Spectral broadband anastigmatic Wadsworth imaging spectrometer.

A new advanced optical design based on the Wadsworth mounting for a broadband stigmatic, coma-free practical spectrometer with high imaging quality is presented. By the addition of an inclined cylindrical lens with a wedge angle, the stigmatic imaging conditions in a broad waveband have been obtained by our analysis. An example which presents excellent optical performances over a spectral broadband of 380nm centered at 570nm has been designed to certify the analysis.

Planning skills moderate the intention-planning cognitions-behaviour relation: a longitudinal study on physical activity in Chinese adolescents.

Our objective is to examine the role of planning skills for translating intentions into physical activity via planning cognitions. A study with 534 adolescents was conducted. Over 4 weeks, intention, planning cognitions (prospective anticipation of when, where, and how to perform activities), planning skills (successful past planning experiences), and physical activity were assessed.

The Importance of Autonomous Regulation for Students' Successful Translation of Intentions into Behavior Change via Planning.

Physical activity has a high prevention potential in adolescents. This study investigated the relations between physical activity and intention, autonomous regulation, and planning. We hypothesized that planning mediates the relationship between intention and behavior and that this mediation should depend on the level of autonomous regulation.

Stage-matched minimal interventions to enhance physical activity in Chinese adolescents.

Purpose: Interventions to improve physical activity (PA) might be successful when treatments are matched to the requirements of the recipients, in particular to their stage of change. This intervention study examines PA in Chinese high school students whose stage of change at the beginning of the study was identified.

Methods: Two minimal interventions (1 hour) were provided: resource communication and strategic planning.
