PROMOTING SCHOLARSHIP THROUGH DESIGN

How can new media positively transform scholarly practices? One possible way is for scholarly archives such as e-journals and digital libraries to better support the needs and practices of their users, instead of the publishing process. This article examines what it might mean to promote cognitive and social aspects of 'scholarship' through innovative archive design. Design requirements for supporting both scholarly tasks and scholarly communities are derived by analysing existing cognitive and social theories. A theoretical framework for guiding archive design is introduced: the contextually enriched document framework. This framework suggests that: document interfaces should enable practitioners to progressively enrich documents with important contextual information arising from social processes; and archive managers should engage in proactive practices to facilitate use and assist practitioners in realizing the benefits of the new technology. Both the design requirements and the framework are illustrated with examples from an existing electronic journal - The Journal of Interactive Media in Education .
A Note on Bayesian Learning and Identi ability in Hierarchical Models

Identi ability has long been an important concept in classical statistical estimation Historically Bayesians have been less interested in the concept since strictly speaking any parameter having a proper prior distribution is estimable However the larger statistical community s recent move toward more Bayesian thinking is largely fueled by an interest in Markov chain Monte Carlo based analyses using vague or even improper priors As such Bayesians have been forced to think more carefully about what has been learned about the parameters of interest given the data so far or what could possibly be learned given an in nite amount of data In this paper we propose measures of Bayesian learning based on di erences in precision and Kullback Leibler divergence After investigating them in the context of some familiar Gaussian linear hierarchical models we consider their use in a more challenging setting involving two sets of random e ects traditional and spatially arranged only the sum of which is identi ed by the data We illustrate this latter model with an example from periodontal data analysis where the spatial aspect arises from the proximity of various measurements taken in the mouth Our results suggest our measures behave sensibly and may be useful in even more complicated e g non Gaussian model settings
Multilevel direct DFB phase modulation in 6.25 GHz spectrally spaced UDWDM PONs

Direct phase modulation of DFB is demonstrated with DPSK, DQPSK and Duobinary modulation formats and detected with an intradyne receiver based on a 120-degree hybrid. The system is tested in a 50 km fibre link with 6.25 GHz channel spacing among users in a UDWDM-PON. By using higher modulation formats, the spectral efficiency can be increased in a single carrier system without spectral shaping while achieving an Rx sensitivity of -40 dBm at BER = 10-3 for 5 Gb/s in a 2 GHz bandwidth limited DFB.
Electromyostimulation training effects on neural drive and muscle architecture.

PURPOSE The purpose of the study was to investigate the effect of 4 and 8 wk of electromyostimulation (EMS) training on both muscular and neural adaptations of the knee extensor muscles. METHODS Twenty males were divided into the electrostimulated group (EG, N = 12) and the control group (CG, N = 8). The training program consisted of 32 sessions of isometric EMS over an 8-wk period. All subjects were tested at baseline (B) and retested after 4 (WK4) and 8 (WK8) wk of EMS training. The EMG activity and muscle activation obtained under maximal voluntary contractions (MVC) was used to assess neural adaptations. Torque and EMG responses obtained under electrically evoked contractions, muscle anatomical cross-sectional area (ACSA), and vastus lateralis (VL) pennation angle, both measured by ultrasonography imaging, were examined to analyze muscular changes. RESULTS At WK8, knee extensor MVC significantly increased by 27% (P < 0.001) and was accompanied by an increase in muscle activation (+6%, P < 0.01), quadriceps muscle ACSA (+6%, P < 0.001), and VL pennation angle (+14%, P < 0.001). A significant increase in normalized EMG activity of both VL and vastus medialis (VM) muscles (+69 and +39%, respectively, P < 0.001) but not of rectus femoris (RF) muscle was also found at WK8. The ACSA of the VL, VM, and vastus intermedius muscles significantly increased at WK8 (5-8%, P < 0.001) but not at WK4, whereas no changes occurred in the RF muscle. CONCLUSION We concluded that the voluntary torque gains obtained after EMS training could be attributed to both muscular and neural adaptations. Both changes selectively involved the monoarticular vastii muscles.
An optimized fingerprinting system for tamper proof and copy control of XML documents

