Bridging the Gap between Expert-Novice Differences

Abstract The study adds to the body of knowledge about different types of feedback. Feedback is considered a fundamental component for supporting and regulating learning processes. Especially in computer-based and self-regulated learning environments, the nature of feedback is of critical importance. Hence, this study investigates different types of automatically generated feedback. Seventy-four students participated in the experimental study, in which they had to write texts and create concept maps reflecting their understanding of climate change while receiving three different forms of model-based feedback. Results indicate that concept maps were structurally and semantically more similar to an expert solution than written texts. However, the form of the automatically created model-based feedback did not influence the type of representation.
Semantic Event Mining in Soccer Video Based on Multiple Feature Fusion

In this paper, we present a football event detection method by using multiple feature extraction and fusion. Instead of using low-level features, the proposed method is built upon visual, auditory features, text and audio keywords. Promising event detection results have been achieved. By using the proposed method, we have been able to detect the football events accurately. Experimental results have shown our proposed method is effective for football event detection.
10 Computational Cell Biology - The Stochastic Approach

In broad terms, the current interest in " computational cell biology " reflects the contemporary fascination with electronic networks of all kinds. There is a widespread feeling that the speed of computers and the sophistication of programmers can at last match the bewildering molecular complexity of living cells. This viewpoint is encouraged and fed by recent genomic studies, which have built up such an impetus that they are now pushing into areas outside the genome. Evidently, sequence information by itself cannot explain the functioning of a living cell or organism. It is also true that we have built up, over the past century, an enormous body of information about proteins and other molecules inside cells. Why should we not — the argument goes — store, collate and analyze these data by comprehensive, computer-intensive techniques similar to those currently employed to analyze genomes? Unfortunately, no consensus presently exists as to how best to perform this analysis, or to what we can expect as a result. One clear-cut function of computers in cell biology is to store large amounts of information in a logical and accessible form. This role has seen its most public triumph in the generation of genomic databases, but also underpins the giant strides made in the determination of protein structure. Many databases containing integrated information on specific organisms have been developed and some of these allow the user to access specific molecular details on individual cells, such as WormBase 1 and EcoCyc 2. There are also large programs containing information about specific cell types, such as the software developed by Denis Noble to analyze the behavior of heart muscle cells 3. Several ambitious projects have been initiated that aim to simulate entire cells or parts of cells at a molecular level, such as E-CELL 4 and the Virtual Cell 5. Computers were of course used by biologists before the genomic era. The area of metabolic modeling, for example, with its roots in enzyme kinetics, was one of the earliest to be adapted to computer simulation. Many software packages have been written that allow the kinetic performance of enzyme pathways to be represented and evaluated quantitatively, such as GEPASI 6 , MIST 7 and 2 Chapter 10 SCAMP 8. This is also an area of commercial interest and biotechnology companies engaged in the production of food or drugs by fermentation or allied processes routinely evaluate their production by flux-analysis …
Designing 3D Mesenchymal Stem Cell Sheets Merging Magnetic and Fluorescent Features: When Cell Sheet Technology Meets Image-Guided Cell Therapy

Cell sheet technology opens new perspectives in tissue regeneration therapy by providing readily implantable, scaffold-free 3D tissue constructs. Many studies have focused on the therapeutic effects of cell sheet implantation while relatively little attention has concerned the fate of the implanted cells in vivo. The aim of the present study was to track longitudinally the cells implanted in the cell sheets in vivo in target tissues. To this end we (i) endowed bone marrow-derived mesenchymal stem cells (BMMSCs) with imaging properties by double labeling with fluorescent and magnetic tracers, (ii) applied BMMSC cell sheets to a digestive fistula model in mice, (iii) tracked the BMMSC fate in vivo by MRI and probe-based confocal laser endomicroscopy (pCLE), and (iv) quantified healing of the fistula. We show that image-guided longitudinal follow-up can document both the fate of the cell sheet-derived BMMSCs and their healing capacity. Moreover, our theranostic approach informs on the mechanism of action, either directly by integration of cell sheet-derived BMMSCs into the host tissue or indirectly through the release of signaling molecules in the host tissue. Multimodal imaging and clinical evaluation converged to attest that cell sheet grafting resulted in minimal clinical inflammation, improved fistula healing, reduced tissue fibrosis and enhanced microvasculature density. At the molecular level, cell sheet transplantation induced an increase in the expression of anti-inflammatory cytokines (TGF-ß2 and IL-10) and host intestinal growth factors involved in tissue repair (EGF and VEGF). Multimodal imaging is useful for tracking cell sheets and for noninvasive follow-up of their regenerative properties.

