Behavioural issues in environmental modelling – The missing perspective

The paper aims to demonstrate the importance of behavioural issues in environmental modelling. These issues can relate both to the modeler and to the modelling process including the social interaction in the modelling team. The origins of behavioural effects can be in the cognitive and motivational biases or in the social systems created as well as in the visual and verbal communication strategies used. The possible occurrence of these phenomena in the context of environmental modelling is discussed and suggestions for research topics are provided.     

What’s missing in geographical parsing?

Geographical data can be obtained by converting place names from free-format text into geographical coordinates. The ability to geo-locate events in textual reports represents a valuable source of information in many real-world applications such as emergency responses, real-time social media geographical event analysis, understanding location instructions in auto-response systems and more. However, geoparsing is still widely regarded as a challenge because of domain language diversity, place name ambiguity, metonymic language and limited leveraging of context as we show in our analysis. Results to date, whilst promising, are on laboratory data and unlike in wider NLP are often not cross-compared. In this study, we evaluate and analyse the performance of a number of leading geoparsers on a number of corpora and highlight the challenges in detail. We also publish an automatically geotagged Wikipedia corpus to alleviate the dearth of (open source) corpora in this domain.     

The experience of enchantment in human–computer interaction

Improving user experience is becoming something of a rallying call in human–computer interaction but experience is not a unitary thing. There are varieties of experiences, good and bad, and we need to characterise these varieties if we are to improve user experience. In this paper we argue that enchantment is a useful concept to facilitate closer relationships between people and technology. But enchantment is a complex concept in need of some clarification. So we explore how enchantment has been used in the discussions of technology and examine experiences of film and cell phones to see how enchantment with technology is possible. Based on these cases, we identify the sensibilities that help designers design for enchantment, including the specific sensuousness of a thing, senses of play, paradox and openness, and the potential for transformation. We use these to analyse digital jewellery in order to suggest how it can be made more enchanting. We conclude by relating enchantment to varieties of experience.An earlier version of this paper was presented at Chi’2004 Fringe.     

The influence of empathy in human–robot relations

The idea of robotic companions capable of establishing meaningful relationships with humans remains far from being accomplished. To achieve this, robots must interact with people in natural ways, employing social mechanisms that people use while interacting with each other. One such mechanism is empathy, often seen as the basis of social cooperation and prosocial behaviour. We argue that artificial companions capable of behaving in an empathic manner, which involves the capacity to recognise another's affect and respond appropriately, are more successful at establishing and maintaining a positive relationship with users. This paper presents a study where an autonomous robot with empathic capabilities acts as a social companion to two players in a chess game. The robot reacts to the moves played on the chessboard by displaying several facial expressions and verbal utterances, showing empathic behaviours towards one player and behaving neutrally towards the other. Quantitative and qualitative results of 31 participants indicate that users towards whom the robot behaved empathically perceived the robot as friendlier, which supports our hypothesis that empathy plays a key role in human–robot interaction.     

Evaluating data-centric process approaches: Does the human factor factor in?

The Business Process Management field addresses design, improvement, management, support, and execution of business processes. In doing so, we argue that it focuses more on developing modeling notations and process design approaches than on the needs and preferences of the individual who is modeling (i.e., the user). New data-centric process modeling approaches are taken as a relevant and timely stream of process design approaches to test our argument. First, we provide a review of existing data-centric process approaches, culminating in a theoretical classification framework. Next, we empirically evaluate three specific approaches with regard to the claims they make. We had participants representative of actual users try out these approaches on realistic scenarios via a series of workshops. Participants assessed to what extent quality claims from the literature could be recognized within the workshop sessions. The results of this evaluation substantiate a number of claims behind the approaches, but also identify opportunities to further improve them. Most prominently, we found that the usability aspects of all considered approaches are a source of concern. This leads us to the insight that usability aspects of process design approaches are crucial and, in the perception of groups representative of actual users, leave much to be desired. In that sense, our research can be seen as a wake-up call for process modeling notation designers to consider the usability side—and as such, the interest of the human modeler—more than is currently the case.     

Basic-needs to globalization: Are ICTs the missing link?

The discourse on globalization intersects with assumptions about how new information and communication technologies can generate economic growth in less developed countries. This paper is a critical review of some of these assumptions. It argues that the current processes of globalization cannot on their own foster economic development because globalization is inherently dialectical. It can create wealth for some countries while at the same time, it can impoverish others thus further accentuating the marginalization of many countries. The paper concludes by suggesting ways in which less developed countries can stay “connected” with the global economy while at the same time pursuing development strategies that will meet the basic needs of the majority of their populations.     

