Appendix A. Technical Notes

 

During the production of this report, the America COMPETES Reauthorization Act of 2010 was signed into law. Section 505 of the bill renames the Division of Science Resources Statistics as the National Center for Science and Engineering Statistics (NCSES). The Center retains its reporting line to the Directorate for Social, Behavioral, and Economic Sciences within the National Science Foundation. The new name signals the central role of NCSES in the collection, interpretation, analysis, and dissemination of objective data on the science and engineering enterprise.

Scope of Survey

The data presented in these tables are collected biennially through the National Science Foundation's (NSF's) congressionally mandated Survey of Science and Engineering Research Facilities (Facilities Survey). The survey originated in 1986 in response to Congress's concern about the state of research facilities at the nation's colleges and universities. NSF's 1984 reauthorization legislation, P.L. 99–159, mandated a data collection and analytic system to identify and assess the research facilities needs of academic institutions. The National Institutes of Health (NIH) has cosponsored all cycles of the survey.

Recognizing the growing use of networking and computing capacity in conducting research, the NSF added a new set of questions on these topics to the FY 2003 Facilities Survey, and these questions were revised for the FY 2005 and FY 2007 surveys.

Population

The FY 2007 population consisted of 489 research-performing academic institutions and 188 nonprofit biomedical research institutions in the United States. Research-performing academic institutions were defined as colleges and universities with $1 million or more in research and development expenditures. Each academic institution's level of R&D expenditures was determined by the FY 2006 NSF Survey of Research and Development Expenditures at Universities and Colleges. Military institutions, Veterans Administration institutions, and federally funded research and development centers were excluded. The biomedical institution frame was a list of nonprofit biomedical research organizations and hospitals in the United States that received at least $1 million in NIH research funding in FY 2005.

Changes from the Previous Cycle

The survey questions on the Computing and Networking section of the survey are significantly revised each survey cycle to reflect new topics of interest and/or advances in technology. In addition, the following changes were made:

  • The fields of science and engineering (S&E) were updated to reflect the National Center for Education Statistics (NCES) 2000 Classification of Instructional Programs. Tables 3, 4, 40, 41, 59, and 60 display S&E fields as collected prior to FY 2007. These data may not be comparable to data collected by field in FY 2007 and later years.
  • The definition of medical school was expanded to include schools that award the doctor of osteopathic medicine (DO) degree.
  • Deferred projects are now limited to projects estimated to be $250,000 or more for at least one field of S&E.
  • Questions on high-performance computing (HPC) architectures and their associated storage were added.
  • The questions on leased space, maximum speed of any Internet connection, and the number and availability of high performance computing were deleted.

Historical Changes and Data Comparability

Since these data were first collected in 1986, changes have been made to the population, the sample, and the survey questions.

FY 2005

  • A process was instituted whereby at the end of each data collection, new construction data are analyzed for instances of double counting. See "Comparability of Statistics," in appendix A of NSF publication Science and Engineering Research Facilities: FY 2005, for more detail. When necessary the previous survey cycle's new construction data are revised in the current year's detailed statistical tables.
  • Discovery of duplications in the reporting of new construction projects resulted in revisions to FY 2003 data related to new construction and source of funding for new construction. Data shown in the FY 2005 tables reflect the revised data.
  • Research space was not broken out by categories of space: laboratory, laboratory support, offices, and other research space.
  • Research animal space was no longer broken out into housing and laboratory space.
  • Questions on indirect costs from federal grants/contracts were deleted.
  • Questions on the Computing and Networking section of the survey were significantly revised. Most of the FY 2003 questions were replaced with more current questions to reflecting changing technology. However, the topics covered in the section generally remained the same (e.g., networking, high-performance computing, wireless coverage).

FY 2003

  • The survey used an extensively redesigned questionnaire. Questions asking about all medical school data replaced questions about biological sciences and medical sciences inside or outside a medical school. A new section on networking and computing capacity was added. To the extent possible, the survey was redesigned for comparability over time. A more comprehensive description of the redesigned survey can be found in Redesign of Survey of Science and Engineering Research Facilities: 2003.
  • Research space was broken out by categories of space: laboratory, laboratory support, offices, and other research space.
  • The threshold for reporting repair and renovation and construction projects was raised from $100,000 to $250,000.
  • The definition of research-performing institutions was changed to institutions having at least $1 million in R&D expenditures or as having received at least $1 million in NIH funding. In FY 2001 the minimum threshold for both types of institutions was $150,000.

FY 2001

  • Only questions one and two of the prior surveys were asked.

