Going Beyond Counting First Authors in Author Co-citation Analysis
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
Variations on the Author
No full text“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
ISOLATION AND IDENTIFICATION OF A BOVINE RESPIRATORY SYNCYTIAL VIRUS IN CZECHOSLOVAKIA
No full textAbstract PospiSil, Z., J. MenSik, L. Vali<!ek: Isolation and Identification of a Booine Respiratory Syncytial Virus in CzechoslOfJakia. Acta vet. Bmo, 47, 1978: 79-86. A bovine respiratory syncytial virus (RSV) was isolated in primary foetal bovine kidney cell cultures from an outbreak of acute respiratory disease in a herd of feedlot cattle. The cytopathic changes developed slowly with large multinucleated syncytia being regularly observed only after 5 to 7 passages. The isolate was identified by virus--neutralizatjon and immunofluorescence tests and demonstrated by electron microscopy. Of three serologically negative calves infected experimentally with the virus, two developed mild respiratory disease and all three animals had specific antibodies in their sera.

Využití sociálních médií v B2B prodeji
No full textTato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce
Growth of compact layers at the interfase. V Adsorption properties of difenzoquat herbicide (1, 2 - dimethyl - 3, 5 - diphenyl pyrazolium.
No full textThe adsorption properties of 1,2-dimethyl-3,5-diphenyl-pyrazolium cation (difenzoquat) on the mercury electrode in aqueous medium are given. Strong adsorption is detectable at concentrations below 10(-6) mol/l and in a wide potential range. The time dependence of the electrode impedance indicates the formation of a compact film controlled by nucleation/growth phenomena. Under specific conditions the film has a fractal character connected with the existence of a constant phase element. An adsorptive stripping method can be worked out for its sensitive determination
TeX v jednoduchém unixovém prostředí
No full textsummary:Při ladění TeXového dokumentu potřebujeme mnohokrát opakovaně pouštět TeX, podívat se, jak dopadl výsledek v prohlížeči DVI nebo PDF souboru, mrknout na výpis TeXu na terminálu, podívat se případně do logu a celou činnost opakovat. V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper
Double-layer effects and distance dependence of electron transfer in reduction of nitro aromatic radical anions
No full textThe first example of the effect of an electric double layer on the reduction of electrochemically generated radical
species is reported. The anion radical of methyl 5-(2,4-dichlorophenoxy)-2-nitrobenzoate (pesticide bifenox) is
electrochemically reduced in acetonitrile to a phenylhydroxylamine derivative in a process involving three electrons.
This heterogeneous reaction is strongly influenced by the concentration and nature of the cation of the indifferent
electrolyte. Depending on the type of tetraalkylammonium cation, the redox potential changes by 0.45 V. The kinetic
parameters were obtained for five tetraalkylammonium hexafluorophosphate salts. The Frumkin correction, which
assumes that the outer Helmholtz plane coincides with the reaction site, was applied to kinetic data of the radical anion
reduction. The correction of the apparent rate accounted for the observed effect only in the case of tetramethylammonium
salt. The presence of higher tetraalkylammonium homologues causes deviations from the predicted dependence of
the electron-transfer rate on the æ2 potential of the outer Helmholtz plane. Hence, the nature of the cation of the
electrolyte exerts a further effect extending beyond the electrostatic repulsion only. The corrected rate of electron
transfer decreases exponentially with increasing size of the alkyl chain of the indifferent electrolyte cation in the order
methyl > ethyl > propyl > butyl > hexyl. The rate decay is characterized by an exponent â ) 0.83. This confirms
that the reaction plane for the reduction of the bifenox radical anion is different for each electrolyte. Due to this fact
the Frumkin correction cannot fully account for the observed dependence of the heterogeneous rate on the solution
composition. The observed effect is not specific to the bifenox radical. A similar influence of the concentration and
nature of the cation of the indifferent electrolyte was observed for other nitro compounds, namely, nitrobenzene,
nitrobenzoate, and nitrofen
