Children’s episodic and generic reports of alleged abuse

With the present data, we explored the relations between the language of interviewer questions, children’s reports, and case and child characteristics in forensic interviews. Results clearly indicated that the type of questions posed by interviewers – either probing generic or episodic features of an event – was related to the specificity of information reported by children. Further, interviewers appeared to adjust their questioning strategies based on the frequency of the alleged abuse. Children alleging single instances of abuse were asked more episodic questions than those alleging multiple abuses. In contrast, children alleging multiple incidents of abuse were asked a greater proportion of generic questions. Given that investigators often seek forensically-relevant episodic information, it is recommended that training for investigators focus on recognition of prompt selection tendencies and developing strategies for posing non-suggestive, episodically focused questions

Electronic modulation of infrared emissivity in graphene plasmonic resonators

Electronic control of blackbody emission from graphene plasmonic resonators on a silicon nitride substrate is demonstrated at temperatures up to 250 C. It is shown that the graphene resonators produce antenna-coupled blackbody radiation, manifest as narrow spectral emission peaks in the mid-IR. By continuously varying the nanoresonators carrier density, the frequency and intensity of these spectral features can be modulated via an electrostatic gate. We describe these phenomena as plasmonically enhanced radiative emission originating both from loss channels associated with plasmon decay in the graphene sheet and from vibrational modes in the SiNx.Comment: 17 pages, 6 figure

Equations of state and stability of MgSiO3_3 perovskite and post-perovskite phases from quantum Monte Carlo simulations

We have performed quantum Monte Carlo (QMC) simulations and density functional theory (DFT) calculations to study the equations of state of MgSiO$_3$ perovskite (Pv) and post-perovskite (PPv), up to the pressure and temperature conditions of the base of Earth's lower mantle. The ground state energies were derived using QMC and the temperature dependent Helmholtz free energies were calculated within the quasi-harmonic approximation and density functional perturbation theory. The equations of state for both phases of MgSiO$_3$ agree well with experiments, and better than those from generalized gradient approximation (GGA) calculations. The Pv-PPv phase boundary calculated from our QMC equations of states is also consistent with experiments, and better than previous LDA calculations. We discuss the implications for double crossing of the Pv-PPv boundary in the Earth

Developing cultural competence in working with Korean immigrant families

The authors provide an in-depth examination of the historical background, cultural values, family roles, and community contexts of Korean Americans as an aid to both researchers and clinicians in developing cultural competence with this particular group. First, the concept of cultural competence is defined. A brief history of Korean immigration patterns to the United States and demographic information about Korean Americans are reviewed. Second, Korean cultural values, family structure, and family roles are examined as they impact relationships in research and clinical contexts. Three indigenous concepts (cf. L. Kim, 1992) that may be useful in developing cultural competence include haan (suppressed anger), jeong (strong feeling of kinship), and noon-chi (ability to evaluate social situations through implicit cues). Clinical case examples and accounts from a community-based research perspective illustrate these cultural values. Third, important community resources in the Korean American context are highlighted. Links between cultural competence and “ecological pragmatism ” (Kelly, Azelton, Burzette, & Mock, 1994) are discussed. © 2006 Wiley Periodicals, Inc
