Trust in Online Technology: Towards Practical Guidelines Based on Experimentally Verified Theory
Authors: Christian Detweiler, Joost Broekens
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

A large amount of research attempts to define trust, yet relatively little research attempts to experimentally verify what makes trust needed in interactions with humans and technology. In this paper we identify the underlying elements of trust-requiring situations: (a) goals that involve dependence on another, (b) a perceived lack of control over the other, (c) uncertainty regarding the ability of the other, and (d) uncertainty regarding the benevolence of the other. Then, we propose a model of the interaction of these elements. We argue that this model can explain why certain situations require trust. To test the applicability of the proposed model to an instance of human-technology interaction, we constructed a website which required subjects to depend on an intelligent software agent to accomplish a task. A strong correlation was found between subjects' level of trust in the software and the ability they perceived the software as having. Strong negative correlations were found between perceived risk and perceived ability, and between perceived risk and trust.
Extracting Structured Data from Ajax Site
Authors: Tian Xia
Venue: Proceedings of the 2009 First International Workshop on Database Technology and Applications (2009)

Ajax is an important approach for improving rich interactivity between web server and end users during Web 2.0 eras. At the same time, the structured data in AJAX web pages can not be extracted easily due to its asynchronous loading. In this paper, we propose a technique for extracting the structured data from the AJAX based web pages. Firstly, an AjaxFetcher component is created to fetch the dynamic page content by using an embedded browser. Secondly, two different strategies are used to extract the structured data from the obtained page contents. Especially for the page that contains multi-records, an automatic approach to determine each possible record is proposed. Experimental results show that fetching Ajax pages and extracting the structured data from them is feasible.
On the interaction of metonymies and anaphora
Authors: Katja Markert, Udo Hahn
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

From the analysis of naturally occurring texts we obtained evidence for the systematic interaction between nominal anaphora and metonymies. This leads us to postulate an integrated model incorporating both phenomena simultaneously. The consideration of discourse constraints for metonymy resolution allows us to challenge the commonly held view that the interpretation of metonymies should proceed from a literal-meaning-first approach. Thus, we argue for an equally balanced treatment of literal and figurative language use.
Evaluating Design Concepts to Support Informal Communication in Hospitals through the Development of a Tool Based on an Iterative Evaluation
Authors: David A. Mejia, Alberto L. Morán, Jesus Favela, Sergio F. Ochoa, José Pino
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

The evaluation of groupware systems is considered a complex activity, mainly due to the impact that this kind of tools could have in work practices, the multiples variables that influences the use and evaluation of them, as well as the expensive cost of time and resources required for an in situ evaluation. These reasons have complicated the generation of a generic guide for evaluating this type of tools. Some researchers in groupware evaluation have highlighted the need to evaluate groupware tools, according to the context and characteristics of those organizations in which these tools would be deployed. Thus, in this paper we present a process to evaluate a tool that supports informal collaboration in hospital. Due to nature of hospital work and the difficulty of performing an in situ evaluation, our proposal implies a multi-phase evaluation process through the development lifecycle of the tool.
Cryptographic Combinatorial Securities Exchanges
Authors: Christopher Thorpe, David C. Parkes
Venue: Financial Cryptography and Data Security: 13th International Conference, FC 2009, Accra Beach, Barbados, February 23-26, 2009. Revised Selected Papers (2009)

