“…The PRIDE research team handed out surveys to participants, in which teachers agreed for their classrooms to participate in the study. Previous literature found the PRIDE survey questions regarding gambling and substance use to be valid (Metze, 2000; Reiland Consultants, 2018), to be reliable (test–retest coefficients from .814-.851; Metze, 2000), and to have a high interrater agreement (80%) regarding survey question content between survey responders (Craig & Emshoff, 1987). Adams (1994) also compared PRIDE survey estimates with the Monitoring the Future survey and found similar estimates between the surveys.…”

The present study sought to identify psychosocial factors associated with recent gambling (gambling within the past 30 days). The 2016, 2018, and 2020 Parents’ Institute for Drug Education (PRIDE) data sets were pooled and analyzed, consisting of 108,690 adolescents in 13 local public schools. A sizable percentage (13.1%) of adolescents reported gambling in the past 30 days. Multiple logistic regression analyses found differences based on demographic factors, previous substance use, and psychosocial factors. Adolescents at highest risk were male, non-White, in high school; sold drugs; and participated in violent activities in the past 30 days. The study also found worrying rates of substance use. Findings from the present study can inform harm reduction efforts, prevention messaging, and clinical interventions related to adolescent gambling.

“…7 The gyrotron produces high power millimeterwave radiation by bunching of an electron beam in a copper resonant cavity subjected to a magnetic field. 8 When the electron cyclotron resonance frequency is approximately equal to characteristic frequency of the cavity, energy can be transferred from the beam to cavity radiation (for 140GHz the D.C. magnetic field for first harmonic operation is -5 T).…”

Conventional superconducting materials used at liquid helium temperatures have been employed to greatly reduce ohmic power loss in microwave cavities. If suitable high temperature superconductor surfaces can be developed, it could be possible to alleviate constraints due to relatively low energy gaps and limits due to critical fields, and operate at more convenient temperatures with larger thermal margins. These features could be used to improve performance of present superconducting microwave cavity devices. They may also facilitate new applications and device designs at millimeter-wave and far infrared frequencies. Possible cavity and waveguide applications are described. Sensitivity of RF surface resistance to boundaries and nonaligned grains in the material and to small amounts of nonsuperconducting material may be an obstacle to development. Moreover, critical RF fields can be limiting for high power applications. An additional problem is the adverse effect of D.C. magnetic fields.ii
