The goal of the Healthy Families America Research to Practice Network (RPN) was to foster communication among academic researchers, community-based evaluators, and practitioners to integrate science-based prevention practices into practice settings. The RPN goals were guided by and are a response to the limitations of past and current research paradigms in the social sciences. Accomplishments included creation of a 40-member researcher-practitioner council, development of a national Program Information Management System, and completion of a 4-year national Implementation Study, employing data from over 100 sites in nine states. The discussion examines what was learned about this rare experiment in creating practitioner-scientist partnerships and the impact of the RPN on child abuse and neglect prevention. A five-year plan to sustain and strengthen a practice-research collaborative is recommended. 相似文献

Little research has investigated the prevalence of mood disturbance among sex offenders despite the fact that psychological
distress may bear some relationship to community reintegration, and ultimately, recidivism. All offenders on New Jersey’s
sex offender Internet registry were mailed surveys about their experiences with, and perceptions of, notification and residence
restriction statutes, the Beck Depression Inventory-II (BDI-II), and the Beck Hopelessness Scale (BHS). On average, respondents
(N = 104) reported mild to moderate levels of depressive symptoms (M
BDI = 17.1) and hopelessness (M
BHS = 6.9). Additionally, offenders who reported being negatively affected by residence restrictions and notification statutes
reported higher levels of both depression and hopelessness. Given evidence that sex offender specific legislation may de-stabilize
offenders, this research highlights the importance of managing affective states in this population. 相似文献

In some circumstances, the presence of adipocere may retard decomposition and complicate postmortem interval estimation. This article explores the correlation between Accumulated Degree Days (ADD) and early stage formation of adipocere. Sixty wild rabbit (Oryctolagus cuniculus) carcasses were used in this experiment; a control group (N = 30) deposited directly on the ground surface and an experimental group (N = 30) completely submersed in water in individual buckets. Data (water and inner body temperature, pH, and total body score) were collected every 100 ADD. Results indicated that early stage adipocere is correlated to ADD and that its formation on submersed remains is more likely to occur after 630 ADD. Skin sloughing promoted the formation of adipocere. No adipocere was formed on any of the control group rabbits. This study also highlights the fact that multiple factors influence adipocere formation and it is suggested that further research needs to be conducted into this area. 相似文献

Although researchers have examined many aspects of fire modification, the rate and pattern of decomposition in charred remains have not been studied previously. This study utilized 48 domestic pigs, divided into 24 charred (head, neck, and limbs burned to Crow-Glassman level 1 and torso to level 2) and 24 un-charred pig carcasses. Decomposition of control carcasses was scored at 50 accumulated degree days (ADD) intervals, and charred carcasses were also observed and photographed at this time. A Charred Body Scale was subsequently created, and charred carcasses were scored retrospectively for the same ADD intervals. Analysis using a mixed-effect repeated measures model indicated that, while decomposition rate was not statistically different between the two groups (p = 0.2692), the charred remains initially displayed an ostensibly more advanced pattern. Body regions displaying significant charring decomposed at a faster rate (p < 0.001), while areas with very light levels of charring decomposed at a significantly slower rate (p < 0.001). 相似文献

This study presents the prevalence of ethanol and illicit drugs in fatal road traffic accident victims in the Centre of Portugal between January 1990 and December 2007. Among the violent deaths, road traffic accidents presented the highest percentage (around 35%; n=3095), but decreasing throughout the years. Accidents were preponderant in males (about 80%; n=2402), between 21 and 30 years-old. Accidents involving drivers (55%; n=1310) were of the most common, being the car the main vehicle (45%), followed by the motorcycle (40%). An alcohol analysis request was present in 50% of the cases (n=1687), but increasing each year. Ethanol concentrations >1.2g/L, the legal limit in Portugal, were found in 55% (n=283) of the cases. Concerning drugs of abuse requests, only 4.4% (n=137) and 17.3% (58 cases) of the cases included the analysis at the Forensic Pathology Department (FPD) and at the Medico-Legal Office (MLO), respectively. Among the road accident cases analysed, 18 were positive, mainly in men (84%), between 21 and 30 years-old; opiates (47.1%; n=8) and cannabinoids (50%; n=4) were the most found, at the FPD and at the MLO, respectively. In conclusion, ethanol was identified as a key factor to traffic accidents, which explains the definition of specific legislation and methods of enforcement to prohibit this form of impairing. Nevertheless, ethanol still remains the psychoactive substance most frequently identified in the blood of divers killed in road-traffic crashes, recommending additional actions of supervision and control. 相似文献

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive. This case report describes a 1‐month, 27‐day‐old male infant with a diagnosis of X‐linked recessive anhidrotic ectodermal dysplasia. On the day of his death, his mother swaddled him in a blanket and placed him on the couch at 5:30 am. When she picked him up at 8:00 am, he was unresponsive. At the emergency department, his rectal temperature was 40°C. Postmortem blood culture was positive for group B streptococcus, a possible etiology for fever. It is vital to teach parents that close monitoring of children with ectodermal dysplasia is necessary, as an increase in body temperature can become life threatening. 相似文献

Five pairs of mass graves, each containing carcasses of 21 rabbits, were used to examine differential decomposition at four locations within the burial: surface, deep, mid‐outer, and core. Every 100 accumulated degree days (ADD), a pair of graves was exhumed, and total body score (TBS) and internal carcass temperature of each rabbit were recorded. Decomposition did not differ for core‐ and deep‐positioned carcasses (p = 0.13); differences were significant (p < 0.001) for all other location comparisons. Decomposition occurred fastest in shallow carcasses, followed by mid‐outer carcasses; deep and core carcasses decomposed slowest and at rates not significantly different from one another. Adipocere formation was minimal and confined to deep carcasses. Carcass location within the mass grave significantly influenced internal carcass temperature (p < 0.001); a mean internal temperature difference of ca. 1°C existed between deep and shallow carcasses (30 cm apart). Effects of mass compactness and oxygenation require further investigation. 相似文献

The occurrence of secondary DNA transfer has been previously established. However, the transfer of DNA through an intermediary has not been revisited with more sensitive current technologies implemented to increase the likelihood of obtaining results from low‐template/low‐quality samples. This study evaluated whether this increased sensitivity could lead to the detection of interpretable secondary DNA transfer profiles. After two minutes of hand to hand contact, participants immediately handled assigned knives. Swabbings of the knives with detectable amounts of DNA were amplified with the Identifiler® Plus Amplification Kit and injected on a 3130xl. DNA typing results indicated that secondary DNA transfer was detected in 85% of the samples. In five samples, the secondary contributor was either the only contributor or the major contributor identified despite never coming into direct contact with the knife. This study demonstrates the risk of assuming that DNA recovered from an object resulted from direct contact. 相似文献

Intimate partner violence (IPV) is a prevalent problem associated with multiple negative outcomes for survivors’ well-being. Coping has emerged as an important construct in understanding the association between IPV and survivors’ well-being. Research is needed to better understand the contextual complexity of IPV as a stressor, determine if IPV is a unique stressor, and document survivors’ coping experiences. This article reports findings of a qualitative study with 25 female survivors and 6 service providers. Analysis of interview data shows 3 key themes: (a) coping strategies used by survivors; (b) challenges and barriers to coping with IPV; and (c) IPV as a unique stressor. Despite multiple challenges and barriers to coping with IPV, survivors use multiple, varied strategies to cope with their experiences of abuse. However, given the context and nature of IPV, violent victimization is a distinct stressor with unique barriers that often require IPV-specific coping strategies. 相似文献
