Questions of ethics: participatory information systems research in community settings
Authors: E. Byrne, P. M. Alexander
Venue: Proceedings of the 2006 annual research conference of the South African institute of computer scientists and information technologists on IT research in developing countries (2006)

It is generally considered the ethical option to consult with the end users and other stakeholders when developing business Information Systems or conducting research in the IS discipline, whether with the express intention of empowering them or simply to include multiple points of view. This is also the 'smart' option as it is a way to improve the probability that the system will be useful, usable, and hence used. There are significant similarities between participants who are employees in an organisation for whom the system is being developed or researched and the case where the system is intended to benefit the public and hence the participants are members of civil society. However, there are ethical concerns regarding participatory research in IS that are more pronounced or have somewhat different aspects in community-based IS than in business IS. Conventional social science research ethics include codes which are largely based on four principles: informed consent; absence of deception; privacy and confidentiality, and; accuracy. However, as most of the literature on participatory research is westernised and based on traditional business IS, there is little discussion on ethical participation in community settings. Numerous different issues arise in such settings and are discussed in the paper. These include the need: to clearly define the roles and functions of the participants; to understand the nature of power sharing between participants; to take cognisance of the cost versus gains from participation; to be aware of domination in decision making; to understand local meaning; to develop the capacity to participate, and; to consider divergent expectations of participants. The previous experience of both authors support these arguments and discussion in this paper, but the objective of the paper is to present a conceptual research methodology discussion rather than an empirical research paper
A fast kernel-based nonlinear discriminant analysis for multi-class problems
Authors: Yong Xu, David Zhang, Zhong Jin, Miao Li, Jing-Yu Yang
Venue: Pattern Recognition (2006)

Nonlinear discriminant analysis may be transformed into the form of kernel-based discriminant analysis. Thus, the corresponding discriminant direction can be solved by linear equations. From the view of feature space, the nonlinear discriminant analysis is still a linear method, and it is provable that in feature space the method is equivalent to Fisher discriminant analysis. We consider that one linear combination of parts of training samples, called ''significant nodes'', can replace the total training samples to express the corresponding discriminant vector in feature space to some extent. In this paper, an efficient algorithm is proposed to determine ''significant nodes'' one by one. The principle of determining ''significant nodes'' is simple and reasonable, and the consequent algorithm can be carried out with acceptable computation cost. Depending on the kernel functions between test samples and all ''significant nodes'', classification can be implemented. The proposed method is called fast kernel-based nonlinear method (FKNM). It is noticeable that the number of ''significant nodes'' may be much smaller than that of the total training samples. As a result, for two-class classification problems, the FKNM will be much more efficient than the naive kernel-based nonlinear method (NKNM). The FKNM can be also applied to multi-class via two approaches: one-against-the-rest and one-against-one. Although there is a view that one-against-one is superior to one-against-the-rest in classification efficiency, it seems that for the FKNM one-against-the-rest is more efficient than one-against-one. Experiments on benchmark and real datasets illustrate that, for two-class and multi-class classifications, the FKNM is effective, feasible and much efficient.
The structure of sets with few sums along a graph

Multiplicative structures in additively large sets
Authors: Mathias Beiglböck, Vitaly Bergelson, Neil Hindman, Dona Strauss
Venue: Journal of Combinatorial Theory Series A (2006)

Previous research extending over a few decades has established that multiplicatively large sets (in any of several interpretations) must have substantial additive structure. We investigate here the question of how much multiplicative structure can be found in additively large sets. For example, we show that any translate of a set of finite sums from an infinite sequence must contain all of the initial products from another infinite sequence. And, as a corollary of a result of Renling Jin, we show that if A and B have positive upper Banach density, then A + B contains all of the initial products from an infinite sequence. We also show that if a set has a complement which is not additively piecewise syndetic, then any translate of that set is both additively and multiplicatively large in several senses.We investigate whether a subset of N with bounded gaps--a syndetic set--must contain arbitrarily long geometric progressions. We believe that we establish that this is a significant open question.
An investigation of children's conceptualisation of computers and how they work
Authors: Michael Hammond, Philip Rogers
Venue: Education and Information Technologies (2007)

This paper reports on a study in which observation, stimulated recall and semi structured interviews were used to report on children's knowledge and understanding of computer processes. It suggests a model for identifying stages in pupils' understanding of these processes with implications for how best to support and develop that understanding. This was a small scale, exploratory case study involving data collection in two schools. The study differentiated between: simple awareness of computer processes; immediate knowledge of how to use an item or carry out a process; ability to offer a simple explanation for a process; and ability to offer a more sophisticated explanation and to use knowledge to solve problems. It was found that all pupils had an awareness of basic input, output and storage devices and a reasonable level of confidence and competence in using the computer. However, children's knowledge tended to be confined to what they had acquired through experience. Interviews with the same pupils over a period of time showed little development in their conceptualisation of computer processes. Some examples of children's common misconceptions as well as partial and appropriate conceptions are given. An implication for the classroom is that more dialogue between teacher and pupil, or more realistically between teacher and groups of pupils, is needed so that the teacher can ascertain prior knowledge and understanding and present accessible explanations for pupils.

