Longitudinal outcomes of an early cohort of Ticket to Work participants

Using 2004-2006 National Beneficiary Survey data matched to Social Security administrative data, we follow a cohort of disability beneficiaries participating in the Ticket to Work (TTW) program for several years to assess changes in their service use, health status, employment, and income. About 20 percent of TTW participants achieved employment at levels that would significantly reduce their disability benefits. Another 40 percent achieved some employment success, but the remaining 40 percent reported no earnings during 2003-2005. Use of TTW support services during 2003-2005 was modest. Many participants experienced significant changes in their health status across survey rounds, which might have affected their ability to actively participate in TTW and to become employed. Many also experienced significant employment and income instability. The findings suggest that employment among TTW participants was associated with reduced poverty.     

Remote spectroscopic identification of bloodstains

Blood detection and identification at crime scenes are crucial for harvesting forensic evidence. Unfortunately, most tests for the identification of blood are destructive and time consuming. We present a fast and nondestructive identification test for blood, using noncontact reflectance spectroscopy. We fitted reflectance spectra of 40 bloodstains and 35 nonbloodstains deposited on white cotton with spectroscopic features of the main compounds of blood. Each bloodstain was measured 30 times to account for aging effects. The outcome of the blood measurements was compared with the reflectance of blood-mimicking stains and various body fluids. We found that discrimination between blood and nonblood deposited on white cotton is possible with a specificity of 100% and a sensitivity of 98%. In conclusion, a goodness of fit between the sample's reflectance and the blood component fit may allow identification of blood at crime scenes by remote spectroscopy.     

Volume Determination of Fresh and Dried Bloodstains by Means of Optical Coherence Tomography

The volume of bloodstains found on crime scenes may help forensic investigators reconstruct the location and kinematics of bloodletting events, as stain size, volume, and impact velocity are related. Optical coherence tomography was used as a method to determine the volume and volume ratio of dried and fresh bloodstains on both glass and irregular surfaces or deposited with an impact velocity. The volume of blood drops deposited on smooth glass surfaces was measured within a deviation of 2%. This deviation increased for droplets on irregular surfaces or deposited with an impact velocity. The volume ratio of dried and fresh bloodstains was equal to 19–28% depending on the individual donor and on the use of an anticoagulant. Optical coherence tomography is a good method to determine the volume of fresh and dried bloodstains in laboratory conditions and allows accurate determination of the dry/fresh ratio.     

Political Thuggery and Democratic Dividends in Nigeria

This study focuses on political thuggery and democratic dividends in Nigeria. Utilizing secondary and personal observation data the authors sought to address the following concerns: meaning of political thuggery and democratic dividend, manifestation and spate of political thuggery, and causes and effect of political thuggery and democratic performance since 1999 to date. The study reveals that poverty, unemployment, financial attractiveness of elective positions, the value system of wealth accumulation, and an ineffective security agency account for the incidence of political thuggery in Nigeria. Political thuggery hinders public accountability of elective officers and thus is a bane to good governance in Nigeria. Itg also increases the crime rate and the emergence of credible candidates in elections and thus is a threat to the achievement of democratic dividends and exercise of citizenship rights in Nigeria. On the basis of these findings, the study recommends that government should make elective offices less attractive financially and conceited government programs and policies should be aimed at alleviating unemployment and poverty and strengthening the capacity of security agencies. Government must consistently educate citizens and youth on the evil of political thuggery and violence.     

Personality and repeated suicide attempts in dependent adolescents and young adults

This study compared personality characteristics of subjects with dependence disorders who had previously made a suicide attempt. The population, recruited in France, Belgium, and Switzerland, was composed of 570 subjects (225 females, 345 males, mean age = 27.3, SD = 8.5). The subjects' psychological dimensions were investigated by means of several self-report questionnaires including: BDI-13 (Beck), Sensation-Seeking Scale (Zuckerman), Toronto Alexithymia Scale (Taylor), Interpersonal Dependency Inventory (Hirschfeld), MMPI-2, and some additional scales. For most dimensions, repeat attempters, both past and recent, but more specifically the recent repeaters, had a more severe psychological profile compared to the other suicide attempters.     

Apport de l'immunoelectrophorese pour l'expertise des taches de sang en medecine legale

Conclusive evidence was obtained in this study that immunoelectrophoresis could be used in the identification of blood-stains in two particular cases: for diagnosis or approach to diagnosis of the age of a blood-stain, and for diagnosis of the human origin of a blood-stain that had been treated with petroleum products.Although many aspects should be investigated in more detail, it is certain that this method can be employed in combination with other methods.
