Development of a contextualised MALL research framework based on L2 Chinese empirical study

ABSTRACT Contextualised mobile assisted language learning (MALL) has been known for its potential in language learning rooted in social constructivism theories. However, a consistent approach to constituents of contextualised MALL, in addition to a quantitative tool to evaluate it, is missing in reported case studies. The present research, drawing upon literature context definitions, presents a research framework for analysing, designing and evaluating contextualised MALL. Real world and real life context variables were analysed and the potential influence of the country (target and non-target) and the mobile activities language learning orientation (generic/dedicated) on contextualised MALL was suggested. Empirical data collected from 53 L2 Chinese students in Taiwan and Israel, encompassing 296 types of MALL activities performed by students, was used to develop the contextualised MALL model as well as an index for measuring real world and real life context learning. This measuring index was subsequently established in a combined top-down and bottom-up process, using pre-defined context literature augmented with students’ stories. At the end of the research procedure a quantitatively operative evaluation tool was developed. Real world was measured by the amount of content activity in relation to the place, typical or non-typical objects of the place and typical situations at the place. Real life was measured by the degree to which other tools assisted in other core activities whose purpose was not learning. The paper presents the research framework, the developed model and index with examples illustrating their application. They are offered for the research and practice community to use.
Depth-guided Disocclusion Inpainting for Novel View Synthesis *

The generation of novel views is a crucial processing step in 3D content generation, since it gives control over the amount of depth impression on (auto-)stereoscopic devices and enables free-viewpoint video viewing. A critical problem in novel view generation is the occurrence of disocclusions caused by a change in the viewing direction. Thus, areas in the novel views may become visible that were either covered by foreground objects or were located outside the borders in the original views. In this paper, we propose a depth-guided inpainting approach which relies on efficient patch matching to complete disocclusions along foreground objects and close to the image borders. Our method adapts its patch sizes depending on the disocclusion sizes and incorporates the depth information by focusing on the background scene content for patch selection. A subjective evaluation based on a user study demonstrates the effectiveness of the proposed approach in terms of quality of the 3D viewing experience.
Persistent Nerves Revisited

A nerve is a simplicial complex derived from a cover of a topological space. Nerves appear all over computational topology and geometry, e.g. a Delauney triangulation is the nerve of a Voronoi diagram and the Čech complex is the nerve of a collection of metric balls. They are used to solve problems concerning surface reconstruction, homology inference, and homological sensor networks, among other areas. If one has an open cover of a paracompact space in which all non-empty intersections of the cover elements are contractible, i.e. it is a good cover, then its nerve is homotopy equivalent to the covered space. This result is known as the Nerve Theorem. It has a natural extension to the setting of persistent homology called the Persistent Nerve Lemma (PNL), due to Chazal and Oudot [2]. The PNL implies that given a filtration of covers of a filtration of spaces such that at each time the cover is good, then the persistent homology of the space filtration is that of the nerve filtration. Good covers are not always an option, e.g. if a metric space is not convex then the metric balls of a finite point sample may cover the space, but they won’t be a good cover without adding other conditions. The requirement of having a good cover in order to invoke the PNL is the motivation for our work – instead we assume the cover elements’ homology is trivial when included into a later scale. Recently, Botnan and Spreemann assumed an interleaving between two cover filtrations to prove a bound on the bottleneck distance between the persistence diagrams of their nerve filtrations [1]. Govc and Skraba [3] considered a simplicial filtration and a cover of the terminal complex, using it to construct a cover filtration by taking the intersection of the cover with the simplicial filtration at each scale. They assumed that the persistence modules of all the non-empty k-wise intersections of the filtration’s cover elements were ε-interleaved with 0 and proved a tight bound on the bottleneck distance between the persistence diagrams of the filtered simplicial complex and the nerve filtration, linear with respect to dimension and ε. We consider a more general cover assumption—that we have an arbitrary cover filtration consisting of simplicial complexes which collectively cover a filtered simFigure 1: A bump in R and subsets with noncontractible intersection.
Leveraging Blockchain to Improve Clinical Decision Support Systems

Clinical decision support systems (CDSS) fail to reduce medical errors because they are unable to interact actively with various sections of the electronic health records (EHR) and provide context-appropriate alerts. The shortcomings of the CDSS increase the cognitive burden to clinicians, worsen alert fatigue, and increases the duplication of tests and health care costs without improving patient outcomes. An architectural framework that leverages together CDSS with a blockchain platform and smart contracts can provide a convenient abstraction that has the potential to solve this problem. We performed a literature search using the keywords CDSS, EHRs, blockchain technology. We manually and electronically looked at papers that were published from 2000-2018. We used CDSS, blockchain, EHR as keywords using the PubMed and Medline databases. The search returned 2338 articles which we narrowed down to 73 manuscripts that were relevant to our research identifying the gaps in the current EHR and CDSS environment. This paper identifies the shortcomings of the current CDSS and propose an architectural framework of a CDSS that utilize blockchain technology with smart contracts that interacts well with clinical workflow, reduces the cognitive burden to the clinician, eliminates irrelevant alerts, duplicate tests, and improves patient outcomes. The proposed architectural framework is designed with the goal of provisioning holistic information at the point of care thereby empowering the physicians with an integrated CDSS which holds the potential to reduce physician burnout, reduce healthcare costs, and improve patient outcomes. We use the STARR format for this research study.
OF NUMERICAL SCHEMES AND BOUNDARY CONDITIONS APPLIED TO WAVE PROPAGATION PROBLEMS

