What is my essay really saying? Using extractive summarization to motivate reflection and redrafting

This paper reports on progress on the design of OpenEssayist, a web application that aims at supporting students in writing essays. The system uses techniques from Natural Language Processing to automatically extract summaries from free-text essays, such as key words and key sentences, and carries out essay structure recognition. The current design approach described in this paper has led to a more "explore and discover" environment, where several external representations of these summarization elements would be presented to students, allowing them to freely explore the feedback, discover issues that might have been overlooked and reflect on their writing. Proposals for more interactive, reflective activities to structure such exploration are currently being tested.
AjMutator: A Tool for the Mutation Analysis of AspectJ Pointcut Descriptors

Aspect-oriented programming introduces new challenges for software testing. Inparticular the pointcut descriptor (PCD) requires particular attention fromtesters. The PCD describes the set of joinpoints where the advices are woven.In this paper we present a tool, AjMutator, for the mutation analysis of PCDs.AjMutator implements several mutation operators that introduce faults in thePCDs to generate a set of mutants. AjMutator classifies the mutants accordingto the set of joinpoints they match compared to the set of joinpoints matchedby the initial PCD. An interesting result is that this automaticclassification can identify equivalent mutants for a particular class of PCDs.AjMutator can also run a set of test cases on the mutants to give a mutationscore. We have applied AjMutator on two systems to show that this tool issuitable for the mutation analysis of PCDs on large AspectJ systems.
Creating Paths: Living with a very low birth weight infant.

Advances in neonatal nursing and medical interventions have made it possible for the very low birth weight (VLBWj infant to survive. However, it is now time to recognize the intangible costs, emotional stress, marital stress, grief, pain, sorrow, and the disruption of the role transition to parenthood. To facilitate progress in the area of neonatal nursing, systematic efforts were undertaken to examine and describe parental adaptation to the VLBW infant and potential risk for parenting problems after hospital discharge. The purpose of this study was to describe parents' method of adaptation to the problems of caring for a VLBW infant at home. Specifically this study was designed to identify: 1. What strategies parents employed during the adaptation process. 2. What resources parents combined with their strategies of adaptation. 3. What situations promoted or inhibited parental adaptation. The informants consisted of parents of VLBW infants «1500 grams) following hospital discharge. The number of 11 subjects for this study was 14. An exploratory design was used to conduct this study. Each subject was involved in three interview sessions, one month, three months, and five months following hospital discharge of their VLBW infant. Data were sampled theoretically, as guided by the emergent theory. The constant comparative method was used for data analysis. The study wus judged for its degree of trustworthiness using multiple procedures. 12 A basic social process, Creating Paths, was identified as the core category of the theory. creating Paths is the continuous process experienced by parents living with a VLBW infant the first five months after hospital discharge. The process consists of three stages: Gathering, Emerging, and Affirming. Results of this investigation provide a beginning theoretical foundation for assessing the adaptation process of parents with VLBW infants the first five months at home. Neonatal nurses can utilize the model to provide anticipatory guidance and support to benefit parents and their VLBW infant. The model is especially germane to cow~unity health nurses who provide follow-up visits to these parents and their VLBW infants.
Biased random key genetic algorithm with hybrid decoding for multi-objective optimization

A biased random key genetic algorithm (BRKGA) is an efficient method for solving combinatorial optimization problems. It can be applied to solve both single-objective and multi-objective optimization problems. The BRKGA operates on a chromosome encoded as a key vector of real values between [0, 1]. Generally, the chromosome has to be decoded by using a single decoding method in order to obtain a feasible solution. This paper presents a hybrid decoding, which combines the operation of two single decoding methods. This hybrid decoding gives two feasible solutions from the decoding of one chromosome. Experiments are conducted on realistic instances, which concern acquisition scheduling of agile Earth observing satellites.
Registration of Heterogeneous Data Sources in the Case of the Grid Semantic Data Access Middleware ( G-SDAM )

G-SDAM is a semantic data mediation middleware for Grids whi ch allows the integration of multiple data sources using different data structur es and semantics. While traditional data integration requires all data sources to follow common rule s concerning the structure of data (and even more, requires the users to have knowledge about the str ucture of each single data source to be accessed), the G-SDAM approach allows a seamless and transp arent view on distributed data. Local data sources as well as users accessing those data can both be part of Virtual Organizations since G-SDAM is planned to build upon the Globus Toolkit. The enabling element of the middleware is ontology manageme nt including mapping between different data models (e.g. relational models, hierarchical file syst ems, and also ontologies itself) to a global OWL-based ontology database residing on a Global Repositor y N de (GRN). The GRN acts as the gateway to the distributed data sources. Queries can be comp osed in SPARQL using global semantics which can be seen as a common language. Without an agreement o n facts and terms, seamless data integration would not be possible. For each application dom ain there will be different global semantics defined by domain experts. Ontology versioning support and further requirements concerning security, copyright issues, data provenance, etc. are also ddressed by the G-SDAM approach.
FastForward

