ABSTRACT
Effective evidence-based intervention for traumatic bereavement is one of the current major research issues in the field of Post Traumatic Stress Disorder (PTSD) in children and adolescents. The "Writing for Recovery" group intervention is a new treatment approach developed by the Children and War Foundation for traumatized and bereaved children and adolescents after disasters. The purpose of this project was an empirical examination of this intervention with 12- to 18-year-old war bereaved Afghani refugees. Eighty-eight war bereaved Afghani refugees were screened using the Traumatic Grief Inventory for Children (TGIC). From those with the highest total score, 61 were randomly assigned to either an experimental (n = 29) or control group (n = 32). The experimental group received six sessions of group training on 3 consecutive days in their school. The difference of TGIC scores between the experimental group in pretest and posttest was significant (p = 0.001). Results of analysis of covariance also showed a significant effect of Writing for Recovery on the experimental group (p < 0.001). It is concluded that "Writing for Recovery" is an effective group intervention for bereaved children and adolescents after disasters.

Mesoporous aluminosilicates, have been prepared with various mole ratios of Si/Al and Cethyltrimethylammonium bromide (CTAB). They have been characterized by XRD, nitrogen adsorption/desorption measurements, FT-IR and thermogravimetry. Adsorption behavior of heavy metal ions on this adsorbent have been studied and discussed. The results show that incorporation of aluminum ions in the framework of the mesoporous MCM-41 has transformed it into an effective cation exchanger. The K(d) values of several metal ions have been increased. Separation of Sr(II)-Ce(III), Sr(II)-U(VI) and Cd(II)-Ce(III) has been developed on columns of this novel mesoporous cation exchanger.

A new mixed metal heteropoly anion-based cation exchanger Zr(IV) molybdo tungsto vanado silicate (ZMTVS) was prepared under varying conditions. The material was characterized by FTIR, X-ray diffraction, TGA-DTA and SEM techniques. Its ion exchange capacity (IEC) for K(+) was found to be 0.86 meq g(-1). Distribution coefficients (K(d)) values for 10 metal ions and three radioisotopes were determined. On the basis of K(d) values, two important and analytically difficult quantitative binary separations viz. Ni(II)-Co(II) and Ni(II)-Pb(II) were achieved on its column. Decontamination of aqueous nuclear waste solution was also studied.

A novel polyoxometalate-cation exchanger, titanium(IV) molybdophosphate (TMP) has been synthesized under varying conditions. The material was characterized by X-ray diffraction, infrared spectroscopy, inductively coupled plasma and thermogravimetry techniques. Its stability was investigated in water, dilute acids, alkaline solutions, and high temperature up to 750 degrees C. Ion-exchange capacity and distribution coefficients (K(d)) for twenty-nine radionuclides and metal ions have been determined. It was found that the TMP has high affinity for Cs(+), Sr(2+), UO(2)(2+), Ba(2+), Pb(2+), Tl(+), Zn(2+), Rb(2+) and Zr(4+) ions. The results of binary separation of metal ions showed that TMP can be potentially useful for analytical applications.
