A Monte Carlo-aided design of a modular 241Am-Be neutron irradiator
2013
Monte Carlo studies aimed at designing a modular 241Am-Be neutron irradiator for testing neutron detectors and personal dosimeters and processing large volume samples are reported in this study. The evaluation of the shapes and thicknesses of the moderator and shielding materials was carried out by a MCNP5 Monte Carlo simulation code. The reliability of the simulation was experimentally verified by the activation of gold foils and TLD dosimeter measurements in an irradiation cell placed at the center of the test configuration.
Interrater reliability of ultrasound in the diagnosis of sialolithiasis
2019
The aim of this study was to assess the interrater reliability of ultrasound for diagnosing sialolithiasis. A total of 100 consecutive patients with signs of obstructive sialadenopathy were evaluated. The patients all underwent ultrasound examinations in a standardized manner conducted by one specialist with extensive experience in the management of salivary gland disorders and proficiency in head and neck ultrasonography. The video recordings were sent to six colleagues with comparable experience without providing any further information about the patients' medical history and physical examination. The overall agreement between the seven observers was substantial, with a κ of 0.765 for th…
Evaluation of the effectiveness of occupational injury prevention programs at the company level
2013
The objective was to evaluate the effectiveness of an occupational injury prevention program, known as the Preferential Action Plan (PAP), focused on companies with high incidence rates of occupational injuries. We studied 1189 companies in the industrial, construction and services sectors between 1999 and 2007 in the Valencia region (Spain). Our sample included 507,262 workers, among whom 44,250 non-fatal occupational injuries with at least a workday lost were registered. Companies included in a PAP program were divided into three intervention groups, according to the year that each company entered into a PAP (2000, 2001, and 2002). We calculated annual percentage change in incidence rates…
Validation of the Walking Behavior Questionnaire (WBQ): A tool for measuring risky and safe walking under a behavioral perspective
2020
Abstract Introduction Although daily walking implies several potential benefits for the health and well-being of people, and, besides the raise of more “walkable” cities, it is currently being promoted as an active transportation means that is rich in benefits for its users, road risks affecting pedestrians, together with their high vulnerability to suffer severe injuries as a consequence of traffic crashes, have turned into a relevant concern for both policymakers and public health practitioners. In this regard, risky and positive (proactively safe) behaviors have acquired a substantial relevance for the study and prevention of traffic causalities involving different road users, including …
Subjective Well-Being in Sports Coaches
2022
<p>The purpose of the study is to analyze the structure of the psychological determinants of subjective well-being and identify the most significant set of determinants that form the resources of the psychological well-being in sports coaches. This parameter is important due to objective conditions, which significantly increases stress and reduces the quality of life of subjects of professional sport. The participants were 200 professional sports coaches (89 women, 111 men), M<sub>age</sub>=39 years, M<sub>exprience</sub>=12 years. The psychological determinants were measured with the Brief Differential Perfectionism Inventory (Zolotareva et al, 2021), the Gene…
Organisational climate and employee health outcomes: a systematic review
2019
Organisational climate, particularly safety climate, has been documented as a crucial element in promoting occupational health and safety. However, most previous studies have focused more on safety issues (e.g., injuries and accidents) rather than health outcomes (e.g., illnesses, stress, etc). A comprehensive review is also lacking in relation to understanding the organisational climate–health relationship between different levels of analysis, different data sources and different analytical procedures. We conducted a systematic review to investigate previous scholarly contributions to organisational climate and health. The reviewed articles were obtained from three databases: ISI Web of Kn…
A replication study on the intuitiveness of programming language syntax
2023
AbstractIn this article, we present a replication of an empirical experiment that evaluates intuitiveness and comprehensibility of keywords relating to different concepts in programming languages, originally conducted by Stefik and Gellenbeck. Novice programmers face many barriers when learning programming. One of these barriers is syntax, which for many languages is not designed based on empirical evidence. The purpose of the experiment was to provide more empirical evidence on the subject, to find out if the results of the original experiment can be replicated and if conducting the experiment in an environment where English is not the native language affects the results. The results of ou…
Does reviewing experience reduce disagreement in proposals evaluation? Insights from Marie Skłodowska-Curie and COST Actions
2021
Abstract We have limited understanding of why reviewers tend to strongly disagree when scoring the same research proposal. Thus far, research that explored disagreement has focused on the characteristics of the proposal or the applicants, while ignoring the characteristics of the reviewers themselves. This article aims to address this gap by exploring which reviewer characteristics most affect disagreement among reviewers. We present hypotheses regarding the effect of a reviewer’s level of experience in evaluating research proposals for a specific granting scheme, that is, scheme reviewing experience. We test our hypotheses by studying two of the most important research funding programmes i…
Reliability of adapted version of Italian Label tobacco Impact Index for the adolescent: ALII
2017
OBJECTIVE: The aim of this study is to assess the reliability of the Adolescent Label Impact Index (ALII) , it is an adolescent adapted version of Italian LII of the tobacco products warnings. MATERIAL AND METHODS: A sample including students aged 13-15 years was considered. The ALII is constructed by 4 items: salience, harm, quitting and forgo. The questionnaire was self-administered to study participants twice with 3 days between each administration (T1 and T2) to measure reliability. The internal consistency using Cronbach's alpha and Corrected Item-Total Correlations (CITC) and the test-retest reliability applying Pearson's correlation were computed. RESULTS: Cronbach's alpha ranges fro…
Toward farm-level health management of wind turbine systems: status and scope for improvements
2018
An outline of health management for OWFs has been detailed in this chapter with description of various important elements. The need for such farm level management is explained and benefits are discussed. Key gaps to be filled in order to realize such a system are identified. The proposed health management system is mainly based on the existing knowledge of fleet-level management in the aerospace sector. Health management is much broader than CM; there are a number of aspects beyond the prognostics capabilities that are to be designed in order to arrive at a comprehensive maintenance management scheme. A comprehensive maintenance program that is sensitive to the health of the assets and adap…
