Published: June 2016

Abstract. Soil moisture is important to enable the growth of vegetation in the way that it also conditions the development of plant population. Additionally, its assessment is important in hydrology and agronomy, and is a warning parameter for desertification. Furthermore, the soil moisture content affects exchanges with the atmosphere via the energy balance at the soil surface; it is significant due to its impact on soil evaporation and transpiration. Therefore, it conditions the energy transfer between Earth and atmosphere. Many remote sensing methods were tested. For the soil moisture; the first methods relied on the optical domain (short wavelengths). Obviously, due to atmospheric effects and the presence of clouds and vegetation cover, this approach is doomed to fail in most cases. Therefore, the presence of vegetation canopy complicates the retrieval of soil moisture because the canopy contains moisture of its own. This paper presents a synergistic methodology of SAR and optical remote sensing data, and it’s for simulation of statistical parameters of soil from C-band radar measurements. Vegetation coverage, which can be easily estimated from optical data, was combined in the backscattering model. The total backscattering was divided into the amount attributed to areas covered with vegetation and that attributed to areas of bare soil. Backscattering coefficients were simulated using the established backscattering model. A two-dimensional multiscale SPM model has been employed to investigate the problem of electromagnetic scattering from an underlying soil. The water cloud model (WCM) is used to account for the effect of vegetation water content on radar backscatter data, whereof to eliminate the impact of vegetation layer and isolate the contributions of vegetation scattering and absorption from the total backscattering coefficient.
A METHOD OF GENERATING PANORAMIC STREET STRIP IMAGE MAP WITH MOBILE MAPPING SYSTEM
Authors: Tianen Chen , Yamamoto Kohei , Tachibana Kikuo
Published: June 2016

Abstract. This paper explores a method of generating panoramic street strip image map which is called as “Pano-Street” here and contains both sides, ground surface and overhead part of a street with a sequence of 360° panoramic images captured with Point Grey’s Ladybug3 mounted on the top of Mitsubishi MMS-X 220 at 2m intervals along the streets in urban environment. On-board GPS/IMU, speedometer and post sequence image analysis technology such as bundle adjustment provided much more accuracy level position and attitude data for these panoramic images, and laser data. The principle for generating panoramic street strip image map is similar to that of the traditional aero ortho-images. A special 3D DEM(3D-Mesh called here) was firstly generated with laser data, the depth map generated from dense image matching with the sequence of 360° panoramic images, or the existing GIS spatial data along the MMS trajectory, then all 360° panoramic images were projected and stitched on the 3D-Mesh with the position and attitude data. This makes it possible to make large scale panoramic street strip image maps for most types of cities, and provides another kind of street view way to view the 360° scene along the street by avoiding the switch of image bubbles like Google Street View and Bing Maps Streetside.
THE PERFORMANCE OF A TIGHT INS/GNSS/PHOTOGRAMMETRIC INTEGRATION SCHEME FOR LAND BASED MMS APPLICATIONS IN GNSS DENIED ENVIRONMENTS
Authors: Chu Chien-Hsun , Chiang Kai-Wei
Published: June 2016

Abstract. The early development of mobile mapping system (MMS) was restricted to applications that permitted the determination of the elements of exterior orientation from existing ground control. Mobile mapping refers to a means of collecting geospatial data using mapping sensors that are mounted on a mobile platform. Research works concerning mobile mapping dates back to the late 1980s. This process is mainly driven by the need for highway infrastructure mapping and transportation corridor inventories. In the early nineties, advances in satellite and inertial technology made it possible to think about mobile mapping in a different way. Instead of using ground control points as references for orienting the images in space, the trajectory and attitude of the imager platform could now be determined directly. Cameras, along with navigation and positioning sensors are integrated and mounted on a land vehicle for mapping purposes. Objects of interest can be directly measured and mapped from images that have been georeferenced using navigation and positioning sensors. Direct georeferencing (DG) is the determination of time-variable position and orientation parameters for a mobile digital imager. The most common technologies used for this purpose today are satellite positioning using the Global Navigation Satellite System (GNSS) and inertial navigation using an Inertial Measuring Unit (IMU). Although either technology used along could in principle determine both position and orientation, they are usually integrated in such a way that the IMU is the main orientation sensor, while the GNSS receiver is the main position sensor. However, GNSS signals are obstructed due to limited number of visible satellites in GNSS denied environments such as urban canyon, foliage, tunnel and indoor that cause the GNSS gap or interfered by reflected signals that cause abnormal measurement residuals thus deteriorates the positioning accuracy in GNSS denied environments. This study aims at developing a novel method that uses ground control points to maintain the positioning accuracy of the MMS in GNSS denied environments. At last, this study analyses the performance of proposed method using about 20 check-points through DG process.
3D FEATURE POINT EXTRACTION FROM LIDAR DATA USING A NEURAL NETWORK
Authors: Feng Y. , Schlichting A. , Brenner C.
Published: June 2016

