GRASS GIS ON HIGH PERFORMANCE COMPUTING WITH MPI, OPENMP AND NINF-G PROGRAMMING FRAMEWORK

GRASS GIS (Geographical Resources Analysis Support System) is a free, open source software and has been used for Remote Sensing (RS) and Geographic Information System (GIS) data analysis and visualization. Inside GRASS, different modules have been developed for processing satellite images. Currently, GRASS uses databases to handle large datasets and the performance and capabilities of GRASS for large datasets can be greatly improved by integrating GRASS modules with parallel and distributed computing. Multi computer based distributed systems (clusters and Grids) have a large processing capacity for a lower cost, naturally, choice turns towards developing High Performance Computing (HPC) applications. However, it is not an easy job to port GRASS modules directly to HPC environment. The developers of satellite image processing applications need to solve the problem of both data and task distribution, or how to distribute data and tasks among single or multiple clusters environment. The workload in HPC, the bandwidth, the processors speed, parameters of evaluation methods and data size are additional concerning factors. GRASS modules, i.e. i) “i.vi” is developed by Kamble and Chemin (2006) to process 13 vegetation indices, ii) “i.lmf” is developed by Akhter et al. (2008) to remove the atmospheric effects from RS images and iii) “r.gaswap” is developed by Akhter et al. (2006) to find out the crop parameters those are not directly visible from RS images, will be discussed as three case studies to developed GRASS module framework on HPC. Developing the methodology, which enables to run GRASS GIS environment for RS images processing on HPC systems, will be the main concerning issue of this paper. Additionally, different implementations for distributed GRASS models will be discussed on three different programming platforms (MPI, Ninf-G and OpenMP) and their performance will also be presented in this paper.
Achieving Efficient and Secure Data Acquisition for Cloud-Supported Internet of Things in Smart Grid

Cloud-supported Internet of Things (Cloud-IoT) has been broadly deployed in smart grid systems. The IoT front-ends are responsible for data acquisition and status supervision, while the substantial amount of data is stored and managed in the cloud server. Achieving data security and system efficiency in the data acquisition and transmission process are of great significance and challenging, because the power grid-related data is sensitive and in huge amount. In this paper, we present an efficient and secure data acquisition scheme based on ciphertext policy attribute-based encryption. Data acquired from the terminals will be partitioned into blocks and encrypted with its corresponding access subtree in sequence, thereby the data encryption and data transmission can be processed in parallel. Furthermore, we protect the information about the access tree with threshold secret sharing method, which can preserve the data privacy and integrity from users with the unauthorized sets of attributes. The formal analysis demonstrates that the proposed scheme can fulfill the security requirements of the Cloud-IoT in smart grid. The numerical analysis and experimental results indicate that our scheme can effectively reduce the time cost compared with other popular approaches.
“Kracking” the Missing Data Problem: Applying Krackhardt's Cognitive Social Structures to School-Based Social Networks

Social network analysis can enrich school-based research on children's peer relationships. Unfortunately, accurate network analysis requires near-complete data on all students and is underutilized in school-based research because of low rates of parental consent. This article advocates Krackhardt's cognitive social structures (CSS) as a solution to the problem of missing data in social network research. It compares CSS to other common strategies for dealing with missing data and shows how CSS can be used to yield more complete and precise network data. The article also uses an example of a sixth-grade classroom network to demonstrate the application of CSS and potential analyses.
Fatherhood stories: Grandparents, grandchildren, and gender differences

The meanings of fatherhood conveyed in grandparent stories told by adult grandchildren vary both by the sex of the grandchild and by the sex of the grandparent who figures in the story. An inductive analysis was conducted of fatherhood stories involving grandparents as told by adult grandchildren (N = 79). Findings suggest that grandsons drew on stories about grandparents to present fatherhood as centered on work and recreation, and to suggest that women play supporting roles. Granddaughters’ stories were less positive, and suggested that women must make up for perceived deficiencies of fathers. This qualitative study is the first to explore same- and cross-sex similarities and differences in grandparents’ socialization of grandchildren into meanings of good fathering.
Efficacy Beliefs of Special Educators: The Relationships Among Collective Efficacy, Teacher Self-Efficacy, and Job Satisfaction

