Mantenere in vita un neonato estremamente prematuro : possibilità, aspetti bioetici, coinvolgimento dell'ostetrica
No full textGli attuali progressi nell’assistenza neonatale hanno notevolmente migliorato la prognosi e le probabilità di sopravvivenza dei neonati in condizioni critiche o molto pretermine ed hanno di fatto modificato il concetto stesso ed i limiti della così detta “vitalità”. Tuttavia, in alcune circostanze, quando il decesso del bambino può essere solo temporaneamente posposto, a prezzo di gravi sofferenze, o quando la sopravvivenza si associa con gravissime disabilità permanenti ed una vita intollerabile per il bambino e la sua famiglia, potrebbe non essere appropriato utilizzare tutti i supporti artificiali della terapia intensiva neonatale. In tali circostanze la limitazione dei trattamenti intensivi (“non inizio” o “sospensione”), peraltro invasivi e dolorosi, potrebbe rappresentare una alternativa più umana e ragionevole. In questa tesi vengono esaminati e discussi i principi etici che sottendono tali difficili decisioni, le situazioni più frequenti in cui esse possono essere prese in considerazione, il ruolo dei genitori nel processo decisionale e quali sono le opinioni e i comportamenti delle ostetriche. Tutto questo mettendo a confronto le Evidence Based Medicine con gli ultimi dati incoraggianti raccolti presso la Clinica Mangiagalli di Milano. Lo studio pertanto si basa su una raccolta epidemiologica che mostra grandi differenze quantitative riguardo alla sopravvivenza tra i neonati nati nell’anno 2011 e 2012 con, però, non indifferenti e sottovalutabili esiti in termini di qualità di vita.
Il coinvolgimento dell’ostetrica è parte determinante della buona riuscita di una comunicazione efficace e olistica alla coppia. Viene posto loro un questionario riferito alla propria esperienza lavorativa ineluttabilmente influenzata da principi, valori e morale legati all’essere donna e, in certi casi, madre
Membrane- and cell wall-associated heat shock proteins in two genotypes of barley seedlings
No full textThe heat-shock (HS) response of two genotypes (cv. Onice winter type, and cv. Georgie, spring type) of barley (Hordeum vulgare L.) was compared. Protein synthesis was markedly reduced in cv. Onice was higher than in cv. Georgie. The pattern of cytosolic, membrane and cell wall HSPs was analysed by SDS-PAGE in coleoptiles and roots of the two genotypes. Differences and similarities in coleoptiles and roots of the same genotype and between the two genotypes were observed. In roots of the genotype Onice, LMW and HMW HSPs isolated from the cytosol, membranes and cell walls were resolved into a diverse array of polypeptides by two-dimensional gel electrophoresis. Present results confirm the de novo synthesis of cytosolic and membrane HSPs, and demonstrate, for the first time, their presence in cell walls
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
Running development by means multilateralism in 6 years old pupils.
No full textIntroduction
The physical education at school can be help the children to improve their gross motor skill through an oriented multilateral activity. Without use drill as the only way to improve skill it’s possible differentiate the physical education activity to improve a particular objective.
Aims
The aim of this study was an attempt to investigate the possibility to improve run in children aged 6 by means oriented multilateral activity. The study was realized during the normal physical education in primary school in a period of 4th months.
Methods
The participants were 40 children, aged 6, from Italian primary school. Ten meter run speed test was applied to estimate the velocity and the steps frequency. The collected material was analyzed statistically. Wilkoxon Test was used to demonstrate the data significant.
Results
The obtained results show that multilateral activity had improved run motor skill in the sperimental group. The data analysis didn’t show a significant improvement in speed both in sperimental and control group instead it emphasize a substantial difference in the steps frequencythat decreasing in the sperimental group as a significant index of better motor control in steps frequency.
Conclusion
Oriented multilateralism, in physical education at scool, is a good way to help children to improve their gross motor skill. Without drill or special trainig its possible to stimulate the development of specific motor pattern who can be transfered in sport activity
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
