SDNyquist platform for big data transmission
Venue: 2016 15th International Conference on Optical Communications and Networks (ICOCN)

To realize high speed big data transmission, we combine the advantages of Nyquist Super channel and Software Defined Optical Networks (SDON) thus establishing the SDNyquist platform that dynamically manages the whole optical network. This platform has the features of flexible resource allocation, high spectrum efficiency and global network optimization with the help of Routing, Modulation Level and Spectrum Allocation (RMLSA) algorithm. We compare the performance of different SDNyquist platforms based on RMLSA and traditional RSA. Experimental results show that our SDNyquist platform based on RMLSA has high potential in improving network performance.
Government subsidized R&D and Firm Innovation: Evidence from China

This study investigates the effects of government R&D programs on firm innovation outputs, which are measured by the number of patents, sales from new products, and exports. Particularly, we examine the effects of Innovation Fund for Small and Medium Technology based Firms (Innofund) which is one of the largest government R&D programs that support R&D activities of small and medium sized enterprises in China. Using a panel dataset on Chinese manufacturing firms from 1998 to 2007, we find that Innofund backed firms generate significantly higher technological and commercialized innovation outputs compared with their non Innofund backed counterparts and the same firms before winning the grant. Moreover, the changes in the governance of Innofund in 2005 from a centralized to a decentralized one because of policy amendments have significant effects on the effectiveness of the program. Specifically, the magnified effects of Innofund on technological innovation outputs become significantly stronger after the governance of Innofund becomes more decentralized. Identification problems are addressed by utilizing both propensity score matching and two stage estimation approaches.
Funding Forms, Market Conditions, and Dynamic Effects of Government R&D Subsidies: Evidence from China

We examine various factors that influence the effects of government subsidized research and development (R&D) programs on firm productivity. Based on a panel dataset of Chinese firms, we find the effects of the Innovation Fund for Small and Medium Technology Based Firms (Innofund) are dynamic over time and are heterogeneous depending on funding forms and the level of marketization and economic development across regions. In general, Innfound has significant and positive effects on firm productivity in both the short and long run. However, the short term effects of Innofund are stronger than the long term ones. Additionally, the positive effects of Innofund are stronger for firms backed by interest free bank loans than those supported by appropriation. Meanwhile, Innofund has stronger positive effects in provinces that are less market oriented or less developed economically. Finally, the short term effects of Innofund stay stronger than the long term ones even after we control the funding forms and the market conditions across regions. Identification and selection concerns are addressed through the propensity score matching approach and two stage estimation.
Accelerating Big Data processing chain in Image Information Mining using a hybrid HPC approach
Venue: 2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)

The recent development in sensor technology shows the unprecedented growth of Remote Sensing (RS) data archives Big Data. However, this growth in RS archives has resulted in many processing challenges. The three V's of big data Volume, Velocity and Variety is highly relevant in situations such as flood, earthquake disaster, where real/near real time processing of data from different RS data sources is vital to deploy rescue operations. In this work, we have demonstrated a high performance analytics approach Message Passing Interface (MPI) along with the emerging Graphics Processing Units (GPUs) (i.e. hybrid MPI+GPU) technology to overcome the big data processing limitation. The different processing/analysis stages of our Spatial Image Information Mining (SIIM) system are parallelized using the above approach. The experimental results for parallel segmentation process show the applicability of MPI+GPU hybrid approach in disaster scenario.
Two stage replication of previous genome wide association studies of AS3MT CNNM2 NT5C2 gene cluster region in a large schizophrenia case control sample from Han Chinese population
Venue: Schizophrenia Research

Schizophrenia is a devastating psychiatric condition with high heritability. Replicating the specific genetic variants that increase susceptibility to schizophrenia in different populations is critical to better understand schizophrenia. CNNM2 and NT5C2 are genes recently identified as susceptibility genes for schizophrenia in Europeans, but the exact mechanism by which these genes confer risk for schizophrenia remains unknown. In this study, we examined the potential for genetic susceptibility to schizophrenia of a three gene cluster region, AS3MT CNNM2 NT5C2. We implemented a two stage strategy to conduct association analyses of the targeted regions with schizophrenia. A total of 8218 individuals were recruited, and 45 pre selected single nucleotide polymorphisms (SNPs) were genotyped. Both single marker and haplotype based analyses were conducted in addition to imputation analysis to increase the coverage of our genetic markers. Two SNPs, rs11191419 (OR=1.24, P=7.28x10( 5) and rs11191514 (OR=1.24, P=0.0003) with significant independent effects were identified. These results were supported by the data from both the discovery and validation stages. Further haplotype and imputation analyses also validated these results, and bioinformatics analyses indicated that CALHM1, which is located approximately 630kb away from CNNM2, might be a susceptible gene for schizophrenia. Our results provide further support that AS3MT, CNNM2 and CALHM1 are involved with the etiology and pathogenesis of schizophrenia, suggesting these genes are potential targets of interest for the improvement of disease management and the development of novel pharmacological strategies.
Reliability analysis and updating of deteriorating systems with dynamic Bayesian networks

