Orthographic influences, vocabulary development and phonological awareness in deaf children who use cochlear implants
No full textIn the current study, we explore the influence of orthographic knowledge on phonological awareness in children with cochlear implants and compare developmental associations to those found for hearing children matched for word reading level or chronological age. We show an influence of orthographic knowledge on syllable and phoneme awareness in deaf and hearing children, but no orthographic effect on rhyme awareness. Nonorthographic rhyme awareness was a significant predictor of reading outcomes for all groups. However, whereas receptive vocabulary knowledge was the most important predictor of word reading variance in the cochlear implant group, rhyme awareness was the only important predictor of word reading variance in the reading level matched hearing group. Both vocabulary and rhyme awareness were equally important in predicting reading in the chronological age-matched hearing group. The data suggest that both deaf and hearing children are influenced by orthography when making phonological judgments, and that phonological awareness and vocabulary are both important for reading developmen

Rāgs Around the Clock: A Handbook for North Indian Classical Music, with Online Recordings in the Khayāl Style
No full textRāgs Around the Clock is a rich and vibrant compendium for the discovery and study of North Indian classical music. The theory and practice of rāg are explored through two interlinked resources: a handbook of essays and analyses offering technical, historical, cultural and aesthetic perspectives; and two online albums – Rāg samay cakra and Twilight Rāgs from North India – featuring khayāl singer Vijay Rajput and accompanists.Extracts from the albums are also embedded into the text to enhance learning and understanding. Each rāg is accompanied by a description of its chief characteristics and technical features, a notation of the song (bandiś) on which the performance is based, and a transliteration and translation of the song text. Distinctively, Rāg samay cakra also includes spoken renditions of each of the texts, helping non-Hindavi speakers to achieve the correct pronunciation.Sharing insights from both theory and practice, this collection draws on recent scholarship while also showcasing the vocal idiom – the gāyakī – of Vijay Rajput, a disciple of the late Pandit Bhimsen Joshi. It offers invaluable reading for students and researchers of Indian classical music, world music and ethnomusicology, and a rich repository for teacher and student practitioners of the khayāl vocal style. The combination of an aural and written exploration of rāg will appeal to anyone drawn to this form of music – whether newcomer, student (śiṣyā) or aficionado (rasika)
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
Genetic variation at the apolipoprotein B gene and associations with coronary heart disease and its factors.
No full textPhDCoronary heart disease (CED) is the major cause of mortality in Western societies.
The main risk factors are plasma lipoprotein concentrations, smoking, blood pressure and
family history. The effect of family history implies a genetic contribution to the aetiology,
support for which has also come from twin, and other heritability studies. The genetic
component of CHID may be studied by the candidate gene approach, whereby the genes of
products most likely to be involved in the processes leading to CHD, and in its risk factors,
are analysed. The plasma concentration of apolipoprotein (apo) B, the major protein
component of low density lipoprotein (LDL), is positively correlated with the risk of
developing CHD.
In this research, the gene for apo B was analysed for restriction enzyme fragment
length polymorphisms (RFLPs). A RFLP is caused by a sequence change in the DNA, and
results in length variation in the fragments. RFLPs for apo B have been shown to be
associated with CHD and the plasma concentrations of cholesterol, triglycerides and apo B
in some population studies. However, other studies have failed to confirm these relations.
The work described in this thesis was designed to overcome some of the problems which
niay have produced these inconsistencies. A random sample of 300 men, aged 49-65 years,
residing in South Wales was studied. RFLPs determined in these individuals were used to
generate genotypes and haplotypes (arrangements of specific alleles on a single
chromosome). Significant associations were found between some genotypes and some
haplotypes with altered concentrations of plasma total cholesterol and LDL cholesterol and
with risk of CHD and/or with obesity. Presence of Xbal site (X2X2 genotype) was
significantly associated with higher concentrations of plasma LDL cholesterol (p=0.0 19).
Absence of Mspl site (M 1) was associated with significantly elevated concentrations of
plasma total and LDL cholesterol (p < 0.05) by both the techniques of genotype and
haplotype analysis. EcoRl RFLP (absence of the site - El) was the minimum haplotype
necessary to detect a significant association with decreased plasma cholesterol

concentrations (p < 0.05). Genotypes generated from alleles defined by the Mspl-EcoRl
RFLPs were associated with significant variation in serum cholesterol concentration (p <
0.03), showing a stratification of concentration with the highest being associated with loss
of the Mspl site and the lowest with the presence of the EcoRl site. Both these RFLPs result
in charged aminoacid alterations, and lie close to the LDL receptor binding domain of apo
B. The minimum haplotype necessary for detection of apo B with CHD was Xbal-Mspl (p
< 0.05). The minimum haplotype associated with obesity was the RFLP pair Pvull-Xbal (p
< 0.05).
Further examination for mutations of the CpG dinucleotide which may influence
cholesterol metabolism was undertaken by screening around the putative LDL receptorbinding
domain (RBD) of the apo B gene. One variant was detected for aminoacid residue
3500 (Arg,,,,, 4 Gln) mutation, and two variants for aminoacid residue 3611 which also
corresponds to the MspI mutation (Arg,,, ,4
Gln)
Single‐Atom Quantum‐Point Contact Switch Using Atomically Thin Hexagonal Boron Nitride
No full textThe first report of a quantized conductance atomic threshold switch (QCATS) using an atomically-thin hexagonal boron nitride (hBN) layer is provided. This QCATS has applications in memory and logic devices. The QCATS device shows a stable and reproducible conductance quantization state at 1 center dot G(0) by forming single-atom point contact through a monoatomic boron defect in an hBN layer. An atomistic switching mechanism in hBN-QCATS is confirmed by in situ visualization of mono-atomic conductive filaments. Atomic defects in hBN are the key factor that affects the switching characteristic. The hBN-QCATS has excellent switching characteristics such as low operation voltage of 0.3 V, low "off" current of 1 pA, fast switching of 50 ns, and high endurance > 10(7) cycles. The variability of switching characteristics, which are the major problems of switching device, can be solved by reducing the area and thickness of the switching region to form single-atom point contact. The switching layer thickness is scaled down to the single-atom (approximate to 0.33 nm) h-BN layer, and the switching area is limited to single-atom defects. By implementing excellent switching characteristics using single-layer hBN, the possibility of implementing stable and uniform atomic-switching devices for future memory and logic applications is confirmed.11Nsciescopu
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
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
