Knowledge and use of bee products in Lithuania /
Background/Objective: In recent years, there has been a growing public interest in natural products, including those derived from bees. While most scientific research on bee products has focused on their pharmacological properties, insufficient attention has been given to consumer knowledge, consumption habits and attitudes. The aim of this study was to estimate the popularity of use of different bee products and assess consumer knowledge about them in Lithuania. Methods: An online survey was carried out of the general adult population of Lithuania with 421 respondents included. Results: The study revealed that honey, beeswax and royal jelly were the best-known bee products, while bee venom was the least known one. Knowledge levels varied by age and occupation of respondents—older people and those working in pharmacy, healthcare, cosmetology, agriculture, beekeeping and food production showed better perception. Honey was most often used for treating colds (78.9%), prevention (78.1%) and reducing fever (65.3%). Dietary use of honey depended on demographic factors and was generally low—28.3% consumed it only a few times per year or less. For cosmetics, propolis was the most used product (34.2%). Conclusions: Older individuals and professionals in pharmacy, healthcare, cosmetology, agriculture, beekeeping and food production, demonstrated better knowledge of bee products. Although honey was rarely consumed as part of the diet, older people tended to use it more often than younger individuals. Men were more likely to use honey for treating digestive and circulatory issues and as an ingredient in food and beverages, whereas women were more inclined to use it for respiratory illnesses and cosmetic treatments
Sėklinių sklypų tinklo sukūrimas lietuvos vaistinių ir aromatinių augalų genetinių išteklių išsaugojimui in-situ.
Twenty six seed (genetic) sites were established for long-term in-situ conservation of medicinal and aromatic plant (MAP) genetic resources in Lithuania over the period 2006–2017. The sites vary in size from 0.4 to 38.0 ha with an average of 7.2 ha. Most of the sites (73%) occur in the existing protected areas. They represent 10 of 22 physical geographical areas of Lithuania and accommodate 120 priority MAP species, which is about 89% of the national priority list. Prioritization of MAP species was based on the monographs of European Pharmacopoeia, European Medicines Agency, World Health Organization as well as German Phytotherapeutic Monographs and other regional and national medicinal plant references. A concept was followed of the dual function and perception of food as medicine, and, vice versa, an approach based on a co-evolutionary relationship between human food and medicine. It was established that only 46 priority species, or 34% of the national priority list, were represented by five and more populations, which is considered as minimum for long-term in-situ conservation. The future conservation planning efforts should focus on at least 15 unrepresented species, 49 species represented at 1–2 sites each and 25 species represented at 3–4 sites each. The MAP site network should expand by covering preferably the remaining 12 physical geographical areas of the country
Hypericum perforatum morfologinis įvairavimas lauko kolekcijoje.
Variation of ten phenotypic characters was assessed among fifteen Lithuanian accessions of Hypericum perforatum L. of wild origin as well as Polish cultivar "Topaz" cultivated in the field collection of medicinal plants at the Institute of Botany. High variations were established within accessions in length and width of inflorescence and weight of raw material. It was established that the morphotypes vary very much within the accessions as well. The accessions No. 381, No. 419, No. 423, No. 424, No. 426 and No. 427 are adequate to the cv. "Topaz" and produce fairly long and wide inflorescences with high total yield of medicinal raw material
National network of genetic reserve sites for medicinal, aromatic plants and CWR conservation in Lithuania /
Vaistinių ir aromatinių augalų sėklinių (genetinių) sklypų įvertinimo Lietuvoje metodinės gairės.
The aim of the study is to discuss and establish tentative guidelines for the original selection and evaluation of genetic sites for in situ conservation of medicinal and aromatic plant genetic resources in Lithuania and provide baseline recommendations for their management and monitoring. The methodology applied is largely based on the one used in crop wild relative conservation in situ. Three groups of criteria, including species, site and threat assessment, are used on a 5-point evaluation scale to evaluate genetic sites, with ‘5’ representing the highest quality or state and ‘1’ representing the lowest quality or state. Top ten criteria are selected out of more than twenty those discussed for the application in genetic site evaluation. Four of these pertain to target species: species number and cover abundance (20% weight), number of red-listed species (10%), number of cultivated/ CWR species (10%), distinctive properties of populations (10%); two to site: area size (5%), protected area status (15%); and four to threat assessment: open site overgrowth with woody plant species (5%), mechanical damage of soil surface (5%), abundance of invasive non-native species (10%) and abundance of problematic native species (10%). Then, a weighted summing up is made to get an overall evaluation of a genetic site. For long-term conservation only sites scored not less than three points on average are recommended. An interpretation of final evaluation scores is also provided. Baseline recommendations for genetic site management focus on intervention measures, while those for monitoring - on periodicity of evaluation and some organizational aspects of implementation
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
