Reprint of “Citation analysis as a measure of article quality,journal influence and individual researcher performance” 总被引:1,自引:0,他引:1
The research-related performance of universities, as well as that of individual researchers, is increasingly evaluated through the use of objective measures, or metrics, which seek to support or in some cases even replace more traditional methods of peer review. In particular there is a growing awareness in research communities, government organisations and funding bodies around the concept of using evaluation metrics to analyse research citations. The tools available for ‘citation analysis’ are many and varied, enabling a quantification of scientific quality, academic impact and prestige. However there is increasing concern regarding the potential misuse of such tools, which have limitations in certain research disciplines.This article uses ‘real world’ examples from radiography research and scholarship to illustrate the range of currently available citation analysis tools. It explores the academic debate surrounding their strengths and limitations, and identifies the potential impact of citation analysis on the radiography research community.The article concludes that citation analysis is a valuable tool for researchers to use for personal reflection and research planning, yet there are inherent dangers if it is used inappropriately. Whilst citation analysis can give objective information regarding an individual, research group, journal or higher education institution, it should not be used as a total substitute for traditional qualitative review and peer assessment. 相似文献

Artificial antigen-presenting constructs efficiently stimulate minor histocompatibility antigen-specific cytotoxic T lymphocytes 总被引:5,自引:0,他引:5 下载免费PDF全文

Cytotoxic T lymphocytes (CTLs) specific for hematopoietic-restricted minor histocompatibility antigens (mHags) are important reagents for adoptive immunotherapy of relapsed leukemia after allogeneic stem cell transplantation. However, expansion of these CTLs to therapeutic numbers is often hampered by the limited supply of antigen-presenting cells (APCs). Therefore, we evaluated whether cell-sized latex beads coated with HLA/mHag complexes HLA-A2/HA-1 or HLA-A2/HA-2 and recombinant CD80 and CD54 molecules can replace professional APCs. The artificial antigen-presenting constructs (aAPCs) effectively stimulated HA-1 and HA-2specific CTL clones as shown by ligand-specific expansion, cytokine production, and maintenance of cytotoxic activity, without alteration of CTL phenotype. Furthermore, HA-1specific polyclonal CTL lines were enriched as efficiently by aAPCs as by autologous HA-1 peptide-pulsed dendritic cells. Thus, aAPCs coated with HLA/mHag complexes, CD80, and CD54 may serve as tools for in vitro enrichment of immunotherapeutic mHag-specific CTL lines. 相似文献

High-dose immunosuppressive therapy and autologous peripheral blood stem cell transplantation for severe multiple sclerosis 总被引:10,自引:1,他引:10
Nash RA Bowen JD McSweeney PA Pavletic SZ Maravilla KR Park MS Storek J Sullivan KM Al-Omaishi J Corboy JR DiPersio J Georges GE Gooley TA Holmberg LA LeMaistre CF Ryan K Openshaw H Sunderhaus J Storb R Zunt J Kraft GH 《Blood》2003,102(7):2364-2372
There were 26 patients enrolled in a pilot study of high-dose immunosuppressive therapy (HDIT) for severe multiple sclerosis (MS). Median baseline expanded disability status scale (EDSS) was 7.0 (range, 5.0-8.0). HDIT consisted of total body irradiation, cyclophosphamide, and antithymocyte globulin (ATG) and was followed by transplantation of autologous, granulocyte colony-stimulating factor (G-CSF)-mobilized CD34-selected stem cells. Regimen-related toxicities were mild. Because of bladder dysfunction, there were 8 infectious events of the lower urinary tract. One patient died from Epstein-Barr virus (EBV)-related posttransplantation lymphoproliferative disorder (PTLD) associated with a change from horse-derived to rabbit-derived ATG in the HDIT regimen. An engraftment syndrome characterized by noninfectious fever with or without rash developed in 13 of the first 18 patients and was associated in some cases with transient worsening of neurologic symptoms. There were 2 significant adverse neurologic events that occurred, including a flare of MS during mobilization and an episode of irreversible neurologic deterioration after HDIT associated with fever. With a median follow-up of 24 (range, 3-36) months, the Kaplan-Meier estimate of progression (>/= 1.0 point EDSS) at 3 years was 27%. Of 12 patients who had oligoclonal bands in the cerebrospinal fluid at baseline, 9 had persistence after HDIT. After HDIT, 4 patients developed new enhancing lesions on magnetic resonance imaging of the brain. The estimate of survival at 3 years was 91%. Important clinical issues in the use of HDIT and stem cell transplantation for MS were identified; however, modifications of the initial approaches appear to reduce treatment risks. This was a heterogeneous high-risk group, and a phase 3 study is planned to fully assess efficacy. 相似文献

Background To compare RCB (Residual Cancer Burden) and Neo-Bioscore in terms of prognostic performance and see if adding pathological variables improve these scores.Methods We analysed 750 female patients with invasive breast cancer (BC) treated with neoadjuvant chemotherapy (NAC) at Institut Curie between 2002 and 2012. Scores were compared in global population and by BC subtype using Akaike information criterion (AIC), C-Index (concordance index), calibration curves and after adding lymphovascular invasion (LVI) and pre-/post-NAC TILs levels.Results RCB and Neo-Bioscore were significantly associated to disease-free and overall survival in global population and for triple-negative BC. RCB had the lowest AICs in every BC subtype, corresponding to a better prognostic performance. In global population, C-Index values were poor for RCB (0.66; CI [0.61–0.71]) and fair for Neo-Bioscore (0.70; CI [0.65–0.75]). Scores were well calibrated in global population, but RCB yielded better prognostic performances in each BC subtype. Concordance between the two scores was poor. Adding LVI and TILs improved the performance of both scores.Conclusions Although RCB and Neo-Bioscore had similar prognostic performances, RCB showed better performance in BC subtypes, especially in luminal and TNBC. By generating fewer prognostic categories, RCB enables an easier use in everyday clinical practice.Subject terms: Breast cancer, Breast cancer, Chemotherapy 相似文献

Problematic substance use is a challenge worldwide among adolescents. The recovery process requires holistic support addressing multiple and intersecting substance use risk factors; yet, there remains a lack of evidence on how to best understand and support adolescents in recovery. Recovery capital (RC) is a model that can be used to identify areas of assets that could be enhanced and barriers to address in one’s recovery process; however, this construct was generated through a study of adults who achieved natural recovery and it has since been used to frame adult recovery-related literature across the world. The primary aim of this article is to outline the rationale for and present a Recovery Capital for Adolescents Model (RCAM). The article will discuss the original recovery capital model, describe adolescent development, substance use, and recovery, and detail proposed developmental adaptations. Future qualitative and quantitative research should explore the RCAM to assess whether the proposed dimensions are complete as well as to assess its utility in clinical settings for identifying strengths and barriers for adolescents in or seeking recovery. 相似文献
