External and Internal Influences on Institutional Approaches to Student Assessment: Accountability or Improvement?
The purpose of this study is to compare the influences of state characteristics related to student assessment, accreditation emphasis on student assessment, and institutional dynamics supporting student assessment on the approaches to student assessment that institutions have initiated. We conducted this study by examining the relevant literature, creating a national survey instrument, surveying undergraduate institutions throughout the United States, and analyzing the responses of the 885 public institutions who participated in our survey. Separate regressions were run for three different groups of institutional types on three approaches to assessment: cognitive, affective, and post-college. Regressions for the three institutional types explained 21 to 27% of the variance for cognitive assessment, 7 to 21% for affective assessment and 6 to 19% for post-college assessment. With the exception of a minor influence of state characteristics for doctoral and research universities, institutional dynamics and accreditation region were found to be the primary influences on student assessment approaches for all institutional types. We found that the drive for state-level accountability has not exceeded the influence of institutional accreditation and that internal dynamics appear to be the driving force of all three approaches to student assessment.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43623/1/11162_2004_Article_223326.pd
Organizational Practices Enhancing the Influence of Student Assessment Information in Academic Decisions
Student assessment should not be undertaken as an end in itself but as a means to educational and institutional improvement. The purpose of our study is to provide systematic empirical evidence of how postsecondary institutions support and promote the use of student assessment information in academic decision making. We use linear regression to determine which institutional variables are related to whether student assessment data is influential in academic decisions. Our conclusion is that student assessment data has only a marginal influence on academic decision making. Our data show there is slightly more influence on educationally related decisions than on faculty-related decisions, but in neither case is student assessment data very influential. Nonetheless, we did find several significant predictor variables in our model, including: the number of institutional studies relating students' performance to their interactions with the institution; conducting student assessment to improve internal institutional performance; involving student affairs personnel in student assessment; the extent of student assessment conducted; and the extent of professional development related to student assessment that is offered to faculty, staff, and administrators. These findings vary by institutional type.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43622/1/11162_2004_Article_221314.pd
Factors That Promote Faculty Involvement in and Satisfaction with Institutional and Classroom Student Assessment
This study examines institutional factors that promote faculty satisfaction with their institution's approach to and support for student assessment and that are related to faculty involvement in their institution's support practices and in their own engagement with student assessment in the classroom. The study is based on a survey of faculty from 7 institutions that vary by type, control, and accrediting region. The institution's student assessment purposes, its administrative support patterns, and its faculty instructional impacts are significant predictors of faculty satisfaction with their institution's approach to and support for student assessment. External influences on, faculty uses, and perceived benefits of professional development practices for student assessment are significant predictors of faculty involvement with student assessment in their institution and their classes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43629/1/11162_2004_Article_456126.pd
Faculty and administrator perceptions of their environments: Different views or different models of organization?
Individuals' perceptions of the culture and climate of the organizations in which they work influence their motivation and individual performance. Using a theoretical model of institutional culture, organizational climate, and faculty motivation, this study examines how faculty and academic administrators differ in their perceptions; whether these differences in perceptions are affected by institutional type; and to what extent faculty and administrators have different implicit models of their institutions (i.e., see different organizational variables as predictors of faculty motivation and involvement). The goals of this investigation are to shed additional light on the relationship between institutional variables and faculty performance, to examine the existence of differing implicit models, and to provide new insights for administrators in managing their postsecondary institutions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43609/1/11162_2004_Article_BF00973578.pd
Comparing Union and Nonunion Staff Perceptions of the Higher Education Work Environment
Evidence of substantial growth in unionization among university noninstructional staff over the past 20 years (Hurd and Woodhead, 1987) and the emergence of a quality movement in higher education linking employee attitudes toward the work environment with increased productivity point to the need for additional research into union and nonunion staff perceptions of the work environment. This paper describes a conceptually oriented, exploratory study of the university work environment as perceived and defined by union and nonunion noninstructional staff.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43620/1/11162_2004_Article_423996.pd

The impact of a chief planning officer on the administrative environment for planning
Institution-wide planning, to be effective, must have the support of key administrators. Presidents, vice-presidents, deans, and directors must feel that sufficient consensus can be reached on explicit goals to make comprehensive planning possible and worthwhile. While much has been written about the importance of CEO leadership in gaining broad support for planning, little has been said about the role of the chief planning officer in this regard. This paper, based on a national survey of administrators' views of planning, studies the relationship between having a chief planning officer and administrators' perceptions of campus planning. Its intended audience includes all those interested in institutional planning.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43608/1/11162_2004_Article_BF00991968.pd

the new experimental information on the dependence of . Careful
attention is paid to the experimental and theoretical uncertainties. The data
constrain the first moments of the polarized valence quark distributions, but
only qualitatively constrain the polarized sea quark and gluon distributions.
The NLO results are used to determine the dependence of the ratio

Large expert-curated database for benchmarking document similarity detection in biomedical literature search
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
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