As a review framework, the present study describes the application and performance of different numerical schemes for Computational Aeroacoustics (CAA) of simple wave propagation problems. The current approach aims to simulate pulse propagation on the near field by the use of different spatial and temporal numerical schemes for the full and Linearized Euler Equations (LEE) in a dimensional and dimensionless formulation. Comparisons of processing time, residual error and quality of results are present and discussed shedding light to the relevant parameters which play important role in aeroacoustics. The investigation is focused on different Gaussian pulse propagation cases in unbounded and bounded domains which is solved by using optimized spatial and temporal schemes for reducing dissipative and dispersive errors. The numerical results are compared with the exact analytical solutions when available, showing good agreement.
1 E-Definitions : Review , Rethink And Redefine

E-business and e-commerce are commonly used to describe business ventures and activities that make use of computing and telecommunication technologies, especially those related to the use of the Internet. However, despite widespread use of these terms, there are no generally accepted definitions of them. This paper reviews contemporary definitions of e-business and e-commerce and examines problems of these definitions. A new valuecentric approach is proposed to redefine e-business and ecommerce. Examples of e-business and e-commerce organizations are provided to illustrate this new approach. Implications of the new approach to practitioners and potential research opportunities based on the new approach are discussed.
Paper and Pencil Interactive Storytelling Based on Generic Hand-drawn Sketches

Storytelling has been playing an important role in the culture of many societies. The advent of new technologies and the emergence of the first interactive narratives transformed the traditional stories into a new form of entertainment. In this context, Lima et al [9] proposed recently a new form of Interactive Storytelling called Paper and Pencil Interactive Storytelling, where stories are presented in augmented reality over conventional sheets of paper and users can interact with the virtual characters by sketching objects on the paper. In the present work, we aim to expand the Paper and Pencil Interactive Storytelling system by improving its repertory of identifiable drawings. We propose a new type of user interaction based on scenario changes, which involves two new classes of recognizable drawings: (1) environmental objects, which are used to directly modify the environment of the virtual world; and (2) climate objects, which are used to cause weather changes in the environment. The main objective of this paper is to present a new method for the recognition of generic hand-drawn sketches and their subsequent conversion into 3D objects in the augmented reality environment of the Paper and Pencil Interactive Storytelling system.

Dual Decision Processes: Retrieving Preferences When Some Choices Are Automatic

Evidence from the cognitive sciences suggests that some choices are conscious and reflect individual volition, while others tend to be automatic. Under these circumstances, standard economic modeling might not always be applicable because not all choices are the result of individual tastes. We propose a behavioral model that can be used in standard economic analysis that formalizes the way in which conscious and automatic choices arise. We then present a novel method capable of identifying a set of conscious choices from observed behavior and discuss its usefulness as a framework for studying asymmetric pricing and empirical puzzles in different settings.

Economic impact of traumatic spinal cord injuries in the United States

Individuals having sustained traumatic spinal cord injury (TSCI) in the United States are living longer as compared to historical trends, thanks to an ever-evolving understanding of the nature of this injury. Despite this, multiple barriers to care for TSCI patients remain including variations in government-issued veteran insurance, privatized insurance, and among uninsured individuals. The United States alone experiences 12,000 new TSCI cases every year, many of these are found to occur in a growing proportion of elderly individuals. It is crucial to understand both the short-term direct costs as wells as the long-term rehabilitation costs required by these TSCI patients. The lifetime financial burden for those having sustained a TSCI can be immense for patients, insurance companies, and hospital systems alike. Among those with TSCI, re-hospitalization rates are high, leading to increased healthcare resource utilization within this specific patient population. Costs can quickly balloon into hundreds of thousands of dollars and cause a profound financial burden for these patients. This review article seeks to communicate an understanding of the current financial landscape surrounding TSCI patients. The authors will also examine the costs of acute emergency room surgical care such as American spinal injury association grade, hospital length of stay, as well as the timing delay between injury and surgical decompression. Long-term costs associated with TSCI such as rehabilitation, care of secondary comorbidities, and post-injury employment prospects will be examined as well. These costs will be framed from the patient’s perspective as well as from both the hospital and insurance company’s perspectives. It is hoped a complete understanding as to what makes TSCI such a medically and financially burdensome injury will allow for improved healthcare resource utilization in this population.
Safety Assessment of Bollgard II ® Cotton Event 15985

