Utilization of Topographic Imagery using Watershed Transformation in Watersheds Prone to Natural Disasters

Indonesia is an archipelago that has abundant natural resources, however, problems arise in the process of utilizing natural resources, namely the emergence of natural disasters that have the potential to cause serious damage in several areas. The threat of floods and landslides in watersheds has become the main focus to be addressed as early as possible with the best solutions and planning. The use of topographic imaging in the field of remote sensing is one solution that is very useful in developing better natural disaster management systems. With the support of the use of the watershed transformation method, this study aims to obtain geographical situation data, both from the flow dimensions and slope conditions that affect the watershed discharge capacity. Thus, the risk of natural disasters can be minimized both from the level of material and non-material damage as early as possible.

Work-Related Flow Inventory: Evidence of Validity of the Brazilian Version

Flow in work is constituted by the positive experiences and mental state experienced during the day-to-day occupational activities. This study aims to adapt and assess the psychometric properties of the Brazilian Version of the Work Related Flow Inventory (WOLF). Participants were a nationwide sample of 640 professional (74% women), aged 19 to 73 years (M = 35.9, SD = 10.5). Confirmatory factor analyses (CFA) supported the oblique three-factor structure (absorption, work enjoyment and intrinsic work motivation) as being the most reliable to the data. Multigroup CFA achieved full measurement invariance for the gender and employment status (autonomous and non-autonomous). Flow dimensions were positively related to occupational self-efficacy and job satisfaction. WOLF presented adequate psychometric properties, suggesting its usefulness in evaluating flow at work in the Brazilian context.

Imagery Intervention to Increase Flow State and Performance in Competition

The purpose of this study was to examine the effectiveness of an imagery intervention for enhancing the experience of flow state and performance in junior athletes. On the basis of previous results, a tailored imagery script was developed to target critical flow dimensions, namely challenge-skills balance, clear goals, concentration on the task, and sense of control. It was hypothesized that the use of cognitive and motivational imagery would increase specific flow dimensions, which, in turn, would enhance flow state and competition performance. Participants in a single-case, multiple baseline A-B design study were four nationally ranked athletes. Following a 6-week baseline phase monitoring flow state and performance and a 6-week intervention phase using relaxation in conjunction with imagery techniques, three participants showed a sustained increase in flow experiences, and all four participants improved their service performance, groundstroke performance, and ranking-list position.
