Wider is better but sharper is not: optimizing the image of camera-monitor systems

2021

The replacement of rear-view mirrors with camera-monitor systems introduces new opportunities for design, such as altering the image quality and the rearward field-of-view. We investigated how the image quality and field-of-view might affect the distance and time-to-contact estimation of other vehicles. Eighty-six subjects estimated either their egocentric distance to a stationary vehicle (Experiment I) or the time-to-contact to an approaching vehicle (Experiment II). Throughout the experiments, the pixel density and either the field-of-view or the viewing condition varied. A larger field-of-view increased distance estimation accuracy and confidence. Reduced pixel density led to larger esti…

‘I think I will need help’: A systematic review of who facilitates the recovery from gender‐based violence and how they do so

2020

Context A key to advancing the eradication of gender-based violence (GBV) is knowing how to recover from it. Objective To identify the changes that are indicators of having overcome GBV and determine the role of various support networks. Search strategy We systematically searched Web of Science. Inclusion criteria Publications whose abstracts contained a minimum of two of the following words: (a) support or network or solidarity, (b) violence and (c) recovery or healing. Data extraction and synthesis Of the 273 documents retrieved, 52 were used using a narrative synthesis approach. Main results For recovery, women must reconnect with themselves, with their environment and with the world in …

Technology management, networking positions and work/life boundaries among working adult students

2021

In this digitalised world, crossing boundaries between life domains is becoming increasingly easy. We are constantly faced with the need to define whether we are online or offline, and technology management is now an integral part of daily life. Technology management, which is affected by the individual's networking position, has different components: connectivity management, online self-presentation and privacy management. The objective of this study is to explore technology management strategies among working adult students. The study identifies three networking positions: socio-affective enthusiasts, context-contingent pragmatists and pragmatic avoiders. These three groups have specific …

A questionnaire to assess parental perception of barriers towards active commuting to school (PABACS): Reliability and validity

2019

Abstract Introduction Parental barriers are a key factor to determine physical activity behaviors, such as active commuting to school in young people. The purpose of this study was to test the reliability and validity of a questionnaire which addresses parental barriers towards active commuting to school. Methods This paper describes the development, following the Delphi method, and the validation of a Likert-scale questionnaire of 23 items (Parental Perception of Barriers towards Active Commuting to School (PABACS)) designed to determine the main parental barriers. These barriers are categorized into 3 scales (general, walking, and cycling barriers) and the overall questionnaire. A total o…

MAVIE-Lab Sports: a mHealth for Injury Prevention and Risk Management in Sport

2018

International audience; Smart-phones technology and the development of mHealth (Mobile Health) applications offer an opportunity to design intervention tools to influence health behavior changes. The MAVIE-Lab is a mHealth application including a DSS (Desicion Support System) to assist in the personalized evaluation of HLIs (Home, Leisure and Sport Injuries) risk and to promote the adoption of prevention measures. MAVIE-Lab Sports will be the first module of the mobile application. The purpose of this PhD project is to improve a particular module of MAVIE-Lab, devoted to sports (MAVIE-Lab Sports), in different aspects: statistical modeling, design and ergonomics. It also aims to evaluate sy…

Ergonomic Indicators and Physical Workload Risks in Food Production and Possibilities for Risk Prevention

2021

The food industry is the most important and largest manufacturing industry in Latvia, producing almost a third of all manufacturing output. Employees in a food production enterprises are exposed to a variety of ergonomic risks: monotonous work movements that can be repeated up to 1000 times a day, overloads that exceeds 30 kg in lifting and moving operations, forced working postures, fast work pace. The aim of the study was to identify ergonomic indicators related to physical load for packers in one medium-sized company producing potato starch in Latvia. When summarizing the results of the survey on burden-lifting rates, it should be noted that, in a shift, 30% of packers lift the burden fr…

Post-license Education for Novice Drivers: Evaluation of a Training Programme implemented in Spain

2006

Abstract Introduction This study evaluated the implementation of a second phase training program for novice drivers in Spain, which puts the primary focus of the training on the higher hierarchical levels of driver behavior. Method Two hundred and sixty-three participants took part throughout the study, which was implemented as an experimental design with the test and control groups assessed before and after the one day safety training. Measurement of the impact of the training program focused on the participants' self-evaluation and self-reporting of some driving behavior indicators related to accident risk. Results Data analysis showed a change in the expected direction in the scale relat…

Childhood trauma and substance use underlying psychosis: a systematic review

2020

[EN] Background: Schizophrenia spectrum disorders (SSD) are mental diseases caused by a combination of genetic susceptibility and a number of environmental factors. Among these factors, the role of traumatic events suffered in childhood, as well as that of substance use, have been of particular research interest. Objectives: To conduct a systematic review to clarify whether there is an interaction between childhood trauma and substance use related to the diagnosis or symptoms of SSD. It was also the objective of this review to collate the associations that may exist between the three variables of the study (trauma, substance use and psychosis). Methods: We conducted a systematic search resu…

To See Oneself as Seen by Others

2019

Abstract This article develops a new phenomenological analysis of the interpersonal motives and structure of shame. I pursue the argument that shame is rooted in our desire for social affirmation and conditioned by our ability to see ourselves as we appear to others. My central thesis is that shame is what we feel when, due to some trait or action of ours, we come to perceive ourselves as fundamentally despicable and non-affirmable. By showing how our urge for affirmation fuels and informs our self-perception in shame, the analysis provides a better understanding of the simultaneously interpersonal and personal character of shame. Furthermore, it sheds new light on some central aspects of s…
