Using mobile RE tools to give end-users their own voice
Researchers highlight end-user involvement in system design as an important concept for developing useful and usable solutions. However, end-user involvement in software engineering is still an open-ended topic. Novel paradigms such as service-oriented computing strengthen the need for more active end-user involvement in order to provide systems that are tailored to individual end-user needs. Our work is based on the fact that the majority of end-users are familiar with mobile devices and use an increasing number of mobile applications. A mobile tool enabling end-user led requirements elicitation could be just one of many applications installed on end-users' mobile devices. In this paper, we present a framework of end-user involvement in requirements elicitation which motivates our research. The main contribution of our research is a tool-supported requirements elicitation approach allowing end-users to document needs in situ. Furthermore, we present first evaluation results to highlight the feasibility of on-site end-user led requirements elicitation
Systematic evaluation of perceived spatial quality
The evaluation of perceived spatial quality calls for a method that is sensitive to changes in the constituent dimensions of that quality. In order to devise a method accounting for these changes, several processes have to be performed. This paper shows the development of scales by elicitation and structuring of verbal data, followed by validation of the resulting attribute scales
To get or to be? Use and acquisition of get- versus be- passives: evidence from children and adults
The use and acquisition of the get-passive has so far yielded a variety of accounts and suggestions. This paper presents new experimental evidence concerning the use and the acquisition of the get-passive by children, as well as adult judgments of get- and be-passives. Within a prototype approach to the passive, experiments investigated when 2â4-year-old British children produce get- as opposed to be-passives. The role of direct affectedness of the patient on
get-passive production was investigated further in a follow-up experiment. In addition to the child data, ratings of get- and be-passives were obtained from British English adult speakers to investigate the acceptability of these passives and their relationship to developmental data. The
first experiment showed that the chosen prototype approach clearly predicts childrenâs acquisition of be-passives with get-passives being more peripheral members of the category
âpassiveâ than be-passives. The second study shows that even if the child herself is the affected patient in the play action, get-passives are only rarely produced. In contrast to American children, direct affectedness did not induce British children to produce a significant amount of getpassives. Last, adult ratings confirm that British English speakers rate be-passives consistently as better examples of passive sentences than get-passives. The evidence suggests that getpassives are more peripheral for British than for American children and adults. Implications for the possible role of parental input and the validity of existing accounts of the get-passive are discussed

Using plenary focus groups in information systems research: More than a collection of interviews
Standard data collection techniques in qualitative research have included surveys, interviews and observations. The Focus group technique is a more recent addition to the empirical researcher's repertoire and is highly appropriate to Information Systems research in particular circumstances. This paper introduces a focus group approach to the study of information systems using a case study scenario and employing a structuring technique borrowed from Soft Systems Methodology designed to shape the discussion and organize group attention on specific aspects of the descriptive process. The paper describes the conduct of focus groups with respect to individual incidents and defines a particular type of Focus Group which involves all persons attendant at an event, thereby removing problems of sampling and representativeness. The unique properties and advantages of this type of focus group in respect to IS research emerged from the case study and an example of the use of story elicitation technique is described. The case study scenario is a regional fire service and any fire or rescue related incident is unique, dynamic, live and real-time, in addition it requires the combined skills and actions of a group of individuals, none of whom may have a full overview of the situation until after the event. These factors are present in other events such as any emergency procedure, artistic or sporting performance, construction and demolition events. Recording of such events presents genuine problems for information systems and the elicitation technique helped the group members to think in different ways about the impact of their incident recording systems. As the technique has broader use across research disciplines, an attempt is made to identify the attributes and properties of these 'Plenary Focus Groups' in information systems research scenario that might lend themselves to focus group research as a useful and successful technique
