The purpose of this investigation was to prospectively examine the relationship among self-presentational concerns and pre-game affective states among middle and high school aged football players. Methods： American football players （n = 112; mean age = 15.57 years） completed a measure of self-presentational concerns （SPSQ, McGowan, et al., 2008） a week prior to the measurement of selected pre-game affective states （i.e., attentiveness, self-assurance, serenity, and fear）. Results： Regression analyses revealed that concerns about appearing athletically untalented negatively contributed to the significant prediction （p 〈 0.001） of pre-game attentiveness, /3 = -0.43, Radj ^2 19.5% （p 〈 0.001）, and self-assurance, /3 = -0.38, R^dj = 11.9% （p 〈 0.01）. Conclusion： These findings highlight the importance of reducing self-presentational concerns in promoting positive pre-game mental states that likely impact the quality of athletes＇ competitive play and experience.

ZIKV was first detected in 1947 and only 14 human infection cases were reported until 2007. This virus was previously observed to cause only mild flu-like symptoms.However, recent ZIKV infections might be responsible for the increasing cases of neurological disorders such as GuillainBarre′ syndrome and congenital defects, including newborn microcephaly. Therefore, researchers have established several animal models to study ZIKV transmission and pathogenesis, and test therapeutic candidates. This review mainly summarizes the reported animal models of ZIKV infection, including mice and non-human primates.展开更多