Abstract. Accurate positioning of vehicles plays an important role in autonomous driving. In our previous research on landmark-based positioning, poles were extracted both from reference data and online sensor data, which were then matched to improve the positioning accuracy of the vehicles. However, there are environments which contain only a limited number of poles. 3D feature points are one of the proper alternatives to be used as landmarks. They can be assumed to be present in the environment, independent of certain object classes. To match the LiDAR data online to another LiDAR derived reference dataset, the extraction of 3D feature points is an essential step. In this paper, we address the problem of 3D feature point extraction from LiDAR datasets. Instead of hand-crafting a 3D feature point extractor, we propose to train it using a neural network. In this approach, a set of candidates for the 3D feature points is firstly detected by the Shi-Tomasi corner detector on the range images of the LiDAR point cloud. Using a back propagation algorithm for the training, the artificial neural network is capable of predicting feature points from these corner candidates. The training considers not only the shape of each corner candidate on 2D range images, but also their 3D features such as the curvature value and surface normal value in z axis, which are calculated directly based on the LiDAR point cloud. Subsequently the extracted feature points on the 2D range images are retrieved in the 3D scene. The 3D feature points extracted by this approach are generally distinctive in the 3D space. Our test shows that the proposed method is capable of providing a sufficient number of repeatable 3D feature points for the matching task. The feature points extracted by this approach have great potential to be used as landmarks for a better localization of vehicles.
EVALUATION OF DRIVER VISIBILITY FROM MOBILE LIDAR DATA AND WEATHER CONDITIONS
Authors: González-Jorge H. , Díaz-Vilariño L. , Lorenzo H. , Arias P.
Published: June 2016

Abstract. Visibility of drivers is crucial to ensure road safety. Visibility is influenced by two main factors, the geometry of the road and the weather present therein. The present work depicts an approach for automatic visibility evaluation using mobile LiDAR data and climate information provided from weather stations located in the neighbourhood of the road. The methodology is based on a ray-tracing algorithm to detect occlusions from point clouds with the purpose of identifying the visibility area from each driver position. The resulting data are normalized with the climate information to provide a polyline with an accurate area of visibility. Visibility ranges from 25 m (heavy fog) to more than 10,000 m (clean atmosphere). Values over 250 m are not taken into account for road safety purposes, since this value corresponds to the maximum braking distance of a vehicle. Two case studies are evaluated an urban road in the city of Vigo (Spain) and an inter-urban road between the city of Ourense and the village of Castro Caldelas (Spain). In both cases, data from the Galician Weather Agency (Meteogalicia) are used. The algorithm shows promising results allowing the detection of particularly dangerous areas from the viewpoint of driver visibility. The mountain road between Ourense and Castro Caldelas, with great presence of slopes and sharp curves, shows special interest for this type of application. In this case, poor visibility can especially contribute to the run over of pedestrians or cyclists traveling on the road shoulders.
ACCURACY ASSESSMENT OF MOBILE MAPPING POINT CLOUDS USING THE EXISTING ENVIRONMENT AS TERRESTRIAL REFERENCE
Authors: Hofmann S. , Brenner C.
Published: June 2016

