AbstractCar crash simulation analysis is an important phase within the vehicle development. It intends to analyse the crashworthiness of the vehicle model and examine the level of passive security. However, this activity is not trivial because of the considerable collaboration within the project, the large amount of analysed and exchanged data and a high exigency. Consequently, a solution to assist, ease and reduce the time of the process is desired.To study the current practices followed in the car crash simulation analysis an empirical study has been conducted. This study has been applied within the simulation analysis team, in the development phase, within an automotive company. This paper describes a qualitative analysis of the industrial context and diagnoses the dysfunctions in the current practices. This paper also highlights the current challenges encountered in the car crash simulation analysis.

AbstractIn automotive industry, the design process is costly and time-consuming. Car safety is a crucial factor in the development of a vehicle, which is why crash simulation is an essential step in the design process. To improve car crash simulation analysis, it is necessary to reduce the time required and support the resolution of encountered design issues. We propose a knowledge management approach to support car crash simulation analysis and ensure the collaboration of different stakeholders. In a knowledge-intensive context, we used an ontology-based approach to formalise and capture knowledge.

Context: Requirements elicitation is a software development phase that should investigate both functional and user experience (UX) requirements. Proto-persona is a technique that encourages the attention on the needs of a group of users. Usually, its elaboration is conducted by software specialists, technical stakeholders. However, non-technical stakeholders usually know more about target users and frequently do not take part in proto-persona elaboration. Objective: This work has the goal of investigating the contribution of non-technical stakeholders in the specification of UX requirements by using the proto-persona technique. For this, we explored the construction of the proto-personas and the use of these to the prototyping of solutions. Method: We carried out an empirical study in two rounds from which we analyzed and compared the contribution that technical and non-technical stakeholders had on the specification of UX requirements. In the first, 8 non-technical and 5 technical stakeholders built proto-personas. Afterwards, 18 pairs of software developers created low fidelity prototypes by using the information of proto-personas.~For the two rounds, we conducted a qualitative analysis exploring which UX requirements were described and used. Results: Our results revealed that both stakeholders have written up details of UX requirements on the artifact, however, throughout different and complementary perspectives. We also could observe that proto-personas produced by both were used on the prototyping activity. Conclusion: Our paper contributed to demonstrate that non-technical stakeholders were able to contribute to the specification of UX requirements and that proto-persona can boost such activity.

In the last few years, Online Social Networks (OSN) have experienced growth in the number of users, becoming an increasingly embedded part of people’s daily lives. Privacy expectations of OSNs are higher as more members start realizing potential privacy problems they face by interacting with these systems. Inspection methods can be an effective alternative for addressing privacy problems because they detect possible defects that could be causing the system to behave in an undesirable way. Therefore, we proposed a set of privacy inspection techniques called PIT-OSN (Privacy Inspection Techniques for Online Social Network). This paper presents the description and evolution of PIT-OSN through the results of a preliminary empirical study. We discuss the quantitative and qualitative results and their impact on improving the techniques. Results indicate that our techniques assist non-expert inspectors uncover privacy problems effectively, and are considered easy to use and useful by the study participants. Finally, the qualitative analysis helped us improve some technique steps that might be unclear.

Purpose This study aims to represent an early attempt to define the notion of continuity and empirically illustrate its explanatory potential and methodological challenges. Design/methodology/approach This study combines historical and qualitative research techniques to conduct a qualitative analysis of continuity in the Jablkowski Brothers Department Store, a Polish centennial company. The paper highlights the potential synergies between historical and qualitative methods when applied to the analysis of long periods of time. Findings The authors find that using a theoretical framework of continuity provides novel ontological and epistemological insights into the nature of long-lived companies. Based on the findings, the authors present continuity in the context of existing theories and argue that it is a unique concept that deserves more scientific attention and rigorous empirical study. Originality/value This study contributes to the existing literature in three ways. First, it provides a brief, interdisciplinary overview of the concept of continuity. Second, it provides an empirical illustration of continuity analysis in a Polish centennial company with extremely discontinuous history. Finally, it positions continuity within the wider context of existing theories and shows how, through continuity, history can contribute to both the practice and theory of management.

Permission-related issues in Android apps have been widely studied in our research community, while most of the previous studies considered these issues from the perspective of app users. In this paper, we take a different angle to revisit the permission-related issues from the perspective of app developers. First, we perform an empirical study on investigating how we can help developers make better decisions on permission uses during app development. With detailed experimental results, we show that many permission-related issues can be identified and fixed during the application development phase. In order to help developers to identify and fix these issues, we develop PerHelper, an IDEplugin to automatically infer candidate permission sets, which help guide developers to set permissions more effectively and accurately. We integrate permission-related bug detection into PerHelper and demonstrate its applicability and flexibility through case studies on a set of open-source Android apps.

The article discusses manifestations of procrastination and Internet addiction in high school students within the context of risks of the modern society and education. The purpose of the study is to analyze interrelations between the phenomena of procrastination and Internet addiction in high school students’ personality. The empirical study involved 120 students of the 9th – 11th grades from the cities of Saratov and Balashovaged 15 to 17. We used the questionnaire called “The Degree of Procrastination Intensity” by M.A. Kiselev (system vector psychology SVP), the technique for determining Internet addiction by S.H. Chen and the test for Internet addiction identification by Kimberly Young. We used the author’s questionnaire for qualitative analysis of the interrelation between procrastination and Internet addiction of the subjects. The established relationships between the phenomena of procrastination and Internet addiction (analysis of correlation relationships, typological analysis).New data have been obtained that reveal the nature of the determination of these phenomena in a sample of high school students interacting in modern conditions of education.

This paper explores the consequences of the socio-historical exclusion of women, and of young people, from public life. It is based upon an empirical study in which depth-interviews were conducted with 96 Britons, male and female, and of a younger and an older generation, concerning their private and public lives. Self-proclaimed ignorance is significantly more likely to be found in the interviews of the women rather than the men, and in those of the younger rather than the older generation. Qualitative analysis reveals that self-proclaimed ignorance is associated with a sense of distance from public affairs. The various manifestations of distance are discussed in terms of exposure to knowledge, the individualistic society's expectations concerning the knowing “I”, the privatized market economy and the effects of modernity itself.
