Computer simulation models have changed the ways in which researchers are able to observe and study social phenomena such as crime. The ability of researchers to replicate the work of others is fundamental to a cumulative science, yet this rarely occurs in computer simulations. In this paper, we argue that, for computer simulations to be seen as a legitimate methodology in social science, and for new knowledge to be generated, serious consideration needs to be given to how simulations could or should be replicated. We develop the concept of systematic replication, a method for developing simulation experiments that move towards a generalisable inference that is directed, explicit, and incorporates complexity incrementally. Finally, we outline how the discrete parts of this process might be carried out in practice, using a simple simulation model.

Before this he was a Senior Research Fellow at the University College London (UCL) Jill Dando Institute of Crime Science, University College London. He trained as a statistician, and his research has focused on crime analysis, problem-orientated policing and quantitative methods in a criminal justice setting, all with a view to preventing crime. His current research projects include the spatial and temporal modelling of crime and the analysis of large novel data sets. Daniel Birks   is a Research Fellow at the UCL Jill Dando Institute of Crime Science. He has worked on a number of crime prevention research projects in conjunction with the Home Office and several police forces in the UK. His research interests include the development of innovative crime analysis and decision support techniques and tools, prospective models of crime, the application of simulation techniques within criminology, the study of offender predation patterns, and the use of data mining in crime analysis.  相似文献

The performance of innovation systems depends, to a great extent, on the degree of public–private collaboration they involve. Thus, innovation policies often aim to enhance this collaboration through public–private partnerships. These partnerships are a multidimensional phenomenon whose success depends on factors related to each of their dimensions. This paper proposes the use of an analytical model that reflects the multidimensional nature of public–private partnerships and analyses to what extent they are applied in a specific innovation system in order to identify the territorial and sectorial factors that act as barriers or drivers to use them. This model aims to help policy makers design appropriate public–private partnerships in each context. The case under review is the Spanish innovation system, given that this system has been suffering from a structural lack of collaboration for several decades, despite the implementation of policies aimed to foster this. Thus, if the model works, it should be able to identify key factors that influence greater or more restricted use of the different PPP formulas.  相似文献

Juror and jury research is a thriving area of investigation in legal psychology. The basic ANOVA and regression, well‐known by psychologists, are inappropriate for analysing many types of data from this area of research. This paper describes statistical techniques suitable for some of the main questions asked by jury researchers. First, we discuss how to examine manipulations that may affect levels of reasonable doubt and how to measure reasonable doubt using the coefficients estimated from a logistic regression. Second, we compare models designed for analysing the data like those which often arise in research where jurors first make categorical judgments (e.g., negligent or not, guilty or not) and then dependent on their response may make another judgment (e.g., award, punishment). We concentrate on zero‐inflated and hurdle models. Third, we examine how to take into account that jurors are part of a jury using multilevel modelling. We illustrate each of the techniques using software that can be downloaded for free from the Internet (the package R) and provide a web page that gives further details for running these analyses.  相似文献

Motor vehicle driver fatalities (≥18 years) from the files at Forensic Science South Australia were reviewed from January 2008 to December 2018 for cases in which either positive blood sample for methamphetamine (MA) or an illegal blood alcohol concentration (BAC) >0.05g/100 ml were found. Three hundred driver deaths were found with MA detected in 28 cases (age range 21–62 years; ave. 37.8 years; M:F 23:5). Hundred and fifteen cases with a BAC > 0.05 g/100 ml were identified (age range 18–67 years; ave 35.7 years; M:F 95:20). No change was found in numbers of MA cases, although alcohol cases showed a significant decline (p < 0.001). Drunk driving-related fatal crashes tended to occur in the evening (5 p.m. to 11 p.m.), while MA-related fatal crashes had a longer peak extending from late evening until late morning (11 p.m. to 8 a.m.). This study has demonstrated that while roadside breath testing, legislative changes, and increased monitoring have resulted in reduced levels of drunk driving, similar safety countermeasures have had negligible effects on MA use in drivers. Continued monitoring of MA use by drivers will, therefore, be necessary to assess the possible effects, or not, of new countermeasures.  相似文献