Abstract. Mobile mapping data is widely used in various applications, what makes it especially important for data users to get a statistically verified quality statement on the geometric accuracy of the acquired point clouds or its processed products. The accuracy of point clouds can be divided into an absolute and a relative quality, where the absolute quality describes the position of the point cloud in a world coordinate system such as WGS84 or UTM, whereas the relative accuracy describes the accuracy within the point cloud itself. Furthermore, the quality of processed products such as segmented features depends on the global accuracy of the point cloud but mainly on the quality of the processing steps. Several data sources with different characteristics and quality can be thought of as potential reference data, such as cadastral maps, orthophoto, artificial control objects or terrestrial surveys using a total station. In this work a test field in a selected residential area was acquired as reference data in a terrestrial survey using a total station. In order to reach high accuracy the stationing of the total station was based on a newly made geodetic network with a local accuracy of less than 3 mm. The global position of the network was determined using a long time GNSS survey reaching an accuracy of 8 mm. Based on this geodetic network a 3D test field with facades and street profiles was measured with a total station, each point with a two-dimensional position and altitude. In addition, the surface of poles of street lights, traffic signs and trees was acquired using the scanning mode of the total station. Comparing this reference data to the acquired mobile mapping point clouds of several measurement campaigns a detailed quality statement on the accuracy of the point cloud data is made. Additionally, the advantages and disadvantages of the described reference data source concerning availability, cost, accuracy and applicability are discussed.
Analysing post-earthquake landslide activity using multi-temporal landslide inventories near the epicentral area of the 2008 Wenchuan earthquake
Authors: Tang Chenxiao , Van Westen Cees J. , Tanyaş Hakan , Jetten Victor G.
Published: June 2016

Abstract. Large earthquakes in mountainous regions may trigger thousands of landslides, some active for years. We analysed the changes in landslide activity near 2008 Wenchuan earthquake epicentre, generating five landslide inventories for different years through stereoscopic digital visual image interpretation. From May 2008 to April 2015, 660 new landslides occurred outside the co-seismic landslide areas. In April 2015, the number of active landslides had gone down to 66, less than 1 % of the co-seismic landslides, still much higher than the pre-earthquake situation. We expect that the landslide activity will continue to decay, but may be halted if extreme rainfall events occur.
Control Spectra for Quito
Authors: Aguiar Roberto , Rivas-Medina Alicia , Caiza Pablo , Quizanga Diego
Published: June 2016

Abstract. The Metropolitan District of Quito is divided into five areas: south, south-central, central, north-central and north. It is located on or very close to segments of reverse blind faults: Puengasí, Ilumbisí-La Bota, Carcelen-El Inca, Bellavista-Catequilla and Tangahuilla as indicated in Alvarado et al. (2014), making it one of the most seismically dangerous cities in the world. For each of the urban areas of Quito, elastic response spectra are presented in this paper, which are found using some of the new models of the PEER's NGA-West2 Program, models developed by: Abrahamson et al. (2013), Campbell and Borzognia (2013), and Chiou and Youngs (2013). These spectra are calculated considering the maximum amount that could be generated by the rupture of each fault segments, and taking into account the soil type that exists in each zone according to the Norma Ecuatoriana de la Construcción 2015 (NEC-15). Subsequently, the recurrence period of earthquakes of high magnitude in each fault segment is determined from the physical parameters of the fault segments (size of the fault plane and slip rate), and considering that the fault can break in earthquakes of magnitude less than the expected maximum (minimum size 5.0 Mw). For this, the pattern of recurrence of type GR earthquakes (Gutenberg and Richter, 1944) with double truncation magnitude (Mmin and Mmax) proposed by Cosentino et al. (1977) is used.
« "Le gênant", c‟est qu‟Olivier ne sera pas seul ». Le problème de l‟adjectif substantivé thématisé en français
Authors: Bidaud Samuel
Published: June 2016

