Purpose Low-cost microcomputers such as the Raspberry Pi are common in library makerspaces. This paper aims to create an OBD-II technology to diagnose a vehicle’s condition. Design/methodology/approach An OBD-II scanner plugged into the OBD-II port or usually called the data link connector (DLC), sends diagnostics to the Raspberry Pi. Findings Compared with other microcontrollers such as Arduino, the Raspberry Pi was chosen because it sustains the application to receive real-time diagnostics, process the diagnostics and send commands to automobiles at the same time, rather than Arduino that must wait for another process finished to run another process. Originality/value This paper also represents the history of mobile technology and OBD-II technology, comparison between Arduino and Raspberry Pi and Node.

Purpose This paper aims to examine a congestion situation of a certain type of restaurant in a theme park (Tokyo Disney Resort) by a simulation based on Little’s law, which is a basic principle in Queueing theory. In the restaurant, a guest (customer) lines up to order, pay and receive dishes. A problem is that even when a guest can easily find vacant tables, it takes a long time to receive dishes. Because guests can see there are vacant tables, there are many tweets of complaints. This situation is a factor to undermine customer satisfaction. Design/methodology/approach This paper proposes dedicated special menu lines only providing special set as one solution that can be realized at a low cost to reduce vacant tables. Here, if the number of special menu lines is fixed, the difference between a queue in regular lines and that in special menu lines will be big. To shorten the difference, the author proposes a technique to regulate by using feedback control (Proportional control or Fuzzy control). Findings The simulation result shows that the number of vacant tables decreases by about 16 per cent compared with the current situation. Originality/value This paper considers a specific restaurant, but the proposed method can be applied to the same type of restaurant in the theme park. If the restaurant in the theme park is crowded, the feedback control of the queue brings new possibilities.

Progressive Cognitive Impairment

Purpose Alzheimer’s is the most commonly occurring neurodegenerative disease and progressive cognitive impairment is its major symptom due to which the patients tend to wander and get lost in unfamiliar places. This is a constant cause of worry for caretakers and a source of distress to the patients themselves. The paper aims to discuss this issue. Design/methodology/approach This paper presents a low-cost, autonomous, embedded systems-based wearable device for real-time location tracking using GPS and the concept of geo-fencing. The system provides real-time updates in the form of a text message sent to the mobile number of a family member or caregiver. Findings An alert is sent whenever the patient moves out of a certain “safe zone” area and sends subsequent updates after every 5 min of such an event. The system supports caregivers of patients with early and moderate Alzheimer’s disease. Social implications Alzheimer’s patients are prone to disorientation, confusion and tend to wander off. Since the device eliminates the need for the patients to operate it and is instead at the discretion of the system itself, the chances of it failing to help are minimized. Hence, with this project, the authors address the need for an autonomous device that can assist caretakers in tracking Alzheimer’s patients. Originality/value The various existing technologies that are in use now for tracking are often high in price, not tailored to Alzheimer’s and are non-autonomous. To overcome this, the authors utilized easily accessible technology into developing this system, which not only be affordable, but also addresses the major flaw in existing systems – which is that they rely on being operated by the patients themselves.

Purpose The purpose of this paper is to evaluate the historical pollution of the Hostivar Reservoir (largest reservoir in Prague) sediment by metals, polyaromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) and identify the trends in pollution of aquatic environment. Design/methodology/approach Core samples, 140 cm long, recording the 45-year history of the reservoir, were separated to 5 cm width subsamples (approximately 1.5 years of sedimentation) and analyzed for metals (Cd, Pb, Cu, Zn, Cr, Ni, Al), PAH and PCB. Following methods were used: US EPA 3051 for metals, US EPA 505 and US EPA 8082 A for PCB, and ISO 18287:2006 for PAH. Findings Most of the contaminants had the highest concentration at the beginning of the existence of the reservoir, suggesting that the contamination results from construction activities. Significant decrease of Pb occurred in the second half of the 1990s. It was caused by termination of the addition of lead as a detonation suppressant to the gasoline. Most concentrations of PAHs, PCBs and metals, except copper do not present eco-toxicological risk. Practical implications The results show the volume of priority pollutants removed from the reservoir by sediment extraction, and point risk to the terrestrial environment due to application of the sediment in the construction of a noise protecting wall. Originality/value The paper presents unique data about historical contamination of the largest reservoir in Prague, the capital of Czech Republic. It shows how the watershed and the construction phase of the dam cause a pollution of the reservoir sediment and possible environmental risk for aquatic biota.

PurposeThe purpose of this paper is to examine the transformations of prosthetic practices in China, as well as the daily experiences and dilemmas arising from the everchanging practices since 1949. On the basis of materials, this paper explores an everyday perspective to review the history of technology.Design/methodology/approachEthnography was collected with the application of participant observations, informal interviews and in-depth interviews during a 13-months study at a rehabilitation center in Chengdu, China. The literature on prosthetic manufacturing was also reviewed for this paper.FindingsChina's prosthetic technology seems to evolve from traditional to modern. However, this progressive narrative – innovation-based timeline (Edgerton, 2006, xi) – has been challenged by daily practices. Due to institutional pressures, prosthetists are in a dilemma of selectively using their knowledge to create one kind of device for all prosthesis users with a certain kind of disability, thereby regulating the physical and social experiences of prosthesis users. Besides, prosthesis users are accustomed to prostheses made with old techniques, and must correct themselves from old experiences to the daily practices recognized by the selected techniques.Originality/valueThis paper provides a cross-cultural case to reexamine Edgerton's criticism of the progressive and orderly innovation-centric technological narrative. More importantly, it reviews the history and practices of China's prosthetics from daily experiences rather than Edgerton's concentration on technology; therefore, it provides an everyday perspective for future research on technological transformations.

