Relevance of nanotechnology in food processing industries
Full text linkNanotechnology is one of the innovative technologies including the production and / or control of structures, devices, or materials in which at least one dimension is from 1 to 100 nanometers. Nanotechnology has found wide application in many areas of life and economy, inter alia in: health care, pharmacy, agriculture, food processing, transport, energy, and information technology. This technology will revolutionize the agricultural and food industry through innovative tools for efficient processing, storage and packaging systems throughout the whole food supply chain. This paper covers the nanotechnology applications in food processing industries aimed at improving taste, texture, and consistency, or at developing polymers to improve food packaging, distribution, and shelf-life. Nano-sensors to detect food contaminants and 'smart' food development are also reviewed. Attention is also paid to the risk of using nanomaterials for human health and the environment
Nutritional Features of Biryani as The Basis for The Formation of An Entrepreneurial Mode in Biryani Market
No full textBiryani is a traditional spice-flavored rice-based delicacy containing meat and vegetables. In this paper, the preparation of Biryani, its composition, nutritional value and entrepreneurial possibilities are discussed. The nutritional value per 100 g of product of different types of Biryani is given. A diagram of the cooking procedure of this dish is presented. The Biryani market is compared with the fast food market. Attention is also paid to the most important economic factors that influence the consumer’s decision when buying food. These are: per capita income, price of the food relative to other products, as well as changes in the size and structure of the population. An additional advantage over the competition is outside the links between the restaurants and customers, business partners and suppliers. The purchase of this dish is most often associated with the processes of interacting with customers, with consumer safety, shaping their expectations, market information and customer behavior. This research suggests how establishing a modern Biryani market. Experimenting new variants of this dish and taking advantage of innovative digital solutions could be a strategy for promoting entrepreneurial development and even reducing youth unemployment
Selection of School and. Shop Assistant's Profession
No full textThe author discusses results of researches conducted among pupils in two vocational trade schools in Łódź in 1979. There are presented motives of selecting a given vocational school, attractiveness of the shop assistant's profession, professional plans of young people concerning their future work.
The author formulates a conclusion that it becomes necessary to develop interests of young people in the shop assistant’s profession in the course of their learning in a vocational school so that after completing it a bigger share of young people take up work in the acquired profession than it is the case today
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
