Modeling the Player
Authors: Konert Johannes , Gutjahr Michael , Göbel Stefan , Steinmetz Ralf
Published: October 2014

For adaptation and personalization of game play sophisticated player models and learner models are used in game-based learning environments. Thus, the game flow can be optimized to increase efficiency and effectiveness of gaming and learning in parallel. In the field of gaming still the Bartle model is commonly used due to its simplicity and good mapping to game scenarios, for learning the Learning Style Inventory from Kolb or Index of Learning Styles by Felder and Silverman are well known. For personality traits the NEO-FFI (Big5) model is widely accepted. When designing games, it is always a challenge to assess one player's profile characteristics properly in all three models (player/learner/personality). To reduce the effort and amount of dimensions and questionnaires a player might have to fill out, we proved the hypothesis that both, Learning Style Inventory and Bartle Player Types could be predicted by knowing the personality traits based on NEO-FFI. Thus we investigated the statistical correlations among the models by collecting answers to the questionnaires of Bartle Test, Kolb LSI 3.1 and BFI-K (short version of NEO-FFI). A study was conducted in spring 2012 with six school classes of grade 9 (12-14 year old students) in two different secondary schools in Germany. 74 students participated in the study which was offered optionally after the use of a game-based learning tool for peer learning. We present the results statistics and correlations among the models as well as the interdependencies with the student's level of proficiency and their social connectedness. In conclusion, the evaluation (correlation and regression analyses) proved the independency of the models and the validity of the dimensions. Still, especially for all of the playing style preferences of Bartle's model significant correlations with some of the analyzed other questionnaire items could be found. As no predictions of learning style preferences is possible on the basis of this studies data, the final recommendation for the development of game-based learning application concludes that separate modeling for the adaptation game flow (playing) and learn flow (learning) is still necessary.

Authors: Quick John M. , Atkinson Robert K.
Published: October 2014

The purpose of this study was to investigate the relationships between gameplay enjoyment, gaming goal orientations, and individual characteristics. A total of 301 participants were surveyed and the data were analyzed using structural equation modeling. This led to an expanded Gameplay Enjoyment Model (GEM) with 41 game design features that influence player enjoyment. Furthermore, a 3x2 Gaming Goal Orientations model was established with six dimensions that describe players' motivations for gaming. In addition, players' individual characteristics were used to predict gameplay enjoyment in the GEM-Individual Characteristics model. The six Gaming Goal Orientations dimensions were the strongest predictors, while the commonly used gender and hours played per week variables failed to predict enjoyment. The results of this study enable important work to be conducted surrounding gameplay experiences and individual characteristics. Ultimately, it is believed that the Gameplay Enjoyment Model, Gaming Goal Orientations, and the GEM-Individual Characteristics model will be useful tools for researchers and designers who seek to create effective gameplay experiences that meet the needs of players.

Authors: Poulymenopoulou M. , Malamateniou F. , Vassilacopoulos G.
Published: October 2014

A number of recent studies have showed that early and specialized pre-hospital patient management contributes significantly to emergency case survival. Along with the deployment and availability of appropriate emergency care resources, this also requires the availability of timely and relevant patient information to emergency medical service professionals. However, current healthcare information systems are characterized by heterogeneity and fragmentation, hindering emergency care professionals to have access to holistic or integrated patient information from the various organizations that participate in emergency care processes where and when needed. At the same time, many e-health programs have been undertaken worldwide in the area of emergency and unscheduled care with the objective to facilitate sharing of electronic patient information that may be considered important for the delivery of high quality emergency care and, hence, need to be readily available. In this vein, this paper takes a holistic view of the information needed in emergency healthcare and focuses on developing an appropriate tool for providing timely access to holistic care information by authorized users while retaining existing investments. Thus, a special purpose document management mechanism (DMM) is proposed that facilitates creating standardized XML documents from existing healthcare systems and that enables access to such documents at the point of care. For illustrative purposes, the mechanism has been incorporated into a prototype, cloud-based holistic EMS system.

Authors: De Soumya , Stanley R. Joe , Cheng Beibei , Antani Sameer , Long Rodney , Thoma George
Published: October 2014

Images in biomedical publications often convey important information related to an article's content. When referenced properly, these images aid in clinical decision support. Annotations such as text labels and symbols, as provided by medical experts, are used to highlight regions of interest within the images. These annotations, if extracted automatically, could be used in conjunction with either the image caption text or the image citations (mentions) in the articles to improve biomedical information retrieval. In the current study, automatic detection and recognition of text labels in biomedical publication images was investigated. This paper presents both image analysis and feature-based approaches to extract and recognize specific regions of interest (text labels) within images in biomedical publications. Experiments were performed on 6515 characters extracted from text labels present in 200 biomedical publication images. These images are part of the data set from ImageCLEF 2010. Automated character recognition experiments were conducted using geometry-, region-, exemplar-, and profile-based correlation features and Fourier descriptors extracted from the characters. Correct recognition as high as 92.67% was obtained with a support vector machine classifier, compared to a 75.90% correct recognition rate with a benchmark Optical Character Recognition technique.

Authors: Güldenpfennig Florian , Reitberger Wolfgang , Ganglbauer Eva , Fitzpatrick Geraldine
Published: October 2014

The potential of mobile devices to support learning has been explored for some time; however, little attention has been paid to arts education and the active creation of content on mobile devices as a facilitator of learning experiences. Further, new features of mobile phones such as dual cameras open new possibilities for supporting learning in creative contexts. In this paper, the authors investigate ‘duography', a novel kind of ‘two-sided' photography, for mobile phones in an art class. The study involves 17 adolescents, and their art teacher, over the course of 12 weeks. The objective is to convey creative competencies by means of the affordances of new mobile phones. The authors analyse a rich set of student created ‘two-sided photos' to unpack the potential of this novel learning tool for technology-mediated art education. The authors illustrate how duography can mediate creative engagement by providing a frame for reflective discussions and negotiations on different perspectives and multiple meanings of artefacts. The authors conclude with a set of strategies for designing mobile teaching tools for arts education.

