An AFSCME Local Transforms Local Politics

[Excerpt] In the late 1980s, AFSCME Local 2703, in Merced, California, found itself in a position familiar to many union members at that time: fighting hard to keep pay and benefits from being slashed. The realization that these confrontations could occur at every contract led local members to look for ways to make local government more responsive to the working men and women of the community. Through commitment and determination — and two bitter strikes — Local 2703 held its own against a local government determined to render it powerless. Through community education and coalition, the local to (sic) achieved its first small victories. The lessons the local members learned enabled them to build an effective and influential political action committee that reaches beyond the limits of their own union contracts to pursue political change, furthers community awareness and promote coalitions across racial, ethnic, and economic barriers. Their continuing commitment to the notion that working men and women are brothers and sisters, who deserve the respect of their peers and their government leaders, has them poised to be a visible influence in the politics of Merced County

How to catch a cricket ball

A cricket or baseball fielder can run so as to arrive at just the right place at just the right time to catch a ball. It is shown that if the fielder runs so that d2(tan alpha)/dt2 = 0, where alpha is the angle of elevation of gaze from fielder to ball, then the ball will generally be intercepted before it hits the ground. This is true whatever the aerodynamic drag experienced by the ball. The only exception is if the ball is not approaching the fielder before he starts to run

Lifecycle information for e-literature: a summary from the LIFE project.

The LIFE Project has developed a methodology to calculate the long-term costs and future requirements of the preservation of digital assets. LIFE has achieved this by analysing and comparing three different digital collections and by applying a lifecycle approach to each. From this work LIFE has identified a number of strategic issues and common needs. The critical strategic issues are: •There is a need for a wider collaborative approach between Higher Education (HE) and Libraries to aid in the cost-effective development of tools and methods. •The time required for the realistic development of the next generation of these tools and methodologies is largely unknown and should form part of a collective responsibility within the digital preservation community. •There exists a real opportunity to establish long-term partnerships between institutions to address common requirements. The challenge is to establish multidisciplinary Project teams and programmes to lead these developments. •There exists a real opportunity to establish long-term partnerships between institutions and industry to develop this methodology and to establish new opportunities to share knowledge and experience. The LIFE project could become an important vehicle for the development of these new opportunities

Lifecycle information for e-literature: full report from the LIFE project

This Report is a record of the LIFE Project. The Project has been run for one year and its aim is to deliver crucial information about the cost and management of digital material. This information should then in turn be able to be applied to any institution that has an interest in preserving and providing access to electronic collections. The Project is a joint venture between The British Library and UCL Library Services. The Project is funded by JISC under programme area (i) as listed in paragraph 16 of the JISC 4/04 circular- Institutional Management Support and Collaboration and as such has set requirements and outcomes which must be met and the Project has done its best to do so. Where the Project has been unable to answer specific questions, strong recommendations have been made for future Project work to do so. The outcomes of this Project are expected to be a practical set of guidelines and a framework within which costs can be applied to digital collections in order to answer the following questions: • What is the long term cost of preserving digital material; • Who is going to do it; • What are the long term costs for a library in HE/FE to partner with another institution to carry out long term archiving; • What are the comparative long-term costs of a paper and digital copy of the same publication; • At what point will there be sufficient confidence in the stability and maturity of digital preservation to switch from paper for publications available in parallel formats; • What are the relative risks of digital versus paper archiving. The Project has attempted to answer these questions by using a developing lifecycle methodology and three diverse collections of digital content. The LIFE Project team chose UCL e-journals, BL Web Archiving and the BL VDEP digital collections to provide a strong challenge to the methodology as well as to help reach the key Project aim of attributing long term cost to digital collections. The results from the Case Studies and the Project findings are both surprising and illuminating

Why good thoughts block better ones: The mechanism of the pernicious Einstellung (set) effect.

The Einstellung (set) effect occurs when the first idea that comes to mind, triggered by familiar features of a problem, prevents a better solution being found. It has been shown to affect both people facing novel problems and experts within their field of expertise. We show that it works by influencing mechanisms that determine what information is attended to. Having found one solution, expert chess players reported that they were looking for a better one. But their eye movements showed that they continued to look at features of the problem related to the solution they had already thought of. The mechanism which allows the first schema activated by familiar aspects of a problem to control the subsequent direction of attention may contribute to a wide range of biases both in everyday and expert thought - from confirmation bias in hypothesis testing to the tendency of scientists to ignore results that do not fit their favoured theories

Specialization effect and its influence on memory and problem solving in expert chess players

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong enough to override general expertise – players remembering positions and solving problems from their area of specialization performed at around the level of players one standard deviation above them in general skill. Their problem solving strategy also changed depending on whether the problem was within their area of specialization or not. When it was, they searched more in depth and less in breadth; with problems outside their area of specialization, the reverse. The knowledge that comes from familiarity with a problem area is more important than general purpose strategies in determining how an expert will tackle it. These results demonstrate the link in experts between problem solving and memory of specific experiences and indicate that the search for context independent general purpose problem solving strategies to teach to future experts is unlikely to be successful

Inflexibility of experts – Reality or myth? Quantifying the Einstellung effect in chess masters

How does the knowledge of experts affect their behaviour in situations that require unusual methods of dealing? One possibility, loosely originating in research on creativity and skill acquisition, is that an increase in expertise can lead to inflexibility of thought due to automation of procedures. Yet another possibility, based on expertise research, is that experts’ knowledge leads to flexibility of thought. We tested these two possibilities in a series of experiments using the Einstellung (set) effect paradigm. Chess players tried to solve problems that had both a familiar but non-optimal solution and a better but less familiar one. The more familiar solution induced the Einstellung (set) effect even in experts, preventing them from finding the optimal solution. The presence of the non-optimal solution reduced experts' problem solving ability was reduced to about that of players three standard deviations lower in skill level by the presence of the non-optimal solution. Inflexibility of thought induced by prior knowledge (i.e., the blocking effect of the familiar solution) was shown by experts but the more expert they were, the less prone they were to the effect. Inflexibility of experts is both reality and myth. But the greater the level of expertise, the more of a myth it becomes

NICMOS Observations of Low-Redshift Quasar Host Galaxies

We have obtained Near-Infrared Camera and Multi-Object Spectrometer images of 16 radio quiet quasars observed as part of a project to investigate the ``luminosity/host-mass limit.'' The limit results were presented in McLeod, Rieke, & Storrie-Lombardi (1999). In this paper, we present the images themselves, along with 1- and 2-dimensional analyses of the host galaxy properties. We find that our model-independent 1D technique is reliable for use on ground-based data at low redshifts; that many radio-quiet quasars live in deVaucouleurs-law hosts, although some of the techniques used to determine host type are questionable; that complex structure is found in many of the hosts, but that there are some hosts that are very smooth and symmetric; and that the nuclei radiate at ~2-20% of the Eddington rate based on the assumption that all galaxies have central black holes with a constant mass fraction of 0.6%. Despite targeting hard-to-resolve hosts, we have failed to find any that imply super-Eddington accretion rates.Comment: To appear in ApJ, 28 pages including degraded figures.
