Relation Analysis in eLearning

The science of networks is experiencing a rapid expansion. Over the past several years, the disclosure of large amount of information which can be extracted from linked web pages or various Internet-based databases has led to an explosion of network research. This discipline has expanded into the spheres of all human activities. The work is oriented to the social network field. Relations between the objects in common social networks are defined directly. Authors researched a set of the data from the learning management system Moodle. The community obtained has different characteristic features from other common social networks. Every communication and interactions among the students (network objects) is realized through the Moodle system. The authors attempted to find whether in such specific environment can originate any form of social network and whether this network has typical characteristics of social networks. The results are demonstrated using graph representation.
Spherical solid dispersion containing amorphous tolbutamide embedded in enteric coating polymers or colloidal silica prepared by spray-drying technique.

Spherical solid dispersion particles of tolbutamide were prepared by spray-drying a diluted ammonia solution of the drug with additives. Enteric coating polymers (Eudragit R L100-55, hydroxypropyl methylcellulose phthalate) and colloidal silica (Aerosil R) were useful as additives for the solid dispersions. Most of the tolbutamide was dispersed in the amorphous state in the solid dispersion particles when the drug and the additive were formulated in the ratio of 1: 1. It was a characteristic of the spray-dried solid dispersions that the additive content was smaller than that of dispersions prepared by conventional solvent evaporation or by a grinding method. The drug dissolution in vitro was investigated using the disintegration solution No. 2 (pH 6.8) specified in JP X. The dissolution rate from the solid dispersions was markedly improved compared with that from the original or spray-dried drug powder. The rapid dissolution rate from the solid dispersion with enteric coating polymers was attributed to improved wettability and rapid dissolution of the polymer, while that from the dispersion with colloidal silica was found to have a close relationship with the drug crystallinity as well as the wettability.
Racial Categorization and Stereotype-Based Judgments About Homeless People1

The present study uses a social-cognitive paradigm to examine the association between racial categorization and stereotype-based judgments about homeless people. The study uses data from a national White subsample (N= 1,221) surveyed about attitudes toward homeless/homeless mentally ill people. It was hypothesized that individual differences in perceptions of the representativeness of Blacks in the homeless population, as measured by subjective estimates of the percentage of Blacks, would be associated with the enhancement of racially relevant negative stereotypes about homeless people. A secondary hypothesis was that perceptions of the representativeness of Blacks would be more strongly associated with the stereotype of homeless people as dangerous than with the view of them as lazy. The results support these hypotheses.

competencies. Finally, Eunice Boardman’s cautionary coda sums up ’the issues that will if we can solve them perhaps help us avoid having to look back in 2021 and admit that we are still fighting the same windmills’ (p. 279). Essentially, her Message for the Teacher of Teachers is a plea for the adoption of more integrative and holistic approaches to the undergraduate programme which will provide opportunities for aesthetic experiences and discovery learning situations in all aspects of the
Analysis of Epithelial Growth Factor-Receptor (EGFR) Phosphorylation in Uterine Smooth Muscle Tumors: Correlation to Mucin-1 and Galectin-3 Expression

Uterine fibroids are the commonest uterine benign tumors. A potential mechanism of malignant transformation from leiomyomas to leiomyosarcomas has been described. Tyrosine phosphorylation is a key mechanism that controls biological functions, such as proliferation and cell differentiation. The aim of the current study was to evaluate the phosphorylation of epithelial growth factor-receptor (EGFR) in normal myometrium, uterine myomas and uterine leiomyosarcomas. Formalin-fixed paraffin-embedded tissue samples from normal myometrium, leiomyomas and leiomyosarcomas were studied. Samples were immunohistochemically (IHC) assessed using the anti-EGFR phosphorylation of Y845 (pEGFR-Y845) and anti-pEGFR-Y1173 phosphorylation-specific antibodies. IHC staining was evaluated using a semiquantitative score. The expression of pEGFR-Y845 was significantly upregulated in leiomyosarcomas (p < 0.001) compared to leiomyomas and normal myometrium. In contrast, pEGFR-Y1173 did not differ significantly between the three groups of the study. Correlation analysis revealed an overall positive correlation between pEGFR Y845 and mucin 1 (MUC1). Further subgroup analysis within the tumoral group (myomas and leiomyosarcomas) revealed an additional negative correlation between pEGFR Y845 and galectin-3 (gal-3) staining. On the contrary no significant correlation was noted within the non-tumoral group. An upregulated EGFR phosphorylation of Y845 in leiomyosarcomas compared to leiomyomas implicates EGFR activation at this special receptor site. Due to these pEGFR-Y845 variations, it can be postulated that MUC1 interacts with it, whereas gal-3 seems to be cleaved from Y845 phosphorylated EGFR. Further research on this field could focus on differences in EGFR pathways as a potentially advantageous diagnostic tool for investigation of benign and malignant signal transduction processes.
Temporal and Spatial Features of Single-Trial EEG for Brain-Computer Interface

