Osmo and ionic regulation of black tiger prawn (Penaeus monodon Fabricius 1798) juveniles exposed to K+ deficient inland saline water at different salinities
No full textAn 11-day trial was conducted to investigate the osmoregulatory capacity (OC) and regulation of K+, Na+, Ca2+ and Mg2+ of Penaeus monodon juveniles when exposed to K+ deficient inland saline water (ISW) of four different salinities (5, 15, 25 and 35 ppt). The survival of juveniles showed a positive linear relationship (R2 ranging from 0.72 to 0.98) with salinity. At the end of the trial, juveniles were able to survive only in 5 ppt of ISW and showed no changes in OC when transferred from ocean water (OW) to ISW. Further, the OC of juveniles in 5 ppt of ISW was significantly different (P < 0.05) from the OC of juveniles exposed to 15, 25 and 35 ppt and exhibited strong serum K+, Na+, Ca2+ and Mg2+ regulation monitored over 16 h. In contrast, at 35 ppt, significant decrease (P < 0.05) in serum K+ and Mg2+ concentrations and accumulation of serum Na+ concentration occurred after 16 h of exposure to ISW. At higher salinity, an increase in serum Na+ concentration leads to an increase in the serum osmolality of the juveniles, which in turn causes decrease in the OC of the juveniles. The results of this study suggest that K+ deficiency in ISW has a negative effect on survival, OC and the ability of P. monodon juveniles to regulate serum Na+, K+, Ca2+ and Mg2+ concentrations. These effects are compounded as salinity increases
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
MODEL CORPORATE SOCIAL RESPONSIBILITY (CSR) BERBASIS AGRIBISNIS PANGAN (STUDI KASUS DI PT. SMART WILAYAH KALIMANTAN TENGAH)
Get PDFThere is still a conflict of interest in land use, causing land used by farmers for food development to be included as HGU PT. SMART. The research aims to (1) find out the food development practices carried out by PT. SMART, (2) knowing the advantages and weaknesses of food development, (3) knowing the response of stakeholders to food development, (4) analyzing the formulation of CSR models for oil palm plantations based on food agribusiness. The results showed that agribusiness-based PET practices since planning, implementation, and marketing are entirely carried out by farmers. Farmers also individually and in groups conduct monitoring and evaluation, both on farming technicalities, group management, and the implementation of PET as a whole. The advantages and disadvantages of PET are the advantages of implementing PET PT. SMART mainly comes from the direct involvement of farmers in all work and management of farms, weaknesses in the implementation of PET PT. SMART consists of basic work of PET participants, difficulties in procuring saprodi after the crop starts to produce, the inability of farmers because while doing other work, productivity is quite low compared to pilot companies, management of farmer groups, and related government agencies have not been involved sustainably. Stakeholder response to PET practices has generally been good, but it is recognized that increasing the income of PET farmers is not accompanied by the ability of communities to manage their incomes. The formulation of the CSR model of PT. SMART based agribusiness food is (1) CSR of PT. SMART based on food agribusiness uses a model of partnering with other parties, namely partnering with farmers, government and universities, (2) empowering farmers in the CSR model of PT. SMART based on food agribusiness uses a collective farming group approach, while farming uses an integrated farming system. 
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