We present a useful new mechanism that facilitates the atomic exchange of many large baskets of securities in a combinatorial exchange. Cryptography prevents information about the securities in the baskets from being exploited, enhancing trust. Our exchange offers institutions who wish to trade large positions a new alternative to existing methods of block trading: they can reduce transaction costs by taking advantage of other institutions' available liquidity, while third party liquidity providers guarantee execution--preserving their desired portfolio composition at all times. In our exchange, institutions submit encrypted orders which are crossed, leaving a "remainder". The exchange proves facts about the portfolio risk of this remainder to third party liquidity providers without revealing the securities in the remainder, the knowledge of which could also be exploited. The third parties learn either (depending on the setting) the portfolio risk parameters of the remainder itself, or how their own portfolio risk would change if they were to incorporate the remainder into a portfolio they submit. In one setting, these third parties submit bids on the commission, and the winner supplies necessary liquidity for the entire exchange to clear. This guaranteed clearing, coupled with external price discovery from the primary markets for the securities, sidesteps difficult combinatorial optimization problems. This latter method of proving how taking on the remainder would change risk parameters of one's own portfolio, without revealing the remainder's contents or its own risk parameters, is a useful protocol of independent interest.
An Energy Efficient MAC Protocol for WSNs
Authors: Zheng Guan, Dongfeng Zhao
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Polling as one kind of the TDMA medium access control protocols has the advantage of energy conservation, however, its extensibility is not as good as that of contention-based protocol. The controllable threshold polling medium access protocol (CTP-MAC) in this paper is designed to realize the self-organizing in slot assignment and synchronization. Methods of the imbedded Markov-chain theory and the probability generating function are used to propose an analysis model of energy efficient for wireless sensor network. Mathematic analyses are compared with the simulations results.
Modeling contextual factors of click rates
Authors: Hila Becker, Christopher Meek, David Maxwell Chickering
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 2 (2007)

In this paper, we develop and evaluate several probabilistic models of user click-through behavior that are appropriate for modeling the click-through rates of items that are presented to the user in a list. Potential applications include modeling the click-through rates of search results from a search engine, items ranked by a recommendation system, and search advertisements returned by a search engine. Our models capture contextual factors related to the presentation as well as the underlying relevance or quality of the item. We focus on two types of contextual factors for a given item; the positional context of the item and the quality of the other results. We evaluate our models on a search advertising dataset from Microsoft's Live search engine and demonstrate that modeling contextual factors improves the accuracy of click-through models.
Accessing User Information for Use in Design
Authors: Chris Mcginley, Hua Dong
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Addressing Diversity. Part I: Held as Part of HCI International 2009 (2009)

This paper investigates the issue of accessibility of data and end user information in a typical design development project, the barriers that exist, and how relevant user information might be presented through ergonomic data tools. The barriers typically include a combination of financial outlet, time expenditure and lengthy sourcing of suitable user groups, all of which could be reduced through effective use of tools. Ergonomics information and data useful for `inclusive' design outputs can be underused in design development at a professional level. This study reports on tool concept development and a co-design workshop, which were carried out as part of ongoing research into effective communication of user data to designers in more human and engaging ways.

Authors: Chunsheng Song, Yefa Hu, Zude Zhou
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

The magnetic suspension isolator is designed. The vibration isolation system supported by magnetic suspension and ordinary vibration isolators’ series structure and its equivalent model are established. Taking the system as research subject, the dynamic mathematic expression of the system is established. Equivalent stiffness and damping are obtained .Base on the expression, semi-active output feedback mode fuzzy controller is designed for the isolation system. Then, the appropriate current and optimal stiffness of magnetic suspension isolator could be obtained. Under complex-frequency exciting signal and shock exciting signal are simulated. The simulation results indicate that the isolation performance and shock resistance characteristic of magnetic suspension supporting isolation system with semi-active mode fuzzy control method are more effective in vibration isolation in comparison with the passive system.
Registration for 3-D point cloud using angular-invariant feature
Authors: Jun Jiang, Jun Cheng, Xinglin Chen
Venue: Neurocomputing (2009)

This paper proposes an angular-invariant feature for 3-D registration procedure to perform reliable selection of point correspondence. The feature is a k-dimensional vector, and each element within the vector is an angle between the normal vector and one of its k nearest neighbors. The angular feature is invariant to scale and rotation transformation, and is applicable for the surface with small curvature. The feature improves the convergence and error without any assumptions about the initial transformation. Besides, no strict sampling strategy is required. Experiments illustrate that the proposed angular-based algorithm is more effective than iterative closest point (ICP) and the curvature-based algorithm.
Characteristics of Coupled Solitary Waves in Nerve Impulse Transmission with Dissipation
Authors: Jinli Wang, Jianfeng Hu
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 02 (2009)

