The article introduces the situation of family therapy and systemic practice in the Czech Republic. It gives an overview of family therapy history and development in the country. Both historical and political background including major transformation events in the last couple of decades are presented so as to explain the contextual frame for major challenges, which Czech family and systemic therapists have been facing in this part of Europe. The current situation of family therapy in the Czech Republic is described in detail with regard to leading figures, major schools, training issues, international exchange and clinical practice in various settings. 相似文献

Antecedents to trust (propensity to trust, perceived trustworthiness) and trust behaviors were examined in relation to team performance in a complex eight-mission military peacekeeping simulation. Teams were colocated or distributed and stayed in the same or transferred to a different context at task transfer. In Experiment 1, an ability and competence factor accounted for most of the variance in perceived trustworthiness and greater perceptions of teammates' abilities/competences predicted posttransfer performance. One's perception of how others perceived one's ability/competence increased over missions. In Experiment 2, propensity to trust did not predict performance; however, trust in others' and one's own ability/competence and trust behaviors predicted performance. At task and/or context transfer, teams produced more monitoring and less cooperating language in their communication. 相似文献

Background: Children with acquired brain injury (ABI) present with high rates of psychological disorders commonly accompanied by deficits in hot and cold executive functions (EFs). Impairments in EFs have been reported to precede mental health problems. Moreover, children who are vulnerable to developing mental health problems in adulthood frequently present with a dysregulation profile in childhood, characterized by impairments in cognitive, behavioral and emotional regulation. Objective: To identify profiles of behaviors associated with impairment in hot and cold EFs and compare injury factors, environmental stressors and dysregulation profile between them. Methods: A latent profile analysis was conducted with 77 children with ABI aged between 6 and 12. Injury factors, child IQ, environmental stressors and the dysregulation profile were compared between these behavioral profiles. Logistic regressions were conducted to predict profile membership. Results: Two profiles were identified: Profile M, with mild deficits (1–2 SD above the mean) in working memory and social skills, and profile C, presenting clinically significant deficits (2–3 SD above the mean) in shift, initiate, working memory, planning and social skills and mild deficits in inhibit, emotional control and task monitor. Proximal environmental stressors (dysfunctional parenting practices, parental stress, parent’s executive dysfunction, anxiety-trait, and depressive symptoms) and dysregulation symptoms predicted profile membership, whereas injury factors, child IQ and distal environmental stressors did not. Conclusion: Following ABI, children with profile C are at risk of mental health problems and present with more proximal stressors. The dysregulation profile may be useful as a proxy for risk for later mental health problems in children with ABI. 相似文献

We model conducting pentagon chains with a multi-orbital Hubbard model and prove that well below half filling, exact ferromagnetic ground states appear. The rigorous method we use is based on the transformation of original hamiltonian into positive semidefinite form. This technique is independent of the spatial dimension and does not require integrability of the model. The obtained ferromagnetism is connected to dispersionless bands but in a much broader sense than flat-band ferromagnetism requires, where on every site a Hubbard term is present. In our case, only a small percentage of, even randomly distributed, sites are only interacting. 相似文献

An effective Hamiltonian for the two-band Hubbard model was derived by a canonical transformation which was calculated and summed up to infinite order . The transformed Hamiltonian contains terms with strongly renormalized interaction energies. These new interaction energies show sign reversals as a function of the hopping integral in addition to a strong reduction in the charge-transfer gap and a significant increase in the attractive oxygen Hubbard term. 相似文献

A new approach to the surface photovoltage method is demonstrated on thick undoped microcrystalline silicon films grown on different substrates. The model, which includes top as well as bottom space-charge regions, gives a good picture of rather complex experiments and allows good fitting of theoretical curves to experimental results. This method gives us not only the diffusion length of minority carriers but also information on the existence and properties of the space-charge regions in the sample and the results are verified by comparison with the standard procedure. 相似文献

We report an experimental determination of trapping efficiency of optical fields acting on spherical particles diluted in viscous fluids. This parameter was derived from experimentally calculated trap stiffness for micron-sized silica beads with particle radii of 1.5 and 4.8 microns, respectively. In order to obtain the trap stiffness, we used the equipartition theorem, and introduced an experimental procedure to calibrate the optical tweezers set-up. The method consists of the calculation of the trapping efficiency by using the curves of the trap stiffness vs. the incident power. Using this approach we measured the efficiency for different values of displacements of the beads in the optical trap, and compared these results with numerical and theoretical calculations reported in the literature, and an excellent agreement was found. We have shown that the ratio of efficiencies is very close to the ratio of the particle radii. 相似文献

People differ in their reactions to the outcomes of their group. Whereas some may revel in victory and mourn in defeat, others may internalize victory but distance themselves from defeat. Here, we sought to relate these divergent reactions to two forms of alignment with groups–identity fusion and group identification. Investigations of the 2008 elections in the United States and Spain revealed that people who were “fused” with their political party internalized both victory and defeat, but highly identified persons internalized only victory. We discuss how these findings bear on the conceptual distinctions between identity fusion and group identification. 相似文献

ResumenCon objeto de comprobar si, como el modelo de Wagner (1976, 1978) postula, durante la habituación a largo plazo se establece una asociación entre el estímulo habituador y las claves ambientales, se llevaron a cabo dos experimentos en humanos. En el experimento I el cambio de contexto ambiental produjo una rehabituación más rápida y una tendencia a una menor recuperación de la respuesta en la segunda situación (empleando un tono de 105 dbs., comienzo súbito y veinticuatro horas de intervalo entre sesiones). En el experimento II (empleando un tono de 80 dbs., comienzo gradual y cuarenta y ocho horas de intervalo entre sesiones), el cambio de contexto ambiental produjo una menor recuperatión de la respuesta y una tendencia a una mayor tasa de habituación. Las instrucciones «informativas» no produjeron habituación diferente de las «normales». Se consideran estos resultados como acordes con una interpretación atencional tradicional de la habituación más que con el modelo de Wagner. 相似文献
