Organizational Security Processes and Crisis Management in the Knowledge Society
Full text linkInformační a komunikační technologie (ICT) tvoří součást infrastruktury většiny moderních organizací ve všech sektorech ekonomiky a jejich popularita neustále vzrůstá s novými produkty a snadnou dostupností také u spotřebitelů. ICT organizacím pomáhají plnit operativní i strategické cíle, definované v podnikových dokumentech, a jsou dnes již natolik důležité, že některá odvětví jsou podmíněna jejich bezchybnou funkčností a nepřetržitou dostupností, namátkou algoritmické a vysokofrekvenční obchody, elektronická tržiště, energetika, vojenství a zdravotnictví. Finanční, hmotné a lidské ztráty, které byly v poslední době zaznamenány dokazují neplatnost výše zmíněných předpokladů. Autor se domnívá a předpokladem této disertační práce je, že úzkým místem jsou především zaměstnanci a jejich chování. Zajištění ICT bezpečnosti je proto úkolem, na němž by se měli svým přístupem a chováním podílet všichni členové organizace. Dizertační práce je proto zaměřena na oblast bezpečnosti ICT z pohledu organizace i uživatele. Po rešerši sekundárních literárních zdrojů jsou formulovány předpoklady pro výzkumnou část, jež nejprve zhodnotí současný stav. Výstupy pak budou základem pro tvorbu modelu a doporučení, zajišťujících zvýšení bezpečnosti ICT a uživatelů, přicházejících s nimi do kontaktu a považovaných útočníky za cenný zdroj informací. Dizertační práce představí procesní model ICT governance integrující poznatky z výzkumné části. Také formuluje řešení pro hlavní aspekty organizační bezpečnostní politiky, například BYOD management, vzdělávání zaměstnanců, a zabezpečení infrastruktury spolu se správou hesel a nejlepšími praktikami v těchto oblastech. Výsledkem implementace tohoto modelu do praxe by měl být podnik s politikou reflektující existující i nastupující hrozby, a vzdělaní, na bezpečnost orientovaní zaměstnanci.Information and Communication Technology (ICT) forms infrastructure basis of most modern organizations in all economic sectors and has become more popular with individuals via new products and its ubiquitousness. Companies use ICT to fulfill both operational objectives and strategic goals, outlined in their fundamental documents. Nowadays, whole industries including algorithmic and high-frequency trading, online retailing, energy industry, military, and health care all assume uninterrupted ICT functionality and continuous availability. The repeated financial, material, and human losses that have occurred recently demonstrate this status should not be taken for granted. It is the author's belief and the focus of this dissertation that the primary cause for these losses is people, and their actions. Hence, each employee should strive to minimize threat exposure. The doctoral thesis deals with corporate- and user-centric ICT security. Based on evaluation of secondary sources, assumptions for the research part will be formulated by first assessing the current state. The research output will then help formulate recommendations to promote increased security of ICT and users coming into contact with sensitive electronic assets whom the attackers consider a valuable source of information. The ICT security governance model in chapter nine articulates recommendations for major aspects of organizational policies such as BYOD management, employee training, infrastructure hardening, and password management which are discussed and best practices devised. The result of implementing the model should be an organization capable to face existing and novel threats, and educated, security-conscious employees.Ústav statistiky a kvantitativních meto
Modern Theory of Information – Structured and Knowledge Based System Design
Full text linkInstructional text Modern Theory of Structured Information and Knowledge-Based System Design general part and a special part provides basic and necessary scope of knowledge of modern method design. The content is adapted for easier study the theory and the examples based on a formal method and knwoledge-based method. The objective of the author was to prepare teaching texts for doctoral students from UTB FAI in Zlín which provides the necessary knowledge in the subject of Modern Theory of Structured Information and Knowledge-Based System-Design. Main attention was paid to Method Common-KADS, which today is the European standard for design KBS and formal method Event-B for mathematical modeling and proving complex systems
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
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