Solitary wave is a traveling wave of pulse shape and can travel long distances with little loss of energy or structure. In this letter, characteristics of solitary waves in nerve impulse transmission with high speed are studied. Nonlinear coupling of solitary waves in the presence of dissipation of neurotransmitter is considered in the framework of the coupled nonlinear Schrödinger equations. Interaction between the coupled solitary waves in the different and same position is analyzed; the influence of dissipation on the interaction is investigated; the transmission property for the uncoupled nerve impulses is discussed briefly. Research shows that the principle of solitary wave can explain some transmission features of nerve impulse and may provide certain theory reference and model for applying solitary wave to the deep exploration into nerve impulse transmission.
Dynamic Simulation of Vehicle Floating Bridge System Based on ADAMS
Authors: Yu-huai Hou, Fang-zhen Song, Ru-jian Ma
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Mathematic model of floating bridge elastic base infinite beam is established. The vehicle is simplified as moving mass and moving vibration mass respectively, and dynamic responses of floating bridge under the action of vehicle are studied. The three-dimensional vehicle - floating bridge model is established in the ADAMS/View. By using of its powerful solver, the dynamic responses of continuous hinged floating bridge under the action of the two vehicle models are studied. The results show that the vibration characteristics of vehicle have a great influence on the hinged force, the hinged force when considering the vehicle as moving vibration mass account for 62.75% of the hinged force when considering the vehicle as moving mass. The contact forces between the vehicles and the floating bridge also have great differences corresponding to the two vehicle models. Due to the moving vibration mass model is closer to the actual condition, it is necessary to consider the vibration characteristics of vehicle in the analysis of vehicle - floating bridge dynamic responses.
Caste Structures and E-Governance in a Developing Country
Authors: Rahul De'
Venue: Proceedings of the 8th International Conference on Electronic Government (2009)

Castes, or endogamous kinship relationships, are prevalent in communities across the world and particularly in developing countries. Caste plays a strong role in determining community structures and political power. However, the role of caste as a factor in shaping e-governance design and outcomes is absent in the literature. This paper addresses this particular gap by examining some cases from India.The paper specifically considers whether the priorities of dominant caste groups determine e-governance design and implementations, to the exclusion of marginal and non-dominant castes. Further, it examines if e-governance introductions change or affect the relations of caste groups. The research relies on Structuration theory to provide a framework through which to study these issues. Data from three case studies from India are used to conduct the analysis, and these include the Bhoomi project from Karnataka, the Gyandoot project from Madhya Pradesh, and the VKC project from Puducherry. All three are information kiosk-based projects for providing e-governance services for citizens living in villages and rural areas.
Evolutionary Game Analysis on the Accounting Information Distortion by Listed Companies
Authors: Fangyuan Lu, Bingxian Qiu, Yunfei Fan
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

This paper analyzed the behavior of strategy-selecting in interaction among Certified Public Accountants, the listed companies and regulatory authorities in market with the evolutionary game theory. The result shows that if the gain for producing distorted accounting information by listed companies is larger than the loss of being discovered and punished by regulatory authorities, or the supervising cost of regulatory authorities is too high, the distorted accounting information emerge inevitably; enforcing the punishment on listed companies and delinquent Certified Public Accountants for their producing distorted accounting information, containing their motive of producing distorted accounting information, are all the important ways to eliminate distorted accounting information provided by listed companies.
Introduction

Venue: Proceedings of the 15th International Euro-Par Conference on Parallel Processing (2009)

Scheduling and load balancing are key components of any resource management system. They are responsible for making the best use of available resources by planning, allocating and redistributing computational tasks onto these resources. Typical optimization criteria are theminimization of execution times and response times. However, additional criteria like power consumption, quality-of-service requirements or even multi-criteria problems have recently been investigated.
An Application of Intelligent Data Analysis Techniques to a Large Software Engineering Dataset
Authors: James Cain, Steve Counsell, Stephen Swift, Allan Tucker
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

