Keyphrase Rubric Relationship Classification in Complex Assignments

— Complex assignments are open-ended question with varying content irrespective of diversity of course and mode of communication. With sheer scale comes issue of reviews that are incomplete and lack details leading to high regrading requests. As such to automatically relate the contents of assignments to scoring rubric, in this work we present a very ﬁrst work on keyphrase-rubric relationship classiﬁcation i.e. we will try to relate the contents to rubrics by solving it as classiﬁcation problem. In this study, we analyze both supervised and unsupervised methods to ﬁnd that supervised approaches outperform unsupervised approaches and topic modelling approaches, despite data limitation with supervised approaches producing maximum results of 0 . 48 F 1 -Score and unsupervised approach producing best result of 0 . 31 F 1 -Score. We further present exhaustive experimentation and cluster analysis using multiple metrics identifying cases where the unsupervised and supervised methods are usable.
An Approach for Selecting Cloud Service Adequate to Big Data Case Study: E-health Context

The expanding Cloud computing's services offers great opportunities for consumers to find the best service and best cost. It offers a computing power and a storage space adapted especially for Big Data processing. However, it raises new challenges on how to select the best service out of the huge pool. It is time-consuming for consumers to collect the necessary information and analyze all service providers to make the right decision. Moreover, it'is a highly demanding task from a computational perspective, because the same computations may be conducted repeatedly by multiple consumers who have similar requirements. Therefore, in this paper, we propose an approach based on Analytic Hierarchy Process (AHP) method, which manages the selection of the Cloud Service adequate to Big Data based on its parameters and criteria. We applied this approach on a case study in order to validate its efficity. The studied case is about the selection of the adequate Cloud Service for Big Data in the context of National Health Service (NHS) of United Kingdom (UK).
Uniform energy distribution in a pattern-forming system of surface charges

We consider a variational model for a charge density $u\in\{-1,1\}$ on a (hyper)plane, with a short-range attraction coming from the interfacial energy and a long-range repulsion coming from the electrostatic energy. This competition leads to pattern formation. We prove that the interfacial energy density is (asymptotically) equidistributed at scales large compared to the scale of the pattern. We follow the strategy laid out in [G. Alberti, R. Choksi, F. Otto, Uniform energy distribution for an isoperimetric problem with long-range interactions, J. A.M.S. ]. The challenge comes from the reduced screening capabilities of surface charges compared to the volume charges considered in that paper.
Gravastar under the framework of Braneworld Gravity

Gravastars have been considered as a serious alternative to black holes in the past couple of decades. Stable models of gravastar have been constructed in many of the alternate gravity models besides standard General Relativity (GR). The Randall-Sundrum (RS) braneworld model has been a popular alternative to GR, specially in the cosmological and astrophysical context. Here we consider a gravastar model in RS brane gravity. The mathematical solutions in different regions have been obtained along with calculation of matching conditions. Various important physical parameters for the shell have been calculated and plotted to see their variation with radial distance. We also calculate and plot the surface redshift to check the stability of the gravastar within the purview of RS brane gravity.
Distance Aware Location Based Optimization for AODV in Mobile Ad HOC Networks

An Ad hoc network is a decentralized and mobile in nature due to which network topology changes dynamically. Therefore, MANET faces new challenges of routings. This research work is based on one of reactive routing protocol called Ad hoc On-demand Distance Vector (AODV). AODV uses flooding technique for route discovery process which results in generation of huge number of route request (RREQ) packets. This flaw of AODV has been already controlled by a technique called GeoAODV. This research work proposed an enhancement of GeoAODV called DG-AODV (Distance based GeoAODV), which further decreases the number of route request messages within the area defined by flooding angle. This paper also focuses on the comparative study of DG-AODV with AODV and GeoAODV. This comparative study shows that DG-AODV’s packet delivery ratio increases, and route discovery time decreases in comparison with other two routing protocols.
Distributed Optimization Using ALADIN for MPC in Smart Grids

This article presents a distributed optimization algorithm tailored to solve optimization problems arising in smart grids. In detail, we propose a variant of the augmented Lagrangian-based alternating direction inexact Newton (ALADIN) method, which comes along with global convergence guarantees for the considered class of linear-quadratic optimization problems. We establish local quadratic convergence of the proposed scheme and elaborate its advantages compared with the alternating direction method of multipliers (ADMM). In particular, we show that, at the cost of more communication, ALADIN requires fewer iterations to achieve the desired accuracy. Furthermore, it is numerically demonstrated that the number of iterations is independent of the number of subsystems. The effectiveness of the proposed scheme is illustrated by running both an ALADIN and an ADMM-based model predictive controller on a benchmark case study.

