The self-reported causes of sleepiness in shift-working tram and truck drivers
2021
Identifying the causes of sleepiness in various safety-critical work environments is neces-sary for implementing more efficient fatigue management strategies. In transportation, little is known about drivers' own perceptions of these causes. Therefore, we instructed shift-working tram (n = 23) and long-haul truck drivers (n = 52) to report at the end of their shifts what made them sleepy if they felt so. These self-reports, measured on-duty sleepiness, and sleep amounts were recorded on every shift over a period of 2-3 weeks per driver. The causes of sleepiness were queried with smartphone applications and sleep logs. Sleepiness was measured with the Karolinska Sleepiness Scale (KSS) and sl…
Typology of human aggression and its biological control
2008
Human aggression is considered a global public health problem with a tremendous impact on the victims. Scientists studying this behaviour can contribute to reducing this worldwide problem by identifying its causes and designing preventive interventions and treatment. Those working on its biological bases need to establish which types of human aggression may be candidates for a biological intervention, which makes it necessary to develop a typology of this behaviour. Considering the primary goal that guides the perpetrator to behave aggressively, a distinction is made between impulsive and premeditated types. However, to control aggression, the distinction should be made between individuals …
Differences in treatment adherence, program completion, and recidivism among batterer subtypes
2017
Abstract The present study aimed to cross-validate Holtzworth-Munroe and Stuart's typology in a Spanish sample of court-referred intimate partner violence batterers. The study also analyzed the typology's capability to predict treatment attendance, completion, and IPV recidivism two years after the treatment. The sample consisted of 210 batterers court referred to a batterer intervention program. Using cluster analysis, three batterer subtypes were identified in accordance with the original typology: family-only batterers, borderline/dysphoric, and generally violent-antisocial. The typology predicted program attendance, completion, and recidivism. Batterers from the generally violent-antiso…
Organization of the social sphere and typology of the residential setting: How the adoption of the mobile phone affects sociability in rural and urba…
2012
Abstract The purpose of this study is to explore the role that the possession of the mobile phone plays in the organization of the relational sphere at a social level, in different geographical settings. The research questions were: is the possession of a mobile phone more connected to urban or to rural life, and does the possession of a mobile phone influence differently the organization of the social sphere in rural and urban settings? Data on the possession of mobile phones, the frequency of forms of communicative sociability, and various socio-demographic variables were collected by means of a phone survey in 2009. The sample is representative of the population in the five most populous…
Discrepancy between individual and organizational values : occupational burnout and work engagement among white-collar workers
2013
Abstract This pilot study aimed to investigate the level of discrepancy between individual and organizational values, and assessed its impact on white-collar workers' job burnout and work engagement. The study examined the hypothesis that the better the fit between individual and organizational values, the higher the work engagement and the lower the risk of professional burnout. The modified Schwartz's typology of values, focusing on work related issues, was used as a framework for the study. Also, organizational level analysis was incorporated into the study questionnaire in order to capture the potential mismatch effect between the person and his or her work environment. A total of 480 w…
A DGS gesture dictionary for modelling on mobile devices
2017
ABSTRACTInteractive or Dynamic Geometry System (DGS) is a tool that help to teach and learn geometry using a computer-based interactive environment. Traditionally, the interaction with DGS is based on keyboard and mouse events where the functionalities are accessed using a menu of icons. Nevertheless, recent findings suggest that such a traditional model of interaction has a steep learning curve and is inadequate to develop DGS for devices with multi-touch screens. Thus, we propose a new interaction model for DGS based on a gesture dictionary which enables the construction and manipulation of geometric objects without the need of accessing a menu of icons. The dictionary is divided into thr…
Operationalization of un-captured GDP - Innovation stream under new global mega-trends
2016
With the understanding that current ICT-driven global development depends on a trend shifting from traditional co-evolution of computer-initiated ICT, captured GDP, and economic functionality to new co-evolution of the Internet, un-captured GDP, and supra-functionality beyond economic value, the following hypothetical view was postulated: The disparity between the world's ICT leader countries with respect to happiness/welfare amidst great stagnation (Finland) or conspicuous economic growth (Singapore) can be attributed to the difference of the state in the above shifting trends. The foregoing hypothetical view was demonstrated on the basis of an empirical analysis measuring dependency on un…
A new paradox of the digital economy - Structural sources of the limitation of GDP statistics
2018
The Internet has dramatically changed the way we conduct business and our daily lives by provided us with unprecedented services and conveniences. However, contrary to such accomplishments, productivity in industrialized countries is now experiences an apparent decline. This has raised the question of a possible productivity paradox in the digital economy. The limitation of GDP statistics in measuring the advancement of the digital economy has thus become an important subject. This paper analyzed the structural sources of this problem. Utilizing the results of empirical analyses of national, industrial, and individual behavior in the digital economy, solutions to these critical issues were …
Perceived safety and attributed value as predictors of the intention to use autonomous vehicles: A national study with Spanish drivers
2019
Abstract Sooner than later, the growing development of Autonomous Vehicles (AVs) will represent not only an imminent transformation of transportation dynamics, but also further advantages for their users, including many improvements in road crash prevention, efficiency and sustainability. However, different concerns and constraints may affect the intention of adopting this technology among its potential customers, especially for what concerns those constraints related to safety, viability and stability. The objective of this study was to examine the influence of perceived safety and value attributed to the AV in the drivers’ intention to use it, considering the drivers’ demographic factors,…
Explaining Extreme Mobile Experiences
2013
Extreme service or product experiences have a major influence on perceptions and behavior. Therefore, numerous studies have collected such single positive and negative experiences to understand which factors affect (dis)satisfaction, value, and quality. However, most of these studies lack the process approach needed for understanding why and how these experiences take place and proceed, whereas the context of mobile applications has also remained highly unexplored. This study aims to fill the gap by presenting the mobile experience process model with empirical evidence of extreme experiences from 606 actual mobile application users. With the help of the model and the detailed descriptions o…