Today, with the fast development of Extensible Markup Language (XML) and increasing amount of data that is published in the form of XML, copyright protection of these data is becoming an important requirement for numerous applications. This study is proposing a system that uses fingerprinting to trace illegal copies and detect any modification made to an XML data. However, the flexible construction of XML data poses a number of challenges to fingerprinting, such as reorganization and alteration. To overcome these challenges, the proposed system has to be based on the winnowing theory, which selects fingerprints from hashes of XML elements. This system is effective to make less distortion to the original data and to preserve usability constraints. Experimental results show that the probability of missing fingerprint detection is very low and the chance to locate changes in the XML data is very high.
Key Exchange Protocol in the Trusted Data Servers Context

The aim of this technical report is to complement the work in [To et al. 2014] by proposing a Group Key Exchange protocol so that the Querier and TDSs (and TDSs themselves) can securely create and exchange the shared key. Then, the security of this protocol is formally proved using the game-based model. Finally, we perform the comparison between this protocol and other related works.
Continuous measurement of emotion: The affect rating dial.

Measurement of an individual's subjective experience of emotion has long been a key component of emotion research, but it presents some unique challenges. Researchers have developed a number of different methods to assess the subjective emotional experiences of study participants, each of which has its strengths and limitations. Self-report measures such as the Positive and Negative Affect Schedule (PANAS; Watson, Clark, &: Tellegen, 1988) are well established and easy to complete and provide useful information; however, administration of any written measure necessitates an interruption in the flow of an experiment and does not allow frequent or continuous sampling of affective states. More involved methods, such as interviewing, give a detailed and comprehensive picture of a person's emotions, but they are time-consuming and can provide only a retrospective report of affect. The interactive computer version of the Self-Assessment Manikin (SAM) Scales (Bradley &: Lang, 1994) allows online assessment of both emotional valence and arousal levels, but it, too, does not provide a continuous record of affect. The affect rating dial is an assessment method that was developed to measure self-reported emotion continuously in social interaction. It is unique among subjective measures of affect in allowing the measurement of the time course of an emotional experience and generating continuous data that can be viewed both normatively and ideographically. This chapter outlines the development of the affect rating dial, its
A Curious Truncation of N=4 Yang-Mills

The coupling constant dependence of correlation functions of BPS operators in N=4 Yang-Mills can be expressed in terms of integrated correlation functions. We approximate these integrated correlators by using a truncated OPE expansion. This leads to differential equations for the coupling dependence. When applied to a particular sixteen point correlator, the coupling dependence we find agrees with the corresponding amplitude computed via the AdS/CFT correspondence. We conjecture that this truncation becomes exact in the large N and large ’t Hooft coupling limit.
A framework for building multilingual ontologies for Islamic portal

In recent years, there were a variety of difficulties that users have to face in searching for information through Internet. Past research had shown that in performing searches, users use query terms that consist of “everyday language, technical terms (with or without knowledge of underlying concepts) and various explanatory model, all influenced by psychosocial and cultural variations. Semantically annotated documents provide several advantages. One advantage is document specific representations no longer affect the search. This is extremely important in the case of multilingual representations. Keywords of several languages are mapped to the same concept in an ontology and are therefore given the same meaning. Multilingual search portal can be established to produce the same results, no matter which language is used for retrieval. This research aim to identify and analyze ontology that relates to Islam to enhance the use of exact vocabularies and to develop an ontology based Islamic semantic retrieval that can retrieve Islamic web in 3 different languages simultaneously through a multilingual search portal. This research emphasizes on semantic web technologies and the development of ontology using thesaurus such as Library Congress Subject Heading and other reference sources such as Index Islamicus, thesaurus, encyclopaedia, biographies etc. as the basis for implementing novel mechanism for retrieving Islamic web in 3 different languages simultaneously. In this research, existing knowledge sources such as documents, reports, etc. are mapped into the domain ontology and semantically enriched. This semantically enriched information enables better knowledge indexing and searching process and implicitly a better management of knowledge.
Grading nuclear pleomorphism on histological micrographs