Introducing anecdote circles as an alternative method to focus groups in the pedagogic impact evaluation of a new digital Nurse Navigator system

The construction and labeling of a relatively disparate set of university information technology systems as the “Nurse Navigator System” were routed in the principles of broader design research where methodologies of teaching, learning, and assessment were used to drive educational innovation within and between clinical and academic teaching. In terms of pragmatic design and appearance, this was straightforward; however, the theoretical basis of the design was more complex and rooted in core pedagogic design principles. Responding to the outcome of the initial evaluation of the system was therefore critical in the iterative developmental design of the Nurse Navigator System. Evaluation necessitated the collation of data which could tangibly and qualitatively examine whether expectations of such a conglomerate set of information technology criteria were realistic in practice. This pilot period of adjustment was recognized as a time to allow for configuring, fine-tuning, and assessment of purposefulness to the student cohort using it and in keeping with the need to co-construct learning and resource needs of students in practice. Evaluating the effectiveness of the preliminary pedagogic design of the Nurse Navigator System necessitated reliable indicators of engagement and learning. This research methods case study provides an overview of the qualitative evaluation of the impact of the new Nurse Navigator System using anecdote circles as an alternative to Focus Groups.
Predicting Online Customer Shopping Behavior

INTRODUCTION Business-to-consumer (B2C) is the most common online business type, which attempts to reach individual consumers. Compared to the brickand-mortar environment, the use of the Internet for business-toconsumer transactions presents obvious advantages. The openness of the Internet creates opportunities for virtually all companies ranging from small start-ups to Fortune 100 companies. In particular, it allows companies to offer direct sales to their customers through an electronic channel (Hoffman, et al, 1996). In the bricks-and-mortar stores, sales people are hired to distinguish shoppers and to stimulate their maximum consuming desire based on their in-store behavior. When shoppers show special interest in some specific product, sales people will help them find what they are looking for. In other cases, for shoppers who are merely window shopping, sales person can recommend some product to entice their shopping appetence. However, in the virtual shopping environment, there is no sales person to perform this role. Therefore, to understand consumer behavior in virtual stores is very important for online business. This research aims to provide theoretical analysis to explain consumers’ shopping behavior in virtual stores. We first review literatures on aspects of customers’ online purchasing behavior, and then propose a model for customer online behavior.
MZET: Memory Augmented Zero-Shot Fine-grained Named Entity Typing

Named entity typing (NET) is a classification task of assigning an entity mention in the context with given semantic types. However, with the growing size and granularity of the entity types, few previous researches concern with newly emerged entity types. In this paper, we propose MZET, a novel memory augmented FNET (Fine-grained NET) model, to tackle the unseen types in a zero-shot manner. MZET incorporates character-level, word-level, and contextural-level information to learn the entity mention representation. Besides, MZET considers the semantic meaning and the hierarchical structure into the entity type representation. Finally, through the memory component which models the relationship between the entity mention and the entity type, MZET transfers the knowledge from seen entity types to the zero-shot ones. Extensive experiments on three public datasets show the superior performance obtained by MZET, which surpasses the state-of-the-art FNET neural network models with up to 8% gain in Micro-F1 and Macro-F1 score.
From Ontologies to the Semantic Web: The Engineering of Knowledge

In any context area, knowledge management requires a holistic view of knowledge from the single, individual user to a global community of practice. This paper suggests a methodology that supports the engineering of knowledge with this vision in mind. The approach uses ontologies to structure the information so that it is comprehensible to a single, individual user at the user’s level of understanding or “view”. Various types of ontologies are incorporated into a Semantic Web environment allowing larger communities of practice to use them as a unified whole. The methodology is demonstrated using a complex problem space — ballistic missile defense.
Let’s Talk about Success: A Proposed Foresight Outcomes Framework for Organizational Futurists

A Foresight Outcomes Framework is proposed as mechanism for organizational futurists to stimulate and frame dialogue about successful outcomes for the integration of foresight. It builds the framework upon a key assumption that the goal of the organizational futurist is to influence the decision-making process. It explores different levels of outcomes and identifies examples of evaluating outcomes and how they relate to decision-making. Social constructionism is recommended as a guiding perspective informing the use of the framework. With these pieces in place, the framework itself is described and explained, following by implications, conclusions, and recommendations for further
Critical Appraisal of a Qualitative Research: “Relatives’ Involvement in Nursing Care: A Qualitative Study Describing Critical Care Nurses’ Experiences”

The critique of research studies is an essential process that helps us in the synthesis of knowledge to use it in conducting new research or to use in practice. In the current paper, author critiques a qualitative research entitled “Relatives’ involvement in nursing care: A qualitative study describing critical care nurses” (Engstrom, Uusitalo, & Engstrom, 2011) for educational purposes. There are many benefits of research critique includes but not limited to broaden understanding of studies carried by scholars, summarize knowledge for using in practice, provide a knowledge base to conduct a new study and to determine the strengths and limitations of a qualitative research study. The following critique will be guided through criteria which are presented at the end of the article. [Saleh AM.

