Understanding Mass Interactions in Online Sports Viewing

This article aims to deepen understanding of these mass interactions in online sports viewing through studying Naver Sports, the largest online sports viewing service in Korea. We examined the diverse aspects of mass interactions, including interactive experiences, usage motives, and relationships between usage patterns and motives, through analysis of almost 6 million chats from Naver Sports and from self-reporting survey data from 1,123 users. First, we found that online sports viewing provides unique interactive experiences when compared to other settings such as offline sports viewing and social TV viewing with friends. Second, we found the key motives inspiring online sports viewing include the following: sharing feelings/thoughts, wanting to be entertained, sharing information, and wanting to feel membership in a group. Third, these motives were significantly related to specific usage patterns. Finally, we explored how the study’s key findings can offer practical design implications to enhance online sports viewing services, and to show system designers how to support particular usage patterns to better accommodate specific user motives.
Schistosoma mansoni Antigens Modulate Experimental Allergic Asthma in a Murine Model: a Major Role for CD4+ CD25+ Foxp3+ T Cells Independent of Interleukin-10

ABSTRACT In areas where schistosomiasis is endemic, a negative correlation is observed between atopy and helminth infection, associated with a low prevalence of asthma. We investigated whether Schistosoma mansoni infection or injection of parasite eggs can modulate airway allergic inflammation in mice, examining the mechanisms of such regulation. We infected BALB/c mice with 30 S. mansoni cercariae or intraperitoneally injected 2,500 schistosome eggs, and experimental asthma was induced by ovalbumin (OVA). The number of eosinophils in bronchoalveolar lavage fluid was higher in the asthmatic group than in asthmatic mice infected with S. mansoni or treated with parasite eggs. Reduced Th2 cytokine production, characterized by lower levels of interleukin-4 (IL-4), IL-5, and immunoglobulin E, was observed in both S. mansoni-treated groups compared to the asthmatic group. There was a reduction in the number of inflammatory cells in lungs of S. mansoni-infected and egg-treated mice, demonstrating that both S. mansoni infection and the egg treatment modulated the lung inflammatory response to OVA. Only allergic animals that were treated with parasite eggs had increased numbers of CD4+ CD25+ Foxp3+ T cells and increased levels of IL-10 and decreased production of CCL2, CCL3, and CCL5 in the lungs compared to the asthmatic group. Neutralization of IL-10 receptor or depletion of CD25+ T cells in vivo confirmed the critical role of CD4+ CD25+ Foxp3+ regulatory T cells in experimental asthma modulation independent of IL-10.
Enhancing literature Review Methods - towards More Efficient literature Research with Latent Semantic Indexing

Nowadays, the facilitated access to increasing amounts of information and scientific resources means that more and more effort is required to conduct comprehensive literature reviews. Literature search, as a fundamental, complex, and time-consuming step in every literature research process, is part of many established scientific methods. However, it is still predominantly supported by search techniques based on conventional term-matching methods. We address the lack of semantic approaches in this context by proposing an enhancement of established literature review methods. For this purpose, we followed design science research (DSR) principles in order to develop artifacts and implement a prototype of our Tool for Semantic Indexing and Similarity Queries (TSISQ) based on the core concepts of latent semantic indexing (LSI). Its applicability is demonstrated and evaluated in a case study. Results indicate that the presented approach can help save valuable time in finding basic literature in a desired research field or increasing the comprehensiveness of a review by efficiently identifying sources that otherwise would not have been taken into account. The target audience for our findings includes researchers who need to efficiently gain an overview of a specific research field, deepen their knowledge or refine the theoretical foundations of their research.
Goldfish retina: functional polarization of cone horizontal cell dendrites and synapses

In serial electron micrographs we observed that dendrites of goldfish cone horizontal cells are either central or lateral in ribbon synaptic triads, depending on cone and horizontal cell type. The chromatic properties of cone horizontal cell responses may be explained if the cone horizontal cells act as interneurons, receiving from cones through their central processes but acting on cones through their lateral processes.
Student-Centred Assessments and their Impact on Learning - An IS Case Study

In higher education, one can find many different assessment methods ranging from the most traditional examination based assessment to computer-based on-line assessment and many other innovative assessment practices. Yet, achieving a high level of positive impact of assessment on student learning is always a major concern among academic practitioners. Choosing the right set of assessment modes, designing the assessment activities and evaluating their impact on student learning are some of the major challenges. This challenge is more pronounced in the recently emerging Information Systems (IS) programmes as there is an ever-growing wide variety of assessment methods matching with the ever-changing tools and techniques that evolve in the computer hardware and software disciplines. In such a dynamic context, IS courses in higher education are faced with a very short life-cycle and hence do not have the luxury of experimenting different assessment modes from time to time. They need to arrive at the right combination of assessments based on the prevailing situation. It is therefore a question as to which assessment methods are the best to be adopted and what is the impact of such assessments on student learning. This paper proposes a pragmatic four-step student-centred approach to identify and design suitable assessment methods and to examine their impact on student learning. The student-centred approach is illustrated through a study conducted for a particular IS course in a higher education setting. Due to the generic nature of this approach, it could be adopted in courses from other areas as well.
The BigDAWG Polystore System

