Impact of data sources on citation counts and rankings of LIS faculty: Web of science versus scopus and google scholar
Authors: Meho Lokman I. , Yang Kiduk
Published: August 2007

The Institute for Scientific Information's (ISI, now Thomson Scientific, Philadelphia, PA) citation databases have been used for decades as a starting point and often as the only tools for locating citations and/or conducting citation analyses. The ISI databases (or Web of Science [WoS]), however, may no longer be sufficient because new databases and tools that allow citation searching are now available. Using citations to the work of 25 library and information science (LIS) faculty members as a case study, the authors examine the effects of using Scopus and Google Scholar (GS) on the citation counts and rankings of scholars as measured by WoS. Overall, more than 10,000 citing and purportedly citing documents were examined. Results show that Scopus significantly alters the relative ranking of those scholars that appear in the middle of the rankings and that GS stands out in its coverage of conference proceedings as well as international, non‐English language journals. The use of Scopus and GS, in addition to WoS, helps reveal a more accurate and comprehensive picture of the scholarly impact of authors. The WoS data took about 100 hours of collecting and processing time, Scopus consumed 200 hours, and GS a grueling 3,000 hours.
Does domain knowledge matter: Mapping users' expertise to their information interactions
Authors: Ju Boryung
Published: August 2007

The purpose of this study is to investigate the role that domain knowledge plays in users' interactions with information systems. Two groups of users with two different areas of expertise were recruited for 34 experimental sessions to answer two research questions: (a) Does one group's domain knowledge (Geography majors) affect their performance on an information system more than another group's domain knowledge (Computer Science majors)? (b) Are there any differences and/or similarities in the performance of the two groups in terms of the information problem‐solving processes? Task completion time, task completeness, and mouse movements were collected while users performed six tasks during the experimental sessions. Data were analyzed through repeated measures. An ANOVA was used for task completion time and task completeness. GOMS (Goals, Operators, Methods, and Selection rules) was also used for mouse movements to identify some of the similarities and differences between the two groups' information problem‐solving processes. The GOMS analysis found the two groups' processing activities to be remarkably similar. The ANOVA results indicate that expertise type was not a major factor influencing user performance, but task and task combined with the type of expertise played a significant role in the users' interactions with the interface. External operators, goal decompositions, and methods related to the problem solving process through GOMS are also presented.
Comparison of full‐text searching to metadata searching for genes in two biomedical literature cohorts
Authors: Hemminger Bradley M. , Saelim Billy , Sullivan Patrick F. , Vision Todd J.
Published: August 2007

Researchers have traditionally used bibliographic databases to search out information. Today, the full‐text of resources is increasingly available for searching, and more researchers are performing full‐text searches. This study compares differences in the number of articles discovered between metadata and full‐text searches of the same literature cohort when searching for gene names in two biomedical literature domains. Three reviewers additionally ranked 100 articles in each domain. Significantly more articles were discovered via full‐text searching; however, the precision of full‐text searching also is significantly lower than that of metadata searching. Certain features of articles correlated with higher relevance ratings. A significant feature measured was the number of matches of the search term in the full‐text of the article, with a larger number of matches having a statistically significant higher usefulness (i.e., relevance) rating. By using the number of hits of the search term in the full‐text to rank the importance of the article, performance of full‐text searching was improved so that both recall and precision were as good as or better than that for metadata searching. This suggests that full‐text searching alone may be sufficient, and that metadata searching as a surrogate is not necessary.
Estimation and Confidence Regions for Multi‐Dimensional Effective Dose
Authors: Li Jialiang , Nordheim Erik V. , Zhang Chunming , Lehner Charles E.
Published: August 2007

The problem of finding confidence regions for multiple predictor variables corresponding to given expected values of a response variable has not been adequately resolved. Motivated by an example from a study on hyperbaric exposure using a logistic regression model, we develop a conceptual framework for the estimation of the multi‐dimensional effective dose for binary outcomes. Thek‐dimensional effective dose can be determined by conditioning onk– 1 components and solving for the last component as a conditional univariate effective dose. We consider various approaches for calculating confidence regions for the multi‐dimensional effective dose and compare them via a simulation study for a range of possible designs. We analyze data related to decompression sickness to illustrate our procedure. Our results provide a practical approach to finding confidence regions for predictor variables for a given response value. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Molecular characterization of reconstructed skin model by Raman microspectroscopy: Comparison with excised human skin
Authors: Tfayli Ali , Piot Olivier , Draux Florence , Pitre Franck , Manfait Michel
Published: August 2007

