La ricerca di base può fornire gli strumenti per la comprensione e lo sviluppo dell'omeopatia
No full textA ventiquattro anni di distanza dall’acceso dibattito suscitato dalla pubblicazione dei risultati ottenuti dal gruppo di ricerca di Benveniste e nonostante la grande quantità di articoli scientifici apparsi su riviste internazionali, l’idea che le “ultra-low doses” e le alte diluizioni (HD), tra cui i medicinali omeopatici, possano evidenziare un’attività biologica e farmacologica rimane tuttora “incredibile” per la cosiddetta scienza accademica. Tale scetticismo, che non tiene in considerazione la sempre maggiore diffusione della pratica omeopatica e l’alto livello di soddisfazione dei pazienti, si basa essenzialmente sul fatto che le HD sono soggette ad un processo di diluizione seriale che porta a bassissimi livelli, spesso non misurabili, del principio attivo. Benché il meccanismo d’azione non sia stato ancora del tutto chiarito, le conoscenze su questo argomento “di frontiera” vanno rapidamente consolidandosi, con notevoli implicazioni non solo per la farmacologia, ma anche per la biologia, la fisica e le scienze agrarie ed ambientali.
Il XXVI convegno annuale del GIRI (Gruppo Internazionale di Ricerca sull’Infinitesimale), svoltosi a Firenze il 20-22 settembre nel contesto dell’ECIM 2012 (5° Congresso Europeo di Medicina Integrata), è stato organizzato dai nostri gruppi di ricerca dell’Università di Bologna e Verona. Tale congresso ha documentato questo avanzamento delle conoscenze con la presentazione di un nutrito numero di relazioni, tutte di elevata qualità scientifica, di cui alcune particolarmente significative sono compendiate in questa breve rassegna. Il programma del convegno è stato organizzato attorno a quattro assi principali: 1) caratteristiche fisico-chimiche delle HD e ruolo della dinamizzazione, 2) omeopatia e piante: studi in vitro, in planta ed in campo, 3) studi osservazionali ed evidenze cliniche e veterinarie, 4) modelli di laboratorio
Incompletezza e libertà
No full textIl recente tentativo di Paolo Bellavite e Mario Zatti di comparare la libertà umana con le dinamiche caotiche è discusso criticamente in questo saggio che, in tre punti, traccia una precisa distinzione tra causa in senso fisico e causa in senso ontologico, indicando le differenti implicazioni di una teoria secondo che vi si applichi una prospettiva ontologica o epistemologica
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
Basic research in homeopathy and ultra-high dilutions: what progress is being made?
Full text linkThis report summarises the latest research developments in the field of high dilutions and homeopathy, as presented at the GIRI symposium of the leading international organisation of scientists in this field, in Florence, Italy in September 2012. The scientific community's early scepticism concerning the possible biological and pharmacological activity of highly diluted solutions, is giving way to a more open-minded attitude that no longer obstructs critical and experimental investigations in this emerging field of biomedicine
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