This paper presents a new view of federated databases to address the growing need for managing information that spans multiple data models. This trend is fueled by the proliferation of storage engines and query languages based on the observation that â no one size fits allâ . To address this shift, we propose a polystore architecture; it is designed to unify querying over multiple data models. We consider the challenges and opportunities associated with polystores. Open questions in this space revolve around query optimization and the assignment of objects to storage engines. We introduce our approach to these topics and discuss our prototype in the context of the Intel Science and Technology Center for Big Data
On the dynamical formation of accreting intermediate mass black holes

ABSTRACT We compute the probability that intermediate mass black holes (IMBHs) cap-ture companions due to dynamical interactions and become accreting sources,and explore the possibility that the accreting IMBHs would appear as ultra-luminous X-ray sources (ULXs). We focus on IMBHs originating from low-metallicity Population III stars. Two channels of IMBH formation are consid-ered: from primordial halos in the framework of hierarchical clustering, andfrom non-mixed, zero-metallicity primeval gas in galactic discs. IMBHs canform binary systems due to tidal captures of single stars and exchange inter-actions with existing binary systems in galactic discs. We ﬁnd that neitherformation mechanism of the accreting IMBH binary is able to provide enoughsources to explain the observed population of ULXs. Even at sub-ULX lu-minosity, the total number of accreting IMBHs with L > 10 36 erg s −1 withdynamically captured companions is found to be < 0.01 per galaxy.Key words: accretion, accretion discs - black hole physics, stars: formation- stars: evolution, galaxies: formation, X-rays: binaries
Does classic school curriculum contribute to morality? Integrating school curriculum with moral and intellectual education

Abstract Phillip Cam recently published a study on the separation between the teaching and learning of classic school curriculum (CSC) on the one hand and morality on the other. He suggests an approach to integrate them. The goal of this article was to suggest a complementary alternative approach, to Cam’s. Based on a MacIntyrean paradigm, I argue that seeing the CSC (such as math, biology, literature and history) as ‘practices’ would also enable that integration. This approach differs from the one proposed by Cam, since it preserves the structure of the CSC. Nevertheless, I will demonstrate how this approach leads to a number of changes in the formation, teaching and learning of school curriculum. As background, I will briefly describe R.S. Peters’ attempt to find an internal justification for the teaching and learning of school curriculum and point to some weaknesses it contains. My proposal can be understood as deriving from the same principle, of another famous educational initiative, Mortimer Adler’s ‘Great Book Project’. Toward the end of the article, I will demonstrate why Adler’s project differs from mine, and why it does not meet the goal of integrating learning school curriculum with moral education.
A Joint Training Framework for Robust Automatic Speech Recognition

Robustness against noise and reverberation is critical for ASR systems deployed in real-world environments. In robust ASR, corrupted speech is normally enhanced using speech separation or enhancement algorithms before recognition. This paper presents a novel joint training framework for speech separation and recognition. The key idea is to concatenate a deep neural network (DNN) based speech separation frontend and a DNN-based acoustic model to build a larger neural network, and jointly adjust the weights in each module. This way, the separation frontend is able to provide enhanced speech desired by the acoustic model and the acoustic model can guide the separation frontend to produce more discriminative enhancement. In addition, we apply sequence training to the jointly trained DNN so that the linguistic information contained in the acoustic and language models can be back-propagated to influence the separation frontend at the training stage. To further improve the robustness, we add more noise- and reverberation-robust features for acoustic modeling. At the test stage, utterance-level unsupervised adaptation is performed to adapt the jointly trained network by learning a linear transformation of the input of the separation frontend. The resulting sequence-discriminative jointly-trained multistream system with run-time adaptation achieves 10.63% average word error rate (WER) on the test set of the reverberant and noisy CHiME-2 dataset (task-2), which represents the best performance on this dataset and a 22.75% error reduction over the best existing method.
Measurement of Spatial Ability: Construction and Validation of the Spatial Reasoning Instrument for Middle School Students