Pull production cycle-time under varying product mixes
Authors: Chakkaphan Athapornmongkon, Jochen Deuse, Chee Yew Wong
Venue: Proceedings of the 38th conference on Winter simulation (2006)

To satisfy customer requirements and simultaneously fully utilize the production machines, there is a need to determine appropriate cycle time. Especially in pull systems with varying product mixes, accurate cycle time is even more crucial. Accurate cycle time also reduces the need for buffers. When the product mix varies, especially in a pull production system with parallel flow, determination of accurate cycle time becomes problematic. Hence this paper studies the relations between cycle times and product mixes in a parallel pull production system using discrete event simulation. Experiments with varying product mixes for parallel production systems are simulated. The simulation results show that optimal cycle time is inversely proportional to product mixes, when the product mix is 50:50 e.g. 120 sec. should be set to each parallel machine to obtain overall cycle time of 60 sec. However, when the mixes are more than 50:50, the proportional rule is not valid.
Simulators for human-oriented training
Authors: William R. Swartout
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Most military simulators are based on vehicles of some sort, such as helicopter simulators, tank simulators, aircraft simulators, and so forth. Without a doubt, such simulators have had a very positive effect on training, reducing cost and at the same time allowing training in situations that would be too dangerous to execute in reality. However, it is also the case that such simulators have largely left the ground-based warfighter in the dust. There is little support for training a soldier for on-the-ground presence patrols or tasks such as tactical questioning. This can be a problem, because a successful mission involves many interpersonal issues, such as leadership when dealing with other team members, cultural awareness when working with locals in a foreign country, and negotiation with other military services or non-governmental organizations. At the Institute for Creative Technologies, we have been constructing a variety of systems that address these needs. These range from systems that have been largely constructed with off-the-shelf technology and are readily deployable to advanced research prototypes that are pushing the bounds of what can be accomplished in simulation. In this talk, I will discuss three of the systems the ICT has developed. The first, SLIM-ES3, is a web-delivered training system that allows a soldier to practice skills such as threat identification, active surveillance, and information gathering. The second, AXL, is a mixed-media environment that helps develop leadership skills. Finally, the third system, SASO-ST, uses virtual humans to help a soldier acquire negotiation skills.
Adapting the interaction in a call centre system
Authors: Federica Cena, Ilaria Torre
Venue: Interacting with Computers (2006)

This paper describes Adaptive Response and Routing System (ARRS), a system which personalizes the management of the entire answering process in a Call Centre infrastructure. The system is characterized by combining two kinds of adaptation: to the caller and to the operator. The aim is to support the user incrementally, improving the global quality of the interaction. In particular, the system combines a first process of automatic and personalized response with a second one of adaptive routing of the call to the operator who best fits the caller's features, according to a user-centered workflow. The results of a preliminary evaluation confirm the validity of the approach.

Discriminant neighborhood embedding for classification
Authors: Wei Zhang, Xiangyang Xue, Hong Lu, Yue-Fei Guo
Venue: Pattern Recognition (2006)

In this paper a novel subspace learning method called discriminant neighborhood embedding (DNE) is proposed for pattern classification. We suppose that multi-class data points in high-dimensional space tend to move due to local intra-class attraction or inter-class repulsion and the optimal embedding from the point of view of classification is discovered consequently. After being embedded into a low-dimensional subspace, data points in the same class form compact submanifod whereas the gaps between submanifolds corresponding to different classes become wider than before. Experiments on the UMIST and MNIST databases demonstrate the effectiveness of our method.

A bee colony optimization algorithm to job shop scheduling
Authors: Chin Soon Chong, Appa Iyer Sivakumar, Malcolm Yoke Hean Low, Kheng Leng Gay
Venue: Proceedings of the 38th conference on Winter simulation (2006)

In the face of globalization and rapidly shrinking product life cycle, manufacturing companies are trying different means to improve productivity through management of machine utilization and product cycle-time. Job shop scheduling is an important task for manufacturing industry in terms of improving machine utilization and reducing cycle-time. However, job shop scheduling is inherently a NP-hard problem with no easy solution. This paper describes a novel approach that uses the honey bees foraging model to solve the job shop scheduling problem. Experimental results comparing the proposed honey bee colony approach with existing approaches such as ant colony and tabu search will be presented.
Reasoning with multiple-source information in a possibilistic logic framework
Authors: Salem Benferhat, Claudio Sossai
Venue: Information Fusion (2006)

This paper addresses the problem of merging uncertain information in the framework of possibilistic logic. It presents several syntactic combination rules to merge possibilistic knowledge bases, provided by different sources, into a new possibilistic knowledge base. These combination rules are first described at the meta-level outside the language of possibilistic logic. Next, an extension of possibilistic logic, where the combination rules are inside the language, is proposed. A proof system in a sequent form is given, sound and complete with respect to the possibilistic logic semantics. Possibilistic fusion modes are illustrated on an example inspired from an application of a localization of a robot in an uncertain environment.
Market reactions to E-business outsourcing announcements: an event study
Authors: Manish Agrawal, Rajiv Kishore, H. Raghav Rao
Venue: Information and Management (2006)

Stock markets have reacted favorably to firms who announced their implementation of E-business projects for commercial exploitation. Those that outsourced E-business projects in order to achieve swift execution also achieved abnormal positive returns. Contrary to expectations, outsourcing E-business projects with high task complexity also led to positive results. We analyzed the process and found that these three factors explained more than 20% of the variance in abnormal returns. The results were obtained from an event study of 96 E-business-related announcements, including those made by firms in the S&P500 index during 1999-2002. This paper contains information that should therefore help firms identify E-business projects for outsourcing.