How Do Groups Matter?
Authors: Chang Bau-Jung , Chen Yu-Pin
Published: October 2014

The purpose of this study is to examine the relationship between competitive responses and performance, subject to environmental dynamism and strategic action types, to understand competitive responses under moderating effects. This study employed a structured content analysis of coding data from multiple sources and collected competitive actions and responses for the period between 1999 and 2011 in the Taiwanese banking industry. The results show that response likelihood, response imitation and response speed are positively associated with firm performance and that environmental dynamism weakens the relationships among firm performance, response likelihood and response speed. Furthermore, the intensity of strategic action strengthens the relationship between response imitation and firm performance. This study first investigates the roles of environmental dynamism and action types on the relationship between competitive response characteristics and firm performance. This study considers not only the impact of individual firms' responses on their performance but also the impact of collective actions taken by other firms, thus providing new insights in competitive dynamics research.

Published: October 2014

Outsourcing plays an important role in the success of organizations. One of the risks associated with outsourcing is inappropriate contractor selection which significantly influences the implementation of projects in terms of time, quality, and cost. In this study, we applied multi-criteria decision-making techniques in order to determine the best contractor using criteria such as reputation, offered price, and technical capacity. This study is primarily aimed at identifying important criteria of contractor selection, determining the significance of the criteria, and designing a framework for selection of the most appropriate contractor. Important criteria for selecting contractors were extracted from the literature and experts' views were collected using questionnaire. Accordingly, six criteria were selected and their weights were determined by the application of goal programming. Finally, contractors were ranked and the best contractor was selected using fuzzy ELECTRE technique with trapezoidal fuzzy numbers.

Natural Resource Management (NRM) in Australia is socially and ecologically complex, uncertain and contested. Government and non-government stakeholders act and collaborate in regionally-based, multi-scale NRM governance situations, but imbalances in power and breakdowns in trust constrain transparency and equity. Here, we report on an action research project exploring the potential of social learning to contribute to systemic change in multi-governance situations. We sought to understand practices and institutional arrangements in two regional NRM governance case studies in southern Victoria, Australia. Drawing on this research, we explore how social learning, with its foundation of systems thinking, has enabled improved collaborative processes and adaptive governance to emerge.
Improving the Quality of Linked Data Using Statistical Distributions
Authors: Paulheim Heiko , Bizer Christian
Published: October 2014

Linked Data on the Web is either created from structured data sources (such as relational databases), from semi-structured sources (such as Wikipedia), or from unstructured sources (such as text). In the latter two cases, the generated Linked Data will likely be noisy and incomplete. In this paper, we present two algorithms that exploit statistical distributions of properties and types for enhancing the quality of incomplete and noisy Linked Data sets: SDType adds missing type statements, and SDValidate identifies faulty statements. Neither of the algorithms uses external knowledge, i.e., they operate only on the data itself. We evaluate the algorithms on the DBpedia and NELL knowledge bases, showing that they are both accurate as well as scalable. Both algorithms have been used for building the DBpedia 3.9 release: With SDType, 3.4 million missing type statements have been added, while using SDValidate, 13,000 erroneous RDF statements have been removed from the knowledge base.

Published: October 2014

This paper discusses a method for supporting blackboard based lectures. In this method, students watch the video of the blackboard based lecture on a tablet computer. Some parts of the blackboards are recorded by two or more cameras, and a player is designed to enable the students to view and listen to any portion of the lecture. The videos in our method must be high resolution and high quality so that students are able to identify the characters written on the blackboard. However, when many students receive the video by wireless LAN, the bandwidth available for each student decreases. We attempt to maintain the image quality of the video by decreasing the frame rate.

Published: October 2014

This article described the technical progress of the wall insulation organic materials and analyzed other relevant factors in recent years about the insulation materials policies changes and market changes. Through the above description and analysis, we presented new ideas of the future direction of development of organic insulation materials.
Background
In recent years, big fire moments remind the importance of fire safety all the time. The CCTV Building Fire in 2009, Shanghai Jiaozhou Road Fire in 2010 and Shijingshan Fire in 2013, let the public turn pale at the mention of a word about fire. These fires are all related to the wall insulation organic materials. In fact, it should be said that unqualified exterior wall thermal insulation materials and the lack of supervision measures led to a variety of fire accidents which can be avoided. Therefore, good flame retardant wall insulation organic materials and thermal insulation system are very important to reduce and prevent fire, and they are also fundamentally important ways to block and reduce the fire risk.
At present, there are three kinds of wall insulation materials. The first type are the inorganic heat preservation materials, such as rock wool, glass wool, mineral slurry, etc., These materials belong to no combustible materials (class A fire), and there is no fire safety problems. The second type of wall insulation materials are composite materials, such as phenolic foam insulation materials, reaching flame retardant materials B1 level (fire). The third kind are the organic polymer insulation materials, such as molding benzene board (EPS), foaming benzene board (XPS), polyurethane (PU) . They belong to the combustible materials (B2 fire). This kind of material have the danger of fire. In our country the most widely used of wall insulation materials are the third class. Especially the EPS and XPS have good heat preservation performance, low price. And They are light and durable. But, this kind of materials have obvious disadvantages that they are so easy to burn, and release diffuse toxic or harmful gas in the combustion. Therefore, we should focus on hot spots about organic fire situation of wall insulation organic materials.