This article describes the development and validation of a newly designed instrument for measuring the spatial ability of middle school students (11-13 years old). The design of the Spatial Reasoning Instrument (SRI) is based on three constructs (mental rotation, spatial orientation, and spatial visualization) and is aligned to the type of spatial maneuvers and task representations that middle-school students may encounter in mathematics and Science, Technology, Engineering and Mathematics (STEM)-related subjects. The instrument was administered to 430 students. Initially, a set of 15 items were devised for each of the three spatial constructs and the 45 items were eventually reduced to 30 items on the basis of factor analysis. The three underpinning factors accounted for 43% of variance. An internal reliability value of . 845 was obtained. Subsequent Rasch analysis revealed appropriate item difficulty fit across each of the constructs. The three constructs of the SRI correlated significantly with existing well-established psychological instruments: for mental rotation (.71), spatial orientation (.41), and spatial visualization (.66). The psychometric characteristics of SRI substantiate the use of this measurement tool for research and pedagogical purposes.
Pain and function in patients after primary unicompartmental and total knee arthroplasty.

BACKGROUND Unicompartmental knee arthroplasty has received renewed interest; however, its short-term advantages over total knee arthroplasty should be weighed against a higher risk of reoperation. Information regarding pain and function after unicompartmental and total knee arthroplasty is therefore needed. METHODS Patient-reported data regarding pain and function were collected, at least two years postoperatively and by way of postal questionnaire, from 1344 patients who were listed on the Norwegian Arthroplasty Register as having had an unrevised primary total knee arthroplasty (972 patients) or a unicompartmental knee arthroplasty (372 patients) for the treatment of arthritis. Outcomes were assessed (with a score of zero indicating the worst possible outcome and a score of 100 indicating the best possible outcome) with use of the five subscales from the Knee Injury and Osteoarthritis Outcome Score, the scores from visual analog scales regarding degree of pain and satisfaction with the surgery, and the change in index score (from preoperative to postoperative) on the EuroQol-5D health-related quality-of-life instrument. We also used all forty-two questions from the Knee Injury and Osteoarthritis Outcome Score as outcome measures. To be regarded as clinically significant, the differences needed to be eight units for the Knee Injury and Osteoarthritis Outcome Score outcomes, ten units for the pain and satisfaction scales, and 0.4 unit for the detailed Knee Injury and Osteoarthritis Outcome Score questions. RESULTS Unicompartmental knee implants performed better than total knee implants on the Knee Injury and Osteoarthritis Outcome subscales for "Symptoms" (adjusted mean difference, 2.7; p = 0.04), "Function in Daily Living" (adjusted mean difference, 4.1; p = 0.01), and "Function in Sport and Recreation" (adjusted mean difference, 5.4; p = 0.006). Of the forty-two analyses of the detailed questions, four differences were significant. These differences were in favor of unicompartmental knee arthroplasty, but only the question "Can you bend your knee fully? " reached the level of clinical significance. CONCLUSIONS We found only small or no differences in pain and function between the scores, at least two years following surgery, of patients who underwent unicompartmental knee arthroplasty and those of patients who underwent total knee arthroplasty; however, patients with unicompartmental knee implants had fewer problems with activities that involved bending the knee.
The Career Growth of Professional Employees and Turnover Intention:The Moderating Role of Organizational-professional Conflict

This paper researches the impact of career growth and organizational-professional conflict on turnover intention for professional employees,examining how organizational-professional conflict shapes the relationship between career growth and turnover intention.With 215 questionnaires,the empirical results from hierarchical multiple regression shows that the two dimensions of career growth,career goal progress and career capacity development,affect turnover intention negatively;organizational-professional conflict affects turnover intention positively.Organizational-professional conflict moderates the relationship between career growth and turnover intention.Specifically,organizational-professional conflict moderates the relationship among career goal progress,career capacity development and turnover intention.Along with the increase of organizational-professional conflict,the impact of career goal progress and career capacity development on turnover intention becomes weak.
Combining experimental evolution and field population assays to study the evolution of host range breadth

Adapting to specific hosts often involves trade‐offs that limit performance on other hosts. These constraints may either lead to narrow host ranges (i.e. specialists, able to exploit only one host type) or wide host ranges often leading to lower performance on each host (i.e. generalists). Here, we combined laboratory experiments on field populations with experimental evolution to investigate the impact of adaptation to the host on host range evolution and associated performance over this range. We used the two‐spotted spider mite, Tetranychus urticae, a model organism for studies on the evolution of specialization. Field mite populations were sampled on three host plant species: tomato, citrus tree and rosebay (Nerium oleander). Testing these populations in the laboratory revealed that tomato populations of mites could exploit tomato only, citrus populations could exploit citrus and tomato whereas Nerium populations could exploit all three hosts. Besides, the wider niche ranges of citrus and Nerium populations came at the cost of low performance on their non‐native hosts. Experimental lines selected to live on the same three host species exhibited similar patterns of host range and relative performance. This result suggests that adaptation to a new host species may lead to wider host ranges but at the expense of decreased performance on other hosts. We conclude that experimental evolution may reliably inform on evolution in the field.
Acoustical properties of the swimbladder in the oyster toadfish Opsanus tau