Bollgard II cotton event 15985 was developed by Monsanto Company to produce the Cry2Ab2 insect control protein, which provides effective season-long control of key lepidopteran insect pests. This product was produced by re-transformation of Bollgard cotton event 531, which produces the CrylAc insect-control protein and the NPTII selectable marker protein. Therefore, Bollgard II cotton produces two proteins for effective control of the major lepidopteran insect pests of cotton, including the cotton bollworm, tobacco budworm, pink bollworm, and armywonn. Bollgard II cotton also produces the P-D-glucuronidase (GUS) marker protein. In addition, Bollgard II cotton provides a more effective insect resistance management program compared to single gene products.
Rate Derivatives and Volatility

Interest rate volatility (IRV) affects a wide base of individuals, investors, companies, and even governments. Individuals who have borrowed through adjustable-rate retail products, such as student loans and mortgages, are susceptible to greater uncertainty about the magnitude of their liabilities from one payment period to the next when short-term interest rates are volatile. For individual and institutional investors in fixed-income products like corporate bonds and mortgage-backed securities, IRV translates directly into undesirable, and sometimes devastating, portfolio volatility. Routine issuers of debt, such as financial institutions, corporations, and governmental agencies, are also forced to deal with the impact of IRV on their vital funding decisions. As with other asset classes, IRV trading resides in the domain of interest rate derivative (IRD) markets. However, unlike volatility trading in spot instruments such as equity indexes, commodities, and currency cross rates, fixed-income assets and derivatives require significantly different mathematical treatments to address added complexities such as annuities and credit risk to name a few. This chapter aims to equip the reader with a foundational understanding of the vast IRD market and the quantitative tools for measuring and managing IRV. Section 20.2 provides perspective on the immensity of over-the-counter (OTC) and listed IRD markets and gives context to how IRV affects market participants. Section 20.3 introduces notation and foundational concepts required to understand various IRD contracts and their risks. Section 20.4 surveys a portion of the large literature on IRD pricing methodologies to the extent relevant to the subject of IRV. Section 20.5 reviews existing volatility trading practices, introduces model-free option-based volatility measures for various interest rates, and covers recent developments in the standardization of IRV trading. Section 20.6 concludes. A technical appendix contains additional details aiming to make the chapter as self-contained as possible.
EFFECTIVENESS OF THE ANGER MANAGEMENT SKILLS TRAINING ON HAPPINESS AND DIMENSIONS OF PSYCHOLOGICAL WELL-BEING OF FEMALE STUDENTS *

This study aims to investigate the effectiveness of anger management skills training on the happiness and psychological well-being of the female students in junior schools supported by the Khomeini Relief Committee in Rudsar County. This is a quasi-experimental study with posttest and pretest and the control group. The statistical population includes all the female students of the junior school supported by the Khomeini Relief Committee in Rudsar County in educational year of 2004-2005. The statistical sample included 30 people, achieved the lower score in the questionnaire of the happiness and psychological well-being and was randomly divided into two groups of control and treatment, each of 15. Oxford Happiness Questionnaire and Reef Psychological well-being questionnaire were used in this study as the research too. Findings and covariance analysis showed that the anger management skills' training has no effect on the happiness of the female students of junior school supported by the Khomeini Relief Committee; and this hypothesis was rejected. Furthermore, concerning other hypotheses, the effect of anger management skills training on psychological well-being and its two subscale of positive relationships with others and selfacceptance in the treatment group was positive and significant and was confirmed; however, there was no significant difference concerning the subscale of environmental mastery. Consequently, anger management skills' training increases the psychological well-being, improve the positive relationships with others and self-acceptance of the female students in junior schools supported by the Khomeini Relief Committee.
Real-time Auditory Contrast Enhancement

Every day, we rely on the information that is encoded in the auditory feedback of our physical interactions. With the goal to perceptually enhance those sound characteristics that are relevant to us — especially within professional practices such as percussion and auscultation — we introduce the method of real-time Auditory Contrast Enhancement (ACE). It is derived from algorithms for speech enhancement as well as from the remarkable sound processing mechanisms of our ears. ACE is achieved by individual sharpening of spectral and temporal structures contained in a sound while maintaining its natural gestalt. With regard to the targeted real-time applications, the proposed method is designed for low latency. As the discussed examples illustrate, it is able to signiﬁcantly enhance spectral and temporal contrast.
Residual Motion Compensation in ECG-Gated Cardiac Vasculature Reconstruction

Generating 3-D reconstructions of cardiac vasculature from angiographic C-arm CT (rotational angiography) data is a challenging problem. Currently, many approaches depend on a reconstruction from ECG-gated projection data either as a reference for further processing or as the final result. Due to imperfect gating, e.g. caused by irregular heart movement, residual motion corrupts these reconstructions. We present an algorithm to compensate for this residual motion. The approach is based on a deformable 2-D–2-D registration between the acquired projection data and a forward projection of the initial ECG-gated reconstruction. It does not depend on an explicit segmentation of vasculature or markers, and works without user interaction. The estimated 2-D deformation field is compensated for in the backprojection step of a subsequent reconstruction. The algorithm is evaluated on two clinical datasets, showing a clear decrease in artefact level and better visibility of structure in the compensated reconstructions.
