A search was conducted to find evidence of possible incestuous unions between the biologic parents of children involved in 2500 paternity cases. Suspicion was raised when either (1) a mother and her child possessed identical HLA phenotypes, or (2) the child appeared to be possibly homozygous for one maternal haplotype (i.e., one of the child's HLA haplotypes was a blank). These mother-child HLA-haplotype dualisms (MHDs) occurred in 5% of all cases. Frequency of exclusion of the accused men in cases demonstrating MHD, was compared with the remaining paternity cases.No significant difference was found in overall exclusion rates between MHD cases and controls when exclusion produced by HLA and red cell antigen systems were observed. However, there was a greater rate of exclusion in MHD cases when comparing exclusions produced by red cell antigen systems regardless of whether HLA tests excluded paternity (p < 0.025). MHD cases involving teenaged mothers differed from control cases in frequency of exclusion of paternity only on the basis of red cell antigen phenotyping (p < 0.005).The HLA system's usefulness in paternity testing is diminished when there is MHD; multiple, independently-inherited systems are relatively more useful in these circumstances.The search method detects only half of potential incest cases; proof of incest requires more extensive testing for homozygosity among other polymorphisms. Since calculations of likelihood of paternity are inappropriate in cases involving close consanguinity, detection and follow up studies are important.Data suggest that one-fifth of MHD cases may involve first degree consanguinity and that the incest rate among paternity cases may be as high as 2%. 相似文献

Strategic agricultural trade policy interdependence and the exchange rate: A game theoretic analysis
Strategic Agricultural Trade Policy Interdependence is modeled using a game theoretic framework. The model distinguishes between the European Community, the United States and a politically passive rest-of-the-world. Particular emphasis is placed on the effect of the exchange rate on the equilibrium outcome of this game. Without compensatory payments to those with the highest political influence, the results suggest that only modest reform is possible. With compensation, liberalization occurs but free trade is not obtained. Simulations also indicate that the U.S. gains incentive to reduce protection given a depreciation of the dollar, while incentive to liberalize trade policies decreases as the dollar appreciates. Research was supported by Minnesota Agricultural Experiment Station project 14065 “Economic Integration and Disintegration in Europe: Implications for U.S. Agriculture.” 相似文献

Abstract: The physical design and location of the existing Parliament House has influenced the evolution of Australia's parliamentary system. The new Parliament House will exert a new set of influences. The Executive will assume an entrenched position within its own enclave and Ministers will be physically more remote from backbenchers. The physical arrangements of the Executive entrance and the Prime Minister's suite will encourage a presidential-style status in the office. But the architecture also emphasises the public's access to Parliament in the spirit of Burley Griffin's original conception. There is likely to be a strong “congressional” impetus arising from the prominence given to committee room space and backbencher facilities. Tensions between the Executive and Parliament will be exacerbated. Changes to procedures and to parliamentary administration are also likely to flow from the new layout and facilities. The new building will provide an impetus for widespread parliamentary reform. 相似文献

Contracting has moved from the margins to the centre of public management. Significant sections of the public workforce, from benefits delivery to corporate services, now find their functions open to tender. Governments prefer to concentrate on policy analysis and development, leaving service delivery to the market. As purchasers rather than providers, governments are redefining the role and scope of the state. But are Australian governments ready for this shift to contracting? Do they possess the full array of control and reporting mechanisms necessary if contracting is to deliver its promised benefits? There are significant difficulties finding evidence that answers such questions. Yet on the basis of concerns discussed across Australian jurisdictions, it appears contracting has developed so quickly it outstrips the capacity of government to monitor what is happening, and so learn from mistakes. In time governments will become better at maintaining accountability for contracted functions, because experience reduces the risks of moral hazard. 相似文献

In previous research, family structure variables have been operationalized as family size, birth order, sibling spacing, and sibling density. These structure variables have been linked to parental strictness, reasonableness, and supportiveness [J. S. Kidwell (1981), Number of Siblings, Sibling Spacing, and Birth Order: Their Effects on Perceived Parent–Adolescent Relationships, Journal of Marriage and the Family, Vol. 43, pp. 315–333]. Other research has drawn attention to the link between the amount of time adolescents spend with parents and peers and the influence of family relations variables—intensity, duration, and frequency of conflicts. [R. Montemayor (1982), The Relationship Between Parent–Adolescent Conflict and the Amount of Time Adolescents Spend Alone and with Parents and Peers, Child Development, Vol. 53, pp. 1512–1519]. More recent research has related family structure (family size, sibling spacing, and gender) effects to the amount of time adolescents spend with parents, a measure of relationship quality, and a set of measures of discipline [R. A. Richardson et al. (1986), Parent–Child Relationships in Early Adolescence: Effects of Family Structure, Journal of Marriage and the Family, Vol. 48, pp. 805–811]. To date, the questions asked by researchers have not simultaneously explored whether it is the family relations or the family structure variables that contribute most powerfully to the amount of time that female and male adolescents spend with family members and peers. In this research adolescents were asked to report the amount of time they spend with their mother, father, siblings, and peers, and to respond to a questionnaire that has three factors that define family functioning: Parenting Style (democratic decision making), Intimacy, and Conflict [P. Noller et al. (1992), Parent and Adolescent Perceptions of Family Functioning: A Comparison of Clinic and Nonclinic Family, Journal of Adolescence, Vol. 15, pp. 101–115]. The analyses revealed that complex and interpretable family structure and family functioning factors differentially influence whether males and females spend time with family members and peers. 相似文献
