Police Psychology in Singapore: The Red Dot Experience

Despite developments in police psychology in North America and Europe, little is known about developments in other parts of the world. Yet, this knowledge will reinforce the development of the field of police psychology internationally and strengthen its scientific theories, practices and programs. This paper therefore traces the development of police psychology in Singapore for over two decades across four waves of development. This paper also describes the developments in three areas of police psychology (services to police officers, police operations and the police organization) and details the various police psychological services programs and services in Singapore. The paper concludes with a discussion on strategic concerns for police psychologists worldwide, arguing that there is a need to discuss the ‘what works, when and where?’ in police psychology, when it is applied across the world.     

Optimization of Human mtDNA Control Region Sequencing for Forensic Applications

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.     

The relationship between investigative interviewing experience and open-ended question usage

We present three studies examining the role of prior job experience in interviewing and interviewers' ability to learn open-ended questions during a training program. We predicted a negative relationship such that more experienced interviewers would perform worse after training than less experienced interviewers, and that (irrespective of baseline performance) the more experienced interviewers would improve the least during training. These predictions were made for two reasons. First, specific questions are commonly used in the workplace (i.e. open-ended questioning constitutes new learning). Second, experience in the use of specific questions potentially interferes with newly learned open-ended questions. Overall, our predictions were supported across different participant samples (including police officers specialized in child abuse investigation and social workers from the child protection area), time delays, and modes of training. The results highlight the need for investment in ongoing investigative interviewing training commencing early during professionals' careers, prior to the establishment of long-term habits in the use of specific questions.     

The Role of Perceived Deservingness in the Toleration of Human Rights Violations

Based on evidence that people have a strong need to see that individuals get what they deserve, we reasoned that people will tolerate a human rights violation to the extent that they believe the target of the violation deserves severe treatment. Thus, we expected that variables that influence the perceived deservingness of a target (i.e., “contextual cues” to deservingness) should influence toleration of a violation of the target’s rights, mediated by perceptions of the target’s deservingness. We also expected that the effect of a contextual cue to targets’ deservingness on toleration should occur even for people who support the violated right in the abstract. Across two studies, using student versus community samples, we measured participants’ abstract support for the right to humane treatment. We then presented participants with scenarios about a target who was tortured (a violation of the right to humane treatment), and manipulated a contextual cue to the targets’ deservingness for severe treatment—the moral reprehensibility of the targets’ past behavior. Participants tolerated a target’s torture more if he had engaged in highly morally reprehensible (vs. less reprehensible) behavior and, thus, was perceived to deserve more severe treatment. Participants’ abstract support for the right to humane treatment did not moderate the effect of moral reprehensibility on toleration. Our findings highlight the importance of perceived deservingness in the toleration of human rights violations and have implications for reducing such toleration. Our research also extends literature on deservingness to an important global issue.     

Incentives and their dynamics in public sector performance management systems

We use the principal‐agent model as a focal theoretical frame for synthesizing what we know, both theoretically and empirically, about the design and dynamics of the implementation of performance management systems in the public sector. In this context, we review the growing body of evidence about how performance measurement and incentive systems function in practice and how individuals and organizations respond and adapt to them over time, drawing primarily on examples from performance measurement systems in public education and social welfare programs. We also describe a dynamic framework for performance measurement systems that takes into account strategic behavior of individuals over time, learning about production functions and individual responses, accountability pressures, and the use of information about the relationship of measured performance to value added. Implications are discussed and recommendations derived for improving public sector performance measurement systems. © 2010 by the Association for Public Policy Analysis and Management.     

A Preliminary Investigation into the Accuracy of 3D Modeling and 3D Printing in Forensic Anthropology Evidence Reconstruction,

There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence.     

Distinguishing Two Meanings of Moral Exclusion: Exclusion from Moral Principles or Principled Harm-Doing?

The concept of “moral exclusion” has often been used to understand harm-doing. The present studies examined two, distinct meanings that have been ascribed to this concept. First, exclusion has sometimes been conceptualized as the belief that moral principles do not apply to a target person or group (e.g., exclusion from the application of justice principles). Second, the term has been used to refer to exclusion from positive treatment that is accorded to others, which the actors believe to be morally justified, though outside observers do not. Distinguishing between these two meanings can clarify the mechanisms underlying the relation between proposed antecedents to exclusion and harm-doing. In two experiments, we obtained evidence compatible with each of these conceptualizations of exclusion, as well as preliminary evidence that certain antecedents are more likely to lead to processes indicative of one or the other conceptualization. Our findings have practical implications for the reduction of harm-doing as well as for conflict that might arise in such attempts.
