A fruitful parent of injustice: unilateral service of notice to quit by a joint tenant

‘A fruitful parent of injustice is the tyranny of concepts’ (Cardozo 1928). This warning seems apposite when reviewing the impact of the decision of the House of Lords in Hammersmith and Fulham London Borough Council v Monk [1992] 1 AC 478, HL. Since Monk the law is well settled that one joint tenant of a periodic lease can destroy the lease held by both joint tenants. This destructive ability is justified by a conceptual analysis that refuses to recognise the destructive effects of its utilisation. With a reform of the law on the horizon the time is ripe for a review of this peculiar area of law (see Law Com No 284). If we are correct in our analysis, Monk has been productive of an unnecessary amount of mischief in the law. This is partially due to the deployment of inappropriate concepts in Monk itself, and partially due to an unfortunate subsequent tendency to allow these concepts to act as tyrants in dictating legal development. Monk has had an effect directly or indirectly across many different areas of the legal landscape. This has necessitated both an unwelcome length and a complex structure for this article

Some current measurements in the Sargasso Sea

Also published as: Deep-Sea Research 12 (1965): 805-814Long-term current measurements at depths of 50 and 100m obtained with Richardson current meters at two deep-water moorings south of Bermuda are reported. The records are dominated by anticyclonic rotations which appear and degenerate, possibly in response to the passage of storms. Spectral analysis of the records indicates that this motion has a period of 24 hours at a depth of 50 m, and 25·3 hours at a depth of 100m. No explanation is given to account for this difference in period over a 50-m separation. Both records indicate the existence of semidiurnal tidal motion. The long-term motions at both depths indicate a systematic change in the net direction of flow over a three-month period.The Office of Naval Research under Contract Nonr-2196(00) NR 083-004

Mathematical programs with equilibrium constraints: automatic reformulation and solution via constrained optimization

Constrained optimization has been extensively used to solve many large scale deterministic problems arising in economics, including, for example, square systems of equations and nonlinear programs. A separate set of models have been generated more recently, using complementarity to model various phenomenon, particularly in general equilibria. The unifying framework of mathematical programs with equilibrium constraints (MPEC) has been postulated for problems that combine facets of optimization and complementarity. This paper briefly reviews some methods available to solve these problems and described a new suite of tools for working with MPEC models. Computational results demonstrating the potential of this tool are given that automatically construct and solve a variety of different nonlinear programming reformulations of MPEC problems.\ud \ud This material is based on research partially supported by the National Science Foundation Grant CCR-9972372, the Air Force Office of Scientific Research Grant F49620-01-1-0040, Microsoft Corporation and the Guggenheim Foundation

Improving medical image perception by hierarchical clustering based segmentation

It has been well documented that radiologists' performance is not perfect: they make both false positive and false negative decisions. For example, approximately thirty percent of early lung cancer is missed on chest radiographs when the evidence is clearly visible in retrospect. Currently computer-aided detection (CAD) uses software, designed to reduce errors by drawing radiologists' attention to possible abnormalities by placing prompts on images. Alberdi et al examined the effects of CAD prompts on performance, comparing the negative effect of no prompt on a cancer case with prompts on a normal case. They showed that no prompt on a cancer case can have a detrimental effect on reader sensitivity and that the reader performs worse than if the reader was not using CAD. This became particularly apparent when difficult cases were being read. They suggested that the readers were using CAD as a decision making tool instead of a prompting aid. They conclude that "incorrect CAD can have a detrimental effect on human decisions". The goal of this paper is to explore the possibility of using hierarchical clustering based segmentation (HSC), as a perceptual aid, to improve the performance of the reader

Daniel G. Philbrick: Steamboat Captain

Daniel Philbrick, born in New Hampshire in 1800, grew up in the North. In the 1820\u27s he married Mary Ann King of New Jersey: the couple had a single daughter, Rachel Jennie. The Philbricks moved to Charleston, South Carolina in 18J2. By 1836 Daniel was employed as a steamboat captain, carrying goods and passengers on a route which included Augusta, Savannah and Charleston. In 1842 the family came to Savannah, and by 1849 Daniel had acquired real estate and built a spacious home on Washington Square. Both he and his wife were members of the Lutheran Church, and Mary Ann was particularly active in church affairs. Daniel remained a steamboat captain until 1863, when he sold his real estate, realizing a substantial profit, and probably retired. He died in 1B73, his wife in 1886. Their daughter, a writer of modest talent, never married, and so there are no descendants.https://digitalcommons.georgiasouthern.edu/sav-bios-lane/1155/thumbnail.jp

The Attitude of Manitoba High School Principals Toward Physical Education

The purpose of this study was to discover the attitude toward physical education of the one-hundred Manitoba principals of high schools with enrollments over one hundred and fifty. For the basis of evaluation, the Wear Attitude Inventory was incorporated into a questionnaire, to which ninety-one principals responded. Comparisons between different groups of principals to determine attitude differences were also made. These comparisons were made between: Older and younger principals; principals of schools with small enrollment (less than 300) and principals of schools with- larger enrollment; principals with different educational preparation; principals who engaged in personal recreational sports activities and principals who indicated they did not -participate in them; supervisors and non-supervisors; and principals of schools which had a longer class time for physical education and principals of schools with a shorter class time. AS an entire group, the principals had a favorable attitude toward physical education, but the attitude was not highly favorable. No statistically significant attitude differences were found between the different comparison groups

Aerodynamic design for improved manueverability by use of three-dimensional transonic theory

Improvements in transonic maneuver performance by the use of three-dimensional transonic theory and a transonic design procedure were examined. The FLO-27 code of Jameson and Caughey was used to design a new wing for a fighter configuration with lower drag at transonic maneuver conditions. The wing airfoil sections were altered to reduce the upper-surface shock strength by means of a design procedure which is based on the iterative application of the FLO-27 code. The plan form of the fighter configuration was fixed and had a leading edge sweep of 45 deg and an aspect ratio of 3.28. Wind-tunnel tests were conducted on this configuration at Mach numbers from 0.60 to 0.95 and angles of attack from -2 deg to 17 deg. The transonic maneuver performance of this configuration was evaluated by comparison with a wing designed by empirical methods and a wing designed primarily by two-dimensional transonic theory. The configuration designed by the use of FLO-27 had the same or lower drag than the empirical wing and, for some conditions, lower drag than the two-dimensional design. From some maneuver conditions, the drag of the two-dimensional design was somewhat lower
