Catching Disease

چکیده
I am quite aware that anybody doubting the value of vaccines and vaccination for smallpox, to which you refer in this article, is at once written down as an ignorant crank. I have, however, been studying the Registrar-General's figures and other facts relating to smallpox, and I am bound to say, so far, I cannot find anything whatever in favour of the practice. I wish you could help me to find some

Which OIC countries are catching up? Time Series Evidences with Multiple Structural Breaks
Abstract In this paper, income per capita convergence hypothesis is tested in selected OIC countries. For this purpose, we use the time series model and univariate KPSS stationary test with multiple structural breaks (Carrion-i-Silvestre et al. (2005)) over the period 1950-2008. The results show that most OIC countries could not catch up toward USA. Although because of some positive term of tra...
متن کاملWhich Countries are Catching up? New Evidences Using Flexible Fourier Stationary Test
In this paper, we tested the catching-up hypothesis toward the USA using Becker et al. (2006) flexible Fourier KPSS stationary test over the period 1960-2009. The mentioned test could control for unknown number and form of structural breaks using a selected frequency component of a Fourier function. Our results show almost poor countries stay poor and almost rich countries stay rich. South Kore...
متن کاملQuiet eye distinguishes children of high and low motor coordination abilities.
PURPOSE This is the first study to use the quiet eye (QE) as an objective measure of visuomotor control underpinning proficiency differences in children's motor coordination. METHODS Fifty-seven, year 5 primary school children (9-10 yr old) completed the Movement Assessment Battery for Children, Second Edition (MABC-2), while wearing a gaze registration system. Participants were subsequently ...
متن کاملIncreased Throwing Accuracy Improves Children's Catching Performance in a Ball-Catching Task from the Movement Assessment Battery (MABC-2)
The Movement Assessment Battery for Children (MABC-2) is a functional test for identifying deficits in the motor performance of children. The test contains a ball-catching task that requires the children to catch a self-thrown ball with one hand. As the task can be executed with a variety of different catching strategies, it is assumed that the task success can also vary considerably. Even thou...
متن کاملBaseball Catching Patterns Differ According to Task Constraints
We investigated the effect of task constraints on movement patterns and sought to confirm the finding that the combined movement involved in the transition between catching and throwing emerges through self-organization. We conducted two experiments. In Experiment 1, four participants were required to perform two tasks: catch a launched baseball (catching task) and catch the launched baseball a...
متن کاملSkill learning based catching motion control
SKILL LEARNING BASED CATCHING MOTION CONTROL Gökçen Çimen M.S. in Computer Engineering Supervisor: Assist. Prof. Dr. Tolga Kurtuluş Çapın July, 2014 In real world, it is crucial to learn biomechanical strategies that prepare the body in kinematics and kinetics terms during the interception tasks, such as kicking, throwing and catching. Based on this, we presents a real-time physics-based approa...
