An exercise in scientific problem-solving: Illustrating the utility of the principles of the Sydney Declaration

In forensic science, scientific problem-solving is characterized by the recognition of traces as part of iterative reasoning processes to assign meaning to those traces in order to interpret and reconstruct events. Through a set of fundamental principles, the Sydney Declaration presents a foundation of forensic science through the lens of a scientist. The distinction between a scientist and a technician may require clarification—where a prototypical technician follows a prescribed set of ‘standard operating procedures’ and may be limited in the interpretation of the resultant data, the scientist utilizes knowledge, skills, experience and imagination to identify the issue at hand and develop lines of inquiry for testing and interpretation. This case report draws on the Sydney Declaration in order to highlight the importance of learning about events from careful consideration of both obvious and less obvious traces. A case involving the assault of a police officer is examined to illustrate the use of the Principles: the problem originally defined by investigators at the scene and later by prosecutors resulted in incorrect analysis and interpretation of traces, hampering efforts at an accurate reconstruction of events. This exercise serves to demonstrate that in order to engage in scientific problem-solving, it is necessary to apply observation and reasoning in forensic investigations in order to yield an outcome that can be clearly articulated. The overarching goal is to support the drive to improve forensic science practice, education, and research through a case illustrating the value of the principles of the Sydney Declaration.     

Scientific Research on the Efficiency of Public Expenditures: How and Where is it Going?

ABSTRACT

Recent scientific research has advanced the measurement of the relative performance of organizations and the efficiency of public spending, based on analyzes of the services offered and results achieved. However, from the methodological point of view, there are several methods to analyze the performance and efficiency of spending in the private and public sectors. In this sense, the present study performs a systematic bibliometric review to analyze all scientific publications on the efficiency of public spending published in the last 20 years. The results show that most cost-efficiency analyzes have been limited to education and health expenditures and have used quantitative analysis, mainly through the application of data-involution analysis. The present review is a first step in mapping scientific publications on efficiency in public spending, which will support researchers and managers to make public spending more efficient.     

Cross-Cultural Lessons on Anger and Social Connectedness

I first started thinking about anger and its role in the experiences of people who have fought in wars when I was in Sierra Leone, about a year after the cease-fire ended the civil war. I was working as a research assistant on a study with girls who had been child soldiers and who had given birth to children during the war. We were living in a community in the west, on the border with Guinea. At first, we met only a few young women. We listened to their stories—about the war, and about what life had been like for them and their children since the end of hostilities.

As days passed, word got around in this rural community that women had come to listen to the experiences of young mothers who had been child soldiers. Girls and young women living in small huts in the jungle surrounding the town, or sharing a house on the edge, began to come with their babies and introduce themselves and tell us their stories. Amid the grief and despair, the worry about how they would have enough food for the next day, I could hear a simmering rage from many young women: anger at not just what had occurred during the war, but how they had been treated when they returned.

Rap Music Genres and Deviant Behaviors in French-Canadian Adolescents

This study investigated the links between the preference for 4 rap music genres (American rap, French rap, hip hop/soul, and gangsta/hardcore rap) and 5 types of deviant behaviors in adolescence (violence, theft, street gangs, mild drug use, and hard drug use). The effects of peers' deviancy, violent media, and importance given to lyrics were statistically controlled. A self-report questionnaire was distributed to a sample of 348 bilingual French-Canadian adolescents (age: M = 15.32; SD = 0.9; 185 girls and 163 boys). Results indicated that rap music as a whole was linked to deviant behaviors, however the nature of the relation differed according to genres. Preference for French rap had the strongest links to deviant behaviors, whereas preference for hip hop/soul was linked to less deviant behaviors. Results are discussed within the psychosocial and sociocognitive perspectives on music influence in adolescence and also within the perspective of normative deviant behaviors in adolescence.     

Does Post-identification Feedback Affect Evaluations of Eyewitness Testimony and Identification Procedures?

Two experiments were conducted to test whether post-identification feedback affects evaluations of eyewitnesses. In Experiment 1 (N = 156), evaluators viewed eyewitness testimony. They evaluated witnesses who received confirming post-identification feedback as more accurate and more confident, among other judgments, compared with witnesses who received disconfirming post-identification feedback or no feedback. This pattern persisted regardless of whether the witness’s confidence statement was included in the testimony. In Experiment 2 (N = 161), witness evaluators viewed the actual identification procedure in which feedback was delivered. Instructions to disregard the feedback were manipulated. Again, witnesses who received confirming feedback were assessed more positively. This pattern occurred even when witness evaluators received instructions to disregard the feedback. These experiments are the first to confirm researchers’ assumptions that feedback effects on witnesses translate to changes in judgments of those witnesses.     

The emperor's cloths of disclosure: Hot money and suspect disclosures

This paper describes the results of the analysis of the Dutch database of suspect financial transactions for the years 1994-1996. It provides a detailed insight into the money volume at risk, the reasons for disclosure and the persons and corporations involved. The results show that from the start 48% of the disclosed money reports had to be discarded as there was either no money involved or there was no crime-money. The remaining database showed that all the distributions were very skewed resulting in the conclusion that “few move little money and few move much” or 179 persons were responsible for 89% of the disclosed money movements. The paper raises some questions about the assumptions underlying the anti-money laundering policy and the requirements for designing an adequate disclosure system at a European level. This revised version was published online in July 2006 with corrections to the Cover Date.     

From “sensed” to “complex”: some reflections on borders throughout history

The concept and definition of borders has evolved significantly over time. In Europe the twentieth century alone has seen remarkable changes. At the beginning of the century borders represented the clear end of the sovereignty of one state and the beginning of another while the second half of the same century brought revolutionary concepts of state borders. This article aims to contribute towards the conceptual discussion of borders, tracing some of the journey of this concept, from centuries ago when they were perceived as more ”sensed”, to more recent interpretations of ”solid” and “liquid” borders to today's “complex” borders.     

Establishing Tobacco Origin from Pollen Identification: An Approach to Resolving the Debate

Previous research into pollen content of tobacco resulted in a debate. We address this debate and determine that pollen analysis may be able to assist with identifying geographical origin of tobacco. However, the value of any results should be assessed on a case‐by‐case regional basis until sufficient database information is available for an objective interpretation to be undertaken on a global basis. As a first step toward developing comparative data for South America, we analyzed a tobacco sample from Brazil in an effort to identify signature taxa from the state of Minas Gerais. We also assessed the role of honey additives to tobacco to assess this issue. Comparing the data to previously published data, we conclude that pollen signatures can distinguish broad geographic areas. We conclude that this forensic interpretation framework needs to be developed in context of the National Academy of Sciences recommendations for tightening methods in forensic science.
