Structural social support: impact on adult substance use and recovery attempts

This study examined the structural social support of 132 men residing in a network of self-run, substance abuse recovery homes. The impact of different types of social relationships on individuals' substance use patterns and recovery attempts was investigated. Results suggest that varying relationship types (i.e., parents, significant other, friends, children, coworkers) have significantly different influences on use and recovery. Additionally, each type of relationship had differential impacts on use versus recovery. Children were the sole relationship type that affected both substance use and recovery attempts in a positive nature, suggesting that children may have a beneficial impact on reducing.     

Economic costs of Oxford House inpatient treatment and incarceration: a preliminary report

The Oxford House model for substance abuse recovery has potential economic advantages associated with the low cost of opening up and maintaining the settings. In the present study, annual program costs per person were estimated for Oxford House based on federal loan information and data collected from Oxford House Inc. In addition, annual treatment and incarceration costs were approximated based on participant data prior to Oxford House residence in conjunction with normative costs for these settings. Societal costs associated with the Oxford House program were relatively low, whereas estimated costs associated with inpatient and incarceration history were high. The implications of these findings are discussed.     

The Effects of Attribution of Responsibility and Work History on Perceptions of Reasonable Accommodations

Under the Americans with Disabilities Act (ADA), employers must provide employees with disabilities reasonable accommodations that will enable them to perform job duties, as long as the accommodations do not financially burden the organization. Two studies were conducted to investigate whether disability origin and/or prior work history impermissibly influence the granting of reasonable accommodations under the ADA. In both studies, participants granted more accommodations for employees whose disability was caused by some external factor than for those whose disability was caused by the employee's own behavior. In Study Two, participants also granted more and costlier accommodations for an employee with an excellent work history than for an employee with an average work history. Implications of the use of extralegal factors in accommodation decisions are discussed.     

Results from the NIST 2004 DNA Quantitation Study

For optimal DNA short tandem repeat (STR) typing results, the DNA concentration ([DNA]) of the sample must be accurately determined prior to the polymerase chain reaction (PCR) amplification step in the typing process. In early 2004, the National Institute of Standards and Technology (NIST) conducted an interlaboratory study to help assess the accuracy of DNA quantitation in forensic DNA laboratories. This study was designed with four primary purposes: (1) to examine concentration effects and to probe performance at the lower DNA concentration levels that are frequently seen in forensic casework; (2) to examine consistency with various methodologies across multiple laboratories; (3) to examine single versus multiple source samples; and (4) to study DNA stability over time and through shipping in two types of storage tubes. Eight DNA samples of [DNA] from 0.05 ng/microL to 1.5 ng/microL were distributed. A total of 287 independent data sets were returned from 80 participants. Results were reported for 19 different DNA quantitation methodologies. Approximately 65% of the data were obtained using traditional slot blot hybridization methods; 21% were obtained using newly available quantitative real-time PCR (Q-PCR) techniques. Information from this interlaboratory study is guiding development of a future NIST Standard Reference Material for Human DNA Quantitation, SRM 2372.     

Chromosomal duplications along the Y-chromosome and their potential impact on Y-STR interpretation

Y-chromosome short tandem repeat (Y-STR) markers are being used as potential tools for distinguishing low levels of male DNA in the presence of excess female DNA as is present in many sexual assault samples. Usually single copy Y-STR loci produce a single amplicon in single source samples, and thus the observation of multiple peaks at such a locus could suggest to an analyst that a mixture of more than one male contributor is present in the tested sample. However, many regions of the Y-chromosome are duplicated or even triplicated in some individuals and this fact can thus complicate potential mixture interpretation. Reasons for the presence of duplications at multiple loci within a single sample are explored in the context of Y-STR marker location along the chromosome. True male-male mixtures commonly exhibit more than one locus-specific PCR product across multiple Y-STR loci that are not adjacent to one another on the Y-chromosome. In addition, duplicated loci typically possess alleles that differ by only a single repeat unit and possess similar peak heights.     

Interpersonal problem-solving skills in battered,counseling, and control women

The present study was designed to examine the interpersonal problem-solving skills of battered women, while controlling for the effects of depression and anxiety. Battered, Counseling, and Control women were administered an interpersonal problem-solving inventory and asked to generate as many behavioral options as possible for each problem and then to select the one option they would chose to use in the given situation. All options were rated for effectiveness by two “blind” raters. Subjects were also administered the BETA intelligence test, the Beck Depression Inventory, and the State-Trait Anxiety Inventory Form-Y. Analysis of variance found no significant differences between the groups for intelligence, but the Counseling women were significantly more depressed and anxious than the Battered or Control women. Analysis of covariance (using BDI and STAI scores as covariates) found that Battered women: (1) generated fewer total options, (2) generated fewer effective options, and (3) chose fewer effective options for use in the situation than both Counseling and Control women. These findings provide indirect support for a general problem-solving skills deficit in battered women and reinforce the importance of problem-solving skills training for battered women.