A mainstay in cancer diagnostics is the classification or grading of cell nuclei based on their appearance. While the analysis of cytological samples has been automated successfully for a long time, the complexity of histological tissue samples has prevented a reliable classification with machine vision techniques. We approach this complex problem in multiple stages, analyzing first image quality, staining quality, and tissue appearance, before segmenting nuclei and finally classifying or grading areas of tissue. The key step is the training of a classifier to judge the nuclei segmentation quality. Using active learning techniques, we train this classifier to identify problems in the image as well as weaknesses of the image analysis tools. This way we obtain robust nuclear segmentation allowing precise measurements of features that can be used safely for classification. We validate our findings on several hundred cases of breast cancer, demonstrating that automatic pleomorphism grading is possible with high accuracy. This technique can provide a stable and objective basis for what has been a subjective process that suffers from low reproducibility.
Gene expression profiling in bladder cancer identifies potential therapeutic targets

Despite advances in management, bladder cancer remains a major cause of cancer related complications. Characterisation of gene expression patterns in bladder cancer allows the identification of pathways involved in its pathogenesis, and may stimulate the development of novel therapies targeting these pathways. Between 2004 and 2005, cystoscopic bladder biopsies were obtained from 19 patients and 11 controls. These were subjected to whole transcript-based microarray analysis. Unsupervised hierarchical clustering was used to identify samples with similar expression profiles. Hypergeometric analysis was used to identify canonical pathways and curated networks having statistically significant enrichment of differentially expressed genes. Osteopontin (OPN) expression was validated by immunohistochemistry. Hierarchical clustering defined signatures, which differentiated between cancer and healthy tissue, muscle-invasive or non-muscle invasive cancer and healthy tissue, grade 1 and grade 3. Pathways associated with cell cycle and proliferation were markedly upregulated in muscle-invasive and grade 3 cancers. Genes associated with the classical complement pathway were downregulated in non-muscle invasive cancer. Osteopontin was markedly overexpressed in invasive cancer compared to healthy tissue. The present study contributes to a growing body of work on gene expression signatures in bladder cancer. The data support an important role for osteopontin in bladder cancer, and identify several pathways worthy of further investigation.
Kernel Collaborative Representation With Tikhonov Regularization for Hyperspectral Image Classification

In this letter, kernel collaborative representation with Tikhonov regularization (KCRT) is proposed for hyperspectral image classification. The original data is projected into a high-dimensional kernel space by using a nonlinear mapping function to improve the class separability. Moreover, spatial information at neighboring locations is incorporated in the kernel space. Experimental results on two hyperspectral data prove that our proposed technique outperforms the traditional support vector machines with composite kernels and other state-of-the-art classifiers, such as kernel sparse representation classifier and kernel collaborative representation classifier.
Displayed Uncertainty Improves Driving Experience and Behavior: The Case of Range Anxiety in an Electric Car

We explore the impact of the displayed precision of instrumentation estimates of range and state-of-charge on drivers' attitudes towards an all-electric vehicle (EV), on their driving experience, and driving behavior under varying conditions of resource availability. Participants (N=73) completed a 19-mile long drive through highway, rural town and mountain road conditions in an EV that displayed high vs. low remaining range, and gave estimates of that range with high and low information ambiguity. We found that an ambiguous display of range preserved drivers' feelings of trust towards the vehicle, despite encountering situations intended to induce severe range anxiety. Furthermore, compared to drivers facing an unambiguous display of range, drivers presented with an ambiguous range display reported improved driving experience, and exhibited driving behavior better adapted to road and remaining range conditions.
Effective Alu Repeat Based RT-Qpcr Normalization in Cancer Cell Perturbation Experiments

Background Measuring messenger RNA (mRNA) levels using the reverse transcription quantitative polymerase chain reaction (RT-qPCR) is common practice in many laboratories. A specific set of mRNAs as internal control reference genes is considered as the preferred strategy to normalize RT-qPCR data. Proper selection of reference genes is a critical issue, especially in cancer cells that are subjected to different in vitro manipulations. These manipulations may result in dramatic alterations in gene expression levels, even of assumed reference genes. In this study, we evaluated the expression levels of 11 commonly used reference genes as internal controls for normalization of 19 experiments that include neuroblastoma, T-ALL, melanoma, breast cancer, non small cell lung cancer (NSCL), acute myeloid leukemia (AML), prostate cancer, colorectal cancer, and cervical cancer cell lines subjected to various perturbations. Results The geNorm algorithm in the software package qbase+ was used to rank the candidate reference genes according to their expression stability. We observed that the stability of most of the candidate reference genes varies greatly in perturbation experiments. Expressed Alu repeats show relatively stable expression regardless of experimental condition. These Alu repeats are ranked among the best reference assays in all perturbation experiments and display acceptable average expression stability values (M<0.5). Conclusions We propose the use of Alu repeats as a reference assay when performing cancer cell perturbation experiments.