This paper presents, FastForward (FF), a novel full duplex relay that constructively forwards signals such that wireless network throughput and coverage is significantly enhanced. FF is a Layer 1 in-band full duplex device, it receives and transmits signals directly and simultaneously on the same frequency. It cleanly integrates into existing networks (both WiFi and LTE) as a separate device and does not require changes to the clients. FF's key invention is a constructive filtering algorithm that transforms the signal at the relay such that when it reaches the destination, it constructively combines with the direct signals from the source and provides a significant throughput gain. We prototype FF using off-the-shelf software radios running a stock WiFi PHY and show experimentally that it provides a 3× median throughput increase and nearly a 4× gain at the edge of the coverage area.
Ablation of Peroxiredoxin II Attenuates Experimental Colitis by Increasing FoxO1-Induced Foxp3+ Regulatory T Cells

Peroxiredoxin (Prx) II is an intracellular antioxidant molecule that eliminates hydrogen peroxide, employing a high substrate-binding affinity. PrxII deficiency increases the levels of intracellular reactive oxygen species in many types of cells, which may increase reactive oxygen species–mediated inflammation. In this study, we investigated the susceptibility of PrxII knockout (KO) mice to experimentally induced colitis and the effects of PrxII on the immune system. Wild-type mice displayed pronounced weight loss, high mortality, and colon shortening after dextran sulfate sodium administration, whereas colonic inflammation was significantly attenuated in PrxII KO mice. Although macrophages were hyperactivated in PrxII KO mice, the amount of IFN-γ and IL-17 produced by CD4+ T cells was substantially reduced. Foxp3+ regulatory T (Treg) cells were elevated, and Foxp3 protein expression was increased in the absence of PrxII in vitro and in vivo. Restoration of PrxII into KO cells suppressed the increased Foxp3 expression. Interestingly, endogenous PrxII was inactivated through hyperoxidation during Treg cell development. Furthermore, PrxII deficiency stabilized FoxO1 expression by reducing mouse double minute 2 homolog expression and subsequently activated FoxO1-mediated Foxp3 gene transcription. PrxII overexpression, in contrast, reduced FoxO1 and Foxp3 expression. More interestingly, adoptive transfer of naive CD4+ T cells from PrxII KO mice into immune-deficient mice attenuated T cell–induced colitis, with a reduction in mouse double minute 2 homolog expression and an increase in FoxO1 and Foxp3 expression. These results suggest that inactivation of PrxII is important for the stability of FoxO1 protein, which subsequently mediates Foxp3+ Treg cell development, thereby attenuating colonic inflammation.
Effect of boundary conditions and source truncation in the prediction of flow-generated sound

The influence of the finiteness of the source domain on the application of Curle’s analogy for the computation of flow-generated sound is investigated in the present work. Two aspects are studied: the spurious source of sound induced by CFD boundary conditions in incompressible simulations and the error due to the truncation of the integration source domain. Two validation cases are investigated: a synthetic vortex street and the flow past a confined cylinder, both at low Mach number. The confined flow case presents specific difficulties, related to the presence of boundaries in the near-field of the quadrupolar sources and the existence of dipolar sources.
Self-Reported Trait Mindfulness and Affective Reactivity: A Comprehensive Investigation of Valence, Arousal, and Attention to Emotional Pictures

Mindful attention is qualitatively receptive and non-reactive, and is thought to facilitate adaptive emotional responding. Using a multi-method approach, I studied the relationship between individual differences in self-reported trait mindfulness and electrocortical, electromyographic, electrodermal, and self-reported responses to emotional pictures. Specifically, while subjects passively viewed IAPS pictures, electrocortical data, skin conductance, and also electromyographic data were recorded. Afterwards, subjects rated their subjective valence and arousal while viewing the pictures again. If trait mindfulness reduces general emotional responding, then responses from individuals with high mindfulness would be associated with decreased late positive potential amplitudes, decreased skin conductance response, and decreased subjective ratings of valence and arousal to emotional pictures. High mindfulness would also be associated with a decreased emotional modulation of startle eyeblink amplitudes and of startle P3 amplitudes during emotional pictures. Although analysis showed clear effects of emotion on dependent measures, in general, mindfulness did not moderate these effects.
A framework for ambient applications

