The Relationship Between Resilience, Stress & PTSD

Post-traumatic stress disorder (PTSD) is characterized by intrusive thoughts or memories of the traumatic event that hinder daily life activities of individuals with a PTSD diagnosis. Stress exposure has further been shown to exacerbate PTSD symptoms. Given that resilience has been shown to buffer levels of stress, the current study investigated whether resilience may moderate the relationship between stress and PTSD symptoms. Eighty-one participants over the age of 18 were recruited from the University of Missouri-Saint Louis and St. Louis community. Participants completed 3 self-report measures of resilience, exposure to stressful life events (e.g., Have you ever been in a car accident before?), and PTSD symptoms. In support our first hypothesis, we found that stress exposure was associated with greater PTSD symptoms (b = 2.08, t(77) = 5.02, p \u3c .001). However, resilience did not moderate the relationship between stress exposure and PTSD symptoms (B = -0.01, p = .68). Future studies may examine the influence of medications on PTSD, chronic stress, and resilience

Corporal Punishment of Children in Nine Countries as a Function of Child Gender and Parent Gender

Background. The purpose of this paper is to contribute to a global perspective on corporal punishment by examining differences between mothers' and fathers' use of corporal punishment with daughters and sons in nine countries. Methods. Interviews were conducted with 1398 mothers, 1146 fathers, and 1417 children (age range = 7 to 10 years) in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Results. Across the entire sample, 54% of girls and 58% of boys had experienced mild corporal punishment, and 13% of girls and 14% of boys had experienced severe corporal punishment by their parents or someone in their household in the last month. Seventeen percent of parents believed that the use of corporal punishment was necessary to rear the target child. Overall, boys were more frequently punished corporally than were girls, and mothers used corporal punishment more frequently than did fathers. There were significant differences across countries, with reports of corporal punishment use lowest in Sweden and highest in Kenya. Conclusion. This work establishes that the use of corporal punishment is widespread, and efforts to prevent corporal punishment from escalating into physical abuse should be commensurately widespread

Dielectric Dispersion at Microwave Frequencies of Some Low Loss Mixed Oxide Perovskites This paper reports the dielectric permittivities of several low loss ceramics of A(B1 1/2 B2 1/2 )O 3 mixed oxide perovskites

/2 )O 3 (SGT), and their modified compositions 0.7Sr(Al 1/2 Nb 1/2 )O 3 -0.3NdGaO 3 (SAN-NG) and 0.7Sr(Al 1/2 Ta 1/2 )O 3 -0.3NdGaO 3 (SAT-NG), measured at microwave frequencies. Measurements of the frequency-dependent dielectric constant and loss tangent are reported. Their loss tangent values are on the order of 10 −4 to 10 −5 , which can not be evaluated by the traditional reflection/transmission spectra or impedance measurement techniques. A parallel-plate dielectric resonance method was adopted for dielectric measurements for such low loss materials. The frequency spectra of dielectric constants and loss tangents of were investigated by the well known classical oscillator model
