These findings provide preliminary evidence that a videogame has the potential to influence key cognitive and motivational variables and can be an engaging means to deliver a cigarette and marijuana prevention intervention.Īdolescents cigarettes marijuana prevention videogame. 5 Main dimensions of prototype 3 Main dimensions of present design C. Overall, the players provided positive reports of their experience with the smokeSCREEN videogame prototype.
009) use from pre- to post-gameplay that were characterized by large effects and (2) nonsignificant trends in the expected direction emerged for changes in self-efficacy and perceived norms related to both cigarettes and marijuana that were characterized by medium-large effects. One-way repeated-measures analyses of variance (ANOVAs) were conducted.įindings are (1) improvements in knowledge for both cigarette (Wilks' λ = 0.62, F(2, 23) = 7.21, P =. Ratings of gameplay experience were collected after the 2 weeks of gameplay. Assessments of knowledge, self-efficacy, attitudes, perceived norms, and intentions related to cigarette and marijuana prevention were collected at baseline and 2-week and 12-week follow-ups. The prototype is 64 m (210 ft) long with a maximum diameter of 3.8 m (12.5 ft), can be installed in waters more than 25 m (82 ft) deep thanks to its flexible mooring system and makes use of proven. Participants played four 1-hour gameplay sessions over a 2-week period. This study employed a 1-group pretest-posttest design with 25 adolescent boys and girls aged 11 to 14 years (M age = 11.56, SD = 0.77) who had never tried cigarettes or marijuana. The effect of prototype difficulty and semantic similarity on the prototype activation. The authors also explored participants' gameplay experience. The purpose of this study was to conduct a preliminary test of the efficacy of a role-playing videogame prototype, smokeSCREEN, aimed at developing knowledge and behavioral skills associated with primary prevention of cigarette and marijuana use. Product validation remains challenging due to vertical TWC uncertainties and the typically coarse spatio-temporal resolution of the GEO data.Videogames are becoming increasingly popular to deliver health interventions however, their role in the primary prevention of cigarette and marijuana use has not yet been evaluated. The products show the greatest capability for discriminating TWC ≥ 0.5 g m −3. Discrimination of HIWC was more challenging at night with IR-only information. The daytime HIWC probability was found to agree quite well with TWC time trends and identified extreme TWC events with high probability. The products were demonstrated using data from several campaign flights and validated using a subset of the satellite–aircraft collocation database. Statistical fits between collocated TWC and GEO satellite parameters were used to determine the membership functions for the fuzzy logic derivation of HIWC probability.
Three satellite-derived parameters were determined to be most useful for determining HIWC probability: (1) the horizontal proximity of the aircraft to the nearest overshooting convective updraft or textured anvil cloud, (2) tropopause-relative infrared brightness temperature, and (3) daytime-only cloud optical depth. This paper describes a prototype method for detecting HIWC conditions using geostationary (GEO) satellite imager data coupled with in situ total water content (TWC) observations collected during the flight campaigns. Three airborne field campaigns were conducted in 20 to better understand how HIWC is distributed in deep convection, both as a function of altitude and proximity to convective updraft regions, and to facilitate development of new methods for detecting HIWC conditions, in addition to many other research and regulatory goals. Previous aviation industry studies have used the term high ice water content (HIWC) to define such conditions. Recent studies have found that ingestion of high mass concentrations of ice particles in regions of deep convective storms, with radar reflectivity considered safe for aircraft penetration, can adversely impact aircraft engine performance.
