Role of post mortem computed tomography in diagnosis of upper cervical fractures in child due to road accident: A case report and literature review
2019
The upper cervical spine has unique anatomical features that distinguish it from the remainder of the cervical spine. Its motion segments make up a large amount of total cervical spine motion and, as a result,predispose it to a unique set of injuries. Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to section of the spinal cord. The use of post mortem CT (PMCT), and the subsequent multi-planar and volume rendering reconstruction techniques can provide non-invasive, objective operator-independent imaging data set that may be further reviewed by other specialists. and can substantially add to forensic examinations of the skeleton, especial…
Validation of the swimming competence questionnaire for children
2020
Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequenc…
A new picking algorithm based on the variance piecewise constant models
2022
AbstractIn this paper, we propose a novel picking algorithm for the automatic P- and S-waves onset time determination. Our algorithm is based on the variance piecewise constant models of the earthquake waveforms. The effectiveness and robustness of our picking algorithm are tested both on synthetic seismograms and real data. We simulate seismic events with different magnitudes (between 2 and 5) recorded at different epicentral distances (between 10 and 250 km). For the application to real data, we analyse waveforms from the seismic sequence of L’Aquila (Italy), in 2009. The obtained results are compared with those obtained by the application of the classic STA/LTA picking algorithm. Althoug…
Face and Content Validity of the Pictorial Scale of Perceived Water Competence in Young Children
2022
An international group of experts have developed a pictorial tool to measure perceived water competence for children aged from 5 to 8 years old: the Pictorial Scale of Perceived Water Competence (PSPWC). The aim of the present study was to verify the validity of this tool. In the first part of the study, 120 children were interviewed to investigate face validity of the PSPWC to ensure that all pictorial items were understandable. In the second part of the study, 13 scientific and/or pedagogical international experts were invited to assess the tool’s content validity via an online survey. Face validity results revealed that children were able to understand and sequence correctly the aq…
How University Students Assess Their Water Skills.
2022
The aim of this study was to determine the gender differences between students' actual and perceived water abilities, how respondents assess risk in the described situations, and whether there are gender differences for those situations. The cross-sectional study was conducted on 150 students aged 19–20 years (males, n = 88; females, n = 62) from the faculty of sport and physical education, University of Novi Sad. Using calculated frequencies and estimates, students' self-assessment and actual measures of their swimming and survival skills and their perceived risk of drowning are described. Based on the results, Mann-Whitney U tests were applied. The differences between independent variable…
Alcohol use, aquatic injury, and unintentional drowning : A systematic literature review
2018
Issues Drowning is a global public health issue, and there is a strong association between alcohol and risk of drowning. No previous systematic review known to date has identified factors associated with alcohol use and engagement in aquatic activities resulting in injury or drowning (fatal and non‐fatal). Approach Literature published from inception until 31 January 2017 was reviewed. Included articles were divided into three categories: (i) prevalence and/or risk factors for alcohol‐related fatal and non‐fatal drowning and aquatic injury, (ii) understanding alcohol use and aquatic activities, and (iii) prevention strategies. Methodological quality of studies was assessed using National He…
Changing people’s attitudes and beliefs toward driving through floodwaters : Evaluation of a video infographic
2018
Despite awareness of campaigns such as ‘Turn Around, Don’t Drown’ and the Australian state of Queensland’s ‘If It’s Flooded, Forget It’, people continue to drive through floodwaters, causing loss of life, risk to rescuers, and damage to vehicles. The aim of this study was to develop a video infographic that highlights the dangers of driving through floodwaters and provide safety tips to reduce the risk, and to evaluate its effectiveness in changing the beliefs and intentions of Australian adults toward this risky driving behaviour. This study adopted an online three-wave non-controlled pretest–posttest design. Australian licensed drivers (N = 201, male = 41, female = 160; Mage = 34.10) self…
Assessment of Occupational Health and Job Satisfaction in Workers with Intellectual Disability: A Job Demands–Resources Perspective
2021
In the contexts where people with intellectual disability work, there are factors that determine their job satisfaction. The objective of this study was to test the adequacy of the central assumptions of the Job Demands–Resources (JD-R) theory in workers with intellectual disability employed in different work alternatives. Data from 362 workers in sheltered workshops and 192 workers in supported employment were utilized. The model was contrasted using a structural equation model and a multi-group analysis. The results supported the suitability of the model and confirmed that job demands and job resources evoke two relatively independent processes such as health impairment and motivational p…
From disaster to development : parliamentary debate analysis: Atomausstieg and securitization
2017
Tutkimukseni tehtävänä on selvittää, mitä turvallisuusargumentteja käytettiin Saksan parlamentaarisissa debateissa, jotka koskivat atomivoimasta luopumista vuonna 2011 maaliskuusta kesäkuuhun, jolloin keskustelu oli vilkkainta. Alkupäivämäärä määräytyi Fukushiman ydinonnettomuuden mukaan ja loppupäivämäärän määritteli hetki, jolloin Saksan parlamentti, Bundestag, hyväksyi uusia lakeja liittyen ydinenergian käyttöön ja rajoittamiseen. Ydinenergian käytön rajoittamiseen ja poistamiseen viitataan termillä Atomausstieg. Taustoitan työtä keskustelemalla ensin parlamentaarisista debateista yleensä, sitten turvallistamisesta ja energiaturvallisuudesta. Aineistossani viittaukset Fukushiman ydinonne…
