The element and orbital-specific electronic structure of thin films of the organic material N,N'-ethylene-bis(1,1,1-trifluoropentane-2,4-dioneiminato)-copper(II) (designated as Cu-TFAC) has been studied using a combination of synchrotron radiation-excited resonant X-ray emission spectroscopy, X-ray photoelectron spectroscopy, X-ray absorption spectroscopy and density functional theory calculations. Furthermore, resonant X-ray emission at the carbon K-edge was used to measure the density of states for individual C sites in the molecule.

Background: Despite evidence supporting the efficacy of buprenorphine relative to established detoxification agents such as clonidine, little research has examined: 1) how best to implement buprenorphine detoxification in outpatient settings; and 2) whether extending the length of buprenorphine detoxification improves treatment engagement and outcomes.

Objectives: The current study examined the impact on 1) successful detoxification completion; 2) transition to longer-term treatment; and 3) treatment engagement of two different length opioid detoxifications using buprenorphine.

Methods: The study compared data obtained from two consecutive studies of early treatment engagement strategies.

In prior research, Katz et al. found that role induction (RI) improved engagement for substance dependent clients relative to standard outpatient treatment orientation. The current study replicates and extends these findings to an examination of long-term outcomes.

This study examined correlates of high (HCA) and low (LCA) cognitive ability among substance dependent individuals who participated in an ongoing study of early engagement strategies. Participants (55% male; 98% African American), were administered the ASI, Shipley Institute of Living Scale, Beck Hopelessness scale, and TCU Motivation Scales at intake. Analyses were limited to 416 participants whose IQs fell within the upper and lower thirds of the sample.

Retention in outpatient drug-free treatment is poor, with many clients terminating prior to receiving therapeutic benefit. This randomized clinical trial compared the impact on retention and drug use of an individual role induction session conducted at intake with the standard group orientation offered at the clinic. Results of interim analyses indicated that participants assigned to role induction (n = 180) were retained for more days, more likely to attend at least one postorientation session, and more satisfied with the treatment program than were those assigned to standard treatment (n = 87).
