The authors examined the roles of reasons for living and coping in protecting against suicidal behaviors among 361 Black college students. Results of a path analysis revealed that reasons for living mediated against suicidal ideation through an inverse effect on depression. Results also indicated that greater use of emotion‐oriented coping may lead to suicidal ideation through increased depression and decreased reasons for living, whereas avoidance‐oriented coping protected against suicide. Implications for these results are further discussed. 相似文献

The complete high-order perturbation formulae of spin-Hamiltonian (SH) parameters (g factors gi and hyperfine structure constants Ai , where i = x, y, z) containing contributions from both the crystal-field (CF) and charge-transfer (CT) mechanisms (the latter mechanism is neglected in the widely-used CF theory) are established for d1 ions in rhombic tetrahedra. From these formulae, the SH parameters of Cr5+ ion at the rhombically-distorted tetrahedral P5+ site of Ca2PO4Cl crystal are calculated. The CF and CT energy levels used in the calculation are obtained from the optical spectra of the studied Ca2PO4Cl : Cr5+ crystal. The calculated results showed reasonable agreement with the experimental values. The signs of the hyperfine structure constants Ai and the relative importance of the CT mechanism to SH parameters are acquired from the calculations. 相似文献

Ferroelectric (FE) materials directly convert electrical energy to mechanical energy and are critical to applications such as sensors, transducers, and actuators. The giant electromechanical response is the manifestation of the critical point between the first-order and second-order ferroelectric–paraelectric (FE–PE) transitions. For the simple classic FE lead titanate (PbTiO3), it is commonly accepted that there is a critical point in the temperature–pressure phase diagram separating the first- and second-order FE–PE transitions at zero electric field. Here, we show that the FE-PE transition in PbTiO3 is second-order at zero electric field. We introduce the concept of the invariant critical points (ICP) among three phases, representing the stability of the PE phase with respect to two FE phases in a three-dimensional electric field-pressure-temperature phase diagram of PbTiO3. It is pointed out that the electromechanical response near ICPs is larger than that near the line of critical end points (LCEPs) between two phases. 相似文献

There are various controversies over the measurement of cognitive complexity and few studies concerning its development in adolescents, especially in China. Based on a sample of 234 Chinese adolescents from Grades 7 through 11, the present study first compared 2 instruments and 12 corresponding indices of cognitive complexity—11 traditional and new forms of cognitive complexity scores on the Repgrid, and 1 score on the Role Category Questionnaire (RCQ)—then adopted the most appropriate tool to investigate the development of cognitive complexity. The results showed that the RCQ may have relatively more construct validity than the Repgrid in terms of the assessment of adolescents’ cognitive complexity. Using the RCQ, it was found that adolescents of different grades, gender, peer status, and academic achievement had different levels of cognitive complexity. 相似文献
