HJA Day is "an annual field gathering to share information about research, outreach, education, management, and arts and humanities at the Andrews Forest" (HJ Andrews Experimental Forest, 2015).
HJA Day has no set learning objectives, so the four main research questions were exploratory in nature.
3) What participant outcomes resulted from HJA Day?
In this study we examine participants' goals, experiences, and perceived outcomes at HJA Day to determine how to craft a better learning experience in the future.
The forest serves as a site of major research contributions to the advancement of environmental science, management, policy, and education, and the HJA Program consists of a multifaceted, interdisciplinary group of researchers with more than 85 research projects underway in any given year.
In order to evaluate the validity of the device, HJA compared to DMM or AM, patients attached three devices at the same time in the daytime except while bathing for 7 days (Supplementary S1).
To investigate the influence of the weather or holiday on the duration of PA and determine the minimal required number of days for analysis, the HJA was attached throughout the day except while bathing for 2 weeks.
HJA, AM, and DMM are all triaxial accelerometers that are compact and worn only at the waist.
HJA is a small (40 mm x 52 mm x 12 mm) and lightweight (23.0 g) accelerometer that can continuously monitor the PA for 45 days.
The relationships between the PA evaluated by HJA and DMM or AM were assessed by Spearman's rank correlation, and those between HJA and AM were assessed by Bland-Altman plots.
In the study, the researchers had HJA and control participants observe pictures of objects and scrambled images while they were being scanned by functional magnetic resonance imaging.
Within a subset of the regions found in control participants, HJA showed activity only for tactile objects, suggesting that these regions are specifically involved in successful multi-modal recognition.
