The Value of a Liberal Arts Education: A Self-Evident Truth

We hold this truth to be self-evident: The best preparation for 21st Century workplace challenges is to earn a liberal arts degree or a professional degree that is grounded in and inspired by the liberal arts

Building the Future - One College Graduate at a Time

The past few weeks have been a time of reflection for me. My father died and my family experienced what all families do when they lose the man who provided for them, guided them, protected them, and — in my case — made sure we fully understood the value of a college education

Higher Ed International Exchange Rate Leaves Intellectual Capital Behind

The higher education “international exchange rate” is unfavorable and improving at an alarmingly slow rate, given our need for graduates prepared for success in our contemporary global economy. There are basically two problems: not enough U.S. students are studying abroad and the opportunity to study abroad is disproportionately available to traditional students enrolled at private institutions

We Should Have High Standards for all Students, Not Just Those at Harvard

After nearly a decade as a chief academic officer, I got used to people asking me my opinion on higher education issues. But now that I am working at the American Council on Education, the questions are more far reaching. For example, recently, someone asked me what I thought should be done about the cheating scandal at Harvard

What You Measure is What You Get Service Learning Can be Cost-Effective Way to Enhance Quality and Student Success

Note: This post connects to the conversational thread started here in March, which focused on sharing lessons and insights about leadership challenges faced by CAOs and other senior administrators as we seek ways to ease the tension between our goals for access, completion rates, and educational quality

Avoid False Dichotomy in Higher Education: Be both Mission-Driven and Market-Smart

Amid all the drama associated with the departure and reinstatement of the UVA President, there remains at least one generic plot line that merits additional analysis: What is the appropriate way to incorporate a business orientation into the ethos of higher education

College Completion: Performance-Based Funding Can Enhance Individual Investments and Promote the Public Good

College completion is both an individual investment and a public good. College graduates can count on higher personal income, better benefit packages, and the likelihood of living a longer, happier life. Our society can count on college graduates to be less violent, to be more economically independent, and to be more tolerant, open minded and civically engaged

Overview of the 2010 Carbonaceous Aerosols and Radiative Effects Study (CARES)

Substantial uncertainties still exist in the scientific understanding of the possible interactions between urban and natural (biogenic) emissions in the production and transformation of atmospheric aerosol and the resulting impact on climate change. The US Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program's Carbonaceous Aerosol and Radiative Effects Study (CARES) carried out in June 2010 in Central Valley, California, was a comprehensive effort designed to improve this understanding. The primary objective of the field study was to investigate the evolution of secondary organic and black carbon aerosols and their climate-related properties in the Sacramento urban plume as it was routinely transported into the forested Sierra Nevada foothills area. Urban aerosols and trace gases experienced significant physical and chemical transformations as they mixed with the reactive biogenic hydrocarbons emitted from the forest. Two heavily-instrumented ground sites – one within the Sacramento urban area and another about 40 km to the northeast in the foothills area – were set up to characterize the evolution of meteorological variables, trace gases, aerosol precursors, aerosol size, composition, and climate-related properties in freshly polluted and "aged" urban air. On selected days, the DOE G-1 aircraft was deployed to make similar measurements upwind and across the evolving Sacramento plume in the morning and again in the afternoon. The NASA B-200 aircraft, carrying remote sensing instruments, was also deployed to characterize the vertical and horizontal distribution of aerosols and aerosol optical properties within and around the plume. This overview provides: (a) the scientific background and motivation for the study, (b) the operational and logistical information pertinent to the execution of the study, (c) an overview of key observations and initial findings from the aircraft and ground-based sampling platforms, and (d) a roadmap of planned data analyses and focused modeling efforts that will facilitate the integration of new knowledge into improved representations of key aerosol processes and properties in climate models.United States.

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
