Some have argued that community policing represents a reform that is capable of increasing neighborhood social capital. Collaborative relationships between police and communities are expected to enhance the capacity of residents to collectively ameliorate neighborhood conditions. This study examines the relationship between police-community coproduction and neighborhood-level social capital using data from a survey of neighborhood leaders. Results provide partial support for the claim that community policing is related to social capital. More specifically, collective social capacity was shown to be higher in neighborhoods where residents perceive the police to be more accessible. Future considerations for the study of community policing and social capital are discussed.

An international effort is underway to generate a comprehensive haplotype map (HapMap) of the human genome represented by an estimated 300,000 to 1 million 'tag' single nucleotide polymorphisms (SNPs). Our analysis indicates that the current human SNP map is not sufficiently dense to support the HapMap project. For example, 24.6% of the genome currently lacks SNPs at the minimal density and spacing that would be required to construct even a conservative tag SNP map containing 300,000 SNPs. In an effort to improve the human SNP map, we identified 140,696 additional SNP candidates using a new bioinformatics pipeline. Over 51,000 of these SNPs mapped to the largest gaps in the human SNP map, leading to significant improvements in these regions. Our SNPs will be immediately useful for the HapMap project, and will allow for the inclusion of many additional genomic intervals in the final HapMap. Nevertheless, our results also indicate that additional SNP discovery projects will be required both to define the haplotype architecture of the human genome and to construct comprehensive tag SNP maps that will be useful for genetic linkage studies in humans.

Case studies may represent a valuable source of data for testing the theoretical propositions related to community policing. The utility of this approach depends on the extent to which case studies assess coproduction interactions between police and residents. This study utilizes a measurement protocol to systematically extract these interactions from case studies. After assessing the reliability and the validity of these measures, the authors conclude that there is some utility in using case studies for this purpose. Case studies are a better source of information about the presence or absence of certain coproduction interactions and about the dispersion of these interactions over people, places, and organizations. Case studies are a weaker source of information about the temporal fluctuations in coproduction. The strengths and limitations of this approach are discussed.
