Robust Dynamic Comfort Modeling for Motorcycle Riding

2014

Comfort modeling is considered a prerequisite in motorcycle design, primarily to address safety concerns and to position the product on the market. However, a comprehensive methodology for comfort modeling during the earliest development phases of a motorcycle model is still missing. Anthropometrical variation is the main noise factor to consider in comfort modeling in relation to the unavoidable variability of body segments. However, comfort is a subjective concept influencing riders' choice of motorcycle model. This work is a generalization of the robust ergonomic design methodology aimed at designing products whose ergonomic performance is insensitive to anthropometrical variation. This …

Empirical Study on Cyber Range Capabilities, Interactions and Learning Features

2021

Emerging technologies and the globalization require constant investment in people and their performance in actual and virtual environments. New technologies such as autonomous systems, machine learning and artificial intelligence (AI) radically re-contextualize the human dimension of the organization. Technological developments are changing the ways people experience the physical and the virtual environments. Strategic changes have revealed new critical vulnerabilities such as social media-based disinformation campaigning with impact on the human aspects at state, societal, organizational and individual levels. Scenarios of gathering information, committing fraud or getting access to critic…

Association of extent of cannabis use and psychotic like intoxication experiences in a multi-national sample of first episode psychosis patients and …

2021

AbstractBackgroundFirst episode psychosis (FEP) patients who use cannabis experience more frequent psychotic and euphoric intoxication experiences compared to controls. It is not clear whether this is consequent to patients being more vulnerable to the effects of cannabis use or to their heavier pattern of use. We aimed to determine whether extent of use predicted psychotic-like and euphoric intoxication experiences in patients and controls and whether this differs between groups.MethodsWe analysed data on patients who had ever used cannabis (n = 655) and controls who had ever used cannabis (n = 654) across 15 sites from six countries in the EU-GEI study (2010–2015). We used multiple regres…

The Safety Culture Enactment Questionnaire (SCEQ): Theoretical model and empirical validation

2015

This paper presents the Safety Culture Enactment Questionnaire (SCEQ), designed to assess the degree to which safety is an enacted value in the day-to-day running of nuclear power plants (NPPs). The SCEQ is based on a theoretical safety culture model that is manifested in three fundamental components of the functioning and operation of any organization: strategic decisions, human resources practices, and daily activities and behaviors. The extent to which the importance of safety is enacted in each of these three components provides information about the pervasiveness of the safety culture in the NPP. To validate the SCEQ and the model on which it is based, two separate studies were carried…

Design of a safety training package for migrant workers in the construction industry

2021

Abstract The construction sector is known as a high-risk sector with many safety challenges. It is also characterised by a large number of migrant workers and these workers report higher accident rates than native workers. This paper presents the design of the CSTP (Construction Safety Training Programme). The CSTP is a theory-based training program aimed at improving safety behaviours in construction sites acknowledging the particular challenges migrant workers face. Based on second and third generational models of training, we developed a training program that addresses the challenges faced by migrant workers in the construction industry, namely language and cultural barriers, times press…

How do individuals emotionally cope with the imminent real-world salience of mortality? DeWall and Baumeister as well as Kashdan and colleagues previously provided support that an increased use of positive emotion words serves as a way to protect and defend against mortality salience of one’s own contemplated death. Although these studies provide important insights into the psychological dynamics of mortality salience, it remains an open question how individuals cope with the immense threat of mortality prior to their imminent actual death. In the present research, we therefore analyzed positivity in the final words spoken immediately before execution by 407 death row inmates in Texas. By u…

User Evaluation of the Smartphone Screen Reader VoiceOver with Visually Disabled Participants

2018

Touchscreen assistive technology is designed to support speech interaction between visually disabled people and mobile devices, allowing hand gestures to interact with a touch user interface. In a global perspective, the World Health Organisation estimates that around 285 million people are visually disabled with 2/3 of them over 50 years old. This paper presents the user evaluation of VoiceOver, a built-in screen reader in Apple Inc. products, with a detailed analysis of the gesture interaction, familiarity and training by visually disabled users and the system response. Six participants with prescribed visual disability took part in the tests in a usability laboratory under controlled con…

¿Son realmente tan buenos los nativos digitales?: relación entre las habilidades digitales y la lectura digital

2015

Digital reading literacy consists on the comprehension, use, reflection and enjoyment of written texts with the aim to fulfill our goals, to develop our knowledge and potential, and to participate in our society. Currently it is considered that “digital natives”, i.e. those students that have been raised surrounded by information technologies, poses the basic digital skills (such as using the mouse, the browser, …) required to develop digital reading skills. The present study tested this assumption, by means of a study in which students of 5th level of primary education and 3rd level of secondary education performed a series of digital reading tasks. In addition, students completed several …

Reliability and validity of the Home Care STAT (Safety Task Assessment Tool).

2013

Abstract Home care workers are a priority population for ergonomic assessment and intervention, but research on caregivers' exposures to hazards is limited. The current project evaluated the reliability and validity of an ergonomic self-assessment tool called Home Care STAT (Safety Task Assessment Tool). Participants (N = 23) completed a background survey followed by 10–14 days of self-monitoring with the STAT. Results showed that the most frequent task was house cleaning, and that participants regularly performed dangerous manual client moving and transferring tasks. Researcher in-home observations of 14 workers (duration ≤2 h) demonstrated that workers' self-assessments were moderately re…

Driver training interests of a Spanish sample of young drivers and its relationship with their self-assessment skills concerning risky driving behavi…

2013

Abstract Poor driving self-assessment skills (e.g., over-confidence) have been pointed out as an important explanatory factor behind young drivers’ accident involvement. This paper explores (1) what young drivers miss in their training as drivers in order to analyze whether an assessment of one's own driving skills plays an important role in their desire to improve as drivers, and (2) how these training interests are related to an estimate of their self-assessment skills concerning risky driving behavior. For this purpose, a study was conducted using a survey with a blocked sampling design of novice drivers. The survey solicited respondents’ self-report about (1) the contents of training co…
