Design of a safety training package for migrant workers in the construction industry
2021
Abstract The construction sector is known as a high-risk sector with many safety challenges. It is also characterised by a large number of migrant workers and these workers report higher accident rates than native workers. This paper presents the design of the CSTP (Construction Safety Training Programme). The CSTP is a theory-based training program aimed at improving safety behaviours in construction sites acknowledging the particular challenges migrant workers face. Based on second and third generational models of training, we developed a training program that addresses the challenges faced by migrant workers in the construction industry, namely language and cultural barriers, times press…
Human Reliability Analysis to support operational planning of an experimental facility
2015
This paper reports the results obtained by using different techniques of Human Reliability Analysis (HRA) to identify potential operator errors at the SPES (Selective Production of Exotic Species) facility, a second generation Isotope Separation On Line (ISOL) plant for advanced nuclear physic applications. The paper presents scoping-level HRA applications, with the main goal to evaluate the applicability of HRA techniques for the specific domain. In particular, two aspects challenge a standard HRA. First, the facility is under construction so that a number of aspects related to its operation (e.g. procedures and operator interfaces) are still under definition. Second, the context of operat…
Ex vivo measurement reliability using two different cbct scanners for orthodontic purposes
2012
Background There are many cone beam computed tomography (CBCT) scanners available on the market: detector technology, algorithm precision, and scanner settings influence image quality. The aim of this study was to compare the accuracy of linear measurements made on images of the same sample obtained using two different CBCT scanners. Methods Twenty-eight linear measurements between orthodontic anatomical landmarks that were marked with gutta-percha points on a fresh sacrificed lamb head were taken three times. The head was scanned with two CBCT scanners using different scanning parameters. Digital Imaging and Communications in Medicine (DICOM) images were reconstructed and the same measurem…
Attribute based access control scheme with controlled access delegation for collaborative E-health environments
2017
Abstract Modern electronic healthcare (e-health) settings constitute collaborative environments with complex access requirements. Thus, there is a need for sophisticated fine-grained access control mechanisms to cater these access demands and thereby experience the full potential of e-health systems. In order to realize a flexible access control scheme, integrating access delegation is of paramount importance. However, access delegation has to be enforced in a controlled manner so that it will not jeopardize the security of the system. In this paper, we addressed this issue through proposing an attribute based access control scheme integrated with controlled access delegation capabilities. …
Strategies to exiting the COVID-19 lockdown for workplace and school: A scoping review
2021
Highlights • Epidemiological conditions should be monitored and enforced. • COVID-19 must be under control below thresholds of safeguards. • Testing, contact tracing, and isolation strategies are essential components to ease the lockdown. • The maintenance of social distancing measures is an overarching mitigation strategy. • The benefit gained from the implementation of social distancing was evident.
Autochthonous microalgae grown in municipal wastewaters as a tool for effectively removing nitrogen and phosphorous
2020
Abstract Microalgae have promising applications in wastewater treatment because of their ability to use inorganic compounds such as nitrates and phosphates as nutrients for their growth. Microalgae are applied to the secondary and tertiary bio-treatment with two benefits: i) pollutants removal from wastewater; ii) production of microalgal biomass, that can be exploited as a source of biomass and biomolecules. In the present work, four different microalgal strains (two from culture collections and two isolated from Sicilian littoral) were tested in municipal sewage bioremediation. The sewage of a municipal plant, already processed with primary treatment, was used for the cultivation of micro…
The Cyberspace Threats and Cyber Security Objectives in the Cyber Security Strategies
2013
Threats in cyberspace can be classified in many ways. This is evident when you look at cyber security on a multinational level. One of the most common models is a threefold classification based on motivational factors. Most nations use this model as a foundation when creating a strategy to handle cyber security threats as it pertains to them. This paper will use the five level model: cyber activism, cybercrime, cyber espionage, cyber terrorism and cyber warfare. The National Cyber Security Strategy defines articulates the overall aim and objectives of the nation's cyber security policy and sets out the strategic priorities that the national government will pursue to achieve these objectives…
Distracted driving in relation to risky road behaviors and traffic crashes in Bogota, Colombia
2022
The growing evidence on road distraction during the recent years has shown how road distractions might be playing a relevant role on traffic crash causation. However, the empirical insights about how it works in low- and middle-income countries (LMICs) are really limited so far. The case of Colombian non-professional drivers remains virtually unexplored on this regard. This research aims to assess the effect of road distractions, driving-related issues and road behaviors on the self-reported crashes suffered by drivers in Bogotá, Colombia. To do so, a sample of 659 drivers (64% males and 36% females) with a mean age of 37.9 years (SD = 11.7) was gathered, who answered an online survey on ro…
Reliability and validity of the Home Care STAT (Safety Task Assessment Tool).
2013
Abstract Home care workers are a priority population for ergonomic assessment and intervention, but research on caregivers' exposures to hazards is limited. The current project evaluated the reliability and validity of an ergonomic self-assessment tool called Home Care STAT (Safety Task Assessment Tool). Participants (N = 23) completed a background survey followed by 10–14 days of self-monitoring with the STAT. Results showed that the most frequent task was house cleaning, and that participants regularly performed dangerous manual client moving and transferring tasks. Researcher in-home observations of 14 workers (duration ≤2 h) demonstrated that workers' self-assessments were moderately re…
Driver training interests of a Spanish sample of young drivers and its relationship with their self-assessment skills concerning risky driving behavi…
2013
Abstract Poor driving self-assessment skills (e.g., over-confidence) have been pointed out as an important explanatory factor behind young drivers’ accident involvement. This paper explores (1) what young drivers miss in their training as drivers in order to analyze whether an assessment of one's own driving skills plays an important role in their desire to improve as drivers, and (2) how these training interests are related to an estimate of their self-assessment skills concerning risky driving behavior. For this purpose, a study was conducted using a survey with a blocked sampling design of novice drivers. The survey solicited respondents’ self-report about (1) the contents of training co…