FY 1999

  • The minimum level of R&D expenditures for eligible research-performing academic institutions was increased from institutions with at least $50,000 in R&D expenditures to institutions with at least $150,000 in R&D expenditures (except HBCUs). For biomedical organizations the minimum level in NIH funding received increased from at least $50,000 to at least $150,000 in funding.
  • A census of eligible institutions was surveyed. In prior years, eligible institutions were sampled using a stratified sampling design.
  • The animal research facilities survey questions changed over survey cycles to correspond to the changes in the issues associated with animal research facilities. For the 1999 cycle, most of the animal research facilities questions were modeled after the general S&E survey questions regarding the amount of space, the condition of space, the new construction and repair/renovation of space; and the costs of new construction and repair/renovation.

Analytic Definitions

Several analytic subgroups are presented in the table data. These subgroups are defined as follows:

Geographic regions. States and the District of Columbia may be divided into the four U.S. geographic regions defined by the U.S. Census Bureau. These are categorized as follows:

  • Northeast: CT, ME, MA, NH, NJ, NY, PA, RI, VT
  • Midwest: IL, IN, IA, KS, MI, MN, MO, NE, ND, OH, SD,WI
  • South: AL, AR, DE, DC, FL, GA, KY, LA, MD, MS, NC, OK, SC, TN, TX, VA, WV
  • West: AK, AZ, CA, CO, HI, ID, MT, NV, NM, OR, UT, WA, WY

Guam, Puerto Rico, and the U.S. Virgin Islands are excluded from the geographic regions but are included in the national statistics and other appropriate aggregate figures.

EPSCoR. States may be grouped according to their eligibility for NSF funding. States are eligible for the NSF Experimental Program to Stimulate Competitive Research (EPSCoR) if they have historically received less federal R&D funding than other states. The purpose of the program is to increase the R&D funding competitiveness of these states by assisting in the development and utilization of science and technology resources. The following states are currently eligible for this program:

  • AL, AK, AR, DE, HI, ID, KS, KY, LA, ME, MS, MT, NH, NM, NE, NV, ND, OK, RI, SC, SD, TN, VT, WV, WY, U.S. Virgin Islands, and Puerto Rico

IDeA. NIH sponsors the Institutional Development Award (IDeA) program. This program was established in 1993 in order to enhance the competitiveness for research funding of institutions located in states with historically low aggregate success rates for NIH grant applications. The goal is to broaden the geographic distribution of NIH funding for health research. The following states are currently eligible for this program:

  • AK, AR, DE, HI, ID, KS, KY, LA, ME, MS, MT, NH, NM, NE, NV, ND, OK, RI, SC, SD, VT, WV, WY, and Puerto Rico

Institutional control is defined for academic institutions as private or public.

Medical school is a school that awards a doctor of medicine degree or a DO degree.

Response Rate

The FY 2007 Facilities Survey was mailed to academic and biomedical institutions in October 2007, and data collection ended in August 2008. Of the 489 academic institutions, 92% returned surveys. Of the 188 biomedical organizations, 87% returned surveys. The overall response rate was 90%.

Weighting

The FY 2007 Facilities Survey attempted to obtain responses from all institutions in the defined population. Consequently one of the usual sources of survey error, sampling error, is not of concern in this survey. However, as is the case in almost all surveys, nonresponse error is of concern. In the FY 2007 Facilities Survey, 90% of all eligible institutions responded.

Weights were used to account for unit nonresponse. The weights for the academic institutions were adjusted for the known number of academic institutions by expenditure categories (the quintiles of the distribution), census region, institutional control (public or private), and whether the institution granted doctor of philosophy degrees. The weights for the biomedical institutions were adjusted for the known number of biomedical institutions by the grant amount (quintiles of the distribution). The minimum weights for both academic and biomedical institutions were constrained to be at least 1.0.

The FY 2007 Facilities Survey Detailed Statistical Tables contain two sets of data. Tables 1–72 in this report display data collected by part 1 of the survey (research space). Data in those tables are weighted according to the previously described procedures, except for the data on condition of research space and the data presented by state (i.e., tables 10, 11, 17, 18, 21, 22, 30, 31, 34, 35, 38, 39, 49, 50, 53, 54, 57, and 58). Tables 73–92 of this report display data collected by part 2 of the survey (computing and networking). The data collected by part 2 of the survey are not weighted due to potential measurement error within the survey responses. It is believed that substantially greater measurement error may exist in the computing and networking data because of the rapidly changing nature and variability of this data. Likewise, item nonresponse is not imputed for questions relating to computing and networking.

Item Nonresponse

A series of logistic regression models and linear regression models were developed and used to impute the values for all missing data for institutions that responded to the survey. The predicted values from these models were used to impute for the missing responses. The imputation for academic and biomedical data was completed separately. The models for imputing the academic data were developed first, and similar models were then applied to impute the biomedical data, to the extent possible.

A set of core predictors was used for imputing most items across the two types of institutions, but differences in the available data by type of institution limited this process to some degree. For academic institutions, the core predictors were institutional control (public or private), highest degree granted (doctorate or nondoctorate), existence of a medical school, FY 2006 total R&D expenditures (overall), and total net assignable square feet (NASF). For biomedical institutions, the core predictors were status as a hospital or other biomedical institution, FY 2005 eligible NIH grant awards, and total NASF. In addition to the core predictors, regression models for specific survey items included data from responses to other survey items.

