AbstractSome experiments in chemistry occur too fast to make out the central phenomena. Using common digital cameras or mobile phones with high-speed options, one can slow down the process and make the vital observations visible and capable for the students. This article introduces the research project SloMoChem and will show the benefits of using this digital technology to understand the combustion concept in a much better way.

Access Services

A significant difference exists between wayfinding support services available in outdoor and indoor locations. Users in outdoor locations can access services like Google Maps via a mobile phone and in-car GPS, which allows them to examine unknown locations before arrival as well as receive assistance en-route. In contrast, there is relatively little digital wayfinding support for users in indoor locations, where users are limited to using in-building signage or asking for directions. However, advances in pervasive digital technology allow new possibilities and make this topic increasingly subject to research study. This paper describes three separate formative studies involving 24 participants using personal mobile phones, a situated display deployment and a Person Locator Kiosk. The authors present their findings by gaining feedback and insights from users to develop useful and usable wayfinding support for visitors in an in-building environment.

Mobile Phone Communication

Purpose – The purpose of this paper is to critically analyze the discourses on migrant acculturation and migrants’ mobile phone communication, in order to examine the inclusiveness of communication-acculturation research in the recent years. Design/methodology/approach – The paper draws on from 102 qualitative interviews (48 Malayali, 26 Bangla, 17 Tamil and 11 Telugu) for a larger research project that investigated the role of mobile phones in migrant acculturation in Singapore. Respondents were selected using a combination of purposive and snowball sampling methods. The respondents had been in Singapore for varying amount of time: from one month to 19 years. Findings – The analysis of the discourses on migrant acculturation and mobile phone communication revealed that labor migrants were excluded on the basis of their temporary status and apprehensions on work productivity. The mobile usage prohibitions that existed in work sites were hinged on similar discourses that stereotyped the labor migrants. The emancipatory metaphor that has been at the center of research on migrants’ mobile phone usage and acculturation needs to be replaced with a critical discourse perspective. Research limitations/implications – The data were originally collected for a research project that approached the phenomena of acculturation and mobile phone appropriation from a positivist perspective, whereas this paper analyzed the data to critically examine the discourses that supported the premise of the project itself. Due to this, the findings presented in this paper have limited scope for generalization. Originality/value – The paper critiques the research trends in migrant acculturation and mobile phone communication and suggests a possible alternative that goes beyond the “transcendental teleology” that underpins discourse and practice.

International Research Project

In the context of an international research project on older people’s relations with and through mobile telephony, Italian participants spontaneously provided narrations on mobile phones that appeared to be structured around strong stereotypes. Respondents show a twofold representation of mobile phones either as a simple communication tool or as a ‘hi-tech’ device, which generates multifaceted stereotypes. More specifically, when the mobile phone is considered as a simple communication tool, age-based stereotypes address younger people’s bad manners, while gendered stereotypes depict women as ‘chatterboxes’ or ‘social groomers’. On the other hand, when the mobile phone is considered a ‘hi-tech’ device, age-based stereotypes underline younger people’s advanced user skills, while gendered stereotypes focus on women’s lack of competencies. Based on that, we provide a conceptual framework for analysing such stereotyped – and apparently conflicting – representations. Interestingly, while some issues also emerged in other countries, the masculine assumption that women are less-skilled mobile phone users appears as a peculiarity of Italian respondents.

One of the main obstacles for survey researchers—especially those conducting surveys in difficult contexts such as postconflict areas—is accessing respondents. In order to address this problem, this article draws on an ongoing research project to reflect on the utility of mobile phones to connect with hard-to-access populations in conflict affected, low-income countries. It considers the strengths and weaknesses of a number of different mobile phone survey modes. The article goes a step further and discusses how (potential) survey respondents can be included in the survey design process thereby increasing the relevance of the research to them and hopefully encouraging them to participate. We conclude by considering the issue of “good enough” methodologies, or the need to balance methodological rigor with an understanding of the exigencies of suboptimal research contexts.

Abstract The purpose of this article is to provide clinical supervisors with information pertaining to state-of-the-art clinic observation technology. We use a novel video-capture technology, the Landro Play Analyzer, to supervise clinical sessions as well as to train students to improve their clinical skills. We can observe four clinical sessions simultaneously from a central observation center. In addition, speech samples can be analyzed in real-time; saved on a CD, DVD, or flash/jump drive; viewed in slow motion; paused; and analyzed with Microsoft Excel. Procedures for applying the technology for clinical training and supervision will be discussed.

In the present study we link self-report-data on personality to behavior recorded on the mobile phone. This new approach from Psychoinformatics collects data from humans in everyday life. It demonstrates the fruitful collaboration between psychology and computer science, combining Big Data with psychological variables. Given the large number of variables, which can be tracked on a smartphone, the present study focuses on the traditional features of mobile phones – namely incoming and outgoing calls and SMS. We observed N = 49 participants with respect to the telephone/SMS usage via our custom developed mobile phone app for 5 weeks. Extraversion was positively associated with nearly all related telephone call variables. In particular, Extraverts directly reach out to their social network via voice calls.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.

Advances in technology have dramatically influenced and changed the world of transportation in countless way. While many improvements have been realized with the help of technology in this area, negative consequences, like distracted driving, continue to be formidable challenges to the public’s safety and health. Studies have demonstrated that mobile phones, built-in navigation systems, and other in-vehicle–related entertainment/information technology (infotainment) have contributed to distracted driving, leading to increased morbidity and mortality, especially among the youth. Today, the ubiquitous use of mobile phones while driving has led to major increases of distracted driving, with some attribution to injury and fatal crashes, particularly among young drivers.

The measurement speed and measurement accuracy of a displacement measuring interferometer are key parameters. To verify these parameters, a fast and high-accuracy motion is required. However, the displacement induced by a mechanical actuator generates disadvantageous features, such as slow motion, hysteresis, distortion, and vibration. This paper proposes a new method for a nonmechanical high-speed motion using an electro-optic modulator (EOM). The method is based on the principle that all displacement measuring interferometers measure the phase change to calculate the displacement. This means that the EOM can be used to accurately generate phase change rather than a mechanical actuator. The proposed method is then validated by placing the EOM into an arm of a frequency modulation interferometer. By using two lock-in amplifiers, the phase change in an EOM and, hence, the corresponding virtual displacement could be measured by the interferometer. The measurement showed that the system could achieve a displacement at 20 kHz, a speed of 6.08 mm/s, and a displacement noise level < 100 pm//√Hz above 2 kHz. The proposed virtual displacement can be applied to determine both the measurement speed and accuracy of displacement measuring interferometers, such as homodyne interferometers, heterodyne interferometers, and frequency modulated interferometers.