In order to examine the relationship between reported levels of teacher self-efficacy, collective efficacy, and job satisfaction in special educators, teachers in one school district completed three surveys measuring these constructs. The results indicated that teacher self-efficacy had a direct effect on job satisfaction. It was further found that collective efficacy directly affected teacher self-efficacy but that it did not have a direct effect on job satisfaction. No significant differences were found in reported levels of these areas across subgroups of teachers categorized by teaching level (elementary, middle, and high), teaching setting (self-contained, resource, or inclusion), and certification type (highly qualified, not highly qualified, or emergency).
Adventures in the subatomic universe: An exploratory study of a scientist–museum physics education project

Quarked! ™ is a collaborative education project between physicists, museum educators and designers that was developed to introduce youth to concepts of scale and the particulate nature of matter through hands-on museum programs and a website with animated videos, games and lesson plans. A pilot study was carried out to assess the project’s success in presenting these concepts in a fun and engaging way for an elementary and middle school aged audience, to investigate its relevance to teachers, and to explore children’s awareness of things that they cannot directly see. We found that children as young as second grade are aware of microscopic entities that can be studied indirectly. Our study also suggests that concepts of scale and matter can be presented in a way that is engaging and accessible to youth, and that teachers consider relevant to existing curricula.
Witnessing in crisis: Photo-reportage of terror attacks in Boston and London

The importance of bearing witness to what is transpiring in harrowing circumstances is a lynchpin of war and conflict reporting. More often than not in recent years, however, the person first on the scene with a camera has been an ordinary citizen, if not one of the combatants themselves. Accordingly, this article explores a number of pressing questions confronting news photographers – both professionals of the craft and bystanders offering improvised contributions to newsmaking – committed to relaying what they see unfolding before them, however disturbing it may be. More specifically, the discussion focuses on two crisis events recurrently characterised as ‘terror attacks’ in the US and British press: the bombing of the Boston marathon in April 2013, and the killing of a British soldier in Woolwich, southeast London, the following month. Drawing on a visual analysis of the photo-reportage of these attacks, the author examines diverse forms of citizen witnessing and their potential to reinvigorate photojournalism’s social contract to document conflicting truths.
Synergeyes Versus Soft Toric Lenses: Vision-Related Quality of Life

Purpose. The purpose of this study is to contrast the clinical and vision-related quality of life outcomes between Synergeyes, a hybrid contact lens, and Bausch & Lomb Soflens 66 Toric contact lenses in a cross-over design. Also, to determine subject preference of one mode of lens wear over the other. Methods. The Synergeyes lens has a central rigid gas permeable portion made of Paragon HDS100 material (paflufocon D) bonded to the nonionic hydrophilic skirt material of 27% water (PolyHEMA hem-iberfilcon A). The Soflens 66 Toric lens is made of a nonionic hydrophilic 66% water (alphafilcon A) material. Subjects age 18 years and older with spherical refractive error between −0.50 and −8.00 D and astigmatism correction of −0.75 to −3.50 D were randomly assigned to wear one mode of contact lens for 1 month then wear the alternate mode for 1 month. Follow-up visits were done at 1 and 4 weeks. Data gathered at these visits included high-contrast log MAR distance visual acuity, average wearing time, comfortable wearing time, over-refraction, and slit lamp observations for corneal edema, conjunctival hyperemia, and corneal staining. At each visit, subjects were asked to rate overall comfort, dryness, and comfortable wearing time. Subjects were asked to complete the NEI-RQL-42 questionnaire at the end of each lens wearing period. Upon completion of both lens wearing modes, subjects were asked to choose their preferred mode. Results. Fifty subjects completed the study; 22 (44%) preferred the Synergeyes lenses, and 28 (56%) preferred the Soflens 66 Toric soft lenses. Measured visual acuity was significantly better with the Synergeyes lenses. Of the 13 attributes analyzed in the RQL-42, a statistically significant difference between the two modes was found in only one category, “symptoms. ” In that category, subjects indicated fewer symptoms when wearing soft lenses. The subjects' ratings also showed significantly more comfort while wearing the soft toric lenses. Conclusions. Bausch & Lomb Soflens 66 Toric lenses were more comfortable and were perceived to produce less symptoms of dryness, itchiness, and lens awareness than Synergeyes lenses. Synergeyes lenses gave better visual acuity than the soft toric lenses.
Probabilistic trajectory estimation based leader following for multi-robot systems

