Lisvane's legacy? Constitutional reform in the Isle of Man
The Isle of Man is a largely autonomous dependent territory of the UK. In 2016, Lord Lisvane was commissioned to report on the functioning of the principal organ of governance, the Tynwald. This Lisvane Review has led to substantial constitutional reform within this small democracy, particularly in relation to the unelected second chamber of Tynwald, the Legislative Council. This reflects an ancient tension within the Manx constitution between the House of Keys, since the mid-nineteenth century a directly elected chamber, and the unelected Legislative Council. The Lisvane period saw important changes to the composition and powers of the Legislative Council, as well as gender diversity within Tynwald as a whole. Placing the Manx experience within a broader small democracy theoretical and comparative framework demonstrates not only the possibility of constitutional reform, but also provides insights into resources for constitutional development, the special challenges of managing intimacy, and the dangers of over-concentration of power in a small democracy
EDUCATION OVER THE INTERNET
The global network of computers, called the Internet, offers special challenges and opportunities to educators for delivering educational programs. The opportunity of education over the Internet has been recognized almost since an interconnected network of computers was conceived. However, access to the Internet by the general public has been low; in 1995 only 4-6% of the people in the U.S. have access. Nevertheless, access has been expanding rapidly, and with the advent of the $500 network computer, is expected to increase substantially over the next few years. Information available over the Internet is also expanding rapidly. In March 1996, the Megellan search engine returned just over 13,000 hits for the keyword wildlife. Just 3 months later, in June 1996, the same search returned almost 19,000 hits—a 46% increase. The same search engine returned approximately 32,000 hits for the keywords endangered species. Thus, there is lots of information already available on the Internet concerning fisheries and wildlife. The Internet may be particularly relevant to extension education because people searching for information or educational programs over the Internet fit the model of helping people help themselves. The purpose of this paper is to examine (1) some of the forms of Internet education, and (2) some of the issues related to educating over the Internet. I would like to acknowledge Ken Kingsley for several of the ideas presented in this paper. I would also like to point out that I am far from an expert on this topic; I would characterize myself as a user who could not find anyone appropriate to put these thoughts together
Discovery of a Large-scale Wall in the Direction of Abell 22
We report on the discovery of a large-scale wall in the direction of Abell
22. Using photometric and spectroscopic data from the Las Campanas Observatory
and Anglo-Australian Telescope Rich Cluster Survey, Abell 22 is found to
exhibit a highly unusual and striking redshift distribution. We show that Abell
22 exhibits a foreground wall-like structure by examining the galaxy
distributions in both redshift space and on the colour-magnitude plane. A
search for other galaxies and clusters in the nearby region using the 2dF
Galaxy Redshift Survey database suggests that the wall-like structure is a
significant large-scale, non-virialized filament which runs between two other
Abell clusters either side of Abell 22. The filament stretches over at least
>40 Mpc in length and 10 Mpc in width at the redshift of Abell 22.Comment: 6 pages, 4 figures, accepted for publication in MNRAS letter
AX J0049.4-7323 - a close look at a neutron star interacting with a circumstellar disk
Detailed evidence on the system AX J0049.4-7323 is presented here to show how
the passage of the neutron star in the binary system disrupts the circumstellar
disk of the mass donor Be star. A similar effect is noted in three other
Be/X-ray binary systems. Together the observational data should provide
valuable tools for modelling these complex interactions.Comment: 4 pages, accepted for publication in MNRA
Evaluation of Ultrasonic Velocity Tests to Characterize Extraterrestrial Rock Masses
This thesis investigates the use of ultrasonic pulse velocity (UPV) tests for extraterrestrial rock characterization by evaluating the effects of physical sample properties on the signal attenuation of ultrasonic waves. An initial review of standard laboratory UPV testing methods and expected space conditions isolated four key disparities between the two testing environments: (1) sample dimensions, (2) regolith cover, (3) sample surface roughness, and (4) utility of a gel couplant. Laboratory tests were then performed to assess the influence of these parameters in simulated space conditions, using concrete beams to simulate large sample sizes, and ground limestone to simulate regolith cover. The ensuing data analysis identified strategies to ensure adequate signal transmission and data interpretation.;Overall, the experimental results show that the signal attenuation curves can be constructed and simple regression curves can provide estimations of the true P-wave velocity even without a gel couplant. For the case of large sample sizes, simple exponential regression of the measured P-wave velocity at various transmission lengths can be extrapolated to zero length to estimate the true value. For the case of regolith cover, the particle top size and particle size distribution affect signal attenuation; however, an exponential fit to measured velocity versus depth data can be used to accurately predict true sample velocity at zero depth. Additionally, testing with rough samples showed that compacted regolith can be used to ensure contact between the sample and the UPV transmitter, and this method produced similar attenuation curves to those determined from smooth samples. Altogether, these data indicate the reliability of UPV to characterize material in-situ; however, without a gel couplant, UPV measurements become increasingly imprecise.

The work of a religious representative in a democratic legislature: A case study of the Lord Bishop of Sodor and Man in Tynwald, 1961-2001
The Isle of Man is a largely autonomous territory of the United Kingdom Crown, whose dominant constitutional body is the Tynwald. Tynwald, although meeting regularly as a single body, is for most purposes divided into two Branches – a directly elected House of Keys, and the Legislative Council. The latter includes among its members the Lord Bishop of Sodor and Man. This study draws upon the legislative debates of Tynwald between 1961 and 2001 to examine the nature of the Bishop’s role. Analysis shows that the Bishop was expected to contribute to debate in two major areas – moral issues and technical issues concerning the Manx Church. Additionally, the Bishops operated within expectations as to their modes of contribution. The strongest of these was that the Bishop should not become entangled in party politics. There was also a strong expectation that the Bishop should represent the Manx Church and Christianity more generally, although this expectation does not seem to have been realised in relation to non-Christian religions. There is also evidence that the Bishop was also entitled to use both secular and religious modes of argumentation, and that he should not have expected to the be the only religious voice in Tynwald, or even the uncontested voice of the Manx Church