Stabilization of infinitesimally rigid formations of multi-robot networks

This paper proposes a local gradient control law to stabilize a group of robots to a target formation. The control is derived from a potential function based on an undirected infinitesimally rigid graph that specifies the target formation. It is shown that infinitesimal rigidity is a sufficient condition for local asymptotical stability of the equilibrium manifold describing the target formation.
Sample Interview Questions

on women and their families. It has been shown that a positive birth experience includes interpersonal care, information/involvement in decision making, and the physical birthing environment (Rudman, El-Kouri, & Waldenstrom, 2007). Decades of research affirm that birthing experiences are enhanced when women feel respected, valued, and supported. Nurses and nursing care play pivotal roles in the experiences (both positive and negative) that women have during labor and birth, and it is appropriate that the perceptions of nurses be examined thoroughly. Although women’s birth experiences are profoundly influenced by perinatal nurses, the voices of these nurses have not been represented fully in nursing research. Nurses who care for childbearing women have complex roles, including maternal/fetal assessment, proficiency in technical skills, and a high level of interpersonal skills (Hodnett, 1996, 2000; Downe, Simpson, & Traf-
Milieu and function: Toward a multilayer framework for understanding social networks

Social interactions between individuals do not occur in a void. Nor do they take place on a pre-existing fixed social network. Real social behaviour can be understood both to take place on, and to bring about, a complex set of overlapping topologies best described by a multilayer network in which different layers indicate different modes of interaction. Here we distinguish between the milieu within which social organisation is embedded and the transactional relationships that constitute this social organisation. While both can be represented by network structures, their topologies will not necessarily be the same. Researchers in various domains have realised the importance of the context in which individuals are embedded in shaping properties of the functional transactions in which they choose to engage. We review several examples of the relationship between milieu and function and propose a conceptual framework that may help advance our understanding of how social organisation can occur as a result of self-organisation and adaptation.
Modeling and Simulation of a Parallel Mechanical Elbow with 3 DOF

The modeling and simulation of a mechanical elbow of 3 degrees of freedom, is introduced by highlighting the main features of the mechanism related to the design criteria. The mechanical elbow is used as a transhumeral prosthetic part, and it has been built as a parallel topology consisting of electric linear actuators and universal joints. The parallel mechanism has 4 legs: 3 made with electric linear actuators, and the fourth leg provides mechanical support for the whole structure and holds a DC motor that performs the action of gripping objects. Furthermore, this paper shows the inverse kinematics for the elbow by geometric methods, and the MatLab-simulation results show the workspace of the movement and the ability of the mechanical elbow to replicate the movements of a biological one.
ROLE OF COMMUNICATION IN MANAGEMENT TEACHING & RESEARCH IN THE INTERNATIONAL CONTEXT

The understanding of how to convey (when speaking) and interpret (when listening) meaning is always be essential for effective communication, management and relationships. In other instances, management may wish to address employees directly in a uniform fashion without differentiating styles, such as when issuing a personal note from an executive to all employees or when communicating highly important matters with companywide implications. It is important to develop the message and its style around common denominators found in the shared values and culture of the workplace. This paper will describe the Mehrabians’ model of communication as well as critical theory of communication in management teaching and research. Critical theory, which has been a distinguishing feature of the communication research program at one of the Management Schools, in which students are from different – different countries, but significant reflection is required to translate the theory into meaningful classroom experiences.
An Algorithm of Service Selection Based on QoS Preference in Network Computing Environment

In order to select service based on users’ QoS preference, the paper studied and presented several ways to describe QoS preference information. Then, these ways were applied to the algorithm of service selection, the QoS preference function and user’s satisfaction degree which as an evaluation criteria of user were defined. Subsequently,the paper put forward an algorithm of service selection based on QoS preference. Several tests showed that the algorithm could reliably select the optimal service with a good stability.
