Do Employers Prefer Workers Who Attend For‐Profit Colleges? Evidence from a Field Experiment 下载免费PDF全文
Rajeev Darolia Cory Koedel Paco Martorell Katie Wilson Francisco Perez‐Arce 《Journal of policy analysis and management》2015,34(4):881-903
This paper reports results from a resume‐based field experiment designed to examine employer preferences for job applicants who attended for‐profit colleges. For‐profit colleges have seen sharp increases in enrollment in recent years despite alternatives, such as public community colleges, being much cheaper. We sent almost 9,000 fictitious resumes of young job applicants who recently completed their schooling to online job postings in six occupational categories and tracked employer callback rates. We find no evidence that employers prefer applicants with resumes listing a for‐profit college relative to those whose resumes list either a community college or no college at all. 相似文献

What Happened to the Women? Gender and Reparations for Human Rights Violations, ed. Ruth Rubio-Marin
What Happened to the Women? Gender and Reparations for HumanRights Violations, edited by Ruth Rubio-Marin, represents asignificant contribution to the literature on transitional justice.Most writings regarding the aftermath of widespread human rightsviolations focus on prosecutions and truth-telling. Relativelyfew works discuss reparations. Fewer still explore what reparations,if any, are specific to female 相似文献

Fired cartridge cases are a common type of evidence found at crime scenes. However, due to the high chamber temperatures and touch nature of this evidence, DNA testing is not commonly sought because it is believed DNA is only present in low levels, whether it is due to initial low levels of DNA and/or DNA degradation from the heat or inhibition of the PCR reaction. Moreover, very few laboratories report STR typing success with fired cases. This study focused on obtaining STR profiles from fired cartridge cases using the AmpFℓSTR® MiniFiler™ kit, which is designed to amplify DNA from low level, inhibited, and degraded samples. Comparisons to other STR amplification kits were also conducted. In attempt to simulate casework, random individuals loaded cartridges into a firearm. DNA was recovered from the fired cartridge cases using the double swab technique and extracted using an automated large volume DNA IQ™ method. Initially, testing focused on known shedders handling cartridges for 30 s prior to firing. A significantly greater number of alleles was obtained following amplification with the MiniFiler™ kit versus the PowerPlex® 16 BIO kit. No alleles were observed using the Identifiler® kit. In an attempt to better simulate casework, a random selection of laboratory personnel handled shotshells for as long as needed to load and fire the weapon. In this mock sample study, the MiniFiler™ kit successfully amplified an average of 22% of expected alleles from DNA recovered from shotshell cases versus the PowerPlex® 16 BIO kit where an average of 7% of alleles were observed. However, the total number of alleles obtained from the two kits was not significantly different. The quality of the DNA obtained from fired cases was studied with evidence of inhibition in at least 11% of shotshell case samples. After swabbing the head and the hull of three shotshell cases separately, a significantly greater number of alleles was obtained from the hull as opposed to the head of the fired shotshell case. In addition, after firing, various internal firearm surfaces were swabbed, including the chamber of barrel, ejection port, and breechface, in an attempt to obtain amplifiable DNA. DNA was obtained from the chamber of the barrel and was amplifiable using the MiniFiler™ kit, although mixtures were obtained with extensive drop-in and drop-out making this analysis unlikely to aid an investigation. 相似文献

Because romantic partners frequently disagree on the violence in their relationship, relying on nondyadic data for perpetration and victimization rates, especially to inform the gender symmetry controversy, is problematic. In order to have a more nuanced understanding of gender symmetry, we urge researchers to be cautious when drawing symmetry conclusions from non-dyadic samples. Furthermore, using both partners, we suggest that researchers employ more qualitative approaches to ascertain IPV agreement, note times in which either partner reports IPV as an indicator of the presence of violence, and investigate the extent to which conclusions regarding gender symmetry stem from participant selection bias. 相似文献