The general form of supersymmetric solutions of N = (1, 0) U(1) and SU(2) gauged supergravities in six dimensions

We obtain necessary and sufficient conditions for a supersymmetric field configuration in the N = (1, 0) U(1) or SU(2) gauged supergravities in six dimensions, and impose the field equations on this general ansatz. It is found that any supersymmetric solution is associated with an structure. The structure is characterized by a null Killing vector which induces a natural 2 + 4 split of the six-dimensional spacetime. A suitable combination of the field equations implies that the scalar curvature of the four-dimensional Riemannian part, referred to as the base, obeys a second-order differential equation; surprisingly, for a large class of solutions the equation in the SU(2) theory requires the vanishing of the Weyl anomaly of N = 4 SYM on the base. Bosonic fluxes introduce torsion terms that deform the structure away from a covariantly constant one. The most general structure can be classified into terms of its intrinsic torsion. For a large class of solutions the gauge field strengths admit a simple geometrical interpretation: in the U(1) theory the base is Kahler, and the gauge field strength is the Ricci form; in the SU(2) theory, the gauge field strengths are identified with the curvatures of the left-hand spin bundle of the base. We employ our general ansatz to construct new solutions; we show that the U(1) theory admits a symmetric Cahen–Wallach4 × S2 solution together with a compactifying pp-wave. The SU(2) theory admits a black string, whose near horizon limit is AdS3 × S3, which is supported by a self-dual 3-form flux and a meron on the S3. In the limit of the zero 3-form flux we obtain the Yang–Mills analogue of the Salam–Sezgin solution of the U(1) theory, namely R1,2 × S3. Finally we obtain the additional constraints implied by enhanced supersymmetry, and discuss Penrose limits in the theories.
Security-Enhanced Darwin: Porting SELinux to Mac OS X

Security-Enhanced Darwin (SEDarwin) is a port of access control elements derived from the National Security Agency’s Security Enhanced Linux (SELinux) to Darwin, the Open Source core of Apple’s Mac OS X operating system. Mac OS X combines both Open Source and proprietary technologies into a widely-used, production-quality UNIX-based workstation. Because Darwin is available under an Open Source license, it is possible to add mandatory access controls while still maintaining compatibility with the large base of user space applications, proprietary graphical components, and programming frameworks. While it was straightforward to port many of the SELinux components, Darwin’s unique architecture meant significant new engineering was necessary in order to provide SELinux-style access controls consistently across the entire system. This paper describes the component technologies in Darwin, the areas of significant new development, and provides comparisons to SELinux.
Capturing Developmental Patterns in Intonation Acquisition : A Target-oriented Parametric Approach

Prosody links and organize semantic information, syntactic and morphological structure as well as segmental sequences into a consistent set of address frames like syllables, metrical feet, phonological word and intonational phrases (Levelt, 1989). With this prosodic frame infants learn to recognise the single segments of the speech stream during the acquisition process. The interaction between prosody and statistics in the segmentation of fluent speech suggests that prosody acts as a filter to find out possible word–like sequences in the speech stream (Shukla et al., 2007). The ability to segment fluent speech into words emerges during the first year of life, whereas the perception of phonetic representation of intonation is well developed with birth (Echols and Marti, 2004; Vihman et al., 2004). Therefore the prosodic development has been claimed to be the starting point for the production of speech as even in infants’ cries different cry melodies and fundamental frequencies in the earliest communicative gestures have been noted (Gilbert and Robb, 1996; Wermke et al., 2002). Even pre-linguistic babbling depends on the input and has been claimed to show adult–like prosody (Siegel et al., 1990; Halle et al., 1991; Davis et al., 2000). But the production of intonation depends on the articulatory abilities of the child and remains difficult for infants and toddlers to produce in a stable manner (Snow and Balog, 2002; Oller et al., 2007). In the field of prosody acquisition two different approaches are common to describe the development of intonation (Stoel-Gammon and Dunn, 1985): the independent and the relational approach. In an independent analysis of intonation (Cruttenden, 1997; Crystal, 1986) the child’s productions are not compared to mature models. Intonation contours are described with reference to properties such as direction (i.e., falling or rising), accent range (i.e., amplitude of pitch change), and complexity (e.g., changes in direction measured in semitones). Based on these
Constructing public and political discourse on alcohol issues: towards a framework for analysis.