Nous étudions dans cet article les tournures du type « Le gênant, c’est qu’Olivier ne sera pas seul », lesquelles sont fréquemment décrites, d’un point de vue formel, comme des structures de type article/adjectif substantivé. Après avoir analysé les propriétés morphosyntaxiques de notre tournure, nous montrons qu’en réalité on ne saurait parler d’adjectif substantivé par un article, dans la mesure où ni l’adjectif ne devient un substantif, ni l’article ne fonctionne comme un véritable article. Ce dernier, en effet, peut être défini comme un « article-démonstratif neutre ». Nous sommes dans cette perspective amené à repenser le schéma de l’article de la psychomécanique du langage, et à proposer du tenseur binaire guillaumien une vision élargie que l’on peut représenter par un schème trimorphe.
Le pèlerinage intertextuel de Compostelle dans les récits francophones de voyages en Espagne au XIXe siècle
Authors: Iñarrea Las Heras Ignacio
Published: June 2016

Le pèlerinage de Compostelle se trouvait au XIXe siècle dans une situation de décadence. En fait, et en ce qui concerne les pèlerins provenant de la France, il faut dire que leur nombre diminua énormément. De la même manière, il n’y a pas beaucoup de récits de voyages en Espagne à cette époque, écrits en français, dont les auteurs aient montré un certain intérêt pour ce phénomène religieux. L’étude de ces ouvrages a permis de constater que le culte de saint Jacques était considéré par ces voyageurs écrivains comme une sorte de vestige historique prestigieux. Ils accordent très peu de place à la description de sa situation réelle à ce moment-là. C’est pour cela qu’ils utilisèrent surtout des sources documentaires pour en parler dans leurs propres textes. Par conséquent, leur connaissance de cet univers est surtout indirecte, intertextuelle.
Ficción y realidad en "Les Bienveillantes" de Jonathan Littell
Authors: Borshchak Olha , Hernández García María Luisa
Published: June 2016

En el presente trabajo se analiza Les Bienveillantes, novela que ficciona las memorias atormentadas de un nazi. A través de su lectura se viaja a los infiernos del holocausto, de la guerra y de una conciencia sin anclajes éticos ni estéticos, narrados por una mente perversa que no se conmueve ante las atrocidades más profundas. Tras contrastar a lo largo de su trama ficción y realidad, se destaca, a la luz de los debates sobre la reescritura de la Historia, la operatividad de esta novela para captar y transmitir la verdad de lo ocurrido favoreciendo de ese modo el desarrollo de una conciencia responsable y la no repetición de los hechos.

Este artigo procura incitar algumas reflexões sobre a relação entre o homem e o tempo. Metodologicamente, o texto assume uma abordagem qualitativa apoiada por pesquisa bibliográfica. Inicialmente, destaca-se o poder exercido por um instrumento originalmente concebido para servir a humanidade: o relógio. Em seguida, são apresentados elementos que indicam como a relação do homem com o tempo produz diversas aceitações, contradições e rupturas na sociedade moderna. Discute-se a estreita vinculação entre o tempo na modernidade e os conceitos de trabalho, consumo, produtividade e desempenho.  Por fim, o texto denuncia a existência de forças sociais e econômicas que promovem a ditadura da "produtividade e desempenho" no âmbito da academia. Inclusive, Essas forças se mostram insensíveis às consequências nefastas tanto para a pesquisa quanto para a produção acadêmica.

The influence on birthweight of maternal living conditions a decade prior to giving birth
Authors: Singhammer John , Mittelmark Maurice B. , Daltveit Anne-Kjersti , Tell Grethe S.
Published: June 2016

The study’s aim was to correlate measures of mothers’ socio-economic status, a decade prior to giving birth, with their children’s birthweight. As part of a larger study, information on birth characteristics from 706 babies born 1970-73 were linked with census data obtained from their mothers near the time of birth as well as one decade earlier. The 706 individuals were selected at random from two national surveys in 1998 and 2000 and traced back to the time of birth in the period 1970-73. Information on birth characteristics was linked to census data obtained from the mothers in 1960 and 1970. Included was information on parent’s living conditions (e.g. income, type of dwelling, indoor plumbing, telephone, number of people in the household). Information on mother’s health during pregnancy, a decade before childbirth and near childbirth, and data on mothers’ and the infants’ health at birth was obtained from the Medical Birth Registry of Norway. In analysis that included both early and current socio-economic conditions maternal education and rural residency at the time of giving birth were observed as statistical significant predictors of birthweight. Results were adjusted for maternal age, parity, plurality, gender and diagnoses before and during pregnancy, all factors observed to attenuate birthweight. Indicators of women’s socio-economic conditions a decade prior to giving birth were not significantly associated with birthweight. These findings do not clearly support suggestions in the literature that an infant’s vitality may be influenced by the family’s socio-economic conditions years before birth.
Intervention studies for improving global health and health care: An important arena for epidemiologists
Authors: Kvåle Gunnar , Sommerfelt H. , Fylkesnes K.
Published: June 2016