Brain-computer interface (BCI) systems create a novel communication channel from the brain to an output device bypassing conventional motor output pathways of nerves and muscles. Modern BCI technology is essentially based on techniques for the classification of single-trial brain signals. With respect to the topographic patterns of brain rhythm modulations, the common spatial patterns (CSPs) algorithm has been proven to be very useful to produce subject-specific and discriminative spatial filters; but it didn't consider temporal structures of event-related potentials which may be very important for single-trial EEG classification. In this paper, we propose a new framework of feature extraction for classification of hand movement imagery EEG. Computer simulations on real experimental data indicate that independent residual analysis (IRA) method can provide efficient temporal features. Combining IRA features with the CSP method, we obtain the optimal spatial and temporal features with which we achieve the best classification rate. The high classification rate indicates that the proposed method is promising for an EEG-based brain-computer interface.
Survey On Scheduling And Radio Resources Allocation In Lte

This paper focuses on an essential task of the enhanced NodeB eNodeB element in LTE architecture, the Radio Resource Manager RRM, which aims to accept or reject requests for connection to the network based on some constraints and ensuring optimal distribution of radio resources between Users Equipments UEs. Its main functionalities include Admission Control AC and Packet Scheduling PS. This paper will center mainly on the PS part of the RRM task, which performs the radio resource allocation in both uplink and downlink directions. Several approaches and algorithms have been proposed in the literature to address this need ie : allocate resources efficiently, the diversity and multitude of algorithms is related to the factors considered for the optimal management of radio resource, specifically, the traffic type and the QoS Quality of Service requested by the UE. In this article, an art's state of the radio resource allocation strategies and a detailed study of several scheduling algorithms proposed for LTE (uplink and downlink) are made. Therefore, we offer our evaluation and criticism.
Joint Adaptive Sparsity and Low-Rankness on the Fly: An Online Tensor Reconstruction Scheme for Video Denoising

Recent works on adaptive sparse and low-rank signal modeling have demonstrated their usefulness, especially in image/video processing applications. While a patch-based sparse model imposes local structure, low-rankness of the grouped patches exploits non-local correlation. Applying either approach alone usually limits performance in various low-level vision tasks. In this work, we propose a novel video denoising method, based on an online tensor reconstruction scheme with a joint adaptive sparse and lowrank model, dubbed SALT. An efficient and unsupervised online unitary sparsifying transform learning method is introduced to impose adaptive sparsity on the fly. We develop an efficient 3D spatio-temporal data reconstruction framework based on the proposed online learning method, which exhibits low latency and can potentially handle streaming videos. To the best of our knowledge, this is the first work that combines adaptive sparsity and low-rankness for video denoising, and the first work of solving the proposed problem in an online fashion. We demonstrate video denoising results over commonly used videos from public datasets. Numerical experiments show that the proposed video denoising method outperforms competing methods.
Functional synergy between the Munc13 C-terminal C1 and C2 domains

Neurotransmitter release requires SNARE complexes to bring membranes together, NSF-SNAPs to recycle the SNAREs, Munc18-1 and Munc13s to orchestrate SNARE complex assembly, and Synaptotagmin-1 to trigger fast Ca2+-dependent membrane fusion. However, it is unclear whether Munc13s function upstream and/or downstream of SNARE complex assembly, and how the actions of their multiple domains are integrated. Reconstitution, liposome-clustering and electrophysiological experiments now reveal a functional synergy between the C1, C2B and C2C domains of Munc13-1, indicating that these domains help bridging the vesicle and plasma membranes to facilitate stimulation of SNARE complex assembly by the Munc13-1 MUN domain. Our reconstitution data also suggest that Munc18-1, Munc13-1, NSF, αSNAP and the SNAREs are critical to form a ‘primed’ state that does not fuse but is ready for fast fusion upon Ca2+ influx. Overall, our results support a model whereby the multiple domains of Munc13s cooperate to coordinate synaptic vesicle docking, priming and fusion. DOI: http://dx.doi. org/10.7554/eLife.13696. 001
University students’ perceptions of a fair learning environment: a social justice perspective

