Technological development in mechanical ventilation.
No full textPURPOSE OF REVIEW: Innovative modes of mechanical ventilation, mainly based on complex closed loop technologies, have been recently developed and are now available for clinical use.
RECENT FINDINGS: Proportional assist ventilation with load-adjustable gain factors and neurally adjusted ventilatory assist are innovative modes of mechanical ventilation delivering a level of assistance proportional to the patient's effort, thus improving patient-ventilator synchrony and potentially representing a real clinical advantage. Adaptive support ventilation is a ventilatory mode delivering assisted (pressure support ventilation-like) or controlled breathing cycles (pressure-controlled-like), related to a minute ventilation target set by the clinician and on automated measurements of the patient's respiratory mechanics. Noisy pressure support ventilation, finally, is a recently described experimental evolution of pressure support, with some improvement potentials, but no clinical application till now.
SUMMARY: The recently reported results with proportional assist ventilation with load-adjustable gain factors, neurally adjusted ventilatory assist, and adaptive support ventilation are, till now, mainly based on preliminary physiologic and clinical studies; although they seem to be promising, suggesting that closed loop-based modes could represent a real innovation in the field of mechanical ventilation, further clinical evaluation is needed before their widespread diffusion into clinical practice
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
Sistema prisional de Manuas/Am e os projetos de ressocialização: aplicabilidade dos projetos ressocializadores
Full text linkBrazil, like other countries, has a prison system, which has been one of the biggest
reflections of existing social problems. According to the 2015 incarceration map, 38%
of the Brazilian prison population is made up of inmates, 61% are convicted and 1%
are detained for security reasons. Highlighting the precariousness of the criminal
justice system, highlighting the incarceration and condemnation policies, mainly
opening up the social divisions generated in Brazilian society and emphasizing the
relationship between class, race and gender. The objective of the research was to
analyze the projects developed in the Male Provisional Detention Center, for which the
following specific objectives were drawn: to discuss the prison system and the Male
Provisional Detention Center in the city of Manaus; to identify the projects carried out
at the Male Provisional Detention Center in Manaus, the actions developed with the
re-educators; to know the impacts that were generated in the experience between the
inmates and their families through the data presented in the Justice Analysis Council.
The present work is configured as a documentary and bibliographical research, whose
method approaches an approach to historical-dialectical materialism whose main
purpose is to present, identify and discuss the socio-historical aspects, and the
material and dialectical conditions of the study in question. . In view of the results
obtained, it is identified that the social reintegration projects directly interfere in the way
that the re-educated will act in society, in addition to the importance of these projects
in the relationship with their families.O Brasil, assim como outros países, possui um sistema prisional, que tem se mostrado
um dos maiores reflexos dos problemas sociais existentes. Segundo o mapa do
encarceramento de 2015, 38% da população carcerária brasileira é composta por
internos, 61% são condenados e 1% são detidos por questões de segurança.
Destacando a precariedade do sistema de justiça criminal, evidenciando as políticas
de encarceramento e condenação, principalmente escancarando as divisões sociais
geradas na sociedade brasileira e enfatizando a relação entre classe, raça e gênero.
O objetivo da pesquisa foi analisar os projetos desenvolvidos no Centro de Detenção
Provisória Masculino para isso foram traçados os seguintes objetivos específicos:
discorrer sobre o sistema prisional e o Centro de Detenção Provisória Masculino na
cidade de Manaus; identificar os projetos realizados no Centro de Detenção Provisória
Masculino de Manaus as ações desenvolvidas com os reeducandos; conhecer os
impactos que foram gerados na vivência entre os reeducandos e as suas famílias
através dos dados apresentados no Conselho de Análise de Justiça. O presente
trabalho configura-se como pesquisa documental e bibliográfica, cujo o método
abordado uma aproximação com o materialismo histórico-dialético que tem como
principal finalidade apresentar, identificar e discutir os aspectos sócio-históricos, e as
condições materiais e dialéticas do estudo em questão. Diante dos resultados obtidos
identifica-se que os projetos de reinserção social interferem diretamente na forma que
o reeducando atuará em sociedade, além da importância desses projetos na relação
com suas famílias.4Si

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
