Cognitive factors contributing to adolescent depression

The purpose of this study was to investigate cognitive processes, which have been found in depressed adults, that may contribute to depression in adolescents. To this end, a modified version of Kelly's Role Construct Repertory Test was administered to 15 clinically depressed adolescents, 15 somewhat depressed adolescents, and 15 nondepressed adolescents, whose ages ranged from 13 to 16 years with the majority (75%) being female. Compared to the other groups, the clinically depressed group demonstrated lower self-esteem, greater pessimism about the future, more frequent polarized construing, increased interpersonal isolation, and a more external locus of control. Results are discussed in relation to findings from previous studies and recommendations are made for future research.This study is based upon Wayne Hammond's master's thesis, which was supervised by David Romney.Received MSc. from University of Calgary. Doctoral thesis will investigate substance abuse among the native Indians.Received Ph.D. in Clinical Psychology from the Institute of Psychiatry (The Maudsley Hospital) in London, England. Research interests include identity formation in adolescents.

Twelve Y-chromosomal short tandem repeats (STRs), DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS388, DYS426 and DYS439 were typed in Berber-speaking (n=49) and Arabic-speaking (n=60) population samples from Morocco.     

Social Protection Policy or a Political Largesse: Disability Fund Efficacy Assessment and Roadblocks to Sustainable Development Goals

ABSTRACT

Social protection policies have been tools for fighting social exclusion, inequality and reducing poverty incidence among vulnerable populations in developing countries. In this regard, the government of Ghana through the institution of the disability fund has demonstrated a commitment to advancing the cause of people with disabilities. In assessing policy efficacy, the realities on the ground, as well as policy challenges, 130 persons with disability (PWDs) and 10 Key Informants (KIs) were recruited from across five regions. In addition to conducting face-to-face interviews with PWDs, the study conducted a number of interviews with key informants (KIs). The study findings concluded amongst other things that, the policy is plagued with challenges such as limited information about the fund, fund access difficulty and disbursement delays. It was also revealed that; the policy is saddled with opacity and partisan politics. To ensure efficiency and expedite the achievement of Sustainable Development Goal (SDG) 1, the research proposed for policy restructuring. In addition to introducing financial literacy and management training for beneficiaries, the study proffers decoupling the fund management from political structures to help meet the objectives for which it was incepted.     

Specificity,Sensitivity, and Operability of RSID™‐Urine for Forensic Identification of Urine: Comparison with ELISA for Tamm‐Horsfall Protein

Abstract: In this study, the specificity, sensitivity, and operability of RSID?‐Urine, a new immunochromatographic test for urine identification, was evaluated and compared with ELISA detection of Tamm‐Horsfall protein (THP). Urine was successfully identified among other body fluids using RSID?‐Urine and ELISA detection of THP. The detection limit of RSID?‐Urine equated to 0.5 μL of urine; although the sensitivity of RSID?‐Urine may be lower than that of ELISA detection of THP, it is thought to be sufficient for application to casework samples. However, results from RSID?‐Urine must be interpreted with caution when the sample may have been contaminated with blood or vaginal fluid, because this might inhibit urine detection. The RSID?‐Urine assay can be performed in just 15 min by dropping the extracted sample onto the test cassette. Therefore, RSID?‐Urine should be an effective tool for the forensic identification of urine, in addition to ELISA detection of THP.     

Detection of dermcidin for sweat identification by real-time RT-PCR and ELISA

We evaluated the performance of real-time RT-PCR and ELISA assays for detection of dermcidin (DCD) in sweat and body-fluid stains. DCD, a small antibiotic peptide secreted into human sweat, was detected by real-time RT-PCR in 7-day-old stains containing as small as 10 μL of sweat, and the assay showed high specificity when testing 7-day-old stains containing 30 μL of other body-fluid. ELISA using anti-human dermcidin mouse monoclonal antibody detected DCD sweat diluted up to approximately 10,000-fold and could specifically detect DCD in 10 μL of body-fluid stains. The performance of the two assays was tested during winter on samples that simulated forensic case samples: an undershirt and a sock worn for 20 h, a handkerchief used to wipe the brow several times within 12 h, a cap and a cotton glove worn for 4 h, and a white robe worn at intervals for 2 years. The result showed that the former assay detected DCD in all sites of the undershirt examined (armpit, back, and breast), and the latter gave a relatively high OD value in the armpit among the three sites. For the socks, although the latter assay gave very high OD values in both the center and toe of the foot sole, the former could not detect DCD in both of them. These results indicate that highly damp conditions, such as inside a shoe, might promote the degradation of mRNA in samples such as socks. In the other case samples, sweat was adequately detected by both assays.This study is the first demonstration of the use of real-time RT-PCR to sensitively identify sweat among body-fluid stains, and it confirmed that dermcidin was an excellent marker for sweat identification. In addition, the usefulness of ELISA was also verified. Positive sweat identification using these assays is expected to assist forensic practice.
