4th DNA Forensic Symposium: Challenges and future directions in Africa.

The 4th Forensic DNA Symposium in Africa underscored the critical role of regional collaboration in advancing forensic sciences, with a particular focus on forensic DNA examinations, databases, and humanitarian initiatives. The symposium aimed to assess the current forensic DNA capabilities across African countries and develop strategies to expand and better utilize DNA platforms. Key findings from the symposium highlight the necessity for enhanced cooperation among African nations to build robust forensic DNA databases and improve data-sharing mechanisms.

Distinguishing between stamping in blood from walking through blood using blood pattern analysis.

Bloodstains are typically encountered in violent incidents involving the use of a weapon or physical actions, such as punching, kicking, or stamping. Bloodstain pattern analysis can provide inceptive evidence or intelligence about what happened in an alleged incident, the sequence of events, along with indicating possible suspects if blood is analysed through DNA profiling. This research project focused on the differences in patterns created on footwear during a violent action, such as stamping on a person, and a non-violent action, such as walking through a pool of blood.

Developing a virtual laboratory module for forensic science degree programmes.

Laboratory work is essential in forensic science degree courses. They provide students with an opportunity to put theory into practice, as well as develop relevant professional laboratory skills through a case-based learning framework. Traditional laboratory instruction involves the use of a written laboratory script or manual that details the laboratory procedures and techniques for an experiment.

Hydrolysis of Soybean Milk Protein by Papain: Antioxidant, Anti-Angiotensin, Antigenic and Digestibility Perspectives.

The objective of the investigation was to understand the biochemical activities of hydrolysate of soybean milk protein (SMP). Hydrolysis was carried out by different concentrations of papain (0.008 g·L, 0.

Integrity, Trustworthiness, and Effectiveness: Towards an Ethos for Forensic Genetics.

Forensic genetics comes under critical scrutiny when developments challenge previously accepted legal, ethical, social, and other boundaries. Forensic geneticists continue to build a knowledge culture within a community of practice that acknowledges ethical standards of conduct in both research and the societal application of forensic genetics. As the community further cements and extends its societal role, and in that process often pushing at ethical and legal boundaries, it requires a strong, resilient, and responsive ethos that, in setting clear parameters for conduct, fosters the field's sense of purpose.

Forensic science in Ghana: A review.

The use of forensic science continues to grow across the world. In Ghana, major advancements took off in 2011, including the introduction of modern DNA profiling and the establishment of an automated fingerprint identification system. These developments have led to some positive impacts on the delivery of justice, including the exoneration of a wrongly incarcerated individual.

Gaughran vs the UK and public acceptability of forensic biometrics retention.

This commentary provides a response to the European Court of Human Rights ruling in the case of Gaughran vs the United Kingdom on 13 February 2020. The Court ruled that the indefinite retention of DNA, fingerprints and facial images from all convicted adults was disproportionate. Using data from a survey on public attitudes, we examine the public acceptability of the police retention of forensic biometrics from the population.

Towards a reformed policy for immigrant DNA tests, a commentary.

DNA can be useful corroborative evidence in establishing familial relationship in immigration cases. Presently, there is no specific law in the UK regulating the use of DNA in this domain. This has led to inconsistencies in policy guidance and the rejection of some immigrant applications solely or partly due to a lack of DNA evidence.

The effectiveness of the UK national DNA database.

Since the emergence of forensic DNA profiling and the corollary creation of DNA databases, efforts to maximise the efficiency and utility of DNA technology have intensified. Such efforts are expedient given the imperative that expenditure on DNA should be cost-effective and the benefits demonstrable. The practice of retaining DNA profiles in databases, either obtained from individuals involved in criminal investigations, or retrieved from suspected crime scenes, has spread globally.

Trends in forensic DNA database: transnational exchange of DNA data.

The transnational exchange of forensic DNA data has become a modern trend in fighting cross-border crime, terrorism and illegal immigration. Forensic DNA data allow the police to identify, eliminate or link individuals associated with a crime. Additionally, different crime scenes can be linked via the DNA profile to identify serial offenders or determine crime patterns.

Forensic DNA retention: Public perspective studies in the United Kingdom and around the world.

This review analysed public perspective studies on forensic DNA retention in the United Kingdom and around the world. The studies generally show strong public support for the long-term or indefinite retention of DNA from convicts and suspects. There is considerable support for the retention of DNA from all or some arrestees and potentially the entire population.

The long-run effects of economic, demographic, and political indices on actual and potential CO emissions.

This study examines the long-run drivers of potential and actual CO emissions in Ghana, a sub-Saharan Africa country. The use of the former helps address the reverse causality problem and capture the true long-run effects. The Stock-Watson dynamic OLS is used with data from 1970 to 2014.

The UK National DNA Database: Implementation of the Protection of Freedoms Act 2012.

In 2008, the European Court of Human Rights, in S and Marper v the United Kingdom, ruled that a retention regime that permits the indefinite retention of DNA records of both convicted and non-convicted ("innocent") individuals is disproportionate. The court noted that there was inadequate evidence to justify the retention of DNA records of the innocent. Since the Marper ruling, the laws governing the taking, use, and retention of forensic DNA in England and Wales have changed with the enactment of the Protection of Freedoms Act 2012 (PoFA).

