Earth strain measurements with the transportable laser ranging system: Field techniques and planning

The potential of the transportable laser ranging system for monitoring the ground deformation around satellite ranging stations and other geodetic control points was examined with emphasis on testing the usefulness of the relative alteration technique. The temporal variation of the ratio of the length of each survey line to the mean length of all survey lines in a given area is directly related to the mean shear strain rate for the area. The data from a series of experimental measurements taken over the Los Angeles basin from a TLRS station at Mt. Wilson show that such ratios can be determined to an accuracy of one part in 10 million with a measurement program lasting for three days and without using any corrections for variations in atmospheric conditions. A numerical experiment using a set of hypothetical data indicates that reasonable estimates of the present shear strain rate and the direction of the principal axes in southern California can be deduced from such measurements over an interval of one to two years

Lunar seismic data analysis

The scientific data transmitted continuously from all ALSEP (Apollo Lunar Surface Experiment Package) stations on the Moon and recorded on instrumentation tapes at receiving stations distributed around the Earth were processed. The processing produced sets of computer-compatible digital tapes, from which various other data sets convenient for analysis were generated. The seismograms were read, various types of seismic events were classified; the detected events were cataloged

Crustal deformation and seismic measurements in the region of McDonald Observatory, West Texas

The arrival times of regional and local earthquakes and located earthquakes in the Basin and Range province of Texas and in the adjacent areas of Chihuahua, Mexico from January 1976 to August 1980 at the UT'NASA seismic array are summarized. The August 1931 Texas earthquake is reevaluated and the seismicity and crustal structure of West Texas is examined. A table of seismic stations is included

New models of leadership in Kent schools: final report

1. Executive Summary The overall aim of this commissioned project, led by Professor Vivienne Griffiths and Dr Andrew Lambirth at Canterbury Christ Church University, is to identify new models of leadership in Kent schools, their characteristics, benefits and challenges to schools. It builds on recent initiatives in Kent schools as set out by the Advisory Service for Kent (2009), responding to an analysis and identification of school leadership needs (ASK 2008). We were particularly asked to look at: - what schools have learnt from introducing new models of leadership - how they prepared for change - their professional needs in the run up to and during the change process - the barriers to change - the enablers. 1.1 Summary of work undertaken The study involved: a) scrutiny of available data on new models of leadership in Kent schools; b) analysis of the literature and consultation material; c) questionnaires to headteachers of federations (N=19); d) interviews with headteachers of federations (N=16). The interim report presented a description and analysis of the questionnaire responses, which dealt in particular with preparation for change and professional needs during this period of development. In this final report, analysis of the interview data is presented, together with analysis of relevant literature on new models of school leadership. 1.2 Key findings - Origins of federations often focus on the need for a link between stronger and less successful schools, as well as community needs. - Clear vision and aims are expressed, particularly by executive heads. - Federation and community school aims are usually linked to community development. - Federations are usually but not always in deprived communities. - Many federation aims included new buildings and/or a joint federation site. - All federations had joint governing bodies or were moving towards this. Benefits of federations: - Greater support for headteachers - Distributed leadership to senior and middle management - Shared curriculum, within or cross-phase - Sharing of good practice, teaching and pastoral approaches - Shared resources - Joint or semi-joint timetabling - Wider offer of subjects, especially at A-level - Joint CPD, including training for teaching assistants and trainee teachers - Improved standards, attendance and behaviour - Range of benefits to the community. Challenges: - Resistance by staff, parents and governors - Heavy workload, especially for executive heads - Need to change school cultures, especially between selective and non-selective schools - Financial pressures; not necessarily savings - Pressures to raise standards - Federations not generally recognised by Ofsted, so separate inspections. 1.3 Recommendations - Case studies and of successful federations and other new leadership models to be collected. - Dissemination of good practice at headteacher conferences and other events. - Training for executive heads, senior and middle management. - Support groups, ‘buddying’ and mentoring for executive heads and headteachers. - Training for governors, parents and other staff. - Improved communication of aims to staff, governors, parents and pupils. - Further research into the development of federations and other new models of leadership

Testing the proposed link between cosmic rays and cloud cover

A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infra red data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups. The groups went on to hypothesise that the decrease in ionization due to cosmic rays causes the decrease in cloud cover, thereby explaining a large part of the presently observed global warming. We have examined this hypothesis to look for evidence to corroborate it. None has been found and so our conclusions are to doubt it. From the absence of corroborative evidence, we estimate that less than 23%, at the 95% confidence level, of the 11-year cycle change in the globally averaged cloud cover observed in solar cycle 22 is due to the change in the rate of ionization from the solar modulation of cosmic rays
