Are long-haul truck drivers unusually alert? A comparison with long-haul airline pilots.
2020
Abstract Background Recent studies suggest heavy vehicle drivers self-estimate their sleepiness unexpectedly low during night duties. The present study compared sleepiness ratings of long-haul truck drivers with those of long-haul airline pilots during night and non-night duties. In addition, the correspondence between self-rated manifest and predicted latent sleepiness was examined in the two groups. Methods Twenty-two drivers and 33 pilots participated. Their working hours, sleep, on-duty sleepiness, and use of sleepiness countermeasures were measured in naturalistic conditions. Predictions of latent sleepiness were based on the measurements of working hours and sleep using the Sleep/Wake…
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…
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 …
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…
The Role of Parental Communication and Emotional Intelligence in Child-to-Parent Violence
2019
In recent years, cases of child-to-parent violence (CPV) have increased significantly, prompting greater scientific interest in clarifying its causes. The aim of this research was to study the relationship between styles of family communication (open, offensive and avoidant), emotional intelligence or EI (attention, repair and perceived emotional clarity) and CPV, taking into account the gender of the aggressors. The participants of the study were 1200 adolescents (46.86% boys) between the ages of 12 and 18 enrolled at secondary schools in the Autonomous Communities of Andalusia and Valencia (M = 13.88, SD = 1.32). A Multivariate Analysis of Variance (MANOVA, 3 ×
