Study of metal surfaces in operando conditions by means of near-ambient-pressure scanning tunneling microscopy
Full text linkTitle: Study of metal surfaces in operando conditions by means of near-ambient- pressure scanning tunneling microscopy Author: Petr Dlabaja Department: Department of Surface and Plasma Science Supervisor: RNDr. Peter Matvija, Ph.D., Department of Surface and Plasma Science Abstract: The thesis covers investigation of monocrystalline surfaces of metals Cu(111) and Pt(111) in high pressures. These surfaces were exposed to oxygen and carbon monoxide gasses of pressures between 1 × 10−10 mbar and 5 mbar. Changes in the structure of the surfaces was monitored using scanning tunneling microscopy, low-energy electron diffraction and X-ray photoelectron spectroscopy. Acquired results showed that reactive gasses at pressures ≈ 5 mbar affect the structure of the surfaces more prominently than the same gasses of lower pres- sures. The surface of Cu(111) at room temperature and 5 mbar pressure of O2 strongly oxidized. The surface of Pt(111) at pressure 5 mbar of gass O2 oxidized only locally, under the influence of the STM tip. Increased pressure of carbon mo- noxide induces creation of nanometric clusters on the surface of Cu(111), which agglomerate into small islands. These islands are distributed evenly on the whole surface of Cu(111). In contrast increased pressure of carbon monoxide mainly changes the shapes of..
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
The Project of Integrating People with Physical Disabilities into the Labour Market in Karviná District
No full textOsoby zdravotně postižené jsou často vyloučeny na okraj společnosti, proto patří mezi ohrožené skupiny obyvatel. Jedním z důvodů jejich vyloučení je neschopnost uplatnit se na trhu práce. I přes rozvíjející se sociální cítění vyspělých států je nutná zvýšená ochrana zdravotně postižených osob skrze veřejný sektor jako prevence sociálně patologických jevů ve společnosti spojených s jejich nezaměstnaností. Okres Karviná se pro svoji vysokou nezaměstnanost a horší zdravotní stav obyvatelstva stal objektem práce. Cílem je zmapování problematiky zdravotně postižených osob a navržení projektu podpory jejich zaměstnávání v okrese Karviná. První část práce je rešerše české i světové literatury věnující se problematice zaměstnávání zdravotně postižených osob. Další částí je statistická analýza získaných dat vztahující se k problematice prezentována pomocí tabulek, grafů a rozborů. Výsledkem práce je shrnutí struktury registrovaných nezaměstnaných se zdravotním postižením, identifikace slabých míst jejich zaměstnávání v okrese Karviná a projekt podpory jejich zaměstnávání. Přínosem pro praxi je zjištění nedostatečně aktivity kontaktních míst veřejné správy a nepostačující kapacita neziskových organizací v regionu otvírající cestu pro zlepšení. Přínosem pro vědu je shrnutí nejednotnosti definic zdravotního postižení dávající prostor ke hledání společné evropské definice. Diplomová práce by mohla toto téma rozšířit o strukturu zaměstnaných osob se zdravotním postižením a podrobněji zanalyzovat zdravotně postižené uchazeče o zaměstnání k identifikaci hlavních důvodů jejich nezaměstnanosti.The physically disabled are ofttimes socially marginalised, and thus are among the vulnerable groups of population. One of the reasons for this marginalisation is their inability to integrate into the labour market. No matter how good the social conscience of the developed countries is, enhanced protection of the physically disabled is needed; preferably through the public sector as the socio-pathological phenomena prevention connected with their high unemployment rates. And that is exactly the reason I have chosen Karviná district as the area of my research the below average health conditions of the population and high unemployment rates. My aim was to uncover the most serious issues people with physical disabilities have to deal with, and to design a project of integrating them into the labour market in Karviná district. In the first part of my thesis I am researching the specialised literature, both Czech and foreign, dealing with the issue of employment of the physically disabled. In the second part I am analysing the data acquired in the research and presenting them via a number of tables, charts and analyses. As a result, I have summarised the structure of the physically disabled that are registered as unemployed, identified the weaknesses of the employment issues in Karviná district, and outlined the project of their integration. Put into practice, I have pointed out the lack of activity the contact points under the Public Administration are doing; and the insufficient capacities of the NPOs operating in the district that are supposed to improve the situation. From the scientific point of view, I have summarised the inconsistent definition of the term "the physical disability", which can help in unifying of the definition for European purposes. My diploma thesis can be extended by a list of the physically disabled that are unemployed and by an analysis of the main reasons for their unemployment.Ústav regionálního rozvoje, veřejné správy a práv
The Marketing Support Draft of the Orthopaedic Ward at Karviná-Ráj Hospital
No full textVeřejné zdravotnické organizace jsou zásadně znevýhodněny centralizací lukrativních výkonů a silnějším tlakem na dosahování ekonomických cílů v zařízeních soukromé sféry. Z těchto důvodů se v okrese Karviná s vysokou nezaměstnaností a horším zdravotním stavem obyvatel stala objektem této práce Nemocnice s poliklinikou Karviná-Ráj, příspěvková organizace Moravskoslezského kraje.

These are the reasons Karviná-Ráj Hospital is the subject of this thesis; along with the high rate of unemployment and lower overall health conditions in the Karviná region. The first part is divided into two halves - one deals with the comparison of marketing environment in general and in healthcare, the other deals with marketing promotion in general and in healthcare - both described and based on research of Czech and English bibliography. The second part of the thesis shows the analysis of the related data and graphs with commen-tary. The outcome of the thesis is a detailed breakdown of Karviná-Ráj Hospital's market-ing environment, focusing mainly on the Orthopaedic ward, including the SWOT analysis. The project of The Marketing Support Draft of the Orthopaedic Ward at Karviná-Ráj Hos-pital is included at the end of the thesis. The science contribution of this thesis is the summary of incoherent approaches and analyses of the marketing environment and identifying further fields of research of healthcare organisations promotion. The practical contribution of the thesis is marking the insufficient marketing activities of Karviná-Ráj Hospital.Ústav managementu a marketing
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
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
