AIMS: The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. PATIENTS AND METHODS: A survey was developed to assess service functionality and quality from the users' viewpoint. During a 6-month period, a questionnaire was mailed to 194 patients and relatives who previously used the CIP-LP; 113 (58%) were returned and processed. RESULTS: Of the respondents, 91% were pleased with the CIP-LP and 95% would recommend the service to other people. The information obtained contributed to a clearer understanding of the illness and treatment (45% as first answer) and a better control of the situation (33%). Fifty-one per cent evaluated the information received as 'good', 42%'excellent' and 4%'of sufficient quality'. CONCLUSION: This survey shows the appreciation and usefulness in the users' perception of a specific hospital library for cancer patients and their relatives, providing an information service supplementary to doctor-patient communication.  相似文献   

The white colour in Etruscan polychromes on terracotta: Spectroscopic identification of kaolin     

Francesca Bordignon  Paolo Postorino  Alessandro Nucara  Paolo Dore  Giorgio Trojsi  Vincenzo Bellelli 《Journal of Cultural Heritage》2008,9(1):23

The present work reports on a spectroscopic study of white colour samples collected from Etruscan polychromes on terracotta from the Cerveteri area. In particular, both white-on-red potsherds of the Orientalising period and high-value polychromes of the Archaic period were considered. The white pigment, a fundamental element in this class of artworks, was not clearly identified in previous archaeological and analytical studies, although the use of kaolin was tentatively proposed. Therefore, samples from the Monte Sughereto kaolin quarry in the Cerveteri area were also studied. The results of detailed analyses carried out using micro-Raman spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy first show that the quarry material is a high-purity kaolin containing quartz. Raman results strongly suggest that the same kind of kaolin was employed in the polychromes of the Archaic period. As to white-on red potsherds, infrared results have a key role in showing that the white pigment is a kaolin closely corresponding to the quarry material since a particular kaolin polytype (dickite) is dominant in both cases. The present work thus provides the first definitive identification of the white pigment used in Etruscan polychromes on terracotta from the Cerveteri area, and suggests that the source of kaolin might be the Monte Sughereto quarry.  相似文献

Query reformulation mining: models,patterns, and applications   总被引：1，自引：0，他引：1  

Paolo Boldi  Francesco Bonchi  Carlos Castillo  Sebastiano Vigna 《Information Retrieval》2011,14(3):257-289

Understanding query reformulation patterns is a key task towards next generation web search engines. If we can do that, then we can build systems able to understand and possibly predict user intent, providing the needed assistance at the right time, and thus helping users locate information more effectively and improving their web-search experience. As a step in this direction, we build a very accurate model for classifying user query reformulations into broad classes (generalization, specialization, error correction or parallel move), achieving 92% accuracy. We then apply the model to automatically label two very large query logs sampled from different geographic areas, and containing a total of approximately 17 million query reformulations. We study the resulting reformulation patterns, matching some results from previous studies performed on smaller manually annotated datasets, and discovering new interesting reformulation patterns, including connections between reformulation types and topical categories. We annotate two large query-flow graphs with reformulation type information, and run several graph-characterization experiments on these graphs, extracting new insights about the relationships between the different query reformulation types. Finally we study query recommendations based on short random walks on the query-flow graphs. Our experiments show that these methods can match in precision, and often improve, recommendations based on query-click graphs, without the need of users’ clicks. Our experiments also show that it is important to consider transition-type labels on edges for having recommendations of good quality.  相似文献   

Effectiveness of bibliographic searches performed by paediatric residents and interns assisted by librarians. A randomised controlled trial     

Gardois P  Calabrese R  Colombi N  Deplano A  Lingua C  Longo F  Villanacci MC  Miniero R  Piga A 《Health information and libraries journal》2011,28(4):273-284

Background: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. Objectives: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real‐life clinical scenarios. Methods: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non‐assisted (control) group. Each participant searched Pub Med and other online sources, performing pre‐determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. Results: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8–33.2), in favour of the assisted group (P‐value, Mann–Whitney U test: 0.013). Conclusions: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.  相似文献

Science or graduates: How do firms benefit from the proximity of universities?     

Bart Leten  Paolo Landoni  Bart Van Looy 《Research Policy》2014

This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies.  相似文献   

Evaluating the Power of Latent Growth Curve Models to Detect Individual Differences in Change     

Christopher Hertzog  Timo von Oertzen  Paolo Ghisletta  Ulman Lindenberger 《Structural equation modeling》2013,20(4):541-563

We evaluated the statistical power of single-indicator latent growth curve models to detect individual differences in change (variances of latent slopes) as a function of sample size, number of longitudinal measurement occasions, and growth curve reliability. We recommend the 2 degree-of-freedom generalized test assessing loss of fit when both slope-related random effects, the slope variance and intercept-slope covariance, are fixed to 0. Statistical power to detect individual differences in change is low to moderate unless the residual error variance is low, sample size is large, and there are more than four measurement occasions. The generalized test has greater power than a specific test isolating the hypothesis of zero slope variance, except when the true slope variance is close to 0, and has uniformly superior power to a Wald test based on the estimated slope variance.  相似文献

Ginzburg in Harlem: History,Structure and the Politics of Primitivism     

Paolo Palladino 《Culture, Theory & Critique》2013,54(2):203-217

Abstract

The historian Carlo Ginzburg is renowned for his critique of modern, scientific reason and his articulation of an alternative form of knowledge which he labels ‘conjectural’. This form of knowledge, supposedly more attuned to the historian’s interest in the singular and specific fragment, as opposed to the abstract and universal concept, is so rooted in the practices of the prehistoric hunter that Ginzburg sometimes describes it as a ‘venatic’ form of deduction, binding ‘the human animal closely to other animal species’. In this essay, I explore the ramifications of this alternative form of knowledge, attending especially to its relationship to the modernist theme of ‘primitivism’. I do so by juxtaposing Ginzburg’s critical appraisal of Arthur Conan Doyle’s most famous literary invention, Sherlock Holmes, and Rudolph Fisher’s own literary invention, John Archer, the physician who sometimes aids criminal investigations in African American Harlem. I argue that the differences between Archer and Holmes draw attention to some troubling implications of Ginzburg’s historiographical argument. Folding this analysis on itself, however, I also suggest that what might be at stake, when Ginzburg insists so troublingly on the importance of the singular, venatic trace, is the evocation of Walter Benjamin’s understanding of the historical ‘event’.  相似文献