The paper is concerned with the multi-robot leader-following problem in the presence of frequent dropouts in vision detection. In many scenarios, for instance a structured environment, it is inevitable to experience outage of vision detection due to reasons such as the target moving out of view, vision occlusion, motion blurring, etc. The paper proposes a Bayesian trajectory estimation based leader-following approach that can offer accurate path following given intermittent vision observations. The follower robot estimates the trajectory of the leader robot based on the noise-corrupted odometry information of both robots, and inter-robot relative observations based on detection of fiducial markers using an RGBD camera. A linear trajectory-following control method is employed to track a historical pose of the leader robot on the estimated trajectory. Results are obtained based on evaluating the proposed leader-following approach in tests with a zig-zag shaped trajectory and with a trajectory that contains sharp turns.
The missing link: Enhanced functional connectivity between amygdala and visceroceptive cortex in migraine

Background Migraine is a neurovascular disorder in which altered functional connectivity between pain-modulating circuits and the limbic system may play a role. Cortical spreading depression (CSD), which underlies migraine aura (MWA), induces C-fos expression in the amygdala. The role of CSD and amygdala connectivity in migraine without aura (MwoA) is less clear and may differentiate migraine from other chronic pain disorders. Methods Using resting-state functional MRI, we compared functional connectivity between the amygdala and the cortex in MWA and MWoA patients as well as in healthy subjects and in two other chronic pain conditions not associated with CSD: trigeminal neuralgia (TGN) and carpal tunnel syndrome (CTS). Results Amygdala connectivity in both MWA and MWoA was increased to the visceroceptive insula relative to all other groups examined. Conclusion The observed increased connectivity within the limbic/viscerosensory network, present only in migraineurs, adds to the evidence of a neurolimbic pain network dysfunction and may reflect repetitive episodes of CSD leading to the development of migraine pain.
Social Loafing in Cheerleaders: Effects of Team Membership and Competition

The group performance literature suggests that when individuals work together on a task, they tend to exert less effort than when they perform the same task individually (Jackson & Williams, 1985). This reduction of individual effort when individuals are collectively held responsible for a task has been termed social loafing (LatanC, Williams, & Harkins, 1979). Social loafing has been demonstrated to occur in a variety of physically effortful tasks such as rope pulling (Ingham, Levinger, Graves, & Peckham, 1974), noise production (Latank et al., 1979), and force production (Kerr & Brunn, 1981). This effect has also been demonstrated for tasks requiring cognitive effort such as evaluation of essays (Petty, Harkins, Williams, & Latan6, 1977), brainstorming, and vigilance (Harkins & Petty, 1982). Moreover, social loafing has been found to characterize the behavior of both males and females of all ages (Harkins, Latant? , & Williams, 1980; LatanC, 1986), in betweenas well as within-subjects designs (Harkins et al., 1980; Kerr & B r u ~ , 1981), and in both individualistic and collective cultures (LatanC, 1986). Thus, social loafing appears to be a rather robust phenomenon, threatening effective collective endeavor. However, several factors have been identified that appear to moderate the magnitude of this effect. Specifically, loafing was eliminated when individual efforts were identifiable (Williams, Harkins, & Latank, 1981), when individuals perceived that they made a unique contribution to the group effort or performed difficult tasks (Harkins & Petty, 1982), when individuals performed with friends versus strangers (Williams, 1981), when conjunctive and disjunctive tasks were employed (Kerr, 1983), and when the task was personally involving (Brickner, Harkins, & Ostrom, 1986). However, the research conditions of many of these investigations created motivational properties that appear to be in opposition to those associated with established teams performing a team-related task under competitive conditions. That is, social loafing may be restricted to tasks that are seen as unimportant, meaningless, or lacking in intrinsic motivation, performed by relative strangers in noncompetitive contexts. The purpose of this study, therefore, was to investigate social loafing among established teams performing an intrinsically motivating team-related task under competitive conditions.
Interaction between Marine-Derived n-3 Long Chain Polyunsaturated Fatty Acids and Uric Acid on Glucose Metabolism and Risk of Type 2 Diabetes Mellitus: A Case-Control Study

