Over the past nine years ending in 2017, an average of 13 percent or one in eight students who started college in any fall term transferred to a different institution by the following fall. This group also showed the highest spread between persistence and retention rates, with about 15 percent, or one in seven students, enrolling in a different institution in their second fall term. The following sample from a Percentiles The term percentile designates a citation threshold at or above that at which a fixed fraction of the papers fall. In contrast, publications in some countries have higher total citations, but publications have lower average citations. The report does not reveal how many citations are from any single year between 2008 and the present. This group also showed the highest spread between persistence and retention rates, with about 15 percent, or one in seven students, enrolling in a different institution in their second fall term. The smaller the percentile, the higher the minimum number of citations. Citations per paper investigations have normally used statistical regression to assess whether gender helps to explain citation rates, taking a range of other variables Perhaps such a tightly focussed measure might be illustrative elsewhere however, we have noted other serious problems found with bibliometric measures, particularly in the United Kingdom. The NRC is a subsidiary body of the National Academy of Sciences, which is a private, non-profit body, with a mandate to advise the federal government on science and technology issues. White students had the highest share continuing college in fall 2018 at an institution other than the starting institution (15.1 percent). The European nations of Ireland (86.10), Belgium (46.21), and Spain (46.21) are in top place in terms of average citations per document (37.67). Among students who for the first time entered college at four-year private nonprofit institutions in fall 2017, white and Asian students had similar first-year persistence rates (89.4 percent and 90.7 percent, respectively), but Asian students were more likely to continue college at their starting institution (82.5 percent compared to 75.1 percent for white students). Table7.1. Among all students who enrolled in college for the first time in fall 2017, 73.8 percent persisted at any U.S. institution in fall 2018, while 61.7 percent were retained at their starting institution. Full ICMJE author disclosure forms are available for this article online, as supplementary material. First, in general, the average Altmetric score of cover papers was higher than that of non-cover papers. Liberal Arts, Humanities, and General Studies had a higher transfer-out rate (11.4 percent), consistent with the fact that these majors are often designed to prepare students for transfer to four-year institutions. A feature of Google Scholar is Google Scholar Citations which allows users to create a personal publication profile which allows for generation of citation reports. For students who started college in fall 2017 at four-year private nonprofit institutions, the persistence rate was 85.1 percent, up 0.1 percentage point from the prior year cohort, and down 2.4 percentage points in comparison to the fall 2009 cohort. This new analysis reveals the disparities in student persistence across majors and program levels, regardless of the type of institution a student started. Measuring persistence through a winter term may offer a more complete picture for sub-baccalaureate programs. One-way ANOVA was used to analyse the annual citations and Altmetric scores of sub-datasets of cover and non-cover papers, and it was performed within a 95 % confidence interval of the average. All Rights Reserved. However, it is worth noting that China ranks fifteenth (15.99), the United States of America tenth (27.04), and Italy thirteenth (20.47) in terms of average citations per document. Citation rates were collected from PubMed for the first and corresponding author. It allows for contextual understanding as to the nature, purpose and motivation of the citingauthor/s and is a traditional tool for measuring impact using publication data. Refer to the last page of this report for additional definitions and notes on cohort selection. discover how a known idea or innovation has been confirmed, applied, improved, extended, or corrected.. The remaining 129 countries published less than ten articles on the aspect of traceability linked to food safety. Like all impact metrics, vulnerable to gamification (e.g.. Fall 2017 entering college students who were 21- to 24-years-old at college entry had a persistence rate of 57.6 percent. Journal rankings, after all the work developing them, were recently abandoned in Australia. Four-Year Public Institutions, Fall 2017 Entering Cohort by Race and Ethnicity, Figure 6. Among those who persisted in the second year, one in four students in Liberal Arts, Humanities, or General Studies continued enrollment in a different institution, a rate higher than in other majors shown in the figure. Fig. Some papers may receive only a few citations, while Over the years, the overall change in the Altmetric score shows an upward trend. The idea of comparing publications with other similar publications selected based on shared references (i.e., bibliographic coupling) is also discussed by Schubert and Braun (1993, 1996). A Field-Weighted Citation Impact of greater than 1.00 indicates that the publications have been cited more than would be expected based on the world average for similar publications, for example a score of 1.44 means that the outputs have been cited 44% more times than expected. Over the past nine years ending in 2017, an average of 13 percent or one in eight students who started college in any fall term transferred to a different institution by the following fall. Glnzel et al. 99th percentile is high, and indicates an article in the top 1% globally. An RCR of 1 is considered average, while an RCR greater than 1 is above average. WebThe theoretical model byOng et al. Black students had the lowest persistence rate (66.2 percent): just over half of black students returned to the starting institution (52.1 percent) and an additional 14.1 percent continued at a different institution. From the analysis, it can be concluded that the School of Food and Biological Engineering, Jiangsu University, Zhenjiang, China and China Agricultural University, Beijing, China, plays a significant role in the field of research. From 2000 to 2015, the top 1% extended its citation share from 14.7 to 19.6% in Ruiz-Castillo and Waltman (2015) also propose the use of an alternative classification system, but instead of using an existing classification system they algorithmically construct their own classification system based on a large-scale analysis of citation relations between publications (Waltman & Van Eck, 2012b). The 10-year averages are calculated from citations from articles published during the same 10-year period. First-Time StatusThis report uses historical Clearinghouse enrollment and degree data to confirm that students included in the study (1) showed no previous college enrollment and (2) had not previously completed a college degree or certificate. Field normalized citation metrics are used to attempt to contextualize the citation rate of an article to the expected citation rate of other articles of the same field, publication type, and publication year. Owing to the characteristics of high timeliness and low durability of the altmetrics indicators, the transmission speed and frequency of long-standing research papers in various media decreased. Other options include publication in a list of ranked journals, which can include rankings based on, Conclusion: Prometheus assessed and lessons for research assessment. This shows that economically developed nations have recognized the benefits of traceability solutions in food safety and are investigating their viability in order to ensure that the country's food is safe. Second, the average values of the Altmetric score and subdivision index data of cover papers were higher than those of non-cover papers, and the volatility over the years was higher than that of non-cover papers. We have noted that there is no simple relationship between citations and quality, but that citations do give some sort of evidence of notice, visibility or hierarchy in a discipline, and as such are a useful indicator in some disciplines at least. Source: National Research Council (2010a). The articles discussed in this section represent a new phase in the development of the literature on this topic. Among students who entered college at two-year public institutions in fall 2017, white students had a higher first-year persistence rate (67.1 percent) than Hispanic students (62.1 percent). Of all students who started college in this sector in fall 2017, 41.9 percent returned to the same institution in fall 2018.

For first-time students who started in associate degree-level programs in fall 2017, their overall persistence rates were lower compared to their peers in bachelors degree-level programs. As well as the overall rating, individual measures were developed for research activity, student support and outcomes, and student and faculty diversity.