To estimate and update the reliability of deteriorating structural systems with inspection and monitoring results, we develop a modeling and computational framework based on dynamic Bayesian networks (DBNs) The framework accounts for dependence among deterioration at different system components and for the complex structural system behavior. It includes the effect of inspection and monitoring results, by computing the updated reliability of the system and its components based on information from the entire system. To efficiently model dependence among component deterioration states, a hierarchical structure is defined. This structure facilitates Bayesian model updating of the components in parallel. The performance of the updating algorithm is independent of the amount of included information, which is convenient for large structural systems with detailed inspection campaigns or extensive monitoring. The proposed model and algorithms are applicable to a wide variety of structures subject to deterioration processes such as corrosion and fatigue, including offshore platforms, bridges, ships, and aircraft structures. For illustration, a Daniels system and an offshore steel frame structure subjected to fatigue are investigated. For these applications, the computational efficiency of the proposed algorithm is compared with that of a standard Markov Chain Monte Carlo algorithm and found to be orders of magnitude higher.
Community theatre as instrument for community sensitisation and mobilisation

Environmental protection, sustainable economic development and good governance are important issues of the century, and theatre can play an important role in addressing them. This paper contends that community theatre is likely to offer a sustainable alternative approach towards addressing these and other current myriad issues confronting the African continent. Recognising that rural communities are proactive agents of change, their exclusion from the design, development and implementation of community theatre activities, coupled with the difficulties in sourcing and securing funding for the promotion of conventional theatre activities, are only a few of the problems likely to be encountered. The paper highlights some of the potential implementation constraints and proposes strategies that could be deployed to effectively develop and establish community theatre as part of the African traditional system with a view to influencing change at all levels of the community in particular and the nation at large.
The Formation of Citizenship Through Community Theatre. A Study in Aguascalientes, Mexico

The aim of the research was to examine if adolescents can develop abilities of democratic interaction through Community Theatre.  Firstly, two instruments were applied a questionnaire covering socio moral problems, of the students and a Questionnaire, covering the Educational Ideologies of the professors. Then, a theatrical intervention was realized at middle school students in Aguascalientes City, based on the objectives of the formation of Citizenship as stated at the National Curriculum.  Students themselves stated a change in their attitude during the intervention, which was also observed and registered at the field diary and at the written evaluations. For this reason, we claim that Community theater could be used as a transdisciplinary method for teaching democratic skills, as it creates a public sphere where the students can develop democratic behavior.  Further studies on the subject are required, especially concerning the time and the sample as the research had a two month duration and was conducted at a limited population.  The contribution of this project was the introduction of Community Theatre at the service of the Citizenship Education, promoting the artistic education as a means of the formal education in the search for personal and social democratic development and could be considered in an educational reform.
Globules and Pillars in Cygnus X I. Herschel Far infrared imaging of the Cyg OB2 environment

The radiative feedback of massive stars on molecular clouds creates pillars, globules and other features at the interface between the HII region and molecular cloud. We present here Herschel observations between 70 and 500 micron of the immediate environment of the Cygnus OB2 association, performed within the HOBYS program. All structures were detected based on their appearance at 70 micron, and have been classified as pillars, globules, evaporating gasous globules (EGGs) proplyd like objects, and condensations. From the 70 and 160 micron flux maps, we derive the local FUV field on the PDR surfaces. In parallel, we use a census of the O stars to estimate the overall FUV field, that is 10^3 10^4 G_0 close to the central OB cluster (within 10 pc) and decreases down to a few tens G_0, in a distance of 50 pc. From a SED fit to the four longest Herschel wavelengths, we determine column density and temperature maps and derive masses, volume densities and surface densities for these structures. We find that the morphological classification corresponds to distinct physical properties. Pillars and globules have the longest estimated photoevaporation lifetimes, a few 10^6 yr, while all other features should survive less than that. These lifetimes are consistent with that found in simulations of turbulent, UV illuminated clouds. We propose a tentative evolutionary scheme in which pillars can evolve into globules, which in turn then evolve into EGGs, condensations and proplyd like objects.
Young Children Selections of the Physical Elements in the Preschool Environment