The present case-control study explored the interaction between marine-derived n-3 long chain polyunsaturated fatty acids (n-3 LC PUFAs) and uric acid (UA) on glucose metabolism and risk of type 2 diabetes mellitus (T2DM). Two hundred and eleven healthy subjects in control group and 268 T2DM subjects in case group were included. Plasma phospholipid (PL) fatty acids and biochemical parameters were detected by standard methods. Plasma PL C22:6n-3 was significantly lower in case group than in control group, and was negatively correlated with fasting glucose (r = −0.177, p < 0.001). Higher plasma PL C22:6n-3 was associated with lower risk of T2DM, and the OR was 0.32 (95% confidence interval (CI), 0.12 to 0.80; p = 0.016) for per unit increase of C22:6n-3. UA was significantly lower in case group than in control group. UA was positively correlated with fasting glucose in healthy subjects, but this correlation became negative in T2DM subjects. A significant interaction was observed between C22:6n-3 and UA on fasting glucose (p for interaction = 0.005): the lowering effect of C22:6n-3 was only significant in subjects with a lower level of UA. In conclusion, C22:6n-3 interacts with UA to modulate glucose metabolism.
G 2 and M phases ( all active phases of cell cycle ) but not in G 0 phase ( resting cells

Oral mucocutaneous diseases (a heterogeneous group of disorders) could involve skin and mucous membranes as one of the most common of them is oral lichen planus (OLP) frequently found in patients visiting dental clinics (Jaafari-Ashkavandi et al., 2011; Lin et al., 2011; Gorugantula et al., 2012). OLP is a chronic inflammatory and T cell-mediated autoimmune disease related to stratified squamous epithelia having a wide range of clinical manifestations (Roopashree et al., 2010; Georgakopoulou et al., 2012). Its prevalence is about 1 to 2% among adults who are 40 years old or elder mostly occurring during the 6th decade of life with an approximate ratio of 1.4 to 1 for women to men (Roopashree et al., 2010; García-García et al., 2012). This chronic inflammatory oral mucosal disease has also been considered as a potential precancerous disorder (de Sousa et al., 2009a ;García-García et al., 2012). It was suggested that patients with OLP are at risk of developing oral squamous cell carcinoma (OSCC) although actual malignant transformation potential of OLP remains a
Pushing the Envelope: Extreme Network Coding on the GPU

While it is well known that network coding achieves optimal flow rates in multicast sessions, its potential for practical use has remained to be a question, due to its high computational complexity. With GPU computing gaining momentum as a result of increased hardware capabilities and improved programmability, we show in this paper how the GPU can be used to improve network coding performance dramatically. Our previous work presented the first attempt in the literature to maximize the performance of network coding by taking advantage of not only multi-core CPUs, but also hundreds of computing cores in commodity off-the-shelf Graphics Processing Units (GPU). This paper represents another step forward, and presents a new array of GPU-based algorithms that improve network encoding by a factor of 2.2, and network decoding by a factor of 2.7 to 27.6 across a range of practical configurations. With just a single NVIDIA GTX 280 GPU, our implementation of GPU-based network encoding outperforms an 8-core Intel Xeon server by a margin of at least 4.3 to 1 in all practical test cases, and over 3000 peers can be served at high-quality video rates if network coding is used in a streaming server. With 128 blocks, for example, coding rates up to 294 MB/second can be achieved with a variety of block sizes.
The eye of the beholder: authenticity in an embedded assessment task