This study aimed to identify the manner in which university students construe ‘fair treatment’ and how justice related processes are perceived to influence students’ psychological identification with their academic department. In the first study, 342 undergraduate psychology students completed two questionnaires: one measured various aspects of interpersonal, procedural and outcome fairness in their department, and the other measured their level of psychological identification with the department. Students construed the fairness of their learning environment in terms of two conceptually distinct justice factors: respectful partnership between staff and students reflecting primarily interpersonal justice considerations; and systemic fairness reflecting a concern for accessible information and effective problem‐solving procedures. Hierarchical regression analyses indicated that although both justice factors significantly influenced students’ psychological identification with their department, interactional justice concerns (i.e., respectful staff–student partnership) were most strongly predictive. In the second study (n = 87), students’ perceptions of fairness were found to share substantial variance with their ratings on the good teaching and clear goals scales of the Course Experience Questionnaire.
RPP: reference pattern based prefetching controller

We propose a prefetching technique that recognizes and exploits reference patterns. Reference Pattern based Prefetching (RPP) detects sequential and non-sequential reference patterns and takes different prefetch action according to this information. Beyond sequential detection, RPP recognizes repetitive occurences of consecutive sequences, and then exploits these repetitions. In this paper, we show that RPP results in favorable performance gains.
Percentage discounts, initial price, and bargain hunting : a heuristic-systematic approach to price search behavior

Consumer decisions concerning price search were investigated using the heuristic-systematic model of social judgment (S. Chaiken, A. Liberman, & A. H. Eagly, 1989 ). Consumers used the size of the percentage discount as a heuristic cue to help decide whether a better price was likely to be available elsewhere. However, as predicted, participants relied on this cue only when the initial base price of the item was low. In contrast, search was continued despite the offer ofa large percentage discount when consumers were shopping for items that were relatively expensive. This finding was attributed to the higher potential costs associated with missing a better price when consumers were shopping for more expensive items. In general, the heuristic-systematic model proved to be a useful way to characterize price search decisions. It was also suggested that these findings might be useful in explaining some conflicting results in the price search literature. Implications for behavioral price theories are also discussed.
Are security and privacy equally important in influencing citizens to use e–consultation?

This paper investigates the importance of two factors: security and privacy in e–government based on the e–consultation aspect of government–to–citizen (G2C) interaction. Prior research on what factors influence citizens in using e–government has focused mainly at the personal level e.g., security, ease of use, usefulness, etc. The advent of information and communication technology (ICT) particularly the web 2.0 technology makes citizens sharing common interest to communicate with one another, suggesting bigger voice or speak of higher volume when dealing with government agencies. Therefore, it is important to investigate what other factors contribute to citizens to use e–government application especially at the community level. From a socio–technical design perspective, this paper proposes an e–government framework that reflects G2C interaction by introducing privacy as a community factor of an e–government application in addition to security as a personal factor. Results suggest privacy is rated slightly more important compared to security in influencing citizens to use e–consultation.
Precise Medication Extraction using Agile Text Mining

Agile text mining is widely used for commercial text mining in the pharmaceutical industry. It can be applied without building an annotated training corpus, so is well-suited to novel or one-off extraction tasks. In this work we wanted to see how efficiently it could be adapted for healthcare extraction tasks such as medication extraction. The aim was to identify medication names, associated dosage, route of administration, frequency, duration and reason, as specified in the 2009 i2b2 medication challenge. Queries were constructed based on 696 discharge summaries available as training data. Performance was measured on a test dataset of 251 unseen
Does the evocation of traumatic memories confound subsequent working memory performance in posttraumatic stress disorder (PTSD)?

The role of heightened arousal has been previously discussed as a contributor to neurocognitive impairment in posttraumatic stress disorder (PTSD). To investigate whether psychological effects (distraction, re‐location of resources) elicited by the evocation of traumatic memories impact on subsequent cognitive performance in PTSD, two parallel versions of a working memory task were administered to 33 trauma‐exposed participants (15 with and 18 without PTSD). Between first and second working memory assessment a trauma‐related interview was conducted including the narration of the trauma. Levels of working memory impairment in PTSD patients remained unchanged. This study provides preliminary evidence that neurocognitive impairment is not secondary to psychological effects induced by the evocation of traumatic memories. Nevertheless, it is recommended that future PTSD research should devote more care to the order in which trauma‐related and other dependent variables such as cognitive tests are presented to participants.

