In science “there is no bad publicity”: Papers criticized in comments have high scientific impact

Comments are special types of publications whose aim is to correct or criticize previously published papers. For this reason, comments are believed to make commented papers less worthy or trusty to the eyes of the scientific community, and thus predestined to have low scientific impact. Here, we show that such belief is not supported by empirical evidence. We consider thirteen major publication outlets in science, and perform systematic comparisons between the citations accumulated by commented and non commented articles. We find that (i) commented papers are, on average, much more cited than non commented papers, and (ii) commented papers are more likely to be among the most cited papers of a journal. Since comments are published soon after criticized papers, comments should be viewed as early indicators of the future impact of criticized papers.

Review of somatic cell nuclear transfer in pig

It is now more than 8 years, since the first cloned pig from nuclear transfer was reported. Success of somatic cell nuclear transfer (SCNT) in pig is still low compared to that in bovine. Embryonic and neonatal abnormalities of cloned piglets are probably a result of incorrect or incomplete reprogramming of the transferred donor cell nuclei. Recently, technical refinements have resulted in a considerable increase of SCNT efficiency. The current level of efficiency is already sufficient for special purposes with high scientific and commercial impact including xenotransplantation, generation of human disease models and for biomedical studies. In this paper, we review current pig cloning methodologies for the technical and potential applications. Key words : Pig, somatic cell, nuclear transfer, oocyte and embryo.

Phenological models for the beginning of apple blossom in Germany

The classical paper of KOPPEN (1884a) on "The thermal zones of the Earth according to the duration of hot, moderate and cold periods and of the impact of heat on the organic world", published in the first volume of the Meteorologische Zeitschrift, is considered today as an early forerunner of the most widely used Koppen-Geiger climate classification. We depict the historical background of the evolution of Koppen's climate classification from the beginning in the early 19 th century until the present. An overview on 21 st century applications demonstrates the high scientific impact of Wladimir Koppen's historical work.

Catalysis by metal–organic frameworks: fundamentals and opportunities

Crystalline porous materials are extremely important for developing catalytic systems with high scientific and industrial impact. Metal-organic frameworks (MOFs) show unique potential that still has to be fully exploited. This perspective summarizes the properties of MOFs with the aim to understand what are possible approaches to catalysis with these materials. We categorize three classes of MOF catalysts: (1) those with active site on the framework, (2) those with encapsulated active species, and (3) those with active sites attached through post-synthetic modification. We identify the tunable porosity, the ability to fine tune the structure of the active site and its environment, the presence of multiple active sites, and the opportunity to synthesize structures in which key-lock bonding of substrates occurs as the characteristics that distinguish MOFs from other materials. We experience a unique opportunity to imagine and design heterogeneous catalysts, which might catalyze reactions previously thought impossible.

Fifteen common mistakes encountered in clinical research

The baseline standards for minimally acceptable science are improving as the understanding of the scientific method improves. Journals publishing research papers are becoming more and more rigorous. For example, in 2001 a group of authors evaluated the quality of clinical trials in anesthesia published over a 20 year period [Pua et al., Anesthesiology 2001;95:1068-73]. The authors divided the time into 3 subgroups and analyzed and compared the quality assessment score from research papers in each group. The authors reported that the scientific quality scores increased significantly in this time, showing more randomization, sample size calculation and blinding of studies. Because every journal strives to have a high scientific impact factor, research quality is critical to this goal. This means novice researchers must study, understand and rigorously avoid the common mistakes described in this review. Failure to do so means the hundreds and hundreds of hours of effort it takes to conduct and write up a clinical trial will be for naught, in that the manuscript with be rejected or worse yet, ignored. All scientists have a responsibility to understand research methods, conduct the best research they can and publish the honest and unbiased results.

Scientific Impact: Opportunity and Necessity

Recent National Institutes of Health changes have focused attention on the potential scientific impact of research projects. Research with the excellent potential to change subsequent science or health care practice may have high scientific impact. Only rigorous studies that address highly significant problems can generate change. Studies with high impact may stimulate new research approaches by changing understanding of a phenomenon, informing theory development, or creating new research methods that allow a field of science to move forward. Research with high impact can transition health care to more effective and efficient approaches. Studies with high impact may propel new policy developments. Research with high scientific impact typically has both immediate and sustained influence on the field of study. The article includes ideas to articulate potential scientific impact in grant applications as well as possible dissemination strategies to enlarge the impact of completed projects.