The Subject

Purpose – The purpose of this paper is to examine how the boundaries of rhetoric have excluded important theoretical and practical subjects and how these subjects are recuperated and extended since the twentieth century. Its purpose is to foster the awareness on emerging new trends of rhetoric. Design/methodology/approach – The methodology is based on an interpretation of the history of rhetoric and on the construction of a conceptual framework of the rhetoric of judgment, which is introduced in this paper. Findings – On the subject of the extension of rhetoric from public speeches to any kinds of persuasive situations, the paper emphasizes some stimulating relationships between the theory of communication and rhetoric. On the exclusion and recuperation of the subject of rhetorical arguments, it presents the changing relationships between rhetoric and dialectics and emphasizes the role of rhetoric in scientific research. On the introduction of rhetoric of judgment and meanings it creates a conceptual framework based on a re-examination of the concept of judgment and the phenomenological foundations of the interpretative methods of social sciences by Alfred Schutz, relating them to symbolic interactionism and theories of the self. Originality/value – The study on the changing boundaries of rhetoric and the introduction of the rhetoric of judgment offers a new view on the present theoretical and practical development of rhetoric, which opens new subjects of research and new fields of applications.

Purpose – This paper aims to explore the sociological process behind the development of the American Marketing Association (AMA). It shows how the shift from isolated endeavors to an organized movement happened in marketing, how and why marketing pioneers merged to build a professional body and what this body provided to its community and to society at large. Design/methodology/approach – This paper studies the history of the AMA from the perspective of the sociology of science and relies on the marketing literature and other written sources. Findings – The paper shows that the AMA is both the result and the center of a coupling procedure. Isolated pioneers in the marketing field found it useful to communicate with those who were engaged in endeavors similar to their own. The meeting resulted in a dialog, and the dialog had necessitated the establishment of the AMA as a common reference point. The AMA provided the marketing community with a language and an institution that could help them to exist and move forward together. Originality/value – This paper provides an up to date account of the history of the AMA as well as a sociological analysis of its development.

Obligation To Inform

Purpose Corporate foreign bribery can have devastating consequences on communities and states. Over the past decade, there have been several promising developments, both national and international, that might increase the chances of victim states to receive remediation for the harm they suffered from foreign bribery. In particular, awareness has risen that victim states must be considered and new innovative items have been added to the toolbox of prosecutors in the fight against corruption that is assumed to also improve victim states’ standing in these procedures. This study aims to assess whether indeed victim states receive compensation through these novel procedures. Design/methodology/approach This study uses the three case studies of Switzerland, France and England and Wales for a comprehensive empirical and normative analysis of settlement agreements between defendants and prosecution authorities and of court jurisprudence. Findings This study shows that although de jure, it seems warranted to order the payment of remedies to victim states within domestic criminal proceedings, in practice, this rarely happens. A number of legal and practical obstacles account for this situation. This study, therefore, calls for the formulation of international guidelines containing the obligation to inform victim states of ongoing criminal proceedings on corporate foreign bribery, and guidance on how to identify the victim of this crime, as well as the damage caused. Originality/value This is the first contribution to verify whether claims that settlement agreements, recently introduced in England and Wales and France (and similar procedures are available in Switzerland), are beneficial for victim states in their quest to receive compensation. As this study shows that this is – not yet – the case in practice, this study proposes solutions that could lead the way for remediation of the harm caused by corporate corruption – and thereby, ultimately, to a more just outcome.

Case Based Learning

PurposeThe purpose of this paper is to analyze the influence of two active methodologies on digital competences development using mobile devices. The first methodology is project-oriented learning (POL); the second one is case-based learning (CBL). The analyzed digital competences belong to the communication and collaboration area of framework DIGCOMP.Design/methodology/approachThis article shows the results of the quantitative stage with a design pre-experimental pre-test–post-test. A questionnaire was designed and applied to an intentional sample from two different courses. In total, 178 students completed the questionnaire in the pre-test, and after five months, 38 students completed the questionnaire in the post-test.FindingsThe results show that students to whom POL was applied increase by 7% competence of interaction with mobile technology. The results also show that the students to whom CBL was applied to increase all four competencies (interaction +8%, share +6%, collaboration +5%, netiquette +4%).Research limitations/implicationsSelf-perception for the evaluation of digital competence and the short study time are limitations to generalize the results, so a longitudinal study is necessary and complemented with qualitative analysis, to present a better validation of the contribution of active methodologies to the development of digital competences.Originality/valueThe rapid advance of technology and the results of various investigations make evident the need of digital competences development. The most common process is digital literacy through techno-functional training. However, these research results confirm that it is possible to promote these digital competences from a practical view and implicitly in active methodologies educational practices.