Applications are designed traditionally in a top-down manner, starting with explicit user requirements and requiring explicit user interaction to control them. Sensor networks provide a way for the autonomous acquisition of context information, which can be used to control applications without explicit user interaction. In addition, they can be used for context exploration. This enables a semi-automatic generation of new functionality. In this paper we introduce a framework for Ambient Applications (AmbientApps). AmbientApps are applications that can react to the context information with implicit user interaction. Besides providing the context information to AmbientApps, the framework is also characterized by its ability to detect new patterns in sensor data and link them to user actions on devices and pre-empting that user action the next time the same pattern is detected.
Oligoclonal IgG and Free Light Chains in the Cerebrospinal Fluid of Patients with Multiple Sclerosis and Infectious Diseases of the Central Nervous System

Conventional and crossed immunoelectrophoresis were used to characterize oligoclonal γy‐globulin bands of the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS) or subacute sclerosing panencephalitis (SSPE) or other infections of the central nervous system. Most γy‐globulin bands were identified as IgG, but some bands were identified as κ or λ, or both, free light chains, Bands of IgG, showed various degrees of light‐chain diversity, and individual bands appeared in many instances to be derived from more than one clone of cells. Sequential changes of the oligoclonal IgG were observed in SSPE but not in MS. Oligoclonal IgG was detected in sera from most patients with SSPE and some patients with MS.
Searching and navigating petabyte-scale file systems based on facets

As users interact with file systems of ever increasing size, it is becoming more difficult for them to familiarize themselves with the entire contents of the file system. In petabyte-scale systems, users must navigate a pool of billions of shared files in order to find the information they are looking for. One way to help alleviate this problem is to integrate navigation and search into a common framework. One such method is faceted search. This method originated within the information retrieval community, and has proved popular for navigating large repositories, such as those in e-commerce sites and digital libraries. This paper introduces faceted search and outlines several current research directions in adapting faceted search techniques to petabyte-scale file systems.
Active filtering of physiological motion in robotized surgery using predictive control

This work presents a predictive-control approach to active mechanical filtering of complex, periodic motions of organs induced by respiration or heart beating in robotized surgery. Two different predictive-control schemes are proposed for the compensation of respiratory motions or cardiac motions. For respiratory motions, the periodic property of the disturbance has been included into the input-output model of the controlled system so as to have the robotic system learn and anticipate perturbation motions. A new cost function is proposed for the unconstrained generalized predictive controller (GPC), where reference tracking is decoupled from the rejection of predictable periodic motions. Cardiac motions are more complex, since they are the combination of two periodic nonharmonic components. An adaptive disturbance predictor is proposed which outputs future predicted disturbance values. These predicted values are used to anticipate the disturbance by using the predictive feature of a regular GPC. Experimental results are presented on a laboratory testbed and in vivo on pigs. They demonstrate the effectiveness of the two proposed methods to compensate complex physiological motion.

New Directions in Software Safety: Causal Modelling as an Aid to Integration

Analysis of software safety can provide us with much interesting data on potential failure modes of individual software components and of the effects of these failures on the system as a whole. In this paper we describe our approach to software safety analysis, based around integrating notations with diverse causal models, and how we believe it can be used as an aid to the design process. We introduce the Failure Propagation and Transformation Notation (FPTN) as a modelling tool which can be used throughout the software lifecycle as an aid to design and implementation of safe systems. This paper expands upon material presented at the November 1992 IEE Colloquium on Hazard Analysis. [Fenelon92]
Binding lies

Do we feel bound by our own misrepresentations? Does one act of cheating compel the cheater to make subsequent choices that maintain the false image even at a cost? To answer these questions we employed a two-task paradigm such that in the first task the participants could benefit from false reporting of private observations whereas in the second they could benefit from making a prediction in line with their actual, rather than their previously reported observations. Thus, for those participants who inflated their report during the first task, sticking with that report for the second task was likely to lead to a loss, whereas deviating from it would imply that they had lied. Data from three experiments (total N = 116) indicate that, having lied, participants were ready to suffer future loss rather than admit, even if implicitly, that they had lied.
Quantum filtering for systems driven by fermion fields

