This study aimed to implement and evaluate a work-based personal resilience enhancement intervention for forensic nurses. A mixed methods design consisting of surveys, interviews, and a case study approach, whereby the experiences of a group of nurses were studied in relation to their experiences of an intervention programme to enhance personal resilience, was utilized. Nurses working on forensic inpatient wards were invited to participate. Senior nurses were recruited as mentors. Data were collected via pre- and post-programme surveys to evaluate nurses' levels of resilience. Post-programme interviews were undertaken with nurses and mentors to explore their experiences of the programme. Descriptive statistics of survey data examined changes in nurses' resilience levels pre- and post-intervention. Free-text survey data and interview data were analysed thematically. The SQUIRE 2.0 checklist was adhered to. Twenty-nine nurses participated. Levels of personal resilience (M = 4.12, SD = 0.60) were significantly higher post-programme than pre-programme (M = 3.42, SD = 0.70), (t49 = 3.80, P = 0.000, 95% CI = 0.32, 1.07). Nurses felt the programme had a marked impact on their personal resilience, self-awareness, confidence, and professional relationships. The benefits of the programme demonstrate the advantages of providing a nurturing environment for nurses to consolidate their resilience levels. Findings demonstrated that resilience enhancement programmes can increase nurses' levels of resilience and confidence and improve inter-professional relationships. Our findings are important for clinicians, nurse managers, and policymakers considering strategies for improving the workplace environment for nurses. The long-term impact of resilience programmes may improve nurse retention and recruitment.
In fiscal year 2020, all state and local forensic capacity enhancement programs previously administered by NIJ, including most of the programs listed on this page, moved to the Bureau of Justice Assistance (BJA).
We are dedicated to improving the understanding of crime and justice issues through science. Since 2004, NIJ has received annual appropriations for the purposes of various DNA and other forensic science activities. These purposes include support for DNA analysis and laboratory capacity enhancement and support for the forensic science research, development and evaluation that provides knowledge and tools to improve the quality and practice of forensic science and therefore reduce crime and improve public safety.
Each year we consider how to allocate DNA and other forensic activity funds based on needs such as the demand to increase capacity and reduce DNA backlog, NIJ technology working group recommendations, results from studies and new findings, and strategic priorities and perspectives for each of the programs.
NIJ remains a leader within Federal government for forensic science research and development and the Bureau of Justice Assistance will take over administration of all forensic capacity enhancement programs.
We want to assure organizations who rely on these grant programs to support forensics that staff from BJA and NIJ are working closely with one another to ensure a smooth transition. That includes making sure solicitations are posted and grants are made.
The Department of Geography and Anthropology has been offering forensic anthropology services since the late 1970's, with a formal lab being established in the Howe-Russell Geosciences Complex East in the 1990's. Our founder, Mary Manhein, established the FACES Lab in cooperation with Louisiana State University and the State of Louisiana in order to offer expanded services to law enforcement and Coroner's offices.
The FACES Lab offers services such as recovery of remains and assistance in identification, forensic facial reconstruction, DNA collection, inclusion and maintenance of cases in the state repository database, trainings for law enforcement, and so much more.
Did you know that forensic analyses of DNA were being used well before the completion of the Human Genome Project, but newer approaches are speeding up and greatly improving the process, and larger DNA databases are making searches more powerful and more widely available? The National DNA Index in the United States now contains information from over 16 million people and has been used to aid in over 387,000 investigations.
As new, more powerful technologies for amplifying and sequencing tiny amounts of DNA became available [see DNA Sequencing], scientists teamed up with law enforcement officials to improve the use of DNA analyses for crime solving. In the United States, the Federal Bureau of Investigation created the Combined DNA Index System (CODIS) in 1990. Today, a CODIS forensic profile combines information from analyzing 20 different STRs across the human genome. In theory, the combined data generated for this panel is specific enough to identify one person on earth.
In practice, gathering samples and accurately analyzing the DNA can be problematic. We leave our own DNA behind us all the time, through stray hairs, skin cells, or other materials. This means that samples collected from a crime scene might be a mix of multiple people, and could potentially lead to the real perpetrator of a crime to not be identified. Or, in cases of mass casualties or environmental disasters, many samples might be mixed together or subjected to high pressure, moisture, or temperature. Advances in genomic technologies, including DNA sequencing, are allowing for more precise identification, in some cases using DNA samples collected years ago. For instance, forensic scientists are still working to use DNA analyses for identifying remains from the World Trade Center site after September 11, 2001 and soldiers from the Vietnam war.
DNA forensic analyses are only as good as the people performing the tests. In some cases, samples might get mixed up in the laboratory or statistical calculations may lead to erroneous conclusions. Groups like The Innocence Project use DNA analyses to exonerate people accused of crimes by showing years later that their DNA does not match the sample(s) collected years earlier at the scene.
As we improve our ability to analyze ancient DNA samples [see Human Origins and Ancestry] and to understand how our genomes encode our traits, we are gaining interesting insights about what humans looked like in the past and now. Recently, genomic analyses of a set of 10,000-year-old human remains in the United Kingdom (called "Cheddar Man" because he was found in the Cheddar Gorge), allowed scientists to predict what some of the first Britons might have looked like. According to the researchers, Cheddar Man and his relatives would have likely had dark skin, dark hair and light eyes. More recently, scientists have been working towards developing a "police sketch" based on analyses of DNA collected at a crime scene. While DNA variation cannot yet predict an exact facial appearance of a person, it can suggest some traits that can be useful for investigating a crime, like hair color and eye color. The limits of this technology have been explored in an art installation where DNA from discarded chewing gum and cigarette butts was analyzed and used to create sculptures of what the person might have looked like. While still highly speculative, forensic scientists may be able to add such an approach to their toolkit along with other lines of evidence for deducing some elements of a suspect's physical appearance.