The camera is a tool which can give young children an opportunity to express their thoughts and provide adults with a tangible evidence of their preferences. This study is to explore young children thoughts and preferences of their preschool environment through words and photographs. Eighteen young children of age four and five was given a camera to take pictures of their preschool in pairs. Children were interviewed on their photographs selection and their conversation was recorded. Results show there are differences and similarities on the children preferences on the physical elements in the preschool environment.   young children, preferences, photographs, camera, preschool environment
The first 2 year home environment in relation to the new onset and remission of asthmatic and allergic symptoms in 4246 preschool children.
Venue: The Science of the total environment

The home environment can influence childhood allergies and respiratory health but there is little information on associations between early life exposure at home and new onset and remission of the asthmatic or allergic symptoms in preschool children. A questionnaire survey was performed in a random cluster sample of 4246 preschool children in Urumqi, China. Information on the home environment (perceptions of odors and indicators of pollution sources) and children's health (wheeze, rhinitis and eczema) was collected for the first 2 years of life and the last year (before answering the questionnaire) from one of the parents or another guardian of the child. Associations between the home environment the first 2 years of life and new onset and remission of childhood symptoms were analyzed by multiple logistic regression. Home environment factors reported for the first 2 years of life were consistently positively associated with new onset of symptoms and negatively associated with remission of symptoms. Visible mold (OR 1.46, 95% CI 1.12 1.90) moldy odor (OR 2.15, 95% CI 1.45 3.18) air dryness (OR 1.31, 95% CI 1.08 1.59) stuffy odor (OR 1.25, 95% CI 1.01 1.54) and parental smoking (OR 1.36, 95% CI 1.13 1.65) were associated with new onset of symptoms. These factors were negatively associated with the remission of symptoms. In conclusion, mold contamination at home (moldy odor/visible mold) poor indoor air quality (stuffy odor, air dryness) and exposure to environmental tobacco smoke (ETS) in the first 2 years of life can increase the incidence of asthmatic and allergic symptoms and decrease the remission from these symptoms in preschool children.
Should It Stay or Should It Go Now? Smartphones and Relational Health

Since introduced in the mid 2000s, smartphones have become widely used, particularly among young adults. With the ability to connect to others across numerous modalities and occupy one's time, these devices have become personal extensions for many people. However, recent research suggests that young people are particularly likely to find these devices indispensable, even to the point of feeling that they cannot live without them. The current study tests whether smartphone use and smartphone dependency affects the health of romantic relationships among college aged adults. Participants were asked to report on their own smartphone use and dependency as well as the perceived use and dependency of their partner. Results reveal that participants' smartphone dependency is significantly linked to relationship uncertainty, while partners' perceived smartphone dependency predicts less relationship satisfaction. Moreover, results suggest that smartphone use, in general, does not affect relational health. Thus, it appears that it is the psychological reliance on these devices, and one's need to constantly be connected with his or her smartphone, that potentially affects relationships and not actual use.
Consistent quadrangulation for shape collections via feature line co extraction
Venue: Comput. Aided Des.

This paper presents a method that takes a collection of 3D surface shapes, and produces a consistent and individually feature preserving quadrangulation of each shape. By exploring the correspondence among shapes within a collection, we coherently extract a set of representative feature lines as the key characteristics for the given shapes. Then we compute a smooth cross field interpolating sparsely distributed directional constraints induced from the feature lines and apply the mixed integer quadrangulation to generate the quad meshes. We develop a greedy algorithm to extract aligned cut graphs across the shape collection so that the meshes can be aligned in a common parametric domain. Computational results demonstrate that our approach not only produces consistent quad meshes across the entire collection with significant geometry variation but also achieves a trade off between global structural simplicity for the collection and local geometry fidelity for each shape. We propose a framework to produce consistent quadrangulations for a shape collection.We propose an efficient method for extracting feature lines from the shape collection.We propose a practical greedy algorithm for extracting the aligned cut graphs.
Spectral Generalized Multi dimensional Scaling
Venue: International Journal of Computer Vision

