin, au sud de Lyon, se situe dans un contexte d’expansion pétrolière et aux débuts de l’histoire d’un nouveau groupe pétrolier national (l’ERAP). Ce fait tragique (18 victimes) souligne la multiplicité des responsabilités face à la complexité des techniques modernes. Tout jugement devient délicat en conséquence, balançant entre la fatalité cruelle et le choix de quelques responsables facilement identifiables.

Published: August 2017

Cet article propose d’explorer le mouvement respiratoire comme métaphore du processus d’individuation-séparation à l’adolescence. Nous verrons comment l’attention portée sur la respiration en Eutonie peut devenir une médiation au sein d’une thérapie psychomotrice. Nous aborderons la question de la quête identitaire impliquant un processus de perte. Comment aménager un espace d’élaboration tout en éprouvant les douloureuses transformations vécues dans le corps ? Peut-on se transformer sans prendre le risque de perdre ou de lâcher quelque chose ? Par l’intermédiaire de vignettes cliniques, nous détaillerons comment jouer de cette expressivité du dedans (tonicité, respiration, images mentales…), permettant à l’adolescent de se saisir de son propre processus de changement.

El movimiento de los indignados en España coincidió con el auge de la emigración juvenil española debido a la crisis. En este artículo se analizará el caso de Londres, donde la comunidad española creó un movimiento que les permitiera unirse a la lucha iniciada en España: el 15-M Londres, el cual se convirtió en Marea Granate Londres para poder dar cabida a más gente emigrada a la capital británica. A partir del análisis del movimiento pretendemos debatir su naturaleza: ¿es transnacional o es una expresión en el exterior de un movimiento puramente nacional?.
Redefiniendo las identidades waria en la Indonesia contemporánea
Authors: Nuño Martínez Néstor
Published: August 2017

El análisis de identidades de género no hegemónicas en el Sur Global ha propiciado un replanteamiento de los enfoques y paradigmas tradicionales. Hoy en día, el constante flujo a nivel global de imágenes y generalidades en torno a la belleza y el sexo se mezcla e interactúa junto a la diseminación de ideologías de corte individualista, concibiendo constructos de género de gran variabilidad, permeabilidad y porosidad. Este artículo busca discutir los modelos clásicos empleados para conceptualizar a las waria (travestís femeninos) de Indonesia y a su vez repensar la construcción del término a partir de un análisis de los recientes cambios acontecidos en el país. Dicho replanteamiento está ligado a la necesidad de acuñar enfoques alternativos que aborden la mutabilidad de las realidades de género en un mundo cada vez más globalizado.
La función social e ideológica de las fiestas religiosas: identidad local, control social e instrumento de dominación
Authors: Domene Verdú José Fernando
Published: August 2017

El presente artículo intenta responder a la pregunta: ¿qué función tienen las fiestas religiosas y patronales en la sociedad, ahora y a lo largo de la Historia? Pertenecen a lo que se denomina religiosidad popular, son utilitaristas, porque se utilizaban como solución a las calamidades naturales y sanitarias, y son principalmente un símbolo de identidad local o regional. Pero, además, han tenido siempre una función social, que se podría resumir en el mantenimiento del orden social establecido mediante la identificación de parte de la población con la aristocracia dominante. El paralelismo entre Dios, la Virgen y los santos con los reyes, los señores feudales y los miembros de la nobleza en general favorecía que las mismas actitudes de obediencia y sumisión que el pueblo tenía hacia los personajes religiosos las tuviera también hacia los personajes de la sociedad feudal, la nobleza, el clero y la posterior monarquía absoluta. Las fiestas religiosas (Semana Santa, Navidad, Reyes Magos y, sobre todo, las fiestas patronales) eran, entonces, la manifestación cultural más idónea para propiciar que el pueblo llano adoptara estas actitudes hacia unos e, indirectamente, también hacia los otros.
El juego motor del marro: una indagación acerca de sus raíces pedagógicas
Authors: Brasó Rius Jordi , Torrebadella Flix Xavier

Desde muy antiguo el juego motor del marro ha permanecido en el depósito cultural de la civilización occidental. Sin embargo, las raíces antropológicas, sociológicas y pedagógicas de este juego han sido escasamente investigadas. A partir de la indagación cultural de sus orígenes nos adentramos en averiguar el por qué esta práctica físico-recreativa ha permanecido durante tantos siglos prácticamente inalterada. El estudio parte de un enfoque histórico-genealógico y fenomenológico interdisciplinar (antropología, sociología y pedagogía) sustentado por una variada revisión documental de fuentes primarias. Los resultados nos llevan a sostener que en la lógica interna del juego del marro subyacen los códigos socializantes de la pedagogía contemporánea, por lo que su duradera presencia viene a garantizar la teoría del «proceso de civilización» de Occidente. Esta interpretación contribuye también a valorar una comprensión fenomenológica en la historia de los juegos corporales y el rol que desempeñan en la sociedad.

