Imagery or video feedback : which is the "route" to strategic improvement?

The implementation of imagery and video feedback programs has become an important tool for aiding athletes in achieving peak performance (Halliwell, 1990). The purpose of the study was to determine the effect of strategic imagery training and video feedback on immediate performance. Participants were two university goaltenders. An alternating treatment design (ATD; Barlow & Hayes, 1979; Tawney & Gast, 1984) was employed. The strategies were investigated using three plays originating from the right side by a right-handed shooting defenceman from the blueline. The baseline condition consisted of six practices and was used to establish a stable and "ideal" measure of performance. The intervention conditions included alternating the use of strategic imagery (Cognitive general; Paivio, 1985) and video feedback. Both participants demonstrated an increase in the frequency of Cognitive general use. Specific and global performance measures were assessed to determine the relative effectiveness of the interventions. Poor inter-rater reliability resulted in the elimination of specific performance measures. Consequently, only the global measure (i.e., save percentage) was used in subsequent analyses. Visual inspection of participant save percentage was conducted to determine the benefits of the intervention. Strategic imagery training resulted in performance improvements for both participants. Video feedback facilitated performance for Participant 2, but not Participant 1. Results are discussed with respect to imagery and video interventions and the challenges associated with applied research. KEYWORDS: imagery, video, goaltenders, alternating treatment design.

Letter to Mr. Walsh, Registrar Office, 1836

The man to whom the letter is addressed is Francis Leigh Walsh who was a land surveyor and registrar. Mr. Walsh was born on March 12, 1789 in Harford County, Maryland to Thomas Welsh, a United Empire Loyalist. In 1793, his family moved to Norfolk County and in 1810, Francis succeeded his father as registrar for Norfolk County. During the War of 1812 he served in the local militia and became a captain in 1824. He was the representative for Norfolk in the legislative assembly of Upper Canada from 1820 to 1828 and 1834 to 1836. He became justice of the peace in the London district in 1821 and 1838 in the Talbot district. He died in Simcoe on Oct. 14th, 1884. His son, Aquila Walsh served in the Legislative Assembly of the Province of Canada and in the Canadian House of Commons. Benjamin Hardison was born in Berwick in the Thirteen Colonies (British colonies on the Atlantic Coast of North America) on April 2, 1757 to Thomas Hardison and Mary Chadbourne. He was a farmer, miller and political figure. He was the representative for 4th Lincoln and Norfolk in the Legislative Assembly of Upper Canada from 1797-1800. On January 21, 1800 he married Jane Warren. He served with the American forces during the American Revolution at which time he was taken prisoner and sent to Canada. Later, he settled in Fort Erie where he was a captain in the militia and a justice of the peace for the Niagara district. He operated mills and a distillery in Fort Erie and died there on July 26, 1823. Source: http://en.vionto.com/show/me/Francis+Leigh+Walsh http://en.wikipedia.org/wiki/Benjamin_Hardison

The identification and characterization of inter- and intra-species genetic diversity derived from retrotransposons in humans

Retrotransposons, which used to be considered as “junk DNA”, have begun to reveal their immense value to genome evolution and human biology due to recent studies. They consist of at least ~45% of the human genome and are more or less the same in other mammalian genomes. Retrotransposon elements (REs) are known to affect the human genome through many different mechanisms, such as generating insertion mutations, genomic instability, and alteration in gene expression. Previous studies have suggested several RE subfamilies, such as Alu, L1, SVA and LTR, are currently active in the human genome, and they are an important source of genetic diversity between human and other primates, as well as among humans. Although several groups had used Retrotransposon Insertion Polymorphisms (RIPs) as markers in studying primate evolutionary history, no study specifically focused on identifying Human-Specific Retrotransposon Element (HS-RE) and their roles in human genome evolution. In this study, by computationally comparing the human genome to 4 primate genomes, we identified a total of 18,860 HS-REs, among which are 11,664 Alus, 4,887 L1s, 1,526 SVAs and 783 LTRs (222 full length entries), representing the largest and most comprehensive list of HS-REs generated to date. Together, these HS-REs contributed a total of 14.2Mb sequence increase from the inserted REs and Target Site Duplications (TSDs), 71.6Kb increase from transductions, and 268.2 Kb sequence deletion of from insertion-mediated deletion, leading to a net increase of ~14 Mb sequences to the human genome. Furthermore, we observed for the first time that Y chromosome might be a hot target for new retrotransposon insertions in general and particularly for LTRs. The data also allowed for the first time the survey of frequency of TE insertions inside other TEs in comparison with TE insertion into none-TE regions. In summary, our data suggest that retrotransposon elements have played a significant role in the evolution of Homo sapiens.