Marginalised populations in many low- and middle-income countries experience an increasing burden of disease, in sub-Saharan Africa to a large extent due to faltering health systems and serious HIV epidemics. Also other poverty related diseases (PRDs) are prevalent, especially respiratory and diarrhoeal diseases in children, malnutrition, maternal and perinatal health problems, tuberculosis and malaria. Daily, nearly 30,000 children under the age of 5 die, most from preventable causes, and 8,000 people die from HIV infections. In spite of the availability of powerful preventive and therapeutic tools for combating these PRDs, their implementation, especially in terms of equitable delivery, leaves much to be desired. The research community must address this tragic gap between knowledge and implementation. Epidemiologists have a very important role to play in conducting studies on diseases that account for the largest share of the global disease burden. A shift of focus of epidemiologic research towards intervention studies addressing health problems of major public health importance for disadvantaged population groups is needed. There is a need to generate an evidence-base for interventions that can be implemented on a large scale; this can result in increased funding of health promotion programs as well as enable rational prioritization and integration between different health interventions. This will require close and synergetic teamwork between epidemiologists and other professions across disciplines and sectors. In this way epidemiologists can contribute significantly to improve health and optimise health care delivery for marginalized populations.

Tuberculosis in the 21st century: an emerging pandemic?
Authors: Bjune Gunnar
Published: June 2016

Since the mid-1980ies the world has witnessed a dramatic increase in tuberculosis. Our knowledge of tuberculosis epidemiology was established during the previous epidemic that, at least in Europe, took two hundred years from rise to fall. It is difficult to understand the new epidemic if we assume that the genetics of the host-parasite relationship is unchanged from the previous epidemic.The paper discusses how both host and parasite genetics may have changed. Molecular epidemiology done in Archangel, Russia, where most of the classical reasons for increase in tuberculosis were absent, indicated that strains of Mycobacterium tuberculosis with changed biological properties could be responsible. Strains belonging to the so-called Beijing family were strongly associated with primary drug resistance and caused clusters ten times as big as “traditional” strains.The paper describes how the research consortium takes these observations further to explore the importance of “new” strains of tubercle bacilli in the on-going pandemic. What are the changes in biological properties and what genetic changes do they reflect? The previous epidemic may have changed the genetic susceptibility of the human host by selection, but what has constituted a selective pressure for the bacillary population? The two most dramatic changes in the environment of M. tuberculosis are mass introduction of chemotherapy and BCG vaccination. We explore further the nature of drug resistance in these strains and the possibility that BCG may fail to protect against bacilli of the new pandemic.Lastly the paper points at some action that can be taken instantly and that may have a major impact on transmission, even before the questions mentioned above are answered. The clue here is to shorten the time of transmission by a rapid test to secure early diagnosis and treatment. What is needed, however, is not a diagnostic test for tuberculosis, but a simple screening test with high sensitivity that could tell us whom among the numerous people who have a chronic cough and systemic symptoms who are the true “tuberculosis suspects” eligible for rapid examination of sputum by smear microscopy

