Safety Integrated Model-training (SIM-t) and its evaluation: A safety training proposal for mechanical companies
No full textIn the EU-28, the number of occupational accidents is still too high, with serious social and economic consequences. We have devised an intervention called Safety Integrated Model-training (SIM-t) with the aim of unifying the most effective training methods for adults in a single proposal. SIM-t involves the use of audiovisual materials (ad hoc products for each company), a participatory approach, and regular and lasting reinforcement in daily practice. The training intervention is divided into several sessions over several weeks. For its evaluation, we conducted a longitudinal study (September 2017–April 2018), with the participation of workers (n = 185) from mechanical companies in northern Italy. Measures relating to knowledge, attitudes, behaviours, perception of the health, and safety climate were collected at baseline and in subsequent follow-ups. Overall, the participants’ average safety performance at the end of the training was significantly better than the initial level. In summary, the SIM-t and its evaluation methodology are an integrated intervention proposal providing companies with a safety training protocol and a test of its effectiveness. The contents that emerged from the study suggest extending this training intervention and the evaluation of its effectiveness to different contexts

Maximally superintegrable systems in flat three-dimensional space are linearizable
Full text linkAll maximally superintegrable Hamiltonian systems in three-dimensional flat space derived in the work of Evans [Phys. Rev. A 41, 5666-5676 (1990)] are shown to possess hidden symmetries leading to their linearization, likewise the maximally superintegrable Hamiltonian systems in two-dimensional flat space as shown in the work of Gubbiotti and Nucci [J. Math. Phys. 58, 012902 (2017)]. We conjecture that even minimally superintegrable systems in three-dimensional flat space have hidden symmetries that make them linearizable
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Effects of exergames on mood and cognition in healthy older adults: A randomized pilot study
Full text link: The elderly population is increasing and the implementation of stimulating training to promote active aging has become a research issue. This study aimed at investigating the effects of a cognitive-motor exergame training on cognitive functions and mood, in healthy older adults. A randomized controlled pilot study was conducted to compare a cognitive-motor exergame training with a passive control group. The training consisted of 8 sessions of 45 min each, including 10 interactive activities focused on several cognitive functions such as memory, processing speed and executive functions, all requiring motor planning and execution. A total of 57 participants were administered a battery of cognitive tests before and after the training. A mixed-effect ANOVA with group (experimental vs. control) as between factor and time (pre-and post-test) as within factor, was performed to evaluate the effect of the exergame training on cognitive abilities and mood. Results showed significant interaction effects in processing speed [STROOPC: F (1,53.4) = 9.04, p = 0.004, R 2 = 0.82], inhibition [3backs' false alarms: F (1,47.5) = 5.5, p = 0.02, R 2 = 0.79], and mood [Beck Depression Inventory: F (1,55) = 4.15, p = 0.04, R 2 = 0.6]. Even though post-hoc analyses did not provide statistical evidence supporting the interactions, overall data showed a trend toward better scores only for the experimental group, suggesting a potential improvement in information processing speed, working memory and mood. Exergaming may be a motivating and enjoyable approach to healthy and active aging
