The role of leadership in managing digital transformation: A systematic literature review
Get PDFDigital transformation should not be seen as a time-bound project, but rather as a process that needs to be continuously improved and managed over time. In the absence of leadership, digital transformation will occur spontaneously in an organisation, but it is necessary to monitor and manage the process itself to achieve the goal and establish a digital organisation. A person who leads the digital transformation must possess the appropriate competencies. Leadership competencies, especially the combination of digital and human skills, are crucial to the development and success of the digital transformation process. The authors of this article identify a vaguely described process of digital transformation as the main research problem, highlighting the need for the systematisation of leadership competencies necessary for effective digital transformation management. In this regard, the research objectives are to define and describe the process of digital transformation and identify the leadership competencies necessary for successful management of the digital transformation process. In order to achieve the objectives of the paper, a systematic literature review was conducted for the period 2001–2022 and 90 papers were identified based on the criteria outlined by the Web of Science and Scopus index databases. The identified papers were then analysed from the aspect of defining digital transformation, the activities of the digital transformation process, and the characteristics of digital leadership. Following a thorough analysis of the selected literature, the paper provides a comprehensive definition of digital transformation, proposes a framework for its management, and analyses the key competencies of digital transformation leaders (digital leaders), which together make up the paper’s main contribution. The paper can be used not only as a starting point for future research in this area, but also as initial guidelines for the implementation and management of the digital transformation process. The systematic literature review conducted has certain limitations. Only two, albeit the largest, citation databases were searched, and only papers in English were identified. The established framework should be verified and expanded through empirical research
Metodické materiály typu Neposedové jako nástroj pro rozvoj schopnosti řešit slovní úlohy
No full textČlánek představuje netradiční typ slovních úloh a metodické materiály, které nabízí konkrétní způsoby, jak s těmito úlohami pracovat v hodinách matematiky a českého jazyka. Cílem metodických materiálů typu Neposedové je umocnit potřebu žáků vnímat jazykovou i kontextovou rovinu slovních úloh, vyvolat potřebu argumentovat a využívat při řešení reálných zkušeností. Zadání slovních úloh přirozeně vybízí žáky k experimentování, mají tak možnost objevovat nové řešitelské strategie. Na základě tří konkrétních úloh provedeme čtenáře celým procesem práce se slovní úlohou, reflektujeme žákovská řešení a zkušenosti učitelů z prvních pilotáží
A pupil with dyslexia and his difficulties with multiplication of natural numbers
No full textCílem článku je představit na vybrané případové studii potíže, se kterými se mohou žáci 1. stupně se specifickými poruchami učení potýkat v matematice, a poukázat na to, jak může být pro ně náročné zvládnout operaci násobení přirozených čísel v oboru malé násobilky. Jedná se o problematiku z oblasti didaktiky matematiky a v článku ji níže uvádíme do souvislosti se specifickými poruchami učení. Vybraná případová studie ilustrující tuto problematiku by se mohla stát inspirativní a užitečnou pro učitele 1. stupně ZŠ a konzultanty v oblasti vzdělávání.The article aims to present, based on a selected case study, the difficulties that 1st-grade students with specific learning disabilities may encounter in mathematics and to point out how it can be challenging for them to master the operation of multiplying natural numbers in the area of small multiplication tables. This is a known issue in mathematics education and the article relates it to specific learning disorders. A selected case study illustrating this issue could be inspiring and useful for elementary school teachers and educational researchers

Exploring travel agencies customers’ loyalty motives throught machine learning analysis
Get PDFThis article focuses on identifying the directions of changes in the decision-making process of purchasing package travels and the motives determining this purchase, as well as the impact of these motives on the affective, behavioral and global loyalty of travel agency customers during the COVID-19 pandemic. To achieve the research goal, a literature review and field research were conducted. In the case of secondary sources, the content analysis method was used to examine them, while data from primary sources (N = 1,508) were collected using an indirect survey technique (CAWI). The data analysis was carried out using machine learning – the variable importance method and the random forest algorithm. The obtained results allowed us to conclude that during the period of threat of the COVID-19 virus pandemic, tourist packages had been purchased less frequently, and buyers either had limited their trips to domestic trips or had adapted their travel destinations to the changing pandemic situation. The most important motivators that determined the choice of a travel agency during the COVID-19 pandemic were an attractive offer, a wide selection of package travels, previous positive experiences and trust in the organiser. It was also confirmed that in the face of the pandemic threat, buyers of package travels had been loyal to travel agencies. The use of machine learning allowed for more in-depth analyses and identification of motives that had a key impact on the development of buyer loyalty during the pandemic. The factors identified in the study encouraging buyers of package travels to maintain long-term relationships with their suppliers are belief in the value of the travel agency’s offer, trust in the travel agency, individual approach travel agency employees, efficient service in the travel agency, and a wide selection of package travels