Published: June 2016

The purpose of this retrospective study was to compare the outcome for dogs with surgically treated large versus small intestinal volvulus between October 2009 and February 2014. A total of 15 dogs met the inclusion criteria and underwent an abdominal exploratory. Nine dogs were diagnosed with large intestinal volvulus during the study period, and all nine had surgical correction for large intestinal volvulus. All dogs were discharged from the hospital. Of the seven dogs available for phone follow-up (74 to 955 days postoperatively), all seven were alive and doing well. Six dogs were diagnosed with small intestinal volvulus during the study period. One of the six survived to hospital discharge. Three of the six were euthanized at the time of surgery due to an extensive amount of necrotic bowel. Of the three who were not, one died postoperatively the same day, one died 3 days later, and one dog survived for greater than 730 days. Results concluded that the outcome in dogs with surgically corrected large intestinal volvulus is excellent, compared with a poor outcome in dogs with small intestinal volvulus. The overall survival to discharge for large intestinal volvulus was 100%, versus 16% for small intestinal volvulus.

Published: June 2016

The fruit harvesting is a key factor involving both product quality and profitability. Particularly, mechanical harvesting of traditional oil olive orchards is hint by tree training system for manual harvesting, tree size and several and slanted trunks which makes difficult trunk shaker work. Therefore, canopy shaker technology could be a feasible alternative to develop an integral harvester able to work on irregular canopies. The aim of this research was to determine vibration parameters applied to the olive tree for efficient mechanical harvesting by canopy shaker measuring fruit removal efficiency and debris. In this work, a continuous lateral canopy shaker harvester has been developed and tested on large olive trees in order to analyse the operating harvester parameters and tree properties to improve mutual adaptation. Vibration amplitude and frequency, rod density and ground speed were assessed. Vibration amplitude and frequency beside ground speed were decisive factors on fruit removal efficiency. Increasing rod density has not influenced on removal efficiency although it increased significantly debris. Promising results has been reached with 77.3% of removal efficiency, applying a 28 s shaking duration, 0.17 m amplitude vibration and 12 rod drum. This result was obtained reporting 0.26 s of accumulative shaking time over 200 m/s2 resultant acceleration. The canopy shaker mechanism enabled more than 65% of detached fruits to fall vertically, facilitating catch fruit. In order to improve removal efficiency it is advisable to adapt trees, set high amplitude in the shaker mechanism, and enhance the contact time between rods and tree.
A Comparative Study on Beliefs of Grammar Teaching between High School English Teachers and Students in China
Authors: Deng Fangfang , Lin Yuewu
Published: June 2016

Grammar is “a system of rules governing the conventional arrangement and relationship of words in a sentence” (Brown 1994) which can facilitate the acquisition of a foreign language and is conducive for cultivating comprehensive language competence. Most teachers regard grammar as a frame of English learning. The grammar teaching beliefs held by teachers can affect their practical teaching behaviors in class, thus can have different teaching results in the end. Therefore, through quantitative and qualitative research, this paper aims to investigate the present status of grammar beliefs of high school students as well as teachers’ beliefs and their grammar teaching behaviors, analyze and compare the similarities and differences between them. The result shows that teachers’ grammar teaching has the tendency of communicative teaching while students’ grammar beliefs have the characteristic of integration of communicative and traditional grammar teaching. Teachers’ grammar teaching behaviors can basically be consistent with their grammar teaching beliefs.
A Cross-Cultural Analysis of Advertisements from High-Context Cultures and Low-Context Cultures
Authors: Bai He
Published: June 2016

With the development of economy and the change of social culture, advertisements have penetrated our life slowly and done a lot to the commercial markets. Advertisements have often been analyzed in a stylistic way for its unique language style. But language is an important part, as well as a carrier, of culture. Advertising language, as other kinds of languages, is also a significant component of culture and is a comprehensive collection of different aspects of culture. In turn, it reflects culture in its own way. A cultural pattern, put forward by Edward T. Hall and called “high context” and “low context” communication, will be focused on to analyze different advertisements from these two cultures.

