Market sustainability analysis of jenny milk cosmetics
Full text linkA quantitative market analysis was carried out to deepen the knowledge on some qualitative and quantitative aspects of jenny milk and cosmetics and, successively, a survey was carried out to study the influence of packaging on consumer liking. The first analysis was conducted using the quantitative method by interviews with a one to one questionnaire, consisting of 18 questions. In the second survey were interviewed 300 people with a questionnaire divided into two perception areas: of packaging paper, and of packaging communication. Results showed that 67.8% of consumers had familiarity with jenny milk, but only 19.5% knew cosmetic properties of this product. The panel expressed a low expenditure propensity toward the proposed cosmetics. For these products, the study on packaging identified a type of matte paper as the favorite by consumer. Moreover, panel judged the icon of donkey and naming Asinella as the most persuasive
ANALYSIS OF THE DEGRADATION OF THE AQUAPORIN ATPIP2;1 IN ARABIDOPSIS THALIANA
No full textAquaporins are highly conserved membrane proteins that facilitate the water transport across the biological membranes. In this
work we study the degradation process of Plasma membrane Intrinsic Proteins (PIPs), in particular, the isoform AtPIP2;1, in
Arabidopsis thaliana roots. We expressed AtPIP2;1-GFP and AtPIP2;1-photoactivable GFP (paGFP) under the control of a 35S
CaMV or a PIP2;1 native promoter in a k.o. pip2;1 line. The intensities of the fluorescence and the subcellular localization were
monitored by means of epifluorescence and confocal microscopies. First, roots expressing the GFP constructs were treated with
cycloheximide (CHX), a protein synthesis inhibitor. After 24 h, no significant difference compared to a control treatment was
observed; experiments with the paGFP constructs indicate the same tendency. To make sure that the CHX treatments efficiently
inhibited the protein synthesis, we monitored the signal of Aleurin-GFP fusion expressed in Arabidopsis plantlets. CHX
treatment provoked a tremendous decrease of fluorescence signal, indicating the efficiency of the CHX. Next, we analyzed the
effect of H2O2 treatments, and observed a slight but not significant decrease of the signal. Confocal microscopy, allowed us to
observe that AtPIP2;1 constructs labeled intracellular dots, similar to those previously described in our laboratory. Lastly,
treatments with 1 μM NAA, a synthetic analog of auxin, did not provoke any decrease of the intensity of the signal; we obtain a
similar result with 1 μM IAA. Also, confocal microscopy observations showed a strong intracellular labeling. Altogether, these
results allowed to conclude that AtPIP2;1-GFP construct is intrinsically very stable in the plasma membrane, in resting
conditions. Treatment with H2O2 did not destabilize AtPIP2;1-GFP construct in the plasma membrane. In the contrary, auxin
maintain the basal level of AtPIP2;1-GFP construct and provoke a strong relocalisation in intracellular compartments
Il latte d'asina nella cosmesi: indagine conoscitiva tra innovazione e tradizione
Full text linkNell’ambito di una più ampia ricerca inerente alla Conservazione della Specie Asinina e la salvaguardia delle aree marginali tramite la valorizzazione in prodotti di onocosmesi è stata svolta una prima indagine quantitativa di mercato.
Il latte di asina, oltre ad essere un eccellente sostituto del latte umano, è anche un buon costituente di base per la preparazione di cosmetici. Infatti, è un tensore naturale, ricco in vitamine e sali minerali essenziali per la rigenerazione delle cellule. Lo studio, effettuato in Basilicata, ha avuto come obiettivo la conoscenza di alcuni aspetti quali-quantitativi del prodotto.
L’indagine ha evidenziato la propensione di oltre il 75% dei consumatori intervistati all’acquisto di cosmetici innovativi prodotti con sostanze naturali
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
