SummaryThe method of isonymy to estimate inbreeding is applied to the historical population of the Quebrada de Humahuaca (Province de Jujuy, Republic of Argentina). Data from the baptismal records of the Parochial Church of Humahuaca from 1734 to 1810 were grouped into two periods, 1734–72 and 1773–1810. The analysis was carried out twice: (a) using the surnames exactly as they were registered; (b) combining homonymous surnames which were pronounced or spelt in a similar way. The random and non-random components of inbreeding have been investigated through different methods. There were no significant differences between the results of the two analyses, nor between the expected and observed isonymy. The value of Flies somewhere between those for offspring of first cousins once removed and second cousins once removed. There is a tendency for F and its components to increase through time. It is concluded that the high altitude aboriginal population of Humahuaca Parish must have behaved as a panmictic unit.
Cycling and all categories of para-cycling including Handbike are cyclical sports, that is, sports characterized using a specific skill, continuous skill. To separate competitions between cyclists and paracyclists, there is a classification system. The study in aims to design one activity performance and training, to eliminate the division into categories between cycling and para-cycling (Handbike), since this does not favour the integration and sporting inclusion of the two groups of athletes. The differences in performance will be identified between: cyclists and paracyclists with spinal cord injury or amputation of the lower limbs (H). Then will proceed to design and verify an activity capable of making the two categories compete and train together, eliminating the differences in performance through the use of a "counterweight" and using a mixed training, HIIT (High Intensity Interval Training) and Endurance. The sample taken into consideration is composed of 5 cyclists and 5 paracyclists (H) aged between 19 and 38 years. To achieve the goal, the study was based on the method of analysing the scientific literature, detecting the various parameters in the race and using mathematical statistical methods, such as Multiple Regression and the T-Test for independent samples. The analysis of the results of this study shows that; between cyclists and para-cyclists who participated, there are substantial differences in performance, thanks to the data obtained from multiple regression, in which we find an Rsquared value that is .999975008, also the only positive coefficient among the independent variables is that of power (6.760634791). This means that of all the reported values, it is the only one that directly affects performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