Dividend Policy Decision across African Countries
Authors: Yensu Joseph , Adusei Charles
Published: June 2016

This paper provides analysis of the trends in dividend policy and differentials in firm and country specific factors for payers and non-payers of dividends and examines the predictions concerning the amount of dividends paid by listed non-financial firms in African countries. Using a panel dataset over the period 1994-2011 from 13 African countries, the study found that dividend payers are more profitable, have larger firm size, greater investment, higher retention of earnings and less financial leverage than non-paying firms. The results show that in countries where the GDP per capita is low, firms are more likely to pay dividends. The level of corruption is high for non-payers of dividends. The study also found a positive significant relationship between dividend payout, profitability, investment opportunities and firm size. However, a significant negative relationship was reported between dividend payout, financial leverage, corruption and gross domestic product per capita. The study further found that the dividend trends were very low and stable. The conclusion, therefore, indicates that although firm specific factors are important in Africa in determining dividend policy regarding payout, country specific factors play very significant roles in determining the dividend payout of African firms.

François Bienvenu y la popularización científica en la Ilustración: demostraciones experimentales, entretenimiento y públicos de la ciencia
Authors: Suay-Matallana Ignacio , Bertomeu Sánchez José Ramón
Published: June 2016

En el presente trabajo se estudian las prácticas experimentales realizadas por demostradores itinerantes en la Ilustración. Se mostrará el recorrido por España de uno de los demostradores más populares, François Bienvenu, con el fin de analizar diversos aspectos relacionados con la popularización de la ciencia: los espacios, los públicos destinatarios y la cultura material. Las demostraciones estudiadas muestran que sus experiencias de física y química cumplieron diferentes funciones, relacionadas tanto con la diversión y el espectáculo, como con la formación y la utilidad de los fenómenos naturales. Asimismo, se discutirá la labor de los demostradores de ciencias en la creación, el desarrollo y la popularización de novedades de la física y la química, así como en la circulación de prácticas experimentales e instrumentos científicos.
Explaining a rare null relationship between group identification and social protest through a relational form of coping with low group status
Authors: van Zomeren Martijn , Susilani Nella , Berend Simin
Published: June 2016

Primary and meta-analytic research strongly suggests that group identification motivates disadvantaged group members for social protest to achieve social change. However, most studies on social protest are conducted in contexts that are already conducive to this positive relationship (i.e., conditions of hope and scope for social change). Two studies of Indonesian ethnic minority group members’ coping with low group status add to this literature by testing (a) whether group identification motivated social protest in a cultural context in which group identity is valued while hope and scope for social change are lacking, and (b) alternatively, whether individuals engage in a relational form of coping that revolves around seeking shelter in social relationships to protect well-being. In both studies (N = 80 and N = 132), we predicted and found a rare null correlation between group identification and social protest, and rather strong support that coping with low group status revolved around seeking shelter in social relationships. We discuss the theoretical and practical implications of our findings for identity management and relationship regulation processes in contexts that lack hope and scope for social protest to achieve social change.
Survival Analysis of Duration of Breastfeeding and Associated Factors of Early Cessation of Breastfeeding in Ethiopia
Authors: Molla Melkamu , Berhe Leakemariam
Published: June 2016

The purpose of this study was to assess the duration of breastfeeding among women of reproductive age in Ethiopia and to identify determinants associated with early cessation of breastfeeding. Data for the study were drawn from the Ethiopia Demographic and Health Survey 2005. The study included mothers of 9,066 children from nine regional states and two city administrations. The Kaplan-Meier and stratified Cox’s hazard model were employed for the analysis of breastfeeding-related data. The Kaplan-Meier survival estimate showed that the probability of mothers who continue to breastfeeding was high (97.3%) for the first month. The breastfeeding rates then declined to 92.5% at 6 months, 78.4% at 12 months, 37% at 24 months and 8.3% at 48 months. The mean and median duration of breastfeeding in Ethiopia were 25.64 and 24.00 months respectively. The stratified Cox regression analysis revealed that younger mothers, mothers who had lived in urban area, mothers having higher education, higher maternal parity, early pregnant and being a Muslim and protestant were significant determinants of early cessation of breastfeeding in Ethiopia. Then, we recommend that the breastfeeding-promotion programs in Ethiopia should give special attention to young mothers, those who lived in urban areas, mothers with higher education, those who have higher parity, those who have early pregnancy and who are Muslims and Protestants since these mothers tend to breastfeed their child for a relatively shorter period of time.
La dimension corporelle, support pour assouplir le clivage dans les soins aux Auteurs de Violence Sexuelle
Authors: Claudette Hugon , Sophie Villain
Published: June 2016