Within the development of large software systems, there is significant value in being able to predict changes. If we can predict the likely changes that a system will undergo, then we can estimate likely developer effort and allocate resources appropriately. Within object oriented software development, these changes are often identified as refactorings. Very few studies have explored the prediction of refactorings on a wide-scale. Within this paper we aim to do just this, through applying intelligent data analysis techniques to a uniquely large and comprehensive software engineering time series dataset. Our analysis show extremely promising results, allowing us to predict the occurrence of future large changes.
Haptic Interaction Techniques for Exploring Chart Data
Authors: Sabrina A. Panëels, Jonathan C. Roberts, Peter J. Rodgers
Venue: Proceedings of the 4th International Conference on Haptic and Audio Interaction Design (2009)

Haptic data visualization is a growing research area. It conveys information using the sense of touch which can help visually impaired people or be useful when other modalities are not available. However, as haptic devices and virtual worlds exhibit many challenges, the haptic interactions developed are often simple and limited to navigation tasks, preferring other modalities to relay detailed information. One of the principal challenges of navigation with haptic devices alone, particularly single point-based force-feedback devices, is that users do not know where to explore and thus obtaining an overview is difficult. Thus, this paper presents two types of interaction technique that aim to help the user get an overview of data: 1) a haptic scatter plot, which has not been investigated to any great degree, provided by a force model and 2) a new implementation for a haptic line chart technique provided using a guided tour model.
MAS-Based Cooperative Control for Biotechnological Process-A Case Study
Authors: Dariusz Choinski, Mieczyslaw Metzger, Witold Nocon
Venue: Proceedings of the 4th International Conference on Industrial Applications of Holonic and Multi-Agent Systems: Holonic and Multi-Agent Systems for Manufacturing (2009)

The MAS-based control seems to be better suited for manufacturing control because of its discrete event character. Nevertheless, for continuous industrial processes the MAS-based control can be also very attractive. In this paper, a synthesis of the MAS-based control system for the continuous process is presented. A biological reactor is controlled using respirometric approach. In this approach, both standard control loops and additional experiments are performed to obtain measurements not available on-line. Therefore, the system consists of different control agents being able to cooperate or to inhibit each other in order to achieve the appropriate goals. A case study experiments are realized using an experimental wastewater treatment pilot plant.
Compensating for nonstationary blurring by further blurring and deconvolution
Authors: Gengsheng L. Zeng
Venue: International Journal of Imaging Systems and Technology (2009)

In many imaging systems, the point spread function (PSF) is nonstationary. Usually, a computation-intensive iterative algorithm is used to deblur the nonstationary PSF. This article presents a new idea of using a noniterative method to compensate for the spatially variant PSF. This method first further blurs the image with a nonstationary kernel so that the resultant image has a stationary PSF, then deblurs the resultant image using an efficient decovolution technique. The proposed method is illustrated and implemented by single photon emission computed tomography applications. &copy; 2009 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 19, 221&ndash;226, 2009
Operational Semantics for DKAL: Application and Analysis
Authors: Yuri Gurevich, Arnab Roy
Venue: Proceedings of the 6th International Conference on Trust, Privacy and Security in Digital Business (2009)

DKAL is a new expressive high-level authorization language. It has been successfully tried at Microsoft which led to further improvements of the language itself. One improvement is the separation of concerns between static core policies and dynamic workflow; important safety properties can be proved from the core policies alone, independently from the workflow. Another improvement is true decentralization; different principals live in different worlds exchanging information by means of communication and filtering assertions. We also present some complexity results.
Examining the relation between domain-related communication and collaborative inquiry learning
Authors: Anjo Anjewierden, Hannie Gijlers, Bas Kolloffel, Nadira Saab, Robert De Hoog
Venue: Proceedings of the 9th international conference on Computer supported collaborative learning - Volume 1 (2009)

Research has suggested that providing elaborated explanations is often more beneficial for learning than receiving explanations (e.g., Webb, 1989). Applied to chat communication in a collaborate inquiry learning environment, we would expect that in a dyad the learner with more domain-related contributions than his partner would learn more. In the paper we develop a method to examine the relation between domain-related chats and learning outcome for intuitive knowledge. We describe how we automatically extract domain-related messages, and score them based on the expected cognitive effort to produce the messages. The analysis confirms that there is a positive relation between a high score on domain-related chats and the learning improvement as measured by the difference between a post-test and a pre-test on intuitive knowledge.
