How do young offenders describe their parents?

2001

The study examined (1) what dimensions of parenting would emerge from retrospective reports of parental behaviour, and (2) whether childhood family violence and parental problems are associated with later perceptions of parenting among 89 young male Finnish inmates. The inmates completed the Parent Behaviour Inventory (PBI) and the Conflict Tactics Scales (CTS). Data on childhood family violence and parental problems were obtained from two files. The PBI yielded three factors and the CTS two factors for both mothers and fathers. When the PBI and CTS factors were combined into a principalcomponents analysis, five dimensions of perceptions of parenting emerged: maternal rejection, paternal re…

Comparative ergonomic workflow and user experience analysis of MRI versus fluoroscopy-guided vascular interventions: an iliac angioplasty exemplar ca…

2014

A methodological framework is introduced to assess and compare a conventional fluoroscopy protocol for peripheral angioplasty with a new magnetic resonant imaging (MRI)-guided protocol. Different scenarios were considered during interventions on a perfused arterial phantom with regard to time-based and cognitive task analysis, user experience and ergonomics. Three clinicians with different expertise performed a total of 43 simulated common iliac angioplasties (9 fluoroscopic, 34 MRI-guided) in two blocks of sessions. Six different configurations for MRI guidance were tested in the first block. Four of them were evaluated in the second block and compared to the fluoroscopy protocol. Relevant…

A reanalysis of spinal motion during vibration

1987

Calibrated film of the motion of the lumbar spine during vibration was reanalysed, making use of a number of computer based techniques to improve accuracy and reduce measurement noise. The results demonstrated resonant behaviour at about 4 Hz and indicated that at vibration levels of the order of 1 m/s2 there exists bending of the order of 1° (peak to peak) between adjacent vertebrae in the lumbar spine. The bending is complex and involves phase differences along the spine and possibly a rocking motion of the pelvis.

The occupation of dental assistants (DAs) involves many health risks of the musculoskeletal system due to static and prolonged work, which can lead to musculoskeletal disorders (MSDs). The aim of the study was to investigate the prevalence of MSDs in DAs in Germany. Methods: For this purpose, an online questionnaire analyzed 406 (401 female participants and 5 male participants, 401w/5m) DAs. It was based on the Nordic Questionnaire (lifetime, 12-month, and seven-day MSDs’ prevalence separated into neck, shoulder, elbow, wrist, upper back, lower back, hip, knee, and ankle), and occupational and sociodemographic questions as well as questions about specific medical conditions. Results: 98.5% …

Externalizing behaviour and academic performance – the cross-lagged relationship during school transition

2017

The current study examined the over-time association between externalizing behaviour problems and academic performance during school transition in a cross-lagged design. The main focus was to revea...

Usage des organisateurs anti-entropique dans les documents électroniques : approche expérimentale des fenêtres ponctuelles

1999

International audience; Les documents électroniques permettent de nombreuses manières d'organiser, de présenter et d'accéder à l'information. Une utilisation pertinente de ces options par les auteurs requiert une bonne connaissance des effets que ces choix ont sur la représentation cognitive et les traitements faits par l'utilisateur. Cette approche des documents électroniques, sur la base du concept de représentation mentale, fournit un cadre d'analyse des structures et signaux propres à ce type d'écriture. Parmi ces signaux que nous appelons « organisateurs para-linguistiques » pour les distinguer de leurs équivalents purement textuels, un ensemble est destiné à réduire l'entropie due à l…

The parental bond, resistance to peer influence and risky driving in adolescence

2014

The present study examined the relations between gender, the parental bond, resistance to peer influence, and risky driving. In particular, the mediating role of resistance to peer pressure in the relationship between parental bond and risky driving was examined. The moderating role of gender on these associations was also investigated. The sample comprised 322 adolescents (136 males and 186 females), aged from 16 to 20 years, who were living in northern Italy. Path analysis results showed that the maternal bond only indirectly influenced adolescents’ risky driving, via resistance to peer influence. On the contrary, the paternal bond was neither directly nor indirectly associated with risky…

The lived experience of rescuing people who have driven into floodwater: Understanding challenges and identifying areas for providing support.

2018

Background: Drowning is a major public health issue, with risk increasing during times of flood. Driving into floodwater is a major risk factor for flood-related drowning and injury, and despite widespread public health campaigns, many people continue to undertake this risky behaviour and require rescue. Purpose: We aimed to identify key challenges faced by emergency services personnel when rescuing those who have driven into floodwater, and to identify strategies for supporting rescuers in this important role. Methods: Australian flood rescue operators (N = 8) who had previously rescued a driver who had driven into floodwater participated in semi-structured interviews. Data were analysed u…

Work posture load evaluation in medium size metal processing enterprise in Latvia

2019

Article The aim of this study was to evaluate the exposure of individual workers to ergonomic risk factors associated with upper, lower extremities and trunk WRMSDs and to assess entire body posture for risk of WRMSDs. The company that produces finished metal products (ironing boards) was chosen for the research. Rapid Entire Body Assessment (REBA) was used to assess the entire body posture for risk of WRMSDs. Rapid Upper Limb Assessment (RULA) method was used for ironing boards employees to evaluate exposure of the neck, trunk, arms and legs in relation to physical load. Our study proved that employees are subjected to WRMSDs due to the load on certain body parts during the work: shoulder …

Wpływ pracy zdalnej w warunkach podwyższonego ryzyka na bezpieczeństwo i higienę pracy nauczycieli akademickich w myśl koncepcji work-life balance

2022

W ostatnim czasie praca zdalna zdominowała zadania pracownicze wielu zawodów. Dużym wyzwaniem była dla pracowników, którzy do tej pory nie mieli z nią żadnej styczności. W świetle raportów i dostępnych doniesień pracownicy w różny sposób radzili sobie z sytuacją i warunkami narzuconymi z góry, a wymuszonymi pandemią COVID-19. Również nauczyciele akademiccy byli zmuszeni do dużych zmian, zwłaszcza w aspekcie warunków pracy dydaktycznej. Niniejszy rozdział przedstawia wpływ pracy zdalnej w czasach pandemicznych na szeroko pojęte bezpieczeństwo i higienę pracy nauczycieli akademickich w myśl zasady work-life-balance. Badania wykonano przy pomocy autorskiego kwestionariusza ankietowego wśród lo…