La clinique de la violence sexuelle nous confronte au registre du primaire voire de l’originaire. Le corporel, la représentation et le mouvement y sont encore intriqués. Les recours à l’acte prennent racines dans les achoppements de ces fondements identitaires, qui émanent du corporel. Les groupes thérapeutiques permettent l’émergence d’éléments non verbaux, qui peuvent y être contenus et transformés dans le sens d’une décorporation et d’une mise en représentation. Il y est donc question d’articulation entre le registre primaire et secondaire ainsi qu’entre la voie de l’affectif et la voie de l’idéal.
Optical-disk-based imaging system to be used as an optical microscope
Authors: Shima Takayuki , Fujimaki Makoto , Awazu Koichi
Published: June 2016

An optical disk surface is scanned spirally by laser light, as in the case of digital versatile discs, and a reflectance image is formed by rearranging the scanned intensity results. A prototype system is developed for imaging with a rotary encoder equipped to precisely control the disk rotation angle. We measured Escherichia coli dispersed on an optical disk sample surface and successfully obtained an image that is identical to that obtained using an optical microscope. The system is advantageous as an optical sensor for detecting sub-micrometer- to micrometer-order substances on a large-area surface.
Two-dimensional simulations of a VHF H2 plasma for different discharge gaps and gas pressures

Published: June 2016

A two-dimensional simulation on a VHF H2 plasma (60 MHz) was performed using the plasma hybrid code, and plasma parameters were examined as a function of pressure for different discharge gaps. It was found that as the pressure increased, the H3
+ and H+ densities as well as the electron density had a maximum at a certain pressure, and the maximum shifted to high pressures as the discharge gap decreased. On the other hand, the H2
+ density decreased with the increase in pressure, independent of the discharge gap. The axial profiles of the H+, H2
+, and H3
+ densities showed that dominant ions were H3
+ in our pressure range.
Numerical study of breakdown pattern induced by an intense microwave under nitrogen and argon gases
Authors: Takahashi Masayuki , Ohnishi Naofumi
Published: June 2016

Filamentary plasma induced by microwave beam irradiation was reproduced in nitrogen and argon by combining fluid or particle plasma models with electromagnetic wave propagation. Transport coefficients used in the fluid model are estimated from particle simulation to maintain consistency of the breakdown structure between the fluid and particle models. A discrete structure was obtained using the one-dimensional (1D) fluid model, because a standing wave is generated in front of the plasma when the incident microwave beam is reflected by the overcritical plasma, which agrees with the breakdown structure obtained using the 1D particle model. A 2D plasma filament was also reproduced using the fluid model in nitrogen and argon. Reflection of the incident microwave in argon becomes stronger than that in nitrogen because of the denser argon plasma. Change in filament shape is induced in argon because the electric field is deformed at the plasma tip owing to stronger wave reflection from the neighboring filament. The propagation speed of the plasma front becomes larger in argon breakdown because of the larger ionization frequency and the larger diffusion coefficient.
Graphene on C-terminated face of 4H-SiC observed by noncontact scanning nonlinear dielectric potentiometry
Authors: Yamasue Kohei , Fukidome Hirokazu , Tashima Keiichiro , Suemitsu Maki , Cho Yasuo
Published: June 2016

We studied graphene synthesized on the C-terminated face (C-face) of a 4H-SiC substrate by noncontact scanning nonlinear dielectric potentiometry. As already reported by other researchers, multilayer graphene sheets with moiré patterns were observed in our sample, which indicates the existence of rotational disorder between adjacent layers. We found that the potentials of graphene on the C-face are almost neutral and significantly smaller than those observed on the Si-terminated face (Si-face). In addition, the neutrality of potentials is not affected by various topographic features underlying the multilayer graphene sheets. These results indicate that graphene on the C-face of SiC is decoupled or screened from the underlying structures and substrate, unlike graphene on the Si-face.
