Can Reinforcement Induce Children to Falsely Incriminate Themselves?

This study examined whether reinforcement can induce children to falsely incriminate themselves. Ninety-nine children in kindergarten through third grade were questioned regarding the staged theft of a toy. Half received reinforcement for self-incriminating responses. Within 4 min reinforced children made 52% false admissions of guilty knowledge concerning the theft, and 30% false admissions of having witnessed it. Corresponding figures for controls were 36 and 10%. Twelve percent of children admitted to participating in the theft, but the effect of reinforcement was only marginally significant. The findings indicate that reinforcement can induce children to falsely implicate themselves in wrongdoing.     

GitHub use in public administration in Canada: Early experience with a new collaboration tool

GitHub is a web‐based digital project hosting service that facilitates collaboration. We introduce how GitHub works and assess how it has been used in the public sector in Canada based on interviews with federal government leaders and a survey of Canadian public service GitHub users. With little research to date on public sector use of GitHub, and none on its use in Canadian governments, we explore the early experience with this collaboration tool and consider the possible implications for collaboration in government.     

Detecting Lies in Children and Adults

In this study, observers' abilities to detect lies in children and adults were examined. Adult participants observed videotaped interviews of both children and adults either lying or telling the truth about having been touched by a male research assistant. As hypothesized, observers detected children's lies more accurately than adults' lies; however, adults' truthful statements were detected more accurately than were children's. Further analyses revealed that observers were biased toward judging adults' but not children's statements as truthful. Finally, consistent with the notion that there are stable individual differences in the ability to detect lies, observers who were highly accurate in detecting children's lies were similarly accurate in detecting adults' lies. Implications of these findings for understanding lie-detection accuracy are discussed, as are potential applications to the forensic context.     

Fluorescent TiO2 powders prepared using a new perylene diimide dye: applications in latent fingermark detection

A new, highly fluorescent dye was synthesised using oleylamine combined with a perylene dianhydride compound. The new dye was characterised by 1H NMR, UV-vis spectroscopy and fluorescence spectroscopy as well as quantum yield. The dye was absorbed onto titanium dioxide nanoparticles for use as a fingerprint detection powder. The new fluorescent powder was applied to latent fingermarks deposited onto different non-porous surfaces and compared with commercial fluorescent powders. The powder exhibits strong fluorescence at 650-700 nm under excitation at 505 nm. On glass surfaces, the new powder gave images showing tertiary-level detail of the fingermark ridges with almost no background development. Compared with current magnetic fluorescent powders, the new powder was slightly weaker in fluorescence intensity but produced significantly less background development, resulting in good contrast between the fingermark and the substrate.     

Direct and Indirect Services for Children in Domestic Violence Shelters

The majority of women entering battered women’s shelters bring children with them and those children often require specialized programs that address the ways in which witnessing domestic violence has affected them. Several programs have been developed and implemented; however, few have been empirically evaluated. The current article critically examines several intervention strategies and their effectiveness. Barriers to service are also identified. Although there is a paucity of research in this area, the present review suggests that intervening with children may show promise for breaking the cycle of violence.
