How well do firms in the United States maintain compliance with occupational safety and health administration (OSHA) standards after being cited for a violation? How and why does this vary among standards? This paper identifies serious violations of 91 frequently cited standards at manufacturing plants during 1992–2002 and tracks compliance with that standard in later inspections over 10 years. While formal measures of Repeat violations are quite low, we find considerably higher re-violation rates for some standards once we look separately at how often health standards are cited in later health inspections and safety standards cited in later safety inspections. Characteristics of the standards affect re-violation rates, but not always in the expected direction. Standards whose violations are rated as more hazardous or which received higher initial penalties tend to have more re-violations. These findings could reflect inspector behavior, with those standards getting more attention and thus being cited more frequently. When, as in the case of OSHA and other enforcement agencies, we know about violations only when inspectors cite them, we need to consider bureaucratic behavior as well as employers' incentives.  相似文献

To understand how time and temperature could affect latent fingerprints, wooden pallets were used to construct five units that each housed ten 60-watt incandescent light bulbs. Fingerprints were deposited on the top, middle, and base of the globes. The bulbs were powered on (except the control bulb in each unit) for 18, 48, 72, 120, 168, 336, 504, and 672 h. Fingerprints recovered from the bulbs by tape lift after black powder processing were given a quality score. A thermal imaging camera determined temperatures on three areas of the bulbs. Fingerprints on the top of the globe (156.3°C) had the lowest quality score, and fingerprints on the middle of the globe (112.6°C) had the highest quality score. The mean quality scores of the three temperature classes were within one standard deviation of one another, meaning there is no way to estimate fingerprint age based on its quality after heat exposure.  相似文献

Little is known about the associations between various types of childhood maltreatment and multiple forms of intimate partner violence victimization in early adulthood. This study examines the extent to which childhood experiences of maltreatment increase the risk for intimate partner violence victimization in early adulthood. Data for the present study are from 3322 young adults (55?% female) of the Mater Hospital-University of Queensland Study of Pregnancy with the mean age of 20.6 years. The Mater Hospital-University of Queensland Study of Pregnancy is a prospective Australian pre-birth cohort study of mothers consecutively recruited during their first antenatal clinic visit at Brisbane’s Mater Hospital from 1981 through to 1983. Participants completed the Composite Abuse Scale at 21-year follow-up and linked this dataset to agency recorded substantiated cases of childhood maltreatment. In adjusted models, the odds of reporting emotional intimate partner violence victimization were 1.84, 2.64 and 3.19 times higher in physically abused, neglected and emotionally abused children, respectively. Similarly, the odds of physical intimate partner violence victimization were 1.76, 2.31, 2.74 and 2.76 times higher in those children who had experienced physical abuse, sexual abuse, neglect and emotional abuse, respectively. Harassment was 1.63 times higher in emotionally abused children. The odds of severe combined abuse were 3.97 and 4.62 times greater for emotionally abused and neglected children, respectively. The strongest associations involved reports of child emotional abuse and neglect and multiple forms of intimate partner violence victimization in young adulthood. Childhood maltreatment is a chronic adversity that is associated with specific and multiple forms of intimate partner violence victimization in adulthood.  相似文献

As DNA technology becomes increasingly sensitive, forensic laboratories are receiving more low-template DNA samples. These samples, already low in DNA content, become even more challenging to process as the available DNA becomes further reduced during the extraction step. In this study, two extraction modifications were tested to determine if the cause of DNA loss could be identified and mitigated. A double lysis technique was used to test for DNA loss in the sample collection substrate, and lysate eluates were re-extracted to determine DNA loss from inefficient binding to the silica column. Both modifications showed DNA was lost at these steps. However, resulting STR profiles from these samples had fewer peaks and lower peak heights when compared to samples processed with no extraction modifications. Overall, the potential benefits of adding these extraction modifications for low-template DNA sample processing are not enough to justify the risk associated with additional manipulation.  相似文献

Abstract

“Apocalypse Now” is Francis Ford Coppola's Vietnam in more ways than he understands. It isn't just a matter of the way the film's cost escalated to an astonishing $30 million, nor even the fact that the director didn't know how to end it. The movie is Coppola's Vietnam because it faithfully recapitulates the war in a much more basic way: it is filled with lies, megalomania, self-deception, high moral intent and real moral failure.  相似文献

ABSTRACT

This article addresses two contemporary challenges for the 1980 Hague Child Abduction Convention: (i) domestic violence and (ii) child participation. It also outlines three components of a global socio-legal policy and research initiative undertaken to address these issues and, where relevant, their intersection. The published literature on these topics, including the children’s objections exception, is explored, as are the ways in which these challenges are addressed within some of the 101 Contracting States to the Convention and through the Guide to Good Practice on Article 13(1)(b) of the Convention. Regard is paid to the data provided by the statistical analysis of applications made under the Convention in 2015 by Lowe and Stephens, and the changes which will occur once the Recast of The European Brussels 11a Regulation comes into operation. The likely impact for 1980 Hague Convention abduction proceedings of the UK having left the European Union at 23.00 GMT on 31 January 2020 is contemplated. Other current international initiatives are discussed, including the development of a child-friendly version of the Convention through The International Association of Child Law Researchers. Training is a key to changing attitudes and upskilling family justice professionals to ensure the Convention operates in a fully child-centric way. This will maintain and strengthen the Convention by keeping it ‘fit for purpose’.  相似文献

Posttraumatic stress disorder (PTSD) criteria in DSM-5 included a dissociative diagnostic subtype characterized by a depersonalization item and a derealization item. Researchers have queried whether this was too restrictive, as alternative dissociative symptomatology may also be characteristic of the subtype. The current study utilized data from 318 Northern Irish students, of which 165 were trauma exposed. Participants were assessed for PTSD symptomatology based on DSM-5 criteria via a modified version of the PTSD Symptom Scale-Self-Report (PSS-5) and dissociative experiences via the Dissociative Experiences Scale (DES). Confirmatory factor analysis of PTSD and DES models revealed an optimal four-factor DSM-5 PTSD model including reexperiencing, avoidance, negative alterations in mood and cognitions, and alterations in hyperarousal and reactivity factors, and an optimal three-factor DES model including absorption, amnesia, and depersonalization/derealization factors. When comparing the correlations between depersonalization/derealization and the four PTSD factors, significant Wald tests of parameter constraints revealed that depersonalization/derealization is more related to alterations in arousal and reactivity (r?=?.432) compared to avoidance (r?=?.289), χ 2 (1, N?=?165)?=?8.352, p?=?.004. We discuss whether the mechanism for comorbid PTSD and dissociation may be related to PTSD’s arousal factor.  相似文献