Tables showing data by state and control (i.e., public versus private) and individual institution tables are based on unimputed data.

Comparability of Statistics

This section summarizes major survey improvements and changes in procedures and practices that may have affected the comparability of statistics produced from the Facilities Survey over time.

Beginning with the FY 2003 cycle and continuing with the FY 2005 and FY 2007 cycles, respondents were requested to provide data on their institution's individual, new construction projects. Respondents provided several types of data for each project, including name, gross square feet, NASF, and cost of project. Using this information, it was possible to compare the new construction projects reported by each institution in FY 2005 with the projects that the same institution reported in FY 2007 to determine whether any appeared to be duplicates.

This comparison identified 20 projects with the same or similar characteristics. Contact with the relevant institutions indicated that the status of five projects needed to be updated from the FY 2005 survey. With the approval of each institution, these projects were deleted from their FY 2005 new construction data.

Also, the data on the source of funding for new construction projects was revised to reflect the deletion of these projects. The five new construction projects that were removed from the FY 2005 data affected the records of five institutions. For four institutions, the removal eliminated all new construction projects reported; as a result, all funds reported by source for new construction were also deleted.

For the remaining institution, one other reported construction project remained. Costs associated with the deleted projects(s) were subtracted from the sources of funds total for the institution. The remaining funds were reallocated to source by distributing the remaining funds across sources indicated using the same allocation that had been initially reported by the institution.

Data Definitions

Research is all sponsored science and engineering R&D activities that are separately budgeted and accounted for. Research can be funded by the institution itself, the federal government, a state government, foundations, corporations, or other sources. It does not include departmental research that is not separately budgeted.

Research space includes the following examples: controlled-environment space, such as clean or white rooms; technical support space, such as preparation areas and carpentry and machine shops; laboratories, including computer laboratories and behavior observation rooms; core laboratories that serve other laboratories; laboratories and associated support areas used for animal research, including procedure rooms, bench space, animal production colonies, holding rooms, germ-free rooms, surgical facilities, and recovery rooms; space for clinical trial research; offices, to the extent that they are used for research activities including administrative activities for specific research projects; space with fixed (built-in) equipment, such as fume hoods; space with nonfixed equipment costing $1 million or more each, such as MRIs; and leased space that is used for research.

Net assignable square feet (NASF) is the sum of all areas on all floors of a building assigned to, or available to be assigned to, an occupant for a specific use, such as research or instruction. NASF is measured from the inside faces of walls.

Gross square feet is based on the floor area of a structure within the outside faces of the exterior walls.

Biosafety level (BL) designates a typology of animal research and is measured at four levels: BL-1 involves working with defined and characterized strains of viable microorganisms not known to cause disease in healthy adult humans; BL-2 involves working with the broad spectrum of indigenous moderate-risk agents present in the community and associated with human disease of varying severity; BL-3 involves working with indigenous or exotic agents with a potential for respiratory transmission and that may cause serious and potentially lethal infection; and BL-4 involves working with dangerous and exotic agents that pose a high individual risk of life threatening disease, that may be transmitted via the aerosol route, and for which there is no available vaccine or therapy.

Repairs and renovations refer to activities such as fixing up facilities in deteriorated condition, capital improvements on facilities, conversion of facilities, and the building out of shell space.

New construction refers to construction of a new building or additions to an existing building.

Completion costs include those for planning, site preparation, construction, fixed equipment, and building infrastructure, such as plumbing, lighting, air exchange, and safety systems either in the building or within 5 feet of the building foundation. Costs of nonfixed equipment are included only if they equal or exceed $1 million.

Institutional funds and other sources include the following examples: operating funds, endowments, tax-exempt bonds and other debt financing, indirect costs recovered from federal grants or contracts, and private donations.

Current program commitments are all research activities of an institution that are budgeted, approved, and funded. They include current faculty and staff or those to whom offers have been made; grants awarded, whether research has actually begun; and programs that have been approved.

Deferred projects are those that (1) are not funded and (2) are not scheduled for FY 2006 or FY 2007. They do not include projects planned for developing new programs or expanding current programs. Deferred projects are limited to only those projects whose prorated cost was estimated to be $250,000 or more for at least one field of S&E.

Bandwidth is the amount of data that can be transmitted in a given amount of time, usually measured in bits per second.

Commodity Internet is the general public, multiuse network often called the "Internet."

Abilene is a high-performance backbone network managed by the Internet2 consortium of academia, industry, and government.

Desktop ports are connections among individual personal computers or workstations and the local area network or campus backbone.

Centrally administered high-performance computing (HPC) is computing of teraflop or more managed by a distinct organizational unit with a staff and a budget; the unit has a stated mission that includes supporting the HPC needs of faculty and researchers.
