No full textENGLISH :
This study aims to examine the positive politeness strategies that are often used to show similarity, familiarity and respect. This research discusses the positive politeness strategies used by Jay Shetty in the Jay Shetty Podcast YouTube channel. This research focuses on two problem formulations, namely: (1) the types of positive politeness strategies used by Jay Shetty to male and female guest stars in talk show videos on the Jay Shetty Podcast YouTube channel, (2) the factors that influence the choices of positive politeness strategies used by Jay Shetty in talk show videos on the Jay Shetty Podcast YouTube channel. The data from this study are analyzed using the theory proposed by Brown & Levinson (1987) who argue that there are 15 positive politeness strategies. The method used to analyze this research is a qualitative approach with the content analysis method, the data in this study are taken from Jay Shetty's interviews with his guest stars that have been transcribed. The results showed that from the six most popular talk show videos on the Jay Shetty Podcast YouTube channel, it was obtained that Jay Shetty similarly uses 12 out of 15 (80%) positive politeness strategies, which means that Jay Shetty is very good at showing positive politeness to male and female guest stars when he communicated in his talk show, with a total of 327 data found. Based on Jay Shetty's three videos of talk shows with male guest stars, a total of 178 data were found, and from Jay Shetty's three videos of talk shows with female guest stars, a total of 149 data were found. Based on the analysis, the positive politeness strategy of exaggerate (approval, interest, sympathy with H) is the most dominant strategy used by Jay Shetty with a total of 102 data. Jay Shetty uses this strategy to show exaggerated approval, interest and sympathy to his guest stars to make them feel satisfied. In addition, Jay Shetty applies these strategies by factoring in Payoffs and Circumstances: sociological variables.

A novel multiblock immersed boundary method for large eddy simulation of complex arterial hemodynamics
No full textComputational fluid dynamics (CFD) simulations are becoming a reliable tool to understand hemodynamics, disease progression in pathological blood vessels and to predict medical device performance. Immersed boundary method (IBM) emerged as an attractive methodology because of its ability to efficiently handle complex moving and rotating geometries on structured grids. However, its application to study blood flow in complex, branching, patient-specific anatomies is scarce. This is because of the dominance of grid nodes in the exterior of the fluid domain over the useful grid nodes in the interior, rendering an inevitable memory and computational overhead. In order to alleviate this problem, we propose a novel multiblock based IBM that preserves the simplicity and effectiveness of the IBM on structured Cartesian meshes and enables handling of complex, anatomical geometries at a reduced memory overhead by minimizing the grid nodes in the exterior of the fluid domain. As pathological and medical device hemodynamics often involve complex, unsteady transitional or turbulent flow fields, a scale resolving turbulence model such as large eddy simulation (LES) is used in the present work. The proposed solver (here after referred as WenoHemo ), is developed by enhancing an existing in-house high-order incompressible flow solver that was previously validated for its numerics and several LES models by Shetty et al. (2010) [33]. In the present work, WenoHemoWenoHemo is systematically validated for additional numerics introduced, such as IBM and the multiblock approach, by simulating laminar flow over a sphere and laminar flow over a backward facing step respectively. Then, we validate the entire solver methodology by simulating laminar and transitional flow in abdominal aortic aneurysm (AAA). Finally, we perform blood flow simulations in the challenging clinically relevant thoracic aortic aneurysm (TAA), to gain insights into the type of fluid flow patterns that exist in pathological blood vessels. Results obtained from the TAA simulations reveal complex vortical and unsteady flow fields that need to be considered in designing and implanting medical devices such as stent graft
Energy requirements of adults.
No full textOBJECTIVES: To describe issues related to energy requirements of free living adults and discuss the importance of basal metabolic rate (BMR) and their relationships to total energy expenditure (TEE ) and physical activity level (PAL, derived as TEE/BMR) and to determine the influence of body weight, height, age and sex. DESIGN: Based on a review of the literature, this paper examines the variability in BMR due to methodology, ethnicity, migration and adaptation (both metabolic and behavioural) due to changes in nutritional status. Collates and compiles data on measurements of TEE in free living healthy adults, to arrive at limits and to compare TEE of populations with different life-styles. RESULTS AND CONCLUSIONS: The constancy of BMR and its validity as a reliable predictor of TEE in adults as well as the validity of PAL as an index of TEE adjusted for BMR and thus its use to categorise the physical activity pattern and lifestyle of an individual was confirmed. The limits of human daily energy expenditure at around 1.2 x BMR and 4.5 x BMR based on measurements made in free living adults have been reported in the literature. A large and robust database now exists of energy expenditure measurements obtained by the doubly labelled water method in the scientific literature and the data shows that, in general, levels of energy expenditure are similar to the recommendations for energy requirements adopted by FAO/WHO/UNU (1985). The review also confirms that metabolic adaptation to energy restriction is not an important factor that needs to be considered when recommending energy requirements for adults in developing countries
ROLE OF SEED LIPIDS IN ASPERGILLUS-PARASITICUS GROWTH AND AFLATOXIN PRODUCTION
No full textSeeds of crops with differing lipid content (groundnut (Arachis hypogaea L), paddy (Oryza sativa L), sorghum (Sorghum bicolor (L) Moench), cowpea (Vigna unguiculata L Walp) and green gram (Vigna radiatus L Wilczek)) were screened for their ability to support growth and aflatoxin B1 (AFB1) production by Aspergillus parasiticus NRRL 2999. Groundnut, with the most lipids, supported greatest AFB1 production. With all crops except for sorghum and paddy, powdered seed material (PSM) supported more AFB1 production than their respective defatted powdered seed material (DPSM). When A parasiticus was grown on Czapek Dox agar amended with PSM and DPSM of different seeds with differing lipid contents, A parasiticus colonies were always larger on PSM-than on DPSM-supplemented medium of the same seed. However, mycelial dry weight was only greater on media supplemented with groundnut, cowpea or green gram PSM. Growth and aflatoxin production by A parasiticus was also compared in Czapek Dox broth amended with seed coats, cotyledons and embryonic axes of groundnut kernels. The cotyledons of groundnut, with most lipids, supported the greatest production of AFB1. Apart from media supplemented with embryonic axes, PSM again supported more growth and AFB1 production than DPSM of the same portion of the kernel. Seed lipids thus seem important in determining growth and AFB1 production by A parasiticus

No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