SUMMARY Both the swimbladder and sonic muscles of the oyster toadfish Opsanus tau (Linnaeus) increase in size with fish growth making it difficult to distinguish their relative contributions to sound production. We examined acoustics of the swimbladder independent of the sonic muscles by striking it with a piezoelectric impact hammer. Amplitude and timing characteristics of bladder sound and displacement were compared for strikes of different amplitudes. Most of the first cycle of sound occurred during swimbladder compression, indicating that the bladder rapidly contracted and expanded as force increased during the strike. Harder hits were shorter in duration and generated a 30 dB increase in amplitude for a 5-fold or 14 dB range in displacement. For an equivalent strike dominant frequency, damping, bladder displacement and sound amplitude did not change with fish size, i.e. equal input generated equal output. The frequency spectrum was broad, and dominant frequency was driven by the strike and not the natural frequency of the bladder. Bladder displacement decayed rapidly (ζ averaged 0.33, equivalent to an automobile shock absorber), and the bladder had a low Q (sharpness of tuning), averaging 1.8. Sound output of an acoustic source is determined by volume velocity (surface area × velocity), and bladder surface area, muscle dimensions and contraction amplitude increase with fish size. Therefore, larger fish will be capable of producing more intense sound. Because the bladder is a low Q resonator, its output will follow muscle contraction rates independent of its size and natural frequency.
Measuring Player Immersion in the Computer Game Narrative

In order to measure player immersion in the computer game narrative, this study explores and analyzes factors of the computer game narrative that influence players who are immersed in the game story world. Originally a questionnaire consisting of six dimensions—Curiosity, Concentration, Challenge, Control, Comprehension, and Empathy—was proposed. To evaluate the questionnaire, two surveys were conducted on the Internet, and data were collected from 734 respondents. After exploratory factor analysis and confirmatory factor analysis, the dimensions were modified to Curiosity, Concentration, Challenge and Skills, Control, Comprehension, Empathy, and Familiarity.
Deferred shadowing for real-time rendering of dynamic scenes under environment illumination: Image, Colour and Illumination in Animation

Environment illumination, which is a complex and distant lighting environment represented by images, is often applied to create photo-realistic images. However, creating photo-realistic animations under environment illumination is exceedingly compute intensive. The Precomputed Radiance Transfer (PRT) methods achieve real-time rendering under environment illumination; however, these methods only have a limited application in animation because the objects in the scene cannot be moved or rotated. In this paper, we propose a method for rendering photo-realistic animations of dynamic scenes under environment illumination in real time. We notice the fact that when objects are moved or rotated, changes of radiances occur mainly in the regions of shadows cast by other objects. Our method makes a distinction between self-shadow and shadows cast by other objects and computes these two kinds of shadows efficiently. Copyright © 2005 John Wiley & Sons, Ltd.
Optimal placement of controllers in a resilient SDN architecture

The SDN (Software Defined Networking) paradigm brings flexibility to the network management and is an enabler to reduce the energy consumption of the networks. However deploying a set of SDN controllers to manage a Wide Area Network is still a challenge as it implies to determine the right number of controllers to install and their locations within the network. In this paper, we give the key performance criteria that should be taken into account to provide a “good” placement in terms of Quality of Service and we propose an integer linear programming formulation of the resilient controller placement problem. This formulation provides the optimal number of controllers and their location while embedding QoS and load balancing constraints for several level of backup controllers.
Disordered eating and religious observance: a focus on ultra-Orthodox Jews in an adult community study.

OBJECTIVE To broaden the socio-cultural context of eating disturbances by exploring religious observance and its presumed protective role for ultra-Orthodox women. METHOD Detailed telephone interviews with community sample of adult Jewish women in Israel, including 261 ultra-Orthodox. Frequency of 14 symptoms of disordered eating (DEB) assessed. Hierarchical regressions examine predictors of DEB severity within observance categories (ultra-Orthodox, Orthodox, Traditional, and Secular). RESULTS Contrary to expectations, no significant differences were found in the frequency of serious DEB between the most and least religiously observant, ultra-Orthodox, and Secular women. Regressions reveal similar predictors of DEB severity (obesity followed by self-criticism) as well as substantial variations in amount of variance explained. DISCUSSION Apparently, rigorous religious adherence does not protect ultra-Orthodox women from serious eating problems. Additional analyses can inform socio-cultural perspectives by examining the connection between body dissatisfaction and disordered eating in this insular and isolated religious community, whose exposure to secular media is prohibited.