Evaluation of Changes in Ghanaian Students' Attitudes Towards Science Following Neuroscience Outreach Activities: A Means to Identify Effective Ways to Inspire Interest in Science Careers.

The scientific capacity in many African countries is low. Ghana, for example, is estimated to have approximately twenty-three researchers per a million inhabitants. In order to improve interest in science among future professionals, appropriate techniques should be developed and employed to identify barriers and correlates of science education among pre-university students.

Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks in 188 countries, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution.

Global, regional, and national incidence and mortality for HIV, tuberculosis, and malaria during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis, and malaria through the formulation of Millennium Development Goal (MDG) 6. The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation for between 1990 and 2013, and an opportunity to assess whether accelerated progress has occured since the Millennium Declaration.

Methods: To estimate incidence and mortality for HIV, we used the UNAIDS Spectrum model appropriately modified based on a systematic review of available studies of mortality with and without antiretroviral therapy (ART).

Global, regional, and national levels and causes of maternal mortality during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: The fifth Millennium Development Goal (MDG 5) established the goal of a 75% reduction in the maternal mortality ratio (MMR; number of maternal deaths per 100,000 livebirths) between 1990 and 2015. We aimed to measure levels and track trends in maternal mortality, the key causes contributing to maternal death, and timing of maternal death with respect to delivery.

Methods: We used robust statistical methods including the Cause of Death Ensemble model (CODEm) to analyse a database of data for 7065 site-years and estimate the number of maternal deaths from all causes in 188 countries between 1990 and 2013.

Global, regional, and national levels of neonatal, infant, and under-5 mortality during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: Remarkable financial and political efforts have been focused on the reduction of child mortality during the past few decades. Timely measurements of levels and trends in under-5 mortality are important to assess progress towards the Millennium Development Goal 4 (MDG 4) target of reduction of child mortality by two thirds from 1990 to 2015, and to identify models of success.

Methods: We generated updated estimates of child mortality in early neonatal (age 0-6 days), late neonatal (7-28 days), postneonatal (29-364 days), childhood (1-4 years), and under-5 (0-4 years) age groups for 188 countries from 1970 to 2013, with more than 29,000 survey, census, vital registration, and sample registration datapoints.

Coronary artery bypass graft for anomalous right coronary artery.

A 27-year-old man with anomalous right coronary artery (RCA) presented with ventricular fibrillatory arrest. Computed tomography angiography revealed an anomalous RCA arising from the left sinus of Valsalva with an acute angulation at the coronary takeoff and compressed interarterial segment. This patient underwent a short saphenous vein coronary artery bypass graft to the proximal RCA and recovered uneventfully.

College females as mothers: balancing the roles of student and motherhood.

As more female college students are involved in sexual relationships their risk of conception increases. However, when pregnancy occurs it is only the woman who bears the burden and risk of the pregnancy and in most cases child care. Female college students who become pregnant are then faced with, not only the risk of the child birth but also the responsibility of their education and childcare.

First-time fathers and stressors in the postpartum period.

The purpose of this pilot study was to examine the everyday stressors of first-time fathers during the postpartum period and to begin the process of establishing reliability and validity for the use of the Everyday Stressors Index with a sample of first-time fathers. A convenience sample of 19 participants included first-time fathers ranging in age from 18 to 45 years and mostly living in medium-sized cities. The results indicated that factors such as a feeling of not having enough time for too many responsibilities, financial issues, and concerns about the health of the child and other family member(s) were sources of stress.

Gaps between HIV/AIDS policies and treatment in correctional facilities.

In this article the authors examined correctional policy and its impact on the incidence of HIV/AIDS in prison population. Using data from the Florida Correctional System, they find that HIV/AIDS is still the leading cause of death. Improved treatment and care may have led to declines in AIDS-related mortality but the prison population continues to experience a much higher risk of mortality than he general population in spite of changes in the treatment and provision of care to infected patients.

Revisiting the debate of voluntary versus mandatory HIV/AIDS testing in U.S. prisons.

Many studies examine HIV/AIDS and often there is a lack of consensus among researchers and policy-makers regarding the importance of mandatory or voluntary testing within a prison setting. This article revisits and extends this discussion by presenting arguments and issues related to testing inmates. A comparison of selected factors indicated that mandatory testing is an important adjunct to minimizing the impact of the spread of the virus both within prison and in the non-offender population.

Three strikes and you're out: demographic analysis of mandatory prison sentencing.

Much of the debate about the costs and benefits of "three-strikes" laws for repeat felony offenders is implicitly demographic, relying on unexamined assumptions about prison population dynamics. However, even state-of-the-art analysis has omitted important demographic details. We construct a multistate life-table model of population flows to and from prisons, incorporating age-specific transition rates estimated from administrative data from Florida.

Prior and proximate causes of infant survival in Ghana, with special attention to polygyny.

This study examines the role of marriage form in infant mortality and tests the relative effects and mechanisms through which polygyny affects infant survival. A sample of infants born in the 5 years preceding the 1988 Ghana Demographic and Health Survey was used. A causal model was constructed and polygyny was found to be an important mediating factor in understanding infant survival.
