Informing in-season tactical periodisation in team sport: development of a match difficulty index for Super Rugby

In team sports, tactical periodisation refers to the planned manipulation of training loads with the aim of prioritising athlete readiness for matches of greatest importance. Although monitoring of athletes’ physical condition is often used to inform this planning, the direct influence of external factors on match difficulty has not been well quantified. In this study, a ‘match difficulty index’ (MDI) for use in Super Rugby was developed, based on the influence imparted by five external factors on previous match outcomes. Specifically, information relating to match location, days break between matches, time-zone change and opposition ladder position (both current and previous year) were collected for matches played during the 2011–2013 Super Rugby seasons. Logistic regression analyses were used to assess the importance of each of these factors with respect to match outcome (win/loss), with opposition ladder position and match location (home, domestic away or international) exerting the greatest influence on match difficulty. Three separate cross-validated models were constructed, with match outcome classification performance reported as 66.2%, 65.5% and 63.7% respectively. The three MDI models emanating from this study can each be used to inform tactical periodisation program design both prior to and during the regular season.     

Design and evaluation of a personal digital assistant- based alerting service for clinicians.

PURPOSE: This study describes the system architecture and user acceptance of a suite of programs that deliver information about newly updated library resources to clinicians' personal digital assistants (PDAs). DESCRIPTION: Participants received headlines delivered to their PDAs alerting them to new books, National Guideline Clearinghouse guidelines, Cochrane Reviews, and National Institutes of Health (NIH) Clinical Alerts, as well as updated content in UpToDate, Harrison's Online, Scientific American Medicine, and Clinical Evidence. Participants could request additional information for any of the headlines, and the information was delivered via e-mail during their next synchronization. Participants completed a survey at the conclusion of the study to gauge their opinions about the service. RESULTS/OUTCOME: Of the 816 headlines delivered to the 16 study participants' PDAs during the project, Scientific American Medicine generated the highest proportion of headline requests at 35%. Most users of the PDA Alerts software reported that they learned about new medical developments sooner than they otherwise would have, and half reported that they learned about developments that they would not have heard about at all. While some users liked the PDA platform for receiving headlines, it seemed that a Web database that allowed tailored searches and alerts could be configured to satisfy both PDA-oriented and e-mail-oriented users.     

Self-image and self-awareness: Group activities

As young children develop both physically and emotionally, it is important for adults to present opportunities to them for discussion and reflection upon their growth. The activities below suggest five creative ways to help foster a positive self-image and boost self-awareness. Baby Talk, The Birthday Chair, and Chronicle Growth Chart aid young children in their awareness of the process of growth. Music Pictures introduces a mode for self-expression. Dial-a-Parent integrates the family into the school environment. Children should enjoy the time spent devoted to studying themselves.These activities are from the bookThe Elementary Guidance Connection Charles C. Thomas, Springfield, IL.     

拯救生命的给予

大多数的人总是倾向于临渴挖井而非居安思危,总觉得那些不幸之事不会降临到自己身上,但是大家有没有想过,也许有一天躺在病床上苦苦等待别人救助的会变成我们自己或者我们亲友?我是那些幸运儿之一,现在轮到我去帮助别人了。我最近进行了一次奇妙的旅行,刚从南非的德班回来,我在那里参加了第19届世界移植运动会。自1996年起,我就一直有参加这个移植运动会。无论怎么看,我
