Does the internet increase the job finding rate? Evidence from a period of expansion in internet use
2021
Abstract We examine the impact of household access to the internet on job finding rates in Germany during a period (2006–2009) in which the share of households with a broadband connection increased by 31 percentage points, and job-seekers increased their use of the internet as a search tool. During this period, household access to broadband internet was almost completely dependent on the availability of a particular technology (DSL). We therefore exploit the variation in DSL availability across municipalities as an instrument for household access to the internet. OLS estimates which control for differences in individual and local area characteristics suggest a job finding advantage of about…

Predicting who fails to meet the physical activity guideline in pregnancy: a prospective study of objectively recorded physical activity in a populat…
2016
Background A low physical activity (PA) level in pregnancy is associated with several adverse health outcomes. Early identification of pregnant women at risk of physical inactivity could inform strategies to promote PA, but no studies so far have presented attempts to develop prognostic models for low PA in pregnancy. Based on moderate-to-vigorous intensity PA (MVPA) objectively recorded in mid/late pregnancy, our objectives were to describe MVPA levels and compliance with the PA guideline (≥150 MVPA minutes/week), and to develop a prognostic model for non-compliance with the PA guideline. Methods From a multi-ethnic population-based cohort, we analysed data from 555 women with MVPA recorde…
An efficient data model for energy prediction using wireless sensors
2019
International audience; Energy prediction is in high importance for smart homes and smart cities, since it helps reduce power consumption and provides better energy and cost savings. Many algorithms have been used for predicting energy consumption using data collected from Internet of Things (IoT) devices and wireless sensors. In this paper, we propose a system based on Multilayer Perceptron (MLP) to predict energy consumption of a building using collected information (e.g., light energy, day of the week, humidity, temperature, etc.) from a Wireless Sensor Network (WSN). We compare our system against four other classification algorithms, namely: Linear Regression (LR), Support Vector Machin…
A Comparison of Anthropometric and Training Characteristics between Female and Male Half-Marathoners and the Relationship to Race Time.
2013
Purpose Lower limb skin-fold thicknesses have been differentially associated with sex in elite runners. Front thigh and medial calf skin-fold appear to be related to 1,500m and 10,000m time in men but 400m time in women. The aim of the present study was to compare anthropometric and training characteristics in recreational female and male half-marathoners. Methods The association between both anthropometry and training characteristics and race time was investigated in 83 female and 147 male recreational half marathoners using bi- and multi-variate analyses. Results In men, body fat percentage (β=0.6), running speed during training (β=-3.7), and body mass index (β=1.9) were related to half-m…
A home-based exercise program focused on proprioception to reduce falls in frail and pre-frail community-dwelling older adults.
2019
Frailty and falls are closely associated with each other as well as with disability, hospitalization, and death. Exercise can reduce these risks in both robust and frail older people. This before-after, non-randomized intervention study assessed a one-year proprioception training program with individual daily home exercises in 564 community-dwelling people aged 70 years and over, with different frailty phenotypes. After the exercise program, we observed a moderate reduction in the mean number of falls, fear of falls, body mass index and body fat percentage in frail and pre-frail participants. These results suggest that a home proprioception program may be a viable alternative to complex mul…
Nutritional Status and Risk Factors for Frailty in Community-Dwelling Older People: A Cross-Sectional Study
2020
Objective: This study aims to assess the relationship that frailty has with nutritional status and functional risk factors in community-dwelling older adults. Methods: Cross-sectional study in community-dwelling older people, independent for walking and without impaired cognition. Frailty was assessed by Fried criteria. Nutritional status was analyzed by the Mini Nutritional Assessment Short Form (MNA-SF), biochemical markers (albumin, total proteins, cholesterol, lymphocytes, and hemoglobin)
Changes in Physical Activity, Motor Performance, and Psychosocial Determinants of Active Behavior in Children : A Pilot School-Based Obesity Program
2020
The obesity epidemic and the decline of fitness among children highlights the need for suitable interventions designed to promote Physical Activity (PA) and healthy habits. The purpose of our pilot study was to assess the feasibility of a school-based program among overweight and obese children, by examining changes in their body composition, PA, physical fitness, and some psychosocial determinants of active behavior. An additional objective was to investigate the reciprocal relationship over time between PA and body image. Self-reported PA and health-related fitness tests were administered to 18 overweight and obese children (11.3 ± 0.4 years), before and after a 6-month intervention inclu…
Vertical FDI Revisited
2003
This study explores how relative skilled-wage premia affect FDI. Contrary to previous studies based on factor endowment differences, we find strong support for vertical FDI, in the sense that more FDI is conducted in countries where unskilled labor is relatively cheap. In addition, we find that relative skill-premia also affect FDI activities that have previously been associated with horizontal FDI, i.e. local affiliate sales. Consequently, the potential effects of changes in the relative wage costs on international production reallocation within MNEs are large. In fact, if not for the 8% rise in the US skilled wage premium relative to the average host country between 1986- 1994, annual US …
A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes
2021
BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…
