Markets,Hierarchies, and Networks: An Agent‐Based Organizational Ecology

Markets, hierarchies, and networks are widely understood to be the three primary forms of social organization. In this article, we study the choice between these forms in a general, agent‐based model (ABM) of cooperation. The organizational ecology is the product, an emergent property, of the set of choices made by agents contingent on their individual attributes and beliefs about the population of agents. This is one of the first attempts to theorize explicitly the choice between different organizational forms, especially networks and hierarchies, and certainly the first to do so in an ABM. The insights of the model are applied to current research on transnational networks, social capital, and the sources of hierarchy and especially autocracy.     

A population genetic database of cat breeds developed in coordination with a domestic cat STR multiplex

A simple tandem repeat (STR) PCR-based typing system developed for the genetic individualization of domestic cat samples has been used to generate a population genetic database of domestic cat breeds. A panel of 10 tetranucleotide STR loci and a gender-identifying sequence tagged site (STS) were co-amplified in genomic DNA of 1043 individuals representing 38 cat breeds. The STR panel exhibits relatively high heterozygosity in cat breeds, with an average 10-locus heterozygosity of 0.71, which represents an average of 38 breed-specific heterozygosities for the 10-member panel. When the entire set of breed individuals was analyzed as a single population, a heterozygosity of 0.87 was observed. Heterozygosities obtained for the 10 loci range from 0.72 to 0.96. The power for genetic individualization of domestic cat samples of the multiplex is high, with a probability of match (p(m)) of 6.2E-14, using a conservative θ = 0.05.     

The Programme de recherche en démographie historique: past,present and future developments in family reconstitution

The Programme de recherche en démographie historique (Historical Demography Research Programme) (PRDH), founded in 1966 and based at the Département de Démographie of the Université de Montréal, has since its inception featured a central project, a family reconstitution database of Quebec’s Catholic population from 1621 to 1799 named the Registre de la population du Québec ancien (Population Register of Historic Quebec) (RPQA). This article, which marks the fiftieth anniversary of the project, explores the development of the RPQA over the five decades in the context of similar international databases, explains the current state of the database as well as our record linkage methodology, describes an important collaboration now underway to build a larger Quebec historical data infrastructure, outlines new and renewed international collaborations, and summarizes research conducted using these data as well as future research possibilities. The particular geographic context, historical development and manageable colonial population size of Quebec favoured family reconstitution of the whole colony from the beginning of the project. Today, the RPQA comprises 438,193 individual biographies and 74,000 family files encompassing up to nine generations. To reconstitute families, we must identify and incorporate into the database all demographic events, including those whose existence can only be inferred through other sources. Future efforts to link nineteenth-century parish acts will need to deal with large case counts, mixed Catholic–Protestant marriages, and increased geographic and social mobility. The integration of complementary data will provide information on household co-residence, occupations, help track the destinies of mixed-religion persons and persons outside nuclear families and provide additional points of observation.     

The role of a small town in rural development: A Sierra Leone case study

The distribution of services, personnel, and infrastructure in rural development projects has not usually been subject to a thorough scrutiny. Locational decisions have been arbitrary, without reference to the needs and mobility of the rural population. This study advocates one particular revision of past policies: the incorporation of small towns into programs designed to improve agricultural production and economic opportunity in rural regions. When such towns already function as a center for political activity, marketing, employment, and service provision, a development project can reinforce these linkages in ways that enhance productivity. A case study is used to illustrate the efficacy of this proposal: the town of Panguma, Kenema District, Sierra Leone and its role in development programs. Panguma has several features that make it an ideal focal point, but it has not been incorporated into regional projects in any systematic way. This town and its hinterland provide an illustration of how rural-urban interaction at a local scale can further the achievement of rural development goals. C.A.R.E.     

Humiliation,Manipulation, and Control: Evidence of Centrality in Domestic Violence Against an Adult Partner

This paper describes two related studies. Study 1 is a literature review of existing adult partner domestic violence assessment scales. Results of the review revealed that the scales varied on the available amount of empirical evidence for validity and reliability. More importantly, results showed that the content of the scales focused most heavily on the physical abuse aspects of domestic violence. Study 2 is a factor analysis performed on the results of 64 items taken from the Artemis Intake Questionnaire, a clinically relevant tool constructed by treatment providers used in working with the victims of domestic violence. Results indicate that reported humiliation and blame of the victim accounted for the largest amount of variance, followed by controlling the victim, and then physical violence. Results of this factor analysis suggest that greater emphasis must be put on factors other than physical violence in the construction of future domestic violence scales.     

Drug abuse's smallest victims: in utero drug exposure

The social and economic impact of drug use on our global population continues to increase leaving no geographical, social or cultural group untouched. The National Institute on Drug Abuse (NIDA), in one of the few large surveys of maternal abuse, found that 5.5% of mothers reported taking an illicit substance during gestation. These figures certainly are underestimates due to the stigma of drug use during pregnancy and the accompanying legal, ethical and economic issues. Although drugs of choice and routes of administration vary by country, exposure of our most valuable resource, our children, to the developmental effects of drugs is an enormous problem. In utero drug exposure can have a severe impact not only on the development of the fetus, but also on the child during later stages of life. More than 75% of infants exposed to drugs have major medical problems as compared to 27% of unexposed infants. The cost of treating drug-affected infants was twice the cost of non-affected infants. Obstetrical complications including placental insufficiency, miscarriage, intrauterine death, and increased incidence of infectious and sexually-transmitted diseases are higher in the drug-abusing mother. Treatment for pregnant addicts should be a high priority for our governments. Increased awareness and improvement in our understanding of drug abuse in the medical, legal and social realms will enable us to reduce the barriers to treatment for this important population.Accurate identification of in utero drug exposure has important implications for the care of the mother and child, but can raise difficult legal issues. Society discourages prenatal care with the infliction of harsh criminal penalties. Maternal drug use during pregnancy can be monitored with urine, sweat, oral fluid and/or hair testing. Detection of in utero drug exposure has traditionally been accomplished through urine testing; however, the window of detection is short, reflecting drug use for only a few days before delivery. Monitoring exposure through testing of alternative matrices, such as neonatal meconium and hair, offers advantages including non-invasive collection and detection earlier in gestation. There are many unresolved issues in monitoring in utero drug exposure that urgently require research. These can be divided into research to definitively differentiate drug exposed and non-drug-exposed fetuses, determine the most efficient methods to routinely monitor women's drug use, and determine how these drug test results relate to neonatal and maternal outcomes. Research in this area is difficult and expensive to perform, but necessary to assess accurately drug effects on the fetus. By increasing our understanding of the physiological, biochemical and behavioral effects of gestational drug exposure, we may ultimately provide solutions for better drug prevention, treatment and a reduction in the number of drug-exposed children.     

A strategy for accelerating the use of energy conserving building technologies

To accelerate the use of energy-conserving building technologies in the farflung, decentralized buildings industry, a strategy for more directed transfer of government research to public- and private-sector users has been implemented. The strategy involves a cycle of four sets of activities: (1) Needs assessment; (2) development of transferable information; (3) outreach activities; and (4) feedback and evaluation. By employing this iterative technology transfer cycle and emphasizing trade and professional organizations as communication channels to and from users, it is hoped that research sponsored by the U.S. Department of Energy's Building Systems Division will be responsive to the industry's needs and accessible to its diverse participants.