Salivary Testosterone Levels and Health Status in Men and Women in the British General Population: Findings from the Third National Survey of Sexual Attitudes and Lifestyles (Natsal-3)

Context: Salivary T (Sal-T) measurement by liquid chromatography–tandem mass spectroscopy resents the opportunity to examine health correlates of Sal-T in a large-scale population survey. Objective: This study sought to examine associations between Sal-T and health-related factors in men and women age 18–74 years. Design and Setting: Morning saliva samples were obtained from participants in a cross-sectional probability-sample survey of the general British population (Natsal-3). Self-reported health and lifestyle questions were administered as part of a wider sexual health interview. Participants: Study participants included 1599 men and 2123 women. Methods: Sal-T was measured using liquid chromatography–tandem mass spectroscopy. Linear regression was used to examine associations between health factors and mean Sal-T. Results: In men, mean Sal-T was associated with a range of health factors after age adjustment, and showed a strong independent negative association with body mass index (BMI) in multivariable analysis. Men reporting cardiovascular disease or currently taking medication for depression had lower age-adjusted Sal-T, although there was no association with cardiovascular disease after adjustment for BMI. The decline in Sal-T with increasing age remained after adjustment for health-related factors. In women, Sal-T declined with increasing age; however, there were no age-independent associations with health-related factors or specific heath conditions with the exception of higher Sal-T in smokers. Conclusions: Sal-T levels were associated, independently of age, with a range of self-reported health markers, particularly BMI, in men but not women. The findings support the view that there is an age-related decline in Sal-T in men and women, which cannot be explained by an increase in ill health. Our results demonstrate the potential of Sal-T as a convenient measure of tissue androgen exposure for population research.
An integrated approach (CLuster Analysis Integration Method) to combine expression data and protein-protein interaction networks in agrigenomics: application on Arabidopsis thaliana.

Experimental co-expression data and protein-protein interaction networks are frequently used to analyze the interactions among genes or proteins. Recent studies have investigated methods to integrate these two sources of information. We propose a new method to integrate co-expression data obtained through DNA microarray analysis (MA) and protein-protein interaction (PPI) network data, and apply it to Arabidopsis thaliana. The proposed method identifies small subsets of highly interacting proteins. Based on the analysis of the basis of co-localization and mRNA developmental expression, we show that these groups provide important biological insights; additionally, these subsets are significantly enriched with respect to KEGG Pathways and can be used to predict successfully whether proteins belong to known pathways. Thus, the method is able to provide relevant biological information and support the functional identification of complex genetic traits of economic value in plant agrigenomics research. The method has been implemented in a prototype software tool named CLAIM (CLuster Analysis Integration Method) and can be downloaded from http://bio.cs. put.poznan. pl/research_fields . CLAIM is based on the separate clustering of MA and PPI data; the clusters are merged in a special graph; cliques of this graph are subsets of strongly connected proteins. The proposed method was successfully compared with existing methods. CLAIM appears to be a useful semi-automated tool for protein functional analysis and warrants further evaluation in agrigenomics research.
A recessive gene controlling male sterility sensitive to short daylength/low temperature in wheat (Triticum aestivum L.)

Utilization of a two-line breeding system via photoperiod-thermo sensitive male sterility has a great potential for hybrid production in wheat (Triticum aestivum L.). 337S is a novel wheat male sterile line sensitive to both short daylength/low temperature and long daylength/high temperature. Five F2 populations derived from the crosses between 337S and five common wheat varieties were developed for genetic analysis. All F1’s were highly fertile while segregation occurred in the F2 populations with a ratio of 3 fertile:1 sterile under short daylength/low temperature. It is shown that male sterility in 337S was controlled by a single recessive gene, temporarily designated as wptms3. Bulked segregant analysis (BSA) coupled with simple sequence repeat (SSR) markers was applied to map the sterile gene using one mapping population. The wptms3 gene was mapped to chromosome arm 1BS and flanked by Xgwm413 and Xgwm182 at a genetic distance of 3.2 and 23.5 cM, respectively. The accuracy and efficiency of marker-assisted selection were evaluated and proved essential for identifying homozygous recessive male sterile genotypes of the wptms3 gene in F2 generation.
Low-resource ECDSA implementation for passive RFID tags

With the introduction of security functionality RFID is an emerging technology that has high potential in numerous of applications. In this paper we investigate the hardware implementation of public-key cryptography for passive RFID tags. We generate digital signatures according to the ECDSA algorithm for authentication of RFID tags in open-loop scenarios. The implementation of ECDSA is based on the recommended Fp160 SECG elliptic curve SECP160r1. In order to meet the fierce constraints concerning power consumption and chip area our design has a 16-bit word size. The hardware module consists of a latch based 90×16-bit dual-port RAM, a datapath with a 16×16-bit multiply-accumulate unit and a dedicated finite-state machine. The design requires a chip area of 18 247 GEs and has a power consumption of 860 µW at 1MHz using a 0.35 µm CMOS technology. In total, an ECDSA signature requires 511 864 clock cycles.
