    Notes: Abstract In this paper several examples of government contracts with private firms are examined to see how experience conforms to a principal-agent model of cost minimization via competitive bidding and how important are the many qualifications to the model. Fifteen cases of local government contracting are examined. The course of private contracting is not always smooth — as judged by the many contract disruptions observed and by the number of cities that believe they are no longer saving money by contracting and those which have resumed public production. It also seems to be the case, however, that competition generally reduces initial costs, that in many cases cost savings persist, that it is possible to stimulte competition, and that providing for continual interaction, as contrasted with simply monitoring performance, can prevent disruption.

    Notes: Abstract An LDV system for making spatial correlation measurements of velocity fluctuations in turbulent nonreacting and reacting flows is presented. The LDV system is the dual beam type and consists of an elongated probe volume and a two-point optical fiber detector. Results are presented of the integral length scale measured in a nonreacting grid generated turbulent flow.

    Regional assignment of the genes for TK1, GALK, ALDC, and ESD on chromosome 8 in the American mink by chromosome-mediated gene transfer (1985)
    Springer
    Molecular genetics and genomics 200 (1985), S. 433-438 
    Details
    ISSN: 1617-4623
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A panel of clones of mink-Chinese hamster somatic cell hybrids was analysed to obtain data for assigning the genes for thymidine kinase-1 (TK1), galactokinase (GALK), subunit C of aldolase (ALDC), and esterase D (ESD) to specific mink chromosomes. The results demonstrate that the genes for TK1, GALK, ALDC and ESD are syntenic and located on mink chromosome 8. Prometaphase analysis of transformed mouse cells obtained by transfer of mink genes by means of metaphase chromosomes demonstrated the presence of mink chromosome 8 fragments of different sizes in some of the independent transformants. Segregation analysis of these fragments and mink TK1, GALK, ALDC and ESD allowed us to assign the genes for TK1 and GALK to 8p24, ALDC to pter-8p25, and ESD to 8q24-8qter.

    Transfer of mink genes into mouse cells by means of isolated lipid-encapsulated nuclei (1985)
    Springer
    Molecular genetics and genomics 201 (1985), S. 487-491 
    Details

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A method for gene transfer by means of interphase nuclei encapsulated within lipid membranes was developed. The method was based on passage of interphase nuclei through a layer of organic solvents containing phospholipids. Evidence was obtained indicating that the nuclei become surrounded by a protective phospholipid membrane: measurements of bound labelled or non-labelled phospholipids; decrease in the permeability of lipid-encapsulated nuclei for high molecular compounds; visualization by direct electron microscopy. Lipid-encapsulated nuclei of mink fibroblasts were used for transformation of mutant mouse LMTK- cells (deficient for thymidine kinase). The frequency of occurrence of HAT-resistant colonies/recipient cell was 1.9x10-5. Biochemical analysis of 14 independent clones demonstrated that they all contained TK1 of mink origin. Analysis of 15 other biochemical markers located on 12 of the mink chromosomes revealed the activities of mink galactokinase (a syntenic marker) in 5 transformed clones, and that of mink aconitase-1 (the marker of mink chromosome 12) in 1 clone. No cytogenetically visible donor chromosomes were identified in the transformed clones. Nine transformed clones were tested for the stability of the TK+ phenotype; of these, the phenotype was expressed stably in 3 and unstably in 6. The method suggested is similar to the gene transfer procedure using total DNA. Its advantage is in ensuring efficient gene transfer and donor DNA integrity.

    The political policy cycle: Presidential effort vs. presidential control (1987)
    Springer

    Notes: Abstract After disentangling presidential budget proposals from budgetary changes attributable to fluctuations in the economy and to congressional action, we find consistent evidence for a presidential macroeconomic policy cycle attuned to the elctoral cycle. Proposed budgets are more expansionary in election years than at other times. The Congress, however, also plays a significant role in determining fiscal outcomes. Its budgets are systematically related to those of the President and in general reinforce presidential efforts to respond to the electoral cycle. Although Presidents generally propose quite conservative budgets, their proposals are more expansionary in presidential election years than in other years. The Congress, which generally adopts an expansionary fiscal policy ratifies this proposed macroeconomic policy electoral cycle by adopting even more expansionary budgets in presidential election years than they do at other times.

    The Congress and fiscal policy (1988)
    Springer
    Public choice 58 (1988), S. 101-122 
    Details

    Topics: Economics
    Notes: Abstract Although the common belief is that the Congress has paid little attention to fiscal policy, the same kinds of political-economic models which have been used to explain presidential budgetary policy may be used equally well to explain congressional budgetary behavior. The Congress' fiscal policy appears to be systematically sensitive to both economic and political factors. Changes in the unemployment rate have a major impact on congressional budgetary policy. As for political factors, the President's lead is followed most closely on revenue proposals and not at all on the expenditure side. The electoral cycle, in particular the off-year congressional election year, is also important; inducing larger deficits and smaller increases in revenues. When the influences on congressional fiscal behavior are compared with those on presidential behavior, the sources of the generally more expansionary congressional fiscal policy are identified. Congressional budget deficits increase in response to increased rates of unemployment but are insensitive to increases in inflation. In contrast, presidential budgets are heavily influenced by inflation and the growth in personal income — increases in each resulting in smaller proposed deficits — as well as by unemployment rates. In years in which both unemployment and inflation are increasing, the combination of the two (assuming a one percentage point change in each) implies an increase in the congressional deficit of $6.7 billion but a decrease in the president's proposed deficit of $2.5 billion. The implications of this study are a challenge to the literature which makes the President the central actor in macro-economic policy.