Proteomics in rheumatology: The beginning of a fairy tale?

One of the major challenges in proteome research is to translate its applications to the setting of human diseases. Proteomics in rheumatology is an area with marked potential including applications ranging from diagnostics, over therapeutic monitoring to discovery of new potential therapeutic targets. Biomarkers will be essential to discriminate between clinical similar rheumatic diseases, to monitor disease-states or to install the best appropriate therapy. Especially in the field of rheumatology, analysis of specific genes and/or their expression products by pharmacogenetics/-genomics or pharmacoproteomics could be necessary to enable an effective, patient-tailored therapy. In rheumatology, direct examination of proteins may be of utmost importance, as it is already known that PTMs, such as citrullination of proteins or peptides, may be involved in certain rheumatic diseases. The discovery and validation of antibodies directed against citrullinated proteins/peptides in rheumatic diseases using proteome analysis approaches has been described. Gel-free methods, SELDI-approaches and classic 2-DE approaches have been deployed on body fluids as well as on target tissues in different rheumatic diseases. Proteomics in rheumatology is on the rise and pilot studies have indicated that the application of proteomics-based technologies in rheumatic diseases appears to be an exciting example of translational research.     

Route instructions in map-based human–human and human–computer dialogue: A comparative analysis

When conveying information about spatial situations and goals, speakers adapt flexibly to their addressee in order to reach the communicative goal efficiently and effortlessly. Our aim is to equip a dialogue system with the abilities required for such a natural, adaptive dialogue. In this paper we investigate the strategies people use to convey route information in relation to a map by presenting two parallel studies involving human–human and human–computer interaction. We compare the instructions given to a human interaction partner with those given to a dialogue system which reacts by basic verbal responses and dynamic visualization of the route in the map. The language produced by human route givers is analyzed with respect to a range of communicative as well as cognitively crucial features, particularly perspective choice and references to locations across levels of granularity. Results reveal that speakers produce systematically different instructions with respect to these features, depending on the nature of the interaction partner, human or dialogue system. Our further analysis of clarification and reference resolution strategies produced by human route followers provides insights into dialogue strategies that future systems should be equipped with.     

Information Security management: A human challenge?

This paper considers to what extent the management of Information Security is a human challenge. It suggests that the human challenge lies in accepting that individuals in the organisation have not only an identity conferred by their role but also a personal and social identity that they bring with them to work. The challenge that faces organisations is to manage this while trying to achieve the optimum configuration of resources in order to meet business objectives. The paper considers the challenges for Information Security from an organisational perspective and develops an argument that builds on research from the fields of management and organisational behaviour. It concludes that the human challenge of Information Security management has largely been neglected and suggests that to address the issue we need to look at the skills needed to change organisational culture, the identity of the Information Security Manager and effective communication between Information Security Managers, end users and Senior Managers.     

The threats of social networking: Old wine in new bottles?

Despite the many potential benefits to its users, social networking appears to provide a rich setting for criminal activities and other misdeeds. In this paper we consider whether the risks of social networking are unique and novel to this context. Having considered the nature and range of applications to which social networks may be applied, we conclude that there are no exploits or fundamental threats inherent to the social networking setting. Rather, the risks and associated threats treat this communicative and social context as an enabler for existing, long established and well-recognised exploits and activities.     

Proteomics in Drug Development: The Dawn of a New Era?

Mass spectrometry offers the potential of acquiring high resolution data depicting the functional status of a group of healthy or diseased individuals, according to different conditions. As most of the drugs are currently targeting proteins, proteomics has a dual value, both in the discovery of new molecules as therapeutic targets, but also as a methodology to perform high throughput drug profiling. As there is an evident need for drugs to be improved in terms of efficacy, a mechanistic insight for downstream effectors can be valuable in order to predict side effects and resistance mechanisms. Recently developed assays, like thermal proteome profiling enables comprehensive drug target profiling and is, therefore, of high value in drug discovery. In this review, a systematic literature search is conducted and the most prominent proteomics studies as implicated in assisting drug discovery and development is presented. Focus is placed on investigations that are closer to implementation, therefore particular emphasis is given in studies conducted in human diseased population and further verified in vitro or in vivo.     

The Impact of Technology on Creativity in Design: An Enhancement?