Human skin is directly exposed to different exogenous agents. Many research works have studied the diffusion, interactions, absorption mechanisms, and/or toxicity of these agents toward different cutaneous structures. With the use of living animals for such tests being more and more rejected; and the number of human volunteers being limited; different types of skin models are used. In the last few years, reconstructed epidermis from cell cultures has been frequently employed, and recent changes in the European chemical policy have approved and encouraged the use of these reconstructed models for skin‐related research works and assessments. Among the techniques used actually to study the skin, Raman microspectroscopy is a rising and powerful nondestructive technique that detects characteristic molecular vibrations. In this study, we created a spectral database to index the vibration peaks and bands of a well‐known reconstructed epidermis model, the Episkin®. The comparison with a native epidermis signal enabled us to put in evidence several spectral differences associated with molecular and structural differences between the skin and the reconstructed model, both maintained in living conditions. In addition to that, we have showed the feasibility of tracking the penetration of a pharmaceutical molecule through the Episkin model. © 2007 Wiley Periodicals, Inc. Biopolymers 87: 261–274, 2007.

Elucidation of the ribonuclease a aggregation process mediated by 3D domain swapping: A computational approach reveals possible new multimeric structures
Authors: Cozza Giorgio , Moro Stefano , Gotte Giovanni
Published: August 2007

By lyophilization from 40% acetic acid solutions, bovine pancreatic ribonuclease A forms several three‐dimensional (3D) domain‐swapped oligomers: dimers, trimers, tetramers, pentamers, hexamers, and traces of high‐order oligomers, purifiable by cation‐exchange chromatography. Each oligomeric species consists of at least two conformers displaying different basicity density, and/or exposure of positive charges. The structures of the two dimers and one trimer have been solved. Plausible models have been proposed for a second RNase A trimer and four tetramers, but not all the models are certainly assignable to the tetramers purified. Further studies have also been made on the pentameric and hexameric species, again without reaching structurally clear‐cut results. This work is focused on the detailed modeling of the tetrameric RNase A species, using four different approaches to possibly clarify unknown structural aspects. The results obtained do not confirm the validity of one tetrameric model previously proposed, but allow the proposal of a novel tetrameric structure displaying new interfaces that are absent in the other known conformers. New details concerning other tetrameric structures are also described. RNase A multimers larger than tetramers, i.e., pentamers, hexamers, octamers, nonamers, up to dodecamers, are also modeled, with the proposal of novel domain‐swapped structures, and the confirmation of what had previously been inferred. Finally, the propensity of RNase A to possibly form high‐order supramolecular multimers is analyzed starting from the large number of domain‐swapped RNase A conformers modeled. © 2007 Wiley Periodicals, Inc.

Meta-analysis of holmium laser enucleation versus transurethral resection of the prostate for symptomatic prostatic obstruction
Authors: Tan A , Liao C , Mo Z , Cao Y
Published: August 2007

Background

Holmium laser enucleation (HoLEP) is an alternative to transurethral resection (TURP) of the prostate for symptomatic prostatic obstruction.

Methods

Randomized controlled trials comparing HoLEP and TURP were identified systematically using Medline, Embase and The Cochrane Library. Primary outcomes were peak urinary flow rate (Qmax), postvoid residual volume, symptom score and quality of life. Secondary outcomes were duration of operation, hospital stay, blood loss, catheterization time and adverse events.

Results

There was no statistically significant difference between HoLEP and TURP in terms of Qmax at 6 and 12 months' follow-up. HoLEP was associated with significantly less blood loss, a shorter catheterization time and a shorter hospital stay. TURP was associated with reduced operating time. The techniques were similar in terms of urethral stricture, stress incontinence, transfusion requirement and rate of reintervention.

Conclusion

HoLEP and TURP provide a similar improvement in Qmax. HoLEP, however, has several advantages over TURP, despite requiring more operating time. It is at least as safe as TURP in terms of adverse events.
Innovation and competitive advantages from the integration of strategic aspects with social and environmental management in European firms
Authors: Wagner Marcus
Published: August 2007

This paper analyses the nature and details of the association that the integration of social and environmental considerations with corporate strategy has for different competitive advantages and innovation activities at the firm level. Its objective is to answer the question as to whether a positive link exists between integration and the effects of environmental and social performance on these different dimensions of economic performance. The question of the specific form of this relationship is also raised. These questions are analysed using cluster analysis and regression models. Results are presented for four different dimensions of competitive advantage, and for two types of innovation activity. These raise the possibility that the process of integration is more important for bringing about a positive link than a resulting integration type.