The God of Abraham, A Mathematician's View: Is there a Mathematical Argument for the Existence of God?

Research into the origin and nature of the Hebrew alphabet, and the mathematical structure underlying the sequence of letters of the Hebrew text of Genesis has led to an extraordinary and unexpected discovery of a geometric metaphor in the letter-sequence of the Hebrew text of Genesis that underlies and is held in common by the spiritual traditions of the ancient world. This metaphor models embryonic growth and self-organization. It applies to all whole systems, including those as seemingly diverse as meditation practices and the mathematics fundamental to physics and cosmology. Findings demonstrate that the relationship between physical theory and consciousness, expressed in explicit geometric metaphor, was understood and developed several thousand years ago.
Relationship between Elastic Recovery and Linear Amplitude Sweep as Asphalt Binder Fatigue Tests

Elastic recovery is a new performance test that shows the fatigue behavior of pure and modified binders. Results of Researches show a strong correlation between elastic recovery test and other fatigue tests on asphalt binders and mixes. This test requires great precision in sample preparation, timing and temperature control during the test. Many researches have been done to simulate and predict the fatigue performance of binders. In this paper, the relationship between the Linear Amplitude Sweep (LAS) and elastic recovery test results was studied. For this purpose, four types of pure and ethyl vinyl acetate (EVA) modified binders were used as laboratory specimens. The LAS test outputs were analyzed using the viscoelastic continuum damage method and compared with the results of elastic recovery test. The results showed the LAS test could be employed as a more accurate and less time consuming test in order to predict the fatigue performance of the asphalt binders.
South African national HIV prevalence, incidence, behaviour and communication survey, 2008: a turning tide among teenagers?

This report is the third in a series of population-based HIV seroprevalence surveys that started in 2002 and were repeated in 2005 and again in 2008. The survey found that South Africas HIV epidemic has leveled off at a prevalence of 10.9 percent for people aged two years and older with 5.2 million people estimated to be living with HIV in 2008. HIV prevalence has also declined among children aged 2-14 from 5.6 percent in 2002 to 2.5 percent in 2008 and a decline in new infections has also been noted among teenagers aged 15-19. But the survey warns that the overall situation remains "dire" since South Africa has the worlds largest HIV-positive population.
Towards A UML Profile For Building On Top of An Existing Application

Copy right Idea Grou p Inc. Copy right Idea Grou p Inc. INTRODUCTION Applications are more and more often built on top of existing ones. Legacy applications and Enterprise Ressource Planning (ERP) are typical examples of development on top of a existing applications or components. It is very important to deal with the particularities of such context in the earliest stages of the process, and especially during the analysis phase, in order to control the risks inherent to this kind of development. Therefore, it is useful to clearly define as soon as possible what will be kept from the running application, why and how. Integration and interfacing aspects have also to be studied carefully. Problems related to building on top of existing applications have been studied from the implementation point of view [Fo99,Be97,Op92]. But we believe that it has to be taken into consideration already during the analysis phase. Indeed, in addition to the code itself, the expertise about the functional domain and the interfaces (describing the relationships the existent application may have with others systems) may also be of interest, as it will be shown in this paper. UML [OMG,RJB98,BRJ98] is an object-oriented graphical language. It is now a standard notation used by programmers as well as domain expert, through the whole development cycle. UML is customizable through the notion of profile [JBR98] which allows to re-assemble a set of extensions dedicated to a particular kind of application or development process. It has already been used in various domains [NF00,KS00]. In this paper, we present a profile dedicated to development on top of running applications. The profile presented in this paper is part of the COOP methodology (Contextual Object-Oriented Process) where we propose a flexible approach for analysis and design with regards to the context of the application. The need for situation-specific approaches, to better satisfy particular situation requirements, has already been emphasized [SH96, RR01]. In COOP, the application context is described through different criterias; to develop the application on top of existing ones is one of these criterias. Flexibility is handled through the different fragments proposed in each phase of the process. Some of them are useful whatever is the context of the application, others are dedicated to the criteria. The profile presented in this paper is used through the fragments dedicated to applications developped on top of running ones. By situating the application in its context and by choosing the interesting fragments, the process is tailored for the application under consideration in order to allow a more efficient development process. The paper is organized as follows. In section 2 we introduce a dedicated profile. Section 3 highlights the different aspects of preservation. Section 4 shows how this profile is used through the COOP methodology. Section 5 presents our conclusions.