Technology may be considered as an interface between individuals and the products they create, but we have to determine whether the use of new systems effectively enhance individuals' creative activities. In this paper, we present a new angle of reflection that we illustrate in the field of creative design, since it is a constant challenge for designers to introduce creativity in the projects they work on. The approach we propose is centred on designers' cognitive processes. We argue that both the development of new CAD (computer‐aided design) systems and their assessment should be conducted on the basis of a deep understanding of designers' cognitive processes. In accordance with this view, we present three empirical studies that were conducted in order to analyse the impact of new design support systems on designers' cognitive processes. Therefore, the results we present contribute to further our knowledge of whether new CAD technologies effectively facilitate designers' activities and enhance their creativity.

Denotation and connotation in the human – computer interface: The ‘Save as …’ command

This paper presents a semiotic technique as a means of exploring meaning and understanding in interface design and use. This is examined through a study of the interaction between the ‘file’ metaphor and ‘save as’ command metaphor. The behaviour of these (from a functional or computational basis) do not exactly match, or map onto, the meaning of the metaphor. We examine both the denotation of a term to the user, i.e. its literal meaning to that person, and the term's connotations, i.e. any other meanings associated with the term. We suggest that the technique applied is useful in predicting future problems with understanding the use of metaphor at the interface and with designing appropriate signification for human-computer interaction. Variation in connotation was expected but a more fundamental difference in denotation was also uncovered. Moreover, the results clearly demonstrate that consistency in the denotation of a term is critical in achieving a good user understanding of the command.     

Ageing: The Common Denominator?

This paper undertakes to explore the gerontological and social science literature for the purpose of highlighting that while ageing is a common phenomenon across all world societies it nevertheless remains a unique personal experience. Drawing upon the metaphorical construct of the life journey, the authors use the cultural context of ageing to illustrate how the life-path for each individual, whether long or short, is necessarily unpredictable and involves a dynamic interaction between history and biography within a particular society and cultural framework. The authors challenge prospective readers to use their sociological imagination as proffered by the renowned sociologist C.W. Mills in the interest of moving beyond the biological dimension in order to see more clearly that ??ageing into old age?? is in essence a unique personal life story. The life story of each individual is seen to represent a compilation of ongoing levels of compliance and /or tension between the individual??s subjective world and external forces the consequence of the individual being a thinking, willing and feeling person, an existential entity with potential for meaning making, self organization and adaptive responses to changing life circumstances. Notwithstanding the diverse cultural, racial and ethnic differences between people worldwide the ageing experience is shown to be a phenomenon displaying cross-cultural variability warranting further ongoing anthropological research. An examination of the many pathways to ageing utilizing a series of interactive factors helps to explain the existence of advantages and disadvantages leading to variations in availability and access to ??life chances?? resulting in many people experiencing unacceptable levels of ill-health, poverty, racism, ageism, inequality and widespread levels of social injustice and abuse of human rights.     

Clinical application of antibody microarray in chronic kidney disease: How far to go?

Chronic kidney disease (CKD) that affects about 10% of the adult population has been shown as a worldwide public health problem in recent years. Both basic and clinical investigations have identified complex disease-associated protein networks involved in the pathophysiologic processes of CKD. The traditional single-assay approach and proteomic analysis of those related proteins have given birth to a steadily increasing panel of molecules that may have the potential to serve as biomarkers for CKD. However, both approaches suffered from some shortcomings from a technological point of view. Antibody microarray (AbM) is characterized by high sensitivity, specificity, and quantitative ability for a particular set of known proteins. However, its application in CKD has been very limited so far. The objective of this review, therefore, is to address the potential applications of AbM in studying of CKD. We will briefly discuss the proteins involved in the development of CKD, future directions in which AbM approaches would probably display its potential and also some key issues that need to be considered in application of this novel technique.     

The world and business computing in 2051: from LEO to RUR?

It is now just over 50 years since the deployment of LEO-the first business computer and application - in 1951. The paper attempts to look 50 years beyond the birth of LEO in order to discern the nature and effects of business computing in 2051.Scenarios are offered of some possible business applications fifty years hence. These include the business information systems in space and the nature of manufacturing.The scenarios serve as a basis for addressing a number of issues. These include the availability of technology to support the scenarios presented, the nature of organizations shaped by future information systems, the nature of employment in the new organizational structure, consumer-vendor relations in the new economy, the effects of the new information technology on the nature of national governments, and the effect of information technologies on the structure of the global economy.
