Practitioner perspectives on rapport building during child investigative interviews

The inclusion of a rapport phase with children in investigative interviews is considered best practice as research shows that this can improve the quality of information provided. However, the phenomenon of ‘psychological rapport’, as demonstrated in a person's behaviour, is less understood. Specifically, how do practitioners build rapport with children in the rapport phase? The aim of this paper is to provide information on the methods used by practitioners for building rapport with children, with an explanation of how they may influence communication. Nineteen Scottish practitioners (police officers and social workers) were interviewed about their experiences and approach to rapport building with children in investigative interviews. These interviews were qualitatively analysed using a grounded theory approach and produced a model for the relationship between psychological rapport and children's communication. According to this group of practitioners, rapport building acts as a ‘communication tool’ and is approached using three main strategies. These strategies involve using rapport to assess the child, adjust interview approach based on the assessment, and produce a change in the child's psychological state that facilitates communication. These findings have established practitioner understanding of rapport building and highlighted a number of areas that require further research.     

How Can African Governments Reach Poor Farmers with Fertiliser Subsidies? Exploring a Targeting Approach in Ghana

African governments have been pursuing reforms to improve the targeting of fertiliser subsidy programmes, but recent experience suggests that these reforms have not ensured that subsidies reach intended beneficiaries. Using a targeting approach based on proxy means tests with carefully selected indicators, this paper suggests that Ghana’s fertiliser subsidy programmes can be targeted to the country’s poor and smallholder farmers more efficiently and more cost-effectively. While a universal subsidy in 2012 is estimated to have reached 11 per cent of poor farmers, the proposed targeting approach would have reached 70 per cent of the poor farmers in northern Ghana and 50 per cent of poor farmers in southern Ghana. Targeting reduces the costs of leakages by about 72 per cent, thus justifying the costs of administering targeted programmes using the poverty proxies. Furthermore, we show that once the initial models are constructed, the targeting approach can be used for nearly 20 years without any significant losses in accuracy. We propose that policy-makers should consider implementing this targeting approach on a pilot scale involving a few communities and, if found successful in practice, in a larger-scale programme.     

A Comparison of Solvent Extract Cleanup Procedures in the Analysis of Organic Explosives

The use of an organic solvent to extract explosive residues from hand swabs and postblast debris inevitably leads to the coextraction of unwanted materials, usually in far greater quantities than any explosive residue. In this study, the extraction efficiency of a number of solvent cleanup procedures including solid‐phase extraction (SPE), adsorbent resins such as Chromosorb‐104, and traditional materials such as silica and Florisil was calculated using a quantitative liquid chromatography–ultraviolet (LC‐UV) detection procedure. The Oasis^® HLB cartridge outperformed other cleanup procedures, with analyte recoveries approaching 95%, while the Amberlite XAD‐7 procedure returned the lowest overall recoveries. The matrix rejection ability of each method was then determined using a simulated highly contaminated matrix, with the adsorbent resins showing a higher degree of matrix rejection, which is seen as a reduction in background noise in the UV chromatogram using 210 nm detection.     

A Comparison of Common Swabbing Materials for the Recovery of Organic and Inorganic Explosive Residues

The efficiency of solvent based extraction methods used to remove explosive residues from four different swab types was investigated. Known amounts of organic and inorganic residues were spiked onto a swab surface with acetonitrile or ethanol:water combined with ultrasonication or physical manipulation used to extract the residues from each swab. The efficiency of each procedure was then calculated using liquid chromatography‐ultraviolet detection for organic residues and ion chromatography for inorganic residues. Results indicated that acetonitrile combined with physical agitation proved to be the most efficient method; returning analyte recoveries c. 95% for both alcohol based swabs and cotton balls. Inorganic residues were efficiently extracted using ethanol:water, while the use of acetonitrile followed by water significantly reduced the recovery of inorganic residues. Swab storage conditions were then investigated with results indicating decreased storage temperatures are required to retain the more volatile explosives.     

The Development and Application of Random Match Probabilities to Firearm and Toolmark Identification

The field of firearms and toolmark analysis has encountered deep scrutiny of late, stemming from a handful of voices, primarily in the law and statistical communities. While strong scrutiny is a healthy and necessary part of any scientific endeavor, much of the current criticism leveled at firearm and toolmark analysis is, at best, misinformed and, at worst, punditry. One of the most persistent criticisms stems from the view that as the field lacks quantified random match probability data (or at least a firm statistical model) with which to calculate the probability of a false match, all expert testimony concerning firearm and toolmark identification or source attribution is unreliable and should be ruled inadmissible. However, this critique does not stem from the hard work of actually obtaining data and performing the scientific research required to support or reject current findings in the literature. Although there are sound reasons (described herein) why there is currently no unifying probabilistic model for the comparison of striated and impressed toolmarks as there is in the field of forensic DNA profiling, much statistical research has been, and continues to be, done to aid the criminal justice system. This research has thus far shown that error rate estimates for the field are very low, especially when compared to other forms of judicial error. The first purpose of this paper is to point out the logical fallacies in the arguments of a small group of pundits, who advocate a particular viewpoint but cloak it as fact and research. The second purpose is to give a balanced review of the literature regarding random match probability models and statistical applications that have been carried out in forensic firearm and toolmark analysis.     

Elder neglect and the pathophysiology of aging

Elder neglect, one of the 6 forms of elder maltreatment, is difficult to diagnose and is underreported both in the scientific literature and to law enforcement. Recognizing fatal neglect is even more challenging especially with concurrent organic disease. Many entities can mimic elder neglect, and many age-related changes can result in pathology that may be confused with maltreatment. We retrospectively reviewed all forensic cases of individuals age sixty-five years and older which were referred for autopsy. Cases of fatal neglect were analyzed as to age, sex, race, cause of death, location of incident, perpetrator, victim-to-perpetrator relationship, and autopsy and ancillary findings. The cases studies totaled 8. The age range was 74 to 94 years. Two were white, 6 black, one male, and 7 female. The causes of death were sepsis due to severe decubitus ulcers and severe dehydration. Five cases occurred in the victim's home, and 3 occurred in an institution (nursing home/care facility). In 5 cases, the perpetrators were family members. The pathophysiology of aging with respect to elder maltreatment is reviewed.
