Testing the spirit of the information age

Every age has a 'spirit," The Information Age seems to be a more extreme case than most eras, with the constant barrage of messages promising social and individual salvation. Information and information technology are heralded as\ud great, new possibilities not just for reform but perfection, with some even predicting the end of physical death (using information technology. by the end of the next century. The intensity of our current period's fascination with technology is partly due to the technology itself-ideas or sales pitches get out to more people more quickly than ever before in history, and, as a result it\ud is easy to be blinded by all the promises and hype. It is no accident that ideas like "ecommerce" and "knowledge management' are unifying concepts for many in this era, but although there is nothing intrinsically wrong with them, there is something amiss with how they are discussed. This essay comments on the latter issue, the hyperbole of the Information Age, from three perspectives: 1) as a consumer of information technology; 2) as an educator in a field (archives and records management) utilizing information technology; and 3) as an individual convinced about the relevancy of basic Judaic-Christian beliefs as one means to shift critically the many conflicting and confusing messages promulgated by the so-called modern Information\ud Age

Efficient Multi-Robot Coverage of a Known Environment

This paper addresses the complete area coverage problem of a known environment by multiple-robots. Complete area coverage is the problem of moving an end-effector over all available space while avoiding existing obstacles. In such tasks, using multiple robots can increase the efficiency of the area coverage in terms of minimizing the operational time and increase the robustness in the face of robot attrition. Unfortunately, the problem of finding an optimal solution for such an area coverage problem with multiple robots is known to be NP-complete. In this paper we present two approximation heuristics for solving the multi-robot coverage problem. The first solution presented is a direct extension of an efficient single robot area coverage algorithm, based on an exact cellular decomposition. The second algorithm is a greedy approach that divides the area into equal regions and applies an efficient single-robot coverage algorithm to each region. We present experimental results for two algorithms. Results indicate that our approaches provide good coverage distribution between robots and minimize the workload per robot, meanwhile ensuring complete coverage of the area.Comment: In proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 201

Is the Heart of Education the Education of the Heart?

If a Christian Institution is to do more than expand the mind or ‘head’ of adherents (which is the reason given from a biblical worldview perspective for a Christian institute’s existence), then how does education become an education of the heart, leading to a transforming world and life view? It is of note that even though Christian institutions are no strangers to the subject of worldview, sparse research has been done concerning worldview as it relates to long term educational impact. This paper is a case for the importance of looking at heart and worldview and a review of some of the literature that points the reader in that direction. Forthcoming research in progress will highlight ways in which one specific Christian institution does or does not live up to the metaphor that the heart of education is the education of the heart

Automated Functional Testing based on the Navigation of Web Applications

Web applications are becoming more and more complex. Testing such applications is an intricate hard and time-consuming activity. Therefore, testing is often poorly performed or skipped by practitioners. Test automation can help to avoid this situation. Hence, this paper presents a novel approach to perform automated software testing for web applications based on its navigation. On the one hand, web navigation is the process of traversing a web application using a browser. On the other hand, functional requirements are actions that an application must do. Therefore, the evaluation of the correct navigation of web applications results in the assessment of the specified functional requirements. The proposed method to perform the automation is done in four levels: test case generation, test data derivation, test case execution, and test case reporting. This method is driven by three kinds of inputs: i) UML models; ii) Selenium scripts; iii) XML files. We have implemented our approach in an open-source testing framework named Automatic Testing Platform. The validation of this work has been carried out by means of a case study, in which the target is a real invoice management system developed using a model-driven approach.Comment: In Proceedings WWV 2011, arXiv:1108.208

The mechanism of the Einstellung (set) effect: A pervasive source of cognitive bias

Copyright @ The Authors 2010The eye movements of expert players trying to solve a chess problem show that the first idea that comes to mind directs attention towards sources of information consistent with itself and away from inconsistent information. This bias continues unconsciously even when the player believes he is looking for alternatives. The result is that alternatives to the first idea are ignored. This mechanism for biasing attention ensures a speedy response in familiar situations but it can lead to errors when the first thought that comes to mind is not appropriate. We propose that this mechanism is the source of many cognitive biases from phenomena in problem solving and reasoning, to perceptual errors and failures in memory

New Media and the Quality of Life

We are currently in the middle of a revolution. This revolution, sometimes called the digital revolution, is the revolutionary transformation brought about in the information and communication structure of society by the advent of the digital computer, with most of the major transformations having taken place in the past thirty years. Digital computing technology has generated the mainframe and personal computer, the multimedia computer, and computer networks. It has also transformed the telephone system and the monetary system, it is transforming all kinds of conventional products ranging from washing machines to automobiles, and it is on its way to change television as well. More than ever, contemporary society is an Information Society, in which the importance of information and communication is much greater than in past societies, and of which technologies that facilitate information and communication processes are a central societal feature. In this paper, I want to evaluate the implications of contemporary information and communication media for the quality of life, including both the new media from the digital revolution and the older media that still remain in use. My evaluation of contemporary media will proceed in three parts. In the section to follow, the benefits of contemporary media will be discussed, with special emphasis given to their immediate functional benefits. The section thereafter is devoted to a discussion of four potential threats posed by contemporary media. In a final major section, I look at the future of digital media and the possibilities available to us in shaping that future. A short concluding section ends the paper
