INFLUENCE OF CHEMOSENSORY IMPAIRMENT ON INTAKE AND LIKING OF A FUNCTIONAL DRINK IN UNDERNOURISHED INSTITUTIONALIZED ELDERLY PEOPLE
Age-related chemosensory impairments (i.e., reduction of taste and smell acuity) affect a large proportion of
the population older than 65 years. These conditions can affect overall health, quality of life and influence food appreciation and
intake. The knowledge about the relation between chemosensory perception and hedonic food liking in older people might
facilitate the development of effective strategies aiming to improve their nutritional wellbeing. Objectives: The key objective of this
study is to test the influence of a sensory compensatory strategy on liking and intake of a functional red fruit drink in
undernourished nursing home elderly people. Design: The research consisted of three main phases. In the first step the enrolled
subjects were classified on the basis of their taste and olfaction sensitivity; in the second step the sensory compensatory strategy,
aiming to counteract age-associated sensory losses and increase product pleasantness, was identified; the last step consisted of 14
days of exposure to each drink variant (standard and enhanced) to observe the effects of sensory modifications on liking and
intake. Setting: “Villa delle Querce” Clinical Rehabilitation Institute of Nemi (Rome- Italy). Participants: 76 elderly people (64-97
years). Results: Overall the prevalence of measured chemosensory impairments in this sample of institutionalized older adults was
very high (81%). The sensory modification strategy did influence significantly neither the intake nor liking in the elderly people.
Consistent with the findings of previous studies (3, 6, 24, 25) no significant correlation was found between sensory capabilities and
hedonic responses. Conclusion: These findings highlight that, in accordance to other studies (2, 3, 6-8), the role of sensory
compensatory strategies in increasing products appreciation and intake of institutionalized elderly people have been
overestimated
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
Effects of different organic and conventional fertilisers on flavour related quality attributes of cv. Golden Delicious apples
Abstract
The effects of the application of different organic and conventional fertilisers on some flavour quality attributes (aroma volatiles, sugars and organic acids) of cv. Golden Delicious apples were investigated by an experimental field trial in two harvest years (2010 and 2012). Through a balanced randomised block design, five organic fertilisation treatments (three different fertilisers at the same nitrogen dose, increase and fractionation of dose for one of the fertiliser) were compared to each other, to a conventional treatment based on a mineral fertiliser and to a non-fertilised control.
Fertilisation treatments significantly affected the level in fruits of several flavour related compounds, such as some aroma volatiles, sugars and organic acids, but few of these responses were consistent across the two harvest years and of remarkable size. Even when treatments gave place to marked differences in the soil mineral nitrogen level, this reflected in a limited impact on flavour related compounds in the fruit, the strongest effect being a 45% change in C6-aldehydes level. The different organic fertilisation treatments weakly affected the considered fruit quality attributes. Significant differences were observed for several sensory attributes between apples coming from different fertilisation treatments and characterised by a quite similar chemical profile
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