AIMS To examine the possibilities for research into news reporting and its role in reflecting and informing public and political beliefs and action in relation to alcohol and drinking practices. METHOD Studies on media and alcohol, focusing on the role of media in relation to alcohol consumption and drinking-related practices, policies and beliefs. RESULTS Most research on alcohol and media has focused on either advertising or entertainment media content, rather than on news reporting and its wider social implications. CONCLUSION The role of news reporting could usefully be widened. We offer a framework for analysing the role of news media in relation to public debate and practice with regard to alcohol and drinking.
Model-based compliant motion control scheme for assembly tasks using vision and force information

This paper proposes model-based compliant motion control scheme for assembly tasks using vision and force information. Many problems, especially assembly tasks, could be solved by integrating visual servoing and impedance control with model-based compliant motion design, in which the coordinate frame of the impedance control is attached to the model of assembled object. To implement the model-based compliant motion control scheme, real-time model-based object pose estimation is used for the visual servoing implemented by a position-based approach. The coordinate frame used for the impedance control, which is attached to the object model, is determined based on the estimated object pose. The proposed control is effective for assembly of two parts like connector insertion task, in which the compliant motion should be designed according to the geometric structure of the assembled part, such as a shape of a socket. Finally, experimental results illustrate the effectiveness of the proposed control.
Drosophila Brakeless Interacts with Atrophin and Is Required for Tailless-Mediated Transcriptional Repression in Early Embryos

Complex gene expression patterns in animal development are generated by the interplay of transcriptional activators and repressors at cis-regulatory DNA modules (CRMs). How repressors work is not well understood, but often involves interactions with co-repressors. We isolated mutations in the brakeless gene in a screen for maternal factors affecting segmentation of the Drosophila embryo. Brakeless, also known as Scribbler, or Master of thickveins, is a nuclear protein of unknown function. In brakeless embryos, we noted an expanded expression pattern of the Krüppel (Kr) and knirps (kni) genes. We found that Tailless-mediated repression of kni expression is impaired in brakeless mutants. Tailless and Brakeless bind each other in vitro and interact genetically. Brakeless is recruited to the Kr and kni CRMs, and represses transcription when tethered to DNA. This suggests that Brakeless is a novel co-repressor. Orphan nuclear receptors of the Tailless type also interact with Atrophin co-repressors. We show that both Drosophila and human Brakeless and Atrophin interact in vitro, and propose that they act together as a co-repressor complex in many developmental contexts. We discuss the possibility that human Brakeless homologs may influence the toxicity of polyglutamine-expanded Atrophin-1, which causes the human neurodegenerative disease dentatorubral-pallidoluysian atrophy (DRPLA).
Ubicast: An Enhanced Application-Level Multicast Protocol

This paper presents Ubicast, an enhanced application- level multicast protocol. Ubicast is built upon Pastry, a scalable and self-organizing peer-to-peer substrate overlay, and leverages its merits of reliable application-level routing and object location. Ubicast is mainly applied to such real-time multimedia applications with QoS heterogeneousness as multimedia streaming service, video-on-demand. The paper makes two contributions to the study of application-level multicast: (1) Ubicast extends traditional degree-bound model and satisfies nodes’ heterogeneous QoS requirements to provide customizable multicast services. It tries to minimize the delay radius of the multicast tree, while meeting different bandwidth requirements. (2) Priority Joining Algorithm is proposed to limit the number of nodes that a participant needs to probe. The join cost is decreased substantially to guarantee the scalability for a potentially large network topology. Simulation and experimental analysis confirm the performance improvement of Ubicast which is especially suited for small sized multicast groups.