Scoliosis: density-equalizing mapping and scientometric analysis

BackgroundPublications related to scoliosis have increased enormously. A differentiation between publications of major and minor importance has become difficult even for experts. Scientometric data on developments and tendencies in scoliosis research has not been available to date. The aim of the current study was to evaluate the scientific efforts of scoliosis research both quantitatively and qualitatively.MethodsLarge-scale data analysis, density-equalizing algorithms and scientometric methods were used to evaluate both the quantity and quality of research achievements of scientists studying scoliosis. Density-equalizing algorithms were applied to data retrieved from ISI-Web.ResultsFrom 1904 to 2007, 8,186 items pertaining to scoliosis were published and included in the database. The studies were published in 76 countries: the USA, the U.K. and Canada being the most productive centers. The Washington University (St. Louis, Missouri) was identified as the most prolific institution during that period, and orthopedics represented by far the most productive medical discipline. "BRADFORD, DS" is the most productive author (146 items), and "DANSEREAU, J" is the author with the highest scientific impact (h-index of 27).ConclusionOur results suggest that currently established measures of research output (i.e. impact factor, h-index) should be evaluated critically because phenomena, such as self-citation and co-authorship, distort the results and limit the value of the conclusions that may be drawn from these measures. Qualitative statements are just tractable by the comparison of the parameters with respect to multiple linkages. In order to obtain more objective evaluation tools, new measurements need to be developed.

거대 마젤란 망원경의 논문 생산성 예측

Productivity of the Giant Magellan Telescope is estimated based on the annual number of papers produced by the currently operating large telescopes such as the telescope at the ESO La Silla observatory, CFHT, AAT, the Magellan telescopes, ESO VLT, Japanese Subaru, the Gemini telescopes, and the Keck telescopes. We find that the amount of papers produced by a large telescope is roughly proportional to the diameter of its primary mirror. With this fact, we estimate the SCI-paper productivity of the Giant Magellan Telescope by extrapolating the productivity of the above-mentioned large telescopes. Moreover, according to the paper written in 2001 by Benn and Sanchez, the amount of highly-cited papers produced by a large telescope is roughly proportional to the light-gathering power of the telescope or the square of the diameter. Hence, we survey the productivity of Nature-class papers of the large telescopes and extrapolate the relationship to estimate the productivity of the Nature-class papers by using the Giant Magellan telescope of a filled aperture 21.4 meters in diameter. We expect that Korean astronomers will be able to produce annually 60 SCI-class papers and 20 Nature-class papers with high scientific impact by using the telescope-time corresponding to the 10% share of the Giant Magellan Telescope.

Los estudios sobre el riñón y la circulación renal de Josep Trueta i Raspall (1897-1977)

IntroductionJosep Trueta i Raspall, born in Barcelona in 1897, was one of the most outstanding european surgeons of his time. In 1936, after the military coup and during the subsequent Spanish civil war, he was in charge of the Surgery Service at the Hospital de la Santa Creu y Sant Pau and begins to performe a closed method to treat open fractures of the limbs, dramatically lowering the number of gangrenes and amputations between troops and civilians. At the end of the war came the exile, and he was invited by the british Health Service, he teach in Oxford and applies his knowledge on war surgery, was named PhD (Hon) and professor of ortopedics, and creates an school of clinical investigation that generates important findings in bone growing and pathology and, amont other areas, in the knowledge of renal function and kidney injuries induced by shock and blood hypertension. One of the most outstanding fruits of this investigation is the book “Studies on renal circulation”, first published in English in 1947 (Oxford), then in Spanish in 1949 (Barcelona). Material and methodsStudy of Josep Trueta’s biography and works on kidney function, especially the book “Studies on the renal circulation”,relating them to the state-of- the- art of nephrologic studies of his time. ResultsTrueta and his group were pioneers in the study of the causes of postraumatic oliguria in war wounds. On the basis of the first studies on crush syndrome, published in 1941, were the kidney failure that followed the extended injuries of the limbs was pointed out, they could demonstrated the changes in renal circulation that followed different injuries to the limbs, such as ischemia, haemorrhage and infections. “Studies on the renal circulation” and other papers published in journals of high scientific impact, shown the renal cortical ischemia with preservation or increase of the medullar and yuxtamedullar circulation that takes place in those pathological situations (Trueta shunt). Although their contributions and hypothesis were not definitives, they served as the basis to studies performed later on, on acute kidney failure secondary to shock, glomerulonephritis, transplant rejection and blood hypertension. CommentTrueta’s works are unusual examples of investigations directed to answer clinical questions. What may calls one’s attention is the wide field of investigation he moves on, that today would involved several medical specialities, different to his task as orthopedic surgeon. On the other hand, his love by Catalonia, his country, moves him to write “The spirit of Catalonia” (1946), a short text for English-speaking people, on the political and scientific history of Catalonia. Trueta was in the end, an humanistic intellectual with broad interests, reflected on his books on travels or on the life of classic sages such as Luis Vives, Miguel Servet or Cajal. He returned back to Catalonia in 1966 and died in 1977. His book “Studies on the renal circulation”, exquisitely illustrated and edited deserves a distinguished place in the European medical and urological historiography.