Recent developments in quantum technology mean that is it now possible to manipulate systems and measure fermion fields (e.g. reservoirs of electrons) at the quantum level. This progress has motivated some recent work on filtering theory for quantum systems driven by fermion fields by Korotkov, Milburn and others. The purpose of this paper is to develop fermion filtering theory using the fermion quantum stochastic calculus. We explain that this approach has close connections to the classical filtering theory that is a fundamental part of the systems and control theory that has developed over the past 50 years.
Lessons from a structural dynamic analysis of retirement behavior in the Netherlands

An energy absorbing type intermediate shaft structure to be incorporated into a steering device of an automobile for transmitting a steering force of a steering wheel to a steering gear, has a shaft inserted in a tube. The shaft has a small cross-sectional area portion and a pressing portion. A cover tube is present around the small cross-sectional area portion. The location at which the pressing portion is formed is regulated so that with the pressing portion bearing against the cover tube, one end edge of the cover tube may lie around the small cross-sectional area portion. A distance alpha between the pressing portion and the cover tube, a distance beta between the cover tube and the tube, and a distance gamma between the shaft and a member associated with a yoke in the steering device are set to satisfy the condition alpha + beta < gamma .
Physiological responses at the critical heart rate during treadmill running

The purposes of this study were to: 1) determine if the critical heart rate (CHR) model for cycle ergometry can be applied to treadmill running; and 2) examine the times to exhaustion (T lim) as well as the ! VO 2 , ratings of perceived exertion (RPE), electromyographic amplitude (EMG AMP) and mean power frequency (MPF) responses during constant heart rate (HR) runs at CHR-5 b·min-1 (CHR-5), CHR, and CHR+5 b·min-1 (CHR+5). Thirteen runners performed an incremental treadmill test to exhaustion. On separate days, 4 constant velocity runs to exhaustion were performed. The total number of heart beats (HB lim) for each velocity was calculated as the product of the average 5 s HR and T lim. The CHR was the slope coefficient of the HB lim versus T lim relationship. The physiological responses were recorded during the constant HR runs. Polynomial regression analyses were used to examine the patterns of responses for all.
The functional‐institutional and consequential‐conflictual sociological approaches to accounting ethics education: Integrations from sustainability and ecological resources management literature

Purpose - There is limited research that utilizes the consequential-conflictual (CC) approaches, which utilized radical orientation of double loop, second order and reorientation of organizational learning strategies. Both the functional-institutional (FI) and CC approaches are integrated with the sustainability and ecological resources management literature. The aim of this paper is to fill this research gap. Design/methodology/approach - The paper applies FI and CC sociological approaches. Findings - This paper's contribution to the managerial auditing education literature is based on the proposition that ethics education can improve the moral and ethical reasoning of auditors, when the educational processes incorporate both the FI and CC sociological organizational learning strategies. The paper suggests that ethics education in auditing could benefit from experiential teaching methods utilized in allied applied disciplines of medicine, engineering, and educational psychology. Research limitations/implications - Sociological approaches have been commonly applied in behavioral managerial accounting and control systems research. This paper extends the FI and CC framework to ethics education in managerial auditing research. Practical implications - The subject of accounting ethics education is important to auditors. When accounting ethics education utilizes both the FI and CC teaching approaches, the managerial auditing education processes become interactive and cooperative by bringing experiential organizational experiences to the classroom. Originality/value - Accounting ethics education is shaped by ecological and environmental sustainability concerns. Recently, business school interest and growth in sustainability management has contributed to the integration of ethics education in managerial auditing and accounting contexts, overcoming the shortcomings accounting programs experienced from stand-alone ethics courses.
Crystal structure of unliganded TRAP: implications for dynamic allostery

Allostery is vital to the function of many proteins. In some cases, rather than a direct steric effect, mutual modulation of ligand binding at spatially separated sites may be achieved through a change in protein dynamics. Thus changes in vibrational modes of the protein, rather than conformational changes, allow different ligand sites to communicate. Evidence for such an effect has been found in TRAP (trp RNA-binding attenuation protein), a regulatory protein found in species of Bacillus. TRAP is part of a feedback system to modulate expression of the trp operon, which carries genes involved in tryptophan synthesis. Negative feedback is thought to depend on binding of tryptophan-bound, but not unbound, TRAP to a specific mRNA leader sequence. We find that, contrary to expectations, at low temperatures TRAP is able to bind RNA in the absence of tryptophan, and that this effect is particularly strong in the case of Bacillus stearothermophilus TRAP. We have solved the crystal structure of this protein with no tryptophan bound, and find that much of the structure shows little deviation from the tryptophan-bound form. These data support the idea that tryptophan may exert its effect on RNA binding by TRAP through dynamic and not structural changes, and that tryptophan binding may be mimicked by low temperature.