Information Processing and Management Sampling Strategies for Information Extraction over the Deep Web

Information extraction systems discover structured information in natural language text. Having information in structured form enables much richer querying and data mining than possible over the natural language text. However, information extraction is a com-putationally expensive task, and hence improving the efficiency of the extraction process over large text collections is of critical interest. In this paper, we focus on an especially valuable family of text collections, namely, the so-called deep-web text collections, whose contents are not crawlable and are only available via querying. Important steps for efficient information extraction over deep-web text collections (e.g., selecting the collections on which to focus the extraction effort, based on their contents; or learning which documents within these collections—and in which order—to process, based on their words and phrases) require having a representative document sample from each collection. These document samples have to be collected by querying the deep-web text collections, an expensive process that renders impractical the existing sampling approaches developed for other data scenarios. In this paper, we systematically study the space of query-based document sampling techniques for information extraction over the deep web. Specifically, we consider (i) alternative query execution schedules, which vary on how they account for the query effectiveness, and (ii) alternative document retrieval and processing schedules, which vary on how they distribute the extraction effort over documents. We report the results of the first large-scale experimental evaluation of sampling techniques for information extraction over the deep web. Our results show the merits and limitations of the alternative query execution and document retrieval and processing strategies, and provide a roadmap for addressing this critically important building block for efficient, scalable information extraction.
Advanced Statistical and Graphical features of SAS ® PHREG

ABSTRACT Survival analysis involves the modeling of time-to-event data whereby death or failure is considered an "event". The graphic presentation of Cox proportional hazards model using SAS PHREG is a significant tool which facilitates effective data exploration in survival analysis. The SAS PROC PHREG can generate some of the useful survival analysis plots using the ODS graphics option in version 9.1. 3. In this paper, we will demonstrate the advanced features of PHREG for investigating the cumulative martingale residual plots and for selecting best candidate models in model selection. In clinical trials, potential outlier individuals who ‘died far too early’ or ‘lived far too long’ are identified and compared to what the fitted model predicts. The cumulative residuals from PROC PHREG are used to investigate the model specification error of covariate and validate the proportion hazard function. Methods to identify outliers are commonly based on Cox regression residuals such as martingale and deviance residuals. We will use PROC GPLOT in SAS/GRAPH to generate these two residual plots and to detect influential outliers. We will outline a method to perform all possible subset model selection within user-defined subsets using AIC information criterion. Also we will discus the new and improved features of the BPHREG, an experimental upgrade to PHREG procedure that has some user-friendly options such as ‘class’, the ‘hazards ratio’, and ‘strata’ statements which can be used to fit Cox proportional hazards model more efficiently.
Does the Early Exercise Premium Contain Information About Future Underlying Returns?

We investigate the information content of the call (put) Early Exercise Premium, or EEP, defined as the normalized difference in prices between otherwise comparable American and European call (put) options. The call EEP specifically captures investors' expectations about future lump sum dividend payments as well as other state variables such as conditional volatility and interest rates. From that perspective, the EEP should also be related to future returns of the underlying security. Little is known about the EEP, largely because it is usually unobservable for most underlying securities. The FTSE 100 index is an exception in that regard, because it has both American and European options contracts that are traded in large volumes. We use data of the FTSE 100 index, and its American and European options contracts, from which we compute a time series of the EEP. Interestingly, we find that the EEP is a good forecaster of returns at daily horizons. This forecastability is not due to time-variation in market risk premia or liquidity. Importantly, we find that the predictability stems primarily from the ability of the EEP to forecast innovations in dividend growth, rather than other components of unexpected returns. Overall, we use several empirical and simulations methods to establish predictability of the underlying with an options market variable, link this predictability to information about cash flow fundamentals, and thereby provide clear support for Black's (1975) conjecture that informed investors prefer to trade on their superior information about fundamentals in the options market relative to the underlying.