A new year for Cytometry part A

will be the first year that Cytometry Part A appears com-pletely with the new look and the new article categories. Sincelast year Cytometry Part A underwent a number of changes andimprovements. We not only changed and refreshed the lay-outof the journal and the manuscripts but also added several newfeatures such as the Journal Roundup and In This Issue and newor modified article categories (1). Most important of all, thequality and the number of manuscripts is increasing and wehave, with the excellent support of the editorial office, success-fully improved manuscript processing.I am happy to announce that we have achieved a clearreduction in the turn-around time for manuscripts. In themean it takes now less than 30 days from submission of a newmanuscript until the final decision is made. This goal couldonly be achieved by the tremendously high quality work ofour new Associate Editors, Editorial Board Members andreviewers. I wish to express my gratitude to them. They areperforming excellent work by selecting the best from all sub-mitted manuscripts and helping the authors to improve theirscientific publications.Most of all I wish to acknowledge our authors: yourexciting work helps to bring our Journal forward. Since ourJournal has improved its Impact Factor in the last year wealso encountered a clear increase in the number of manu-script submissions. This enables us to select the best of theavailable material. As a consequence our rejection rateincreased to over 30%.

Uniform Resource Locator Decay in Dermatology Journals

To describe dermatology journal uniform resource locator (URL) use and persistence and to better understand the level of control and awareness of authors regarding the availability of the URLs they cite. Software was written to automatically access URLs in articles published between January 1, 1999, and September 30, 2004, in the 3 dermatology journals with the highest scientific impact. Authors of publications with unavailable URLs were surveyed regarding URL content, availability, and preservation. Uniform resource locator use and persistence and author opinions and practices. The percentage of articles containing at least 1 URL increased from 2.3% in 1999 to 13.5% in 2004. Of the 1113 URLs, 81.7% were available (decreasing with time since publication from 89.1% of 2004 URLs to 65.4% of 1999 URLs) (P<.001). Uniform resource locator unavailability was highest in The Journal of Investigative Dermatology (22.1%) and lowest in the Archives of Dermatology (14.8%) (P=.03). Some content was partially recoverable via the Internet Archive for 120 of the 204 unavailable URLs. Most authors (55.2%) agreed that the unavailable URL content was important to the publication, but few controlled URL availability personally (5%) or with the help of others (employees, colleagues, and friends) (6.7%). Uniform resource locators are increasingly used and lost in dermatology journals. Loss will continue until better preservation policies are adopted.

Microgravity and Macromolecular Crystallography

Macromolecular crystal growth is seen as an ideal experiment to make use of the reduced acceleration environment provided by an orbiting spacecraft. The experiments are small, are simply operated, and have a high potential scientific and economic impact. In this review we examine the theoretical reasons why microgravity is a beneficial environment for crystal growth and survey the history of experiments on the Space Shuttle Orbiter, on unmanned spacecraft, and on the Mir space station. The results of microgravity crystal growth are considerable when one realizes that the comparisons are always between few microgravity-based experiments and a large number of earth-based experiments. Finally, we outline the direction for optimizing the future use of orbiting platforms.

Intermediate outcomes: Diagnostic and therapeutic impact

The conceptual basis for intermediate outcomes has been established, and scientifically sound methods are available for assessment of these short-term outcomes. While modest intermediate outcomes research experience assessing imaging technology has accumulated in the literature, much more remains to be done, for the benefit of both patients and physicians. I would recommend that intermediate outcomes research become more focused on assessment earlier in the diffusion phase of imaging technology development. These studies should be based on traditional diagnostic accuracy studies, but these should be extended to include well-designed, high scientific quality treatment impact studies. Furthermore, such studies need to be multidisciplinary and multiinstitutional/multisite and include patient utility assessment components.

Harvard Tops in Scientific Impact