Comparing the anatomical consistency of the posterior superior iliac spine to the iliac crest as reference landmarks for the lumbopelvic spine: A retrospective radiological study
Authors: McGaugh J.M. , Brismée J.M. , Dedrick G.S. , Jones E.A. , Sizer P.S.
Published: August 2007

A palpation reference line coursing between the superior‐most aspect of the iliac crests has been reported to cross the L4 spinous process or L4/L5 intervertebral space in ∼80% of the population. Comparable data have not been defined for the line coursing between the posterior superior iliac spines (PSIS). The purpose of this study was to compare the anatomical consistency of the PSIS to the iliac crest as landmarks used for spinal palpation. One hundred computerized tomographic images were reviewed in a three‐dimensional setting. Two horizontal lines were constructed on each image: Line 1 representing the superior‐most aspect of the iliac crest and Line 2 representing the inferior margin of the PSIS. The vertical distance between each horizontal line and the inferior edge of its respective spinous process were measured. The PSIS corresponded to the S2 spinous process in 81% of subjects and the iliac crest to the L4 spinous process in 59% of subjects. Distance measures suggest that the PSIS was closer to S2 versus the iliac crest to L4 (t = 6.998; P < 0.01). The PSIS crossed S2 more frequently than the iliac crest crossed L4 (χ2 = 12.719, P ≤ 0.01). The study findings support the relationship between the PSIS, and the spinous process of S2 is more consistent when compared to the iliac crest and the spinous process of L4. The PSIS reference line may be used to find S2 as a reference standard in validity and reliability palpation studies in the lower lumbar spine. Clin. Anat. 20:819–825, 2007. © 2007 Wiley‐Liss, Inc.
Vertebral body shape variation in the thoracic and lumbar spine: Characterization of its asymmetry and wedging
Authors: Masharawi Youssef , Salame Khalil , Mirovsky Yigal , Peleg Smadar , Dar Gali , Steinberg Nili , Hershkovitz Israel
Published: August 2007

This study was designed to characterize the vertebral body (VB) shape, focusing on vertebral wedging, along the thoracic and lumbar spine, and to look for shape variations with relation to gender, age, and ethnicity. All thoracic and lumbar (T1–L5) dissected vertebrae of 240 individuals were measured and analyzed by age, gender, and ethnicity. A 3D digitizer was used to measure all VB lengths, heights, and widths, and their ratios were calculated. This study showed that the VB size was independent of age or ethnicity. VB left lateral wedging was found in most vertebrae of most individuals, yet systematically was absent in six vertebrae (T4, T8–T9, T11, L3–L4) with a greater tendency in females than males (∼92% vs. 86%). The VB was anteriorly wedged from T1 through L2 (peak at T7), nonwedged at L3, and posteriorly wedged at L4–L5 (peak at L5). VB width decreased from T1 to T4 and then increased toward L4–L5, so that the spinal configuration in the coronal plane resembled two pyramids of opposite directions, sharing an apex at T4. The inferior VB width was significantly greater than the superior width of both the same vertebra and the adjacent lower vertebra, indicating a trapezoidal shape of the VB and an inverted trapezoidal shape of the intervertebral space. In conclusion, these findings indicate that the human vertebra, in its normal condition, maintains its external dimensions with age, independent of gender or ethnic origin. Clinical and surgical implications of the unique thoracolumbar architecture are discussed. Clin. Anat. 21:46–54, 2008. © 2007 Wiley‐Liss, Inc.
Geographical classification of olive oils by the application of CART and SVM to their FT‐IR
Authors: Caetano Sónia , Üstün Bülent , Hennessy Siobhán , Smeyers‐Verbeke Johanna , Melssen Willem , Downey Gérard , Buydens Lutgarde , Heyden Yvan Vander
Published: August 2007

This paper reports the application of Fourier‐transform infrared (FT‐IR) spectroscopy to the geographical classification of extra virgin olive oils. Two chemometrical techniques, classification and regression trees (CART) and support vector machines (SVM) based on the Gaussian kernel and the recently introduced Euclidean distance‐based Pearson VII Universal Kernel (PUK), were applied to discriminate between Italian and non‐Italian and between Ligurian and non‐Ligurian olive oils. The PUK is applied in literature with success on regression problems. In this paper the mapping power of this universal kernel for classification was investigated. In this study it was observed that SVM performed better than CART. SVM based on the PUK provide models with a high selectivity and sensitivity (thus a better accuracy) as compared to those obtained using the Gaussian kernel. The wave numbers selected in the classification trees were interpreted demonstrating that the trees were chemically justified. This study also shows that FT‐IR spectroscopy associated with SVM and CART can be used to correctly discriminate between various origins of olive oils, demonstrating that the combination of techniques might be a powerful tool for supporting the claimed origin of olive oils.