Learner modeling is a crucial step in the learning personalization process. It allows taking into consideration the learner's profile to make the learning process more efficient. Most studies refer to an explicit method, namely questionnaire, to model learners. Questionnaires are time consuming and may not be motivating for learners. Thus, this paper presents a new approach for Modeling the learner's Personality, introvert/extrovert, using Educational Games (MoPEG). The proposed approach includes three phases, namely design of the educational game, collection of traces and personality prediction. To evaluate the efficiency of MoPEG, an experiment was conducted with thirty learners where their personality modeling results using MoPEG are compared to the Big Five Inventory (BFI) questionnaire. The obtained results showed that the accuracy level of MoPEG is significant with an 80% of similarity. Besides, based on the Kappa method, used by psychologists to measure the similarity of two instruments. The obtained results highlighted an agreement degree of MoPEG with the level “good”.

This study examined pre-service teachers' expertise, perceptions and integration of cloud applications in teaching of Arabic and English. Questionnaires and semi-structured interviews were used as data collection methods. The findings of the study specified that pre-service teachers did not own sufficient expertise for effective integration of cloud applications. The findings also revealed that participants perceived cloud applications as a valuable tool to improve many aspects of language education. Nonetheless, participants concentrated on integrating limited features of cloud applications. While the study revealed that there was no significant difference in participants' expertise in integrating cloud applications based on the language they teach, it found that pre-service English teachers had significantly higher levels of positive perceptions and integration of cloud applications than pre-service Arabic teachers. Finally, a positive significant correlation was found between expertise, perceptions, and integration of cloud applications.

The purpose of this study was to compare the influence of a single-player game with that of a collaborative game on students' motivation, attention levels, and relaxation levels in a motion-sensing learning environment. Participants were 20 college students in a higher education institution in southern Taiwan. A Kinect-based game with motion-sensing technology was incorporated to help the students enhance their attention levels and reduce their anxiety. Results showed that when the students worked collaboratively, they achieved higher learning motivation. In addition, brainwave data revealed that during the gaming activities, the students' attention levels in both conditions increased. It is suggested that instructors can incorporate collaborative learning environments with a Kinect motion-sensing platform to enhance students' learning motivation.

Published: August 2017

The following paper describes a collaborative service-learning project done in an online graduate class on instructional design. With the help of the university's service-learning program, a community issue was identified related to encouraging underserved populations to pursue STEM careers. Graduate students developed a data analysis from surveying high school students, designed and implemented a website where information about specific careers can be found, and evaluated the project with the help of a high school science teacher. The project also required that the graduate students reflected about the service activity to gain a deeper understanding of course objectives. The course instructor and graduate students' experiences during this service-learning project are discussed.

This study evaluated the nutritional characteristics of hay of nineteen hybrids between sorghum and Sudan grass. The experimental design was a randomized block with nineteen treatments and three replications. The chemical characteristics of the respective hays were analyzed 52 days after sowing and 45 and 49 regrowth days. Data were analyzed by analysis of variance, and when the F test was significant, the treatment means were compared by the Scott and Knott test at 5%. Genotypes 1013026 and 1014020 showed similar dry matter content. As for ether extract content, the highest values ranged from 2.20 to 2.66%. Higher values of minerals were observed in hybrids 1013026 and 1011005. In relation to crude protein, higher content values were reported for hybrids 1013021 and 1013020 (14.59 and 15.47% CP). When evaluating the neutral detergent fiber content, lower values varied between 56.05 and 57.07% for hybrids 1013016 and 1011009. Considering the content of acid detergent fiber, values ranged from 32.70 to 35.78%. Values of dry matter digestibility were higher than 50%. All hybrids provide quality hay, however the hybrid 1014019 showed the best nutritional value.

This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 160 Dekalb White hens with 52-wk old were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost.

Experimental CMV-based vaccine vectors expressing a single MHC class I–restricted high-avidity epitope provided strong, T cell–dependent protection against viruses or tumors. In this study we tested the low-avidity epitope KCSRNRQYL, and show that a mouse CMV (MCMV) vector provides complete immune control of recombinant vaccinia virus expressing the same epitope if KCSRNRQYL is expressed within the immediate-early MCMV gene ie2. The same epitope expressed within the early M45 gene provided no protection, although MCMV vectors expressing the high-avidity epitope SSIEFARL induced protective immunity irrespective of gene expression context. Immune protection was matched by Ag-induced, long-term expansion of effector memory CD8 T cells, regardless of epitope avidity. We explained this pattern by observing regularities in Ag competition, where responses to high-avidity epitopes outcompeted weaker ones expressed later in the replicative cycle of the virus. Conversely, robust and early expression of a low-avidity epitope compensated its weak intrinsic antigenicity, resulting in strong and sustained immunity and immune protection.
