Prenatal perfluoroalkyl substance exposure and neuropsychological development throughout childhood: The INMA Project.
2021
Abstract Background Perfluoroalkyl substances (PFASs) have been related to neurodevelopmental toxicity in animals. However, human studies are inconclusive. Objectives To evaluate the association between prenatal PFAS exposure and neuropsychological development during childhood. Methods 1240 mother–child pairs from the Spanish INMA Project were analyzed. Perfluorohexanesulfonic acid (PFHxS), perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), and perfluorononanoic acid (PFNA) were measured in first-trimester maternal plasma. Neuropsychological development was assessed at 14 months, 4–5 and 7 years covering four domains: general cognitive, general motor, attention, and working me…
Bioaccumulation of persistent organic pollutants in the gonads of Barbus barbus (Linnaeus, 1758)
2020
Maps with grey or even white spaces are still present in spite of the fact that persistent organic pollutants (POPs) are at the forefront of research in aquatic toxicology and environmental safety. This is also the case for the Mureș River basin. The intensive use of industrial substances such as polychlorinated biphenyls (PCBs) and pesticides such as organochlorine compounds (OCPs) has caused global contamination of the aquatic environment. In our study we have found very high concentrations of both PCBs (2110-169,000 ng/g lipid weight ΣPCB, 1950-166,000 ng/g lipid weight ΣPCB7) and OCPs (1130-7830 ng/g lipid weight ΣDDT, 47.6-2790 ng/g lipid weight ΣHCH, 5.53-35.6 ng/g lipid weight ΣChlor…
Effect of Prolonged Military Field Training on Neuromuscular and Hormonal Responses and Shooting Performance in Warfighters
2018
Introduction: Previous studies have shown that military field training (MFT) has effects on warfighters’ hormonal responses, neuromuscular performance, and shooting accuracy. The aim of the present study was to investigate the changes in body composition, upper and lower body strength, serum hormone concentrations of testosterone (TES) and cortisol (COR), insulin-like growth factor-1 (IGF-1), and sex hormone binding globulin (SHBG) and shooting accuracy during prolonged MFT. Methods: Serum hormone concentrations, isometric strength of the upper and lower extremities, and shooting performance were measured four times during the study: before MFT (PRE), after 12 d (MID), at the end of MFT (PO…
Strategic Decisions in Task-Oriented Reading.
2015
AbstractAnswering questions from texts are assessment and instructional activities that are frequently used in schools. Nevertheless, little is known about the strategic processes that students take while performing these tasks. We explored the amount and frequency that students initially read of a text before they answered questions pertaining to the material. In a procedure similar to the one used in the PISA (Program for International Students Assessment), one-hundred-seventy students between 7thand 9thgrade read and answered several questions designed to assess task-oriented reading in three specific texts. We recorded on-line indexes that evaluated student behavior (e.g., the amount of…
Changes in Physical Performance During 21 d of Military Field Training in Warfighters.
2018
Introduction Few studies have reported the amount of physical activity (PA) and its associations to physical performance of warfighters during military field training (MFT). The purpose of this study was to investigate changes in neuromuscular performance and PA among male Finnish Army conscripts during a 21-d MFT and to evaluate their recovery during 4 d after MFT. Methods Body composition and physical performance were measured four times during the study (before MFT (PRE), after 12 d (MID), post training (POST) and after 4 d of recovery (RECO)). PA was measured throughout MFT in a group of healthy young male conscripts (n=49) by using a tri-axial accelerometer. The study was approved by t…
Evaluation of occupational physical load during 6-month international crisis management operation
2018
Objectives Generally, operational military duties are associated with a variety of stressors, such as prolonged physical activity (PA). However, limited information is available on the occupational workload or changes in PA during international military operations. Thus, the aim of the study was to investigate the changes in body composition, stress biomarkers, PA, and heart rate (HR) responses of 79 male soldiers during a 6-month international crisis management operation. Material and Methods Measurements were conducted 3 times in South-Lebanon during the operation. Body composition was assessed by the bioelectrical impedance method. Blood samples were analyzed for serum testosterone, sex-…
Neuromuscular Performance and Hormonal Profile During Military Training and Subsequent Recovery Period.
2018
INTRODUCTION Military training loads may induce different physiological responses in garrison and field training and only a little is known about how short-time recovery, lasting a few days, affects neuromuscular fitness and hormonal profile. This study aimed to investigate the effects of garrison and field military service on neuromuscular performance and hormonal profile and to evaluate the effects of a 3-day recovery on those factors. METHODS Twenty healthy male soldiers (20 ± 1 years) participated in the study, which consisted of 4 days of garrison training [days (D) 1-4] and 7 days of military field training (Days 5-12) followed by a 3-day recovery period (Day 15). Serum hormone concen…
Key Issues in EA-Implementation: Case Study of Two Finnish Government Agencies
2009
Enterprise Architecture (EA) is getting more common also in public sector as a means to ensure ‘business’ and IT alignment. This study reports a follow-up and theme interviews of the key actors/informants in two EA projects in public administration offices during and half year after the projects were completed. The early experience shows that the process of establishing a government EA is a tedious and complicated process and this study considers the root causes. Three set of factors are found hindering EA’s potential to operate as a strategic alignment tool: lack of establishing proper EA governance, insufficient support for the development, and inadequate resources to do the former two.
Intra-party heterogeneity in policy preferences and its effect on issue salience: Developing and applying a measure based on elite survey data
2017
Quantitative research on party politics often has to assume that parties are unitary actors with homogeneous policy preferences simply because intra-party heterogeneity is difficult to measure. This article proposes a measure of preference heterogeneity based on surveys of party elites. We draw on Comparative Candidates Survey (CCS) data from 28 elections in 21 developed democracies to quantify intra-party heterogeneity and validate this measure. The usefulness of the measure is demonstrated by studying the effects of intra-party heterogeneity on issue salience. We find support for the hypothesis that heterogeneity regarding a policy issue tends to be negatively associated with the emphasi…
