The pilot study.

Abstract: This pilot aims to better understand the market for childcare in Saudi Arabia – both the supply and demand sides – and to design a randomized controlled experiment to test whether access to affordable day care (in the form of subsidies, for example) would incentivize Saudi mothers to search actively for employment and to remain employed once they are hired. In addition, the study seeks to understand the degree to which employment early on in one’s life impacts employment in later stages. The pilot will provide information on the groups of women the experiment should target, appropriate levels for the childcare subsidy, and the quality and current geographic locations of daycare sites. Expected Impact Determine the effects of facilitating childcare access on Saudi women’s employment.

The psychology of attitudes.

Abstract: This is the only truly comprehensive advanced level textbook in the past 20 years designed for courses in the pscyhology of attitudes and related studies in attitude measurement, social cognition. Written by two of the most distinguished scholars in the field, its comprehensive coverage of classic and modern research and theory is unsurpassed.

Construction of Escherichia coli K-12 in-frame, single-gene knockout mutants: the Keio collection.

Abstract: We have systematically made a set of precisely defined, single-gene deletions of all nonessential genes in Escherichia coli K-12. Open-reading frame coding regions were replaced with a kanamycin cassette flanked by FLP recognition target sites by using a one-step method for inactivation of chromosomal genes and primers designed to create in-frame deletions upon excision of the resistance cassette. Of 4288 genes targeted, mutants were obtained for 3985. To alleviate problems encountered in high-throughput studies, two independent mutants were saved for every deleted gene. These mutants-the 'Keio collection'-provide a new resource not only for systematic analyses of unknown gene functions and gene regulatory networks but also for genome-wide testing of mutational effects in a common strain background, E. coli K-12 BW25113. We were unable to disrupt 303 genes, including 37 of unknown function, which are candidates for essential genes. Distribution is being handled via GenoBase (http://ecoli.aist-nara.ac.jp/).

Evaluation, Treatment, and Prevention of Vitamin D Deficiency: an Endocrine Society Clinical Practice Guideline

Abstract: Objective: The objective was to provide guidelines to clinicians for the evaluation, treatment, and prevention of vitamin D deficiency with an emphasis on the care of patients who are at risk for deficiency. Participants: The Task Force was composed of a Chair, six additional experts, and a methodologist. The Task Force received no corporate funding or remuneration. Consensus Process: Consensus was guided by systematic reviews of evidence and discussions during several conference calls and e-mail communications. The draft prepared by the Task Force was reviewed successively by The Endocrine Society's Clinical Guidelines Subcommittee, Clinical Affairs Core Committee, and cosponsoring associations, and it was posted on The Endocrine Society web site for member review. At each stage of review, the Task Force received written comments and incorporated needed changes. Conclusions: Considering that vitamin D deficiency is very common in all age groups and that few foods contain vitamin D, the Task Force recomme...