Multidimensional scaling (MDS) is a family of methods that embed a given set of points into a simple, usually flat, domain. The points are assumed to be sampled from some metric space, and the mapping attempts to preserve the distances between each pair of points in the set. Distances in the target space can be computed analytically in this setting. Generalized MDS is an extension that allows mapping one metric space into another, that is, MDS into target spaces in which distances are evaluated numerically rather than analytically. Here, we propose an efficient approach for computing such mappings between surfaces based on their natural spectral decomposition, where the surfaces are treated as sampled metric spaces. The resulting spectral GMDS procedure enables efficient embedding by incorporating smoothness of the metric structure into the problem, thereby substantially reducing the complexity involved in its solution while practically overcoming its non convex nature. The method is compared to existing techniques that compute dense correspondence between shapes. Numerical experiments of the proposed method demonstrate its efficiency and accuracy compared to state of the art approaches especially when isometry invariance is a dominant property.
Paraphrasing Strategy Instruction for Struggling Readers

Reading comprehension is important for academic success and is a skill required for many activities in school and beyond. This study investigated the effects of the TRAP (Think before you read, Read a paragraph, Ask myself, "What was this paragraph mostly about?" and Put it into my own words) paraphrasing strategy taught using the Self Regulated Strategy Development model. Participants were seven middle school students identified as fluent readers who experienced difficulty with comprehension. All instruction for the participants was in pairs or small groups. Results indicate that the TRAP strategy increased reading comprehension as measured by the percentage of text recall and short answer questions. Ideas for future research and implications are discussed.
Plagiarism in English academic writing: A comparison of Chinese university teachers' and students' understandings and stances

Research on plagiarism has largely left English as a Foreign Language (EFL) teachers out of the picture. This study set out to bridge the gap by comparing how 142 Chinese university EFL teachers and 270 undergraduate students viewed exemplars of unacknowledged copying and unattributed paraphrasing, two forms of intertextuality generally regarded as plagiarism in Anglo American academia. More than half of the teacher participants had overseas academic experience. Quantitative and qualitative analyses found that the participants, though understanding plagiarism in English academic writing differently from Anglo American academia, clearly disapproved of recognized cases of plagiarism. The analyses also revealed that greater knowledge of and harsher stances on both types of transgressive intertextuality were associated with wider exposure to and more experience in English academic writing. Furthermore, the participants had more similar understandings of unacknowledged copying than of unattributed paraphrasing and took harsher stances on the former. These findings highlight complex and nuanced understandings of plagiarism and point to the crucial role of academic socialization in shaping knowledge of and attitudes toward plagiarism.
Estado del conocimiento del personal de salud sobre la Alimentacion del nino menor de dos anos y la anemia en El preescolar

Una alimentacion sana es el resultado de habitos alimentarios saludables. Las guias alimentarias constituyen un instrumento educativo que transmite conocimientos cientificos sobre la alimentacion y la nutricion en forma de mensajes practicos que facilitan la seleccion y consumo de los alimentos. En el nino menor de 2 anos de edad estas guias cobran particular importancia debido a la necesidad de formar habitos alimentarios saludables desde la temprana edad. La implementacion de las guias alimentarias hace necesario evaluar los conocimientos del personal de salud que las aplicara.  Obtener informacion sobre los conocimientos del personal en relacion con la lactancia materna, la alimentacion del nino menor de 2 anos, y la anemia en el preescolar.  Se aplico una encuesta de medicion de conocimientos en 1,376 profesionales de la salud como paso previo a la implementacion de las guias alimentarias. El cuestionario contaba de sendos bloques de preguntas, el primero relacionado con la alimentacion del menor de 2 anos, y el segundo sobre la anemia en los menores de 5 anos y su repercusion en la salud del nino. Cada bloque de preguntas se califico en base al numero de respuestas correctas.  El 25.0% de los profesionales encuestados, y el 11.0% de ellos, respondieron "Mal" a las respuestas hechas sobre la alimentacion del menor de 2 anos y la anemia en el preescolar, respectivamente.  Los profesionales de salud aun no dominan los contenidos de las guias alimentarias sobre la duracion de la lactancia materna continuada hasta los dos anos de edad del nino, y la alimentacion complementaria. Tampoco se conocen cabalmente el alcance y las repercusiones de la anemia en el preescolar. La medicion de conocimientos sobre contenidos de alimentacion y nutricion mediante encuestas estructuradas puede constituir una forma agil y sencilla de evaluacion del impacto de la implementacion de las guias alimentarias.
Data Pre processing of Student e Learning Logs

Educational data mining faces the challenge of systematic knowledge discovery in large data streams to support educational decision making. While much research effort has been made in examining study patterns with various data mining algorithms, how to prepare the data suitable and effective for these mining algorithms (i.e. the phase of data pre processing) has not been investigated in detail. This paper presents a specific data pre processing case for educators who are keen on investigating student online reading behavior using sequential pattern analyses. The implications of data pre processing were also discussed.
