Working with graphic design students to promote `Land of Lost ContentÂż at Leeds Met.
yesAs Leeds Metropolitan is a university of festivals
and partnerships, the library was given the opportunity
this year to host a festival to promote the
library and all its services to the university. The
library festival was a week of events and activities
to promote the library and its space in new ways.
It was a good way to remind staff and students of
the value of libraries, not only as places to learn
but also as places to enhance our leisure and
working lives ... we chose to promote the database `Land of Lost
ContentÂż. This was because graphic design and
art students are based at our campus and we also
thought this database would attract a wide range
of students who might otherwise think that electronic
databases contain little of interest for them.
Our promotion has been so successful in many
ways that we would like to share our experience
with other librarians
Darwinian transformation of a 'scarcely nutritious fluid' into milk
In an early challenge to an aspect of Darwinâs theory of natural selection, Jackson Mivart contended that milk could not have evolved âfrom a scarcely nutritious fluid from an accidentally hypertrophied cutaneous glandâ. The evolutionary change from a gland secretion to milk involves an increase in calcium and protein concentrations by up to 100- and 1000-fold, respectively. Even so, the challenge, we suggest, is not just a problem of scale. An increase in the concentrations of calcium and phosphate brings an increased risk of calcification of the secretory gland because calcium phosphate is highly insoluble. In addition, two of the four constituent milk casein proteins (Îș and αS2) aggregate to produce toxic amyloid fibrils. It is proposed that both problems were solved through the cosecretion of ancestral ÎČ- and Îș-caseins to form a stable amorphous aggregate of both proteins with sequestered amorphous calcium phosphate, that is, a primordial casein micelle. Evolutionarily, a gradual increase in the concentration of casein micelles could therefore produce progressively more nutritious fluids for the neonate without endangering the reproductive potential of the mother
SAR antenna calibration techniques
Calibration of SAR antennas requires a measurement of gain, elevation and azimuth pattern shape, boresight error, cross-polarization levels, and phase vs. angle and frequency. For spaceborne SAR antennas of SEASAT size operating at C-band or higher, some of these measurements can become extremely difficult using conventional far-field antenna test ranges. Near-field scanning techniques offer an alternative approach and for C-band or X-band SARs, give much improved accuracy and precision as compared to that obtainable with a far-field approach
Impacts of the Fair and Equitable Tobacco Reform Act of 2004 on Shareholdersâ Wealth in the Tobacco Industry
This study examines the impact and efficiency of the design of the Fair and Equitable Tobacco Reform Act of 2004 in deregulating the tobacco production industry. Results offer a number of policy implications of which deregulation of an economically challenged industry can be achieved without the use of taxpayer funds.Tobacco Buyout, Tobacco Industry, Event Study, Agribusiness, Agricultural and Food Policy,
Investigation of individual factors impacting the effectiveness of requirements inspections: a replicated experiment
Cataloged from PDF version of article.This paper presents a replication of an empirical study regarding the impact of
individual factors on the effectiveness of requirements inspections. Experimental replications
are important for verifying results and investigating the generality of empirical studies.
We utilized the lab package and procedures from the original study, with some changes and
additions, to conduct the replication with 69 professional developers in three different
companies in Turkey. In general the results of the replication were consistent with those of
the original study. The main result from the original study, which is supported in the
replication, was that inspectors whose degree is in a field related to software engineering
are less effective during a requirements inspection than inspectors whose degrees are in other
fields. In addition, we found that Company, Experience, and English Proficiency impacted
inspection effectiveness
