The information value chain: emerging models for procuring electronic publications

The first part of this paper examines the information supply chain and some of its concepts; particular attention is paid to features differentiating electronic from printed information. The second part discusses the procurement process and, in the light of the analysis made in the first part, evaluates the various models for procuring electronic information

Managing the market place: the consortium approach

engineering approach to atomic transaction verification: use of a simple object model to achieve semantics-based reasoning at compile-time

In this paper, we take an engineering approach to atomic transaction verification. We discuss the design and implementation of a verification tool that can reason about the semantics of atomic database operations. To bridge the gap between language design and automated reasoning, we make use of a simple model of objects that imitates the type-tagged memory structure of an implementation. This simple model is sufficient to describe the operational semantics of the typical features of an object-oriented database programming language, such as bounded iteration, heterogeneity, object creation, and nil values. The same model lends itself to automated reasoning with a theorem prover system. We are thus able to apply theorem prover technology to verification problems that address transaction semantics. The work has applications in the areas of transaction safety, semantics-based concurrency control, and cooperative work. The approach is illustrated by a graph editing example, with heterogeneous node structures

Procuring electronic information: new business models in the context of the supply chain

Examines the information value chain and some of its concepts, first for printed information and second for electronic information. Discusses the procurement process and, in the light of the analysis made earlier in the paper, evaluates the various emerging models for procuring electronic information

Pleasures in Socialism: Leisure and Luxury in the Eastern Bloc

This book is a significant contribution to the studies of everyday life in Eastern Europe under communist rule. It is the third in a series of volumes edited and written with Susan E. Reid, which examine the material culture of the Eastern Bloc: see Style and Socialism (Berg, 2000) and Socialist Spaces (Berg, 2003). Reviewing these titles in the London Review of Books, Sheila Fitzpatrick credits Crowley and Reid as ‘two cultural historians who have played a leading role in the development of studies of the everyday in the former Soviet bloc’. The 14 essays explore how leisure and the consumption of luxury goods formed zones that communist states sought to shape, and thereby to extend the reach of their authority. Yet at the same time, they also presented opportunities for people to assert their individuality and enjoy unlicensed pleasures. This contrasts strongly with the conventional scholarship on the Soviet Bloc, which stresses poverty and repression. Crowley's contribution was to write, with Reid, a 21,000-word critical review of existing debates about leisure and luxury in the Bloc and make a number of propositions about the way in which these concepts and practices need to be further conceptualised and researched. This essay also functions as an introduction to the book. The origins of the book lie in a conference organised by Crowley and Reid at the V&A Museum in London in 2007. Following publication, Crowley was invited to talk about the themes in this volume at Södertörn University, Centre for Baltic and East European Studies in Stockholm (2012). A review of this book was published in Slavic Review (2011). Crowley and Reid were also interviewed about the volume in an hour-long podcast for New Books in Eastern Europe Studies (2012)

Characterization of interstitial stem cells in hydra by cloning

A procedure has been developed for cloning interstitial stem cells from hydra. Clones are prepared by introducing small numbers of viable cells into aggregates of nitrogen mustard-inactivated host tissue. Clones derived from added stem cells are identified after 1–2 weeks of growth by staining with toluidine blue. The incidence of clones increases with increasing input of viable cells according to one-hit Poisson statistics, indicating that clones arise from single cells. After correction for cell losses in the procedure, about 1.2% of the input cells are found to form clones. This compares with estimates from in vivo experiments of about 4% stem cells in whole hydra [David, C. N., and Gierer, A. (1974). Cell cycle kinetics and development of Hydra attenuata. III. Nerve and nematocyte differentiation. J. Cell Sci. 16, 359–375.] Differentiation of nematocytes and nerve cells in clones was analyzed by labeling precursors with [3H]thymidine and scoring labeled nerves and nematocytes 2 days later. Nine clones examined in this way contained both differentiated nerve cells and nematocytes, demonstrating that the interstitial stem cell is multipotent. This result suggests that the observed localization of nerve and nematocyte differentiation in whole hydra probably occurs at the level of stemcell determination. The observation that differentiated cells occur very early in clone development suggests that a stem cell's decision to proliferate or differentiate is regulated by shortrange feedback signals which are already saturated in young clones

Geological Mapping of the Debussy Quadrangle (H-14) - Preliminary Results

Geological mapping of Mercury is essential to build an understanding of the history of the planet and to set the context for observations by BepiColombo [1]. Geological mapping of the Debussy quadrangle (H-14) is now underway as part of a program to map the entire planet at a scale of 1:3M using MESSENGER data [2]. The quadrangle is located in the southern hemisphere of Mercury at 0o – 90o E and 22.5o – 65o S. This will be the first high resolution map of the quadrangle as it was not previously imaged by Mariner 10

Temporary Agency Employment as a Way out of Poverty?

The high incidence of temporary agency employment among participants in government employment programs has catalyzed debate about whether these jobs help the poor transition into stable employment and out of poverty. We provide direct evidence on this question through analysis of a Michigan welfare-to-work program in which program participants were randomly allocated across service providers (‘contractors') with different job placement practices. We draw on a telephone survey of contractors and on administrative program data linked with wage records data on all participants entering the program over a three-and-a half-year period. Our survey evidence documents a consensus among contractors that temporary help jobs are generally easier for those with weak skills and experience to obtain, but no consensus on whether temporary help jobs confer long-term benefits to participants. Our analysis of the quasi- experimental data introduced in Autor and Houseman (2005) shows that placing participants in either temporary or direct-hire jobs improves their odds of leaving welfare and escaping poverty in the short term. However, we find that only direct-hire placements help reduce welfare dependency over longer time horizons. Our findings raise questions about the incentive structure of many government employment programs that emphasize rapid placement of program participants into jobs and that may inadvertently encourage high placement rates with temporary help agencies.temporary agency, poverty, welfare, welfare-to-work, autor, houseman