This is the golden age of economic statecraft—and the study of economic statecraft. This is in large part due to the evolution of economic coercion from trade embargoes to targeted financial sanctions. Targeted financial sanctions are attractive because they can generate economic costs similar to those of more comprehensive sanctions, with fewer negative externalities. Over time, however, the intersection of economic sanctions with globalized capital markets will provoke three interesting research questions. First, do financial sanctions spare a target country’s population from negative humanitarian and human rights outcomes? Second, to what extent are financial sanctions an exercise in learning by both targets and senders? Third, will the United States’ use of financial sanctions trigger blowback against US primacy in the international financial system? These last two questions offer the prospect to linking research on economic statecraft with larger questions of international security and global political economy.  相似文献

Southern Brazil is unique due to its subtropical climate. Here, we report on the first forensic entomology case and the first record of Sarconesia chlorogaster (Wiedemann) in a human corpse in this region. Flies' samples were collected from a body indoors at 20°C. Four species were found, but only Chrysomya albiceps (Wiedemann) and S. chlorogaster were used to estimate the minimum postmortem interval (mPMI). The mPMI was calculated using accumulated degree hour (ADH) and developmental time. The S. chlorogaster puparium collected was light in color, so we used an experiment to establish a more accurate estimate for time since initiation of pupation where we found full tanning after 3 h. Development of C. albiceps at 20°C to the end of the third instar is 7.4 days. The mPMI based on S. chlorogaster (developmental time until the third instar with no more than 3 h of pupae development) was 7.6 days.  相似文献

Although there is growing research interest in populist radical right (PRR) parties in Western Europe, little attention has been paid to the case of Spain – a country where these parties are almost non-existent or irrelevant from an electoral and political point of view. In a nutshell, we maintain that in contemporary Spain there is real demand for PRR parties, but three supply-side factors are impeding their electoral breakthrough and persistence: the cleavage structure of the country, the strategy of competition of the mainstream right and the electoral system. At the same time, we postulate that at least in the case of Spain the Great Recession has not improved the electoral odds of the PRR as such but rather facilitated the emergence of leftist populist forces.  相似文献

Family courts are seeing an increasing number of separating or divorced families who have a special needs child. These cases present complex challenges for family law professionals charged with crafting parenting plans based on best interests standards. For many of these children, the typical developmentally based custodial arrangements may not be suitable, given the child's specific symptoms and treatment needs. We present a model for understanding how the general and specific needs of these children, as well as the demands on parents, can be assessed and understood in the context of divorce. This includes an analysis of risk and protective factors that inform timeshare and custodial recommendations and determinations. The risk assessment model is then applied to three of the most commonly occurring childhood neurodevelopmental and psychiatric disorders likely to be encountered in family court, namely, attention deficit/hyperactivity disorder, depressive disorders, and autistic spectrum disorders.
    Key Points for the Family Court Community
  • There has been a dramatic rise in the population of children with neurodevelopmental, psychiatric, and medical syndromes whose parents are disputing custody in the family courts.
  • Family law professionals of all disciplines should develop a fundamental knowledge base about the most commonly seen special needs children in family court, such as those with neurodevelopmental conditions like autistic spectrum disorder, attention deficit/hyperactivity disorder, and severe depressive disorders (especially with teenagers), which may involve suicidal or self‐harming behaviors.
  • Commonly recommended parenting plans may be inappropriate for many special needs children, as some function significantly below their chronological age and pose extreme behavioral challenges.
  • A systematic analysis of risk and protective factors should inform timeshare arrangements and determinations with this varied population, including the safety of the child and severity of the disorder, parental commitment and availability to pursue medical, educational, and therapeutic services, the parental attunement and insightful about the problem, and the differential parenting skills of each parent.