Authenticity is now firmly established as a central concern in test design and test validation (Bachman, 1990). However, there is disagreement about what authenticity is and about the degree of authenticity that can realistically be achieved. This article explores the theoretical and practical issues surrounding authenticity in course-based assessment, drawing on data from a university-level Japanese language course in Australia. It examines a teaching and assessment activity based around interviewing native speakers outside the classroom, which was designed to optimize authenticity. Using tapes that students made of the interview for assessment and retrospective interviews, the study examines various dimensions of authenticity and reveals a wide diversity in individual experiences. The article argues that the addition of an assessment dimension fundamentally changes the nature of a task, and thus compromises authenticity. It further suggests that authenticity must be viewed in terms of the implementation of an activity, not its design, and examines the various factors that affect the degree of authenticity experienced by individual students. The implications of this diversity for the validity of the activity are discussed.
Does good emotion management aid forgiving? Multiple dimensions of empathy, emotion management and forgiveness of self and others

The ability to forgive is considered important in the successful maintenance of relationships. In this study, a multifactorial model predicting two forms of forgiveness was examined in a combined community and university sample (N = 110) who reported on their ability to manage emotions, their tendency to empathize (through perspective taking, empathic concern, and personal distress), and their disposition to forgive others and self. Findings suggested that the ability to manage and repair emotions predicted a greater disposition to forgive, and that perspective taking mediated the relationship between emotion management and forgiveness of others. A multifactorial model for other-forgiveness was completely replicated in significant others' (N = 104) reports about participants, although significant others' results only partially replicated participant findings for self-forgiveness.
SPANISH VALIDATION OF THE LOCUS OF CONTROL QUESTIONNAIRE IN SPORT FOR CHILDREN VALIDACIÓN ESPAÑOLA DEL CUESTIONARIO DE LOCUS DE CONTROL EN DEPORTE INFANTIL

Locus of control has been studied in the sporting context, however a valid assessment instrument in children's sports has not existed. This study adapts into Spanish and validates the Children's Sport Locus of Control Scale (CSLCS) in the Spanish language. The CSLCS was developed by Tsai and Hsieh (2015). The adaptation has two phases: an initial screening of 248 children between the ages of 7 and 16 to observe the qualitative behavior of the items; and a second one with 221 athletes with children between the ages of 8 and 22 in which the questionnaire was modified to fit the results. A final 10-item scale was obtained, with 5 items per dimension (internal and external), which presents an adequate fit. Results show that the Spanish version of the scale possesses adequate psychometric qualities for its use in research and applied fields in child ́s sport evaluation.
New design methodology for MEMS-electronic-package co-design and validation for inertial sensor systems

This paper proposes a new design methodology enabling the co-design of MEMS with electronics while considering the influences of its surrounding package. The proposed solution has been validated on a case study of a MEMS accelerometer. We describe different options to simulate the MEMS accelerometer device with its package. Firstly, as a parametric MEMS+ component model based on high-order finite elements. Secondly, as an automatically generated reduced-order model in VerilogA format. Both models are fully compatible with standard electronic circuit simulators. The comparison between both models reveals that the VerilogA model shows similar accuracy (difference is smaller than 1%) while it is considerably faster in simulation time (by more than a factor of 1000). The proposed methodology can efficiently simulate the interaction between MEMS chip, package and electronic read-out circuit, which is an important part of a new approach of smart system design.
