FIRST ASSESSMENTS ON HERITAGE SCIENCE ORIENTED IMAGE-BASED MODELING USING LOW-COST MODIFIED AND MOBILE CAMERAS
Full text linkThree-dimensional modeling of cultural heritage, especially concerning large scale studies, as for example, archaeometry, diagnostics and conservation intervention applications, which usually require high-resolution and multi-spectral analyses, necessitates the use of complicate and often expensive equipment. Recent developments regarding low-cost commercially available spectrally modified digital reflex cameras, smartphones with good quality image sensors, mobile thermal cameras in combination with automated or semi-automated photogrammetric software implementing Structure from Motion (SfM) and Multiview Stereo (MVS) algorithms constitute some cheaper and simpler alternatives. Although, the results of the integration of these types of sensors and techniques are often not evaluated as metric products. The presented research combines the above-mentioned instrumentation and software to implement and evaluate low-cost 3D modeling solutions on heritage science-oriented case studies, but also to perform some first assessments on the resulting models' metric properties, quality of texture and usefulness for further scientific investigations
Personality matters: relationship between personality characteristics, spirituality, demoralization, and perceived quality of life in a sample of end-of-life cancer patients
Full text linkPurpose: Personality could be an interesting dimension to explore in end-of-life cancer patients, in order to investigate how personality affects quality of life. Thus, this study aimed to investigate the relationship among personality through the Big Five Inventory (BFI), spirituality, and demoralization and to explore their impact on their quality of life. Methods: A sample of 210 end-of-life Italian cancer patients were assessed with the BFI, the Demoralization Scale (DS), the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-SP-12), the Functional Assessment of Cancer Therapy Scale–General Measure (FACT-G), and the Karnofsky performance status. Results: Correlational analysis highlighted a significantly negative relationship between extraversion and agreeableness traits and all the demoralization dimensions. On the other side, neuroticism trait was significantly and positively correlated with the Demoralization Scale (p < 0.01). To understand the impact of these variables on quality of life (FACT-G), we performed a hierarchical multiple regression: in the final model, demoralization remained the strongest contributing factor (β = − 0.509, p < 0.001), followed by neuroticism (β = − 0.175, p < 0.001), spirituality (β = 0.163, p = 0.015), and Karnofsky index (β = 0.115, p = 0.012). Conclusion: Our data underlined how both the neuroticism trait and demoralization are correlated with a worst health status in terminal cancer patients, whereas spirituality is a protective factor. The study of personality may allow to better understand the inner patient’s experience and improve communication between patient and healthcare staff in order to build and apply better-tailored psychological treatment
A Psychological protocol for emotional assessment in women before and after beauty and wellness treatments.
No full texta new psychological assessment protocol has been used in a randomized controlled trial of women undergoing Beauty (Group 1 ) and Wellness (Group 2) treatment, with pre- and post-treatment psychometric evaluation
Sarcomatoid renal cell carcinoma with osteogenic differentiation and paraneoplastic hepatopathy in a dog, possibly related to human Stauffer's syndrome.
No full textSarcomatoid renal cell carcinoma is an uncommon tumour in human beings, and osteogenic differentiation is a rare feature. This report describes such a case in a male dog aged 8 years. The tumour, which showed extensive osseous metaplasia and a few necrotic areas, protruded into the renal pelvis, disrupting the renal capsule. Light microscopical and immunohistochemical examination revealed the epithelial nature of the tumour. Abnormal liver biochemistry, mild hepatocyte degeneration and the absence of histological evidence of metastasis suggested a paraneoplastic hepatopathy. © 2003 Elsevier Ltd. All rights reserved
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