Influencia de un programa de actividad física sobre la atención selectiva y la eficacia atencional en escolares (Influence of a physical activity program on selective attention and attentional efficiency in school children)

La atencion se ha revelado como un mecanismo de control que desempena un rol fundamental en la organizacion jerarquica de procesos no solo neurocognitivos sino tambien motivacionales y emocionales. La reciente evidencia cientifica que apoya la existencia de una relacion directa entre ejercicio fisico y atencion demanda la necesidad de definir las premisas para el diseno de intervenciones con el objetivo de examinar que tipo de actividad fisica puede influir de manera mas efectiva en la evolucion cognitiva preadolescente subyacente al ejercicio fisico. El objetivo fue analizar el efecto sobre la atencion de un programa de actividad fisica de alta intensidad. Se diseno un estudio cuasi-experimental intrasujetos en el que participaron 24 ninos y 20 ninas de 9-10 anos pertenecientes a Espana. Se evaluo la atencion mediante el Test de Caras. Se aplico estadistica no parametrica para el analisis de datos (prueba de Wilcoxon). Se apreciaron efectos sobre las variables de aciertos, errores, omisiones, control inhibitorio y eficacia atencional (p entre .05 y .05). Los resultados sugieren que la realizacion de un programa de actividad fisica de alta intensidad, con 16 sesiones de 40-50 minutos de duracion/sesion, basado en ejercicios de fuerza-resistencia muscular y desafios cooperativos podria tener efectos positivos sobre la atencion tanto en ninos como en ninas de 9-10 anos de edad. Abstract. Attention has been revealed as a control mechanism that plays a fundamental role in the hierarchical organization of processes that are not only neurocognitive but also motivational and emotional. Recent scientific evidence supporting the existence of a direct relationship between physical exercise and attention demands the need to define the premises for the design of interventions with the aim of examining which type of physical activity can more effectively influence preadolescent cognitive evolution underlying physical exercise. The objective was to analyze the effect of a high intensity physical activity program on attention. A quasi-experimental intra-subject study was designed. 24 boys and 20 girls aged 9-10 years old from Spain participated in the study. Attention was evaluated through the “Face Test”. Non-parametric statistics were applied for the data analysis (Wilcoxon test). Effects were observed on the variables of successes, errors, omissions, inhibitory control, and attentional efficacy (p between .05). The results suggest that the realization of a program of physical activity of high intensity, with 16 sessions of 40-50 minutes per session, based on muscular strength-endurance exercises and cooperative challenges, could have positive effects on attention in both boys as girls of 9-10 years of age.
Assessment of Health - Seeking Behaviour among Snakebite Victims in a Rural Community of Kaltungo Local Government Area, Gombe State, Nigeria

Background of the study: Snakebite is one of the devastating NTDs, the outcome of its management depends on the health-seeking behavior of the victims. There are many factors that influence healthcare seeking behavior in general, which of these factors that influence the healthseeking behavior of snakebite victims in communities of Kaltungo local government area is not clearly known. Aim: The aim of this study is to assess predisposing factors to snakebite, and the health-seeking behavior of the snakebite victims in kaltungo LGA, Gombe. Methodology: A descriptive cross-sectional study was conducted among 398 participants in a community of Kaltungo local government area. Pre-tested and standardized questionnaires were used to obtain relevant information by trained research assistants. Result: Visits to traditional healers (48%) was most common source of healthcare sought after snakebite. This was followed by visits to hospital (41.7%), spiritual healers (4.8%) and Chemist (5.5%). About a third (33.2%) of the respondents considered treatment effectiveness as the most important factor affecting health-seeking behaviour. This was followed by affordability (20.9%), proximity (11.8%), relative cost of treatment (10.8%) and service availability (6.0%). Educational level (X = 7.584, p=0.05) is significantly associated with seeking healthcare from formal source Conclusion: Appropriate health-seeking behaviour among snakebite victims was found to be high among the educated. Thus, those with lower levels of education need to be targeted during health education program to improve health-seeking behaviour among snakebite victims. In addition, health insurance schemes should be extended to cover more of the population.
