In times of pandemic - How generation XYZ looks digital banking

In a time of digital disruption, users are deciding how they want banks to respond and exceed their expectations. The banking industry since pandemic has shifted servicing dramatically from its traditional branches to become far more digitally flexible. Banks rushed to face-lift the front-end look and feel and enable non-essential digital services without asking users their needs. Thus, this bank attitude as greater impact on building a good digital banking customer experience that leads the users to fully adopt digital. To have a clear vision of how banks can stand out to a successful digital transformation we interview 634 digital bank users from the generation XYZ. To find out about the digital banking perceptions of Generation Z (born 1997-2012), Generation Y (born 1981-1996), and Generation X (born 1965-1980) we perform a qualitative analysis using Leximancer content analysis software to determine differences and characteristics of users’ attitudes toward digital banking. The findings highlighted nineteen concepts (transfers, bank, channels, products, digital, availability, anywhere, services, operations, use, account, savings, speed, costs, information, options, price, complex, and market) grouped in eight key themes perceived by users using digital banking channels, namely: transfers, availability, use, speed, information, price, complex and market. The three tags categories generation XYZ result of the presence of highly connected with concepts or independent variables showing prominence between X-generation and availability and services concept, Y-generation, and market, anywhere, bank and operation concepts, Z-generation, and transfers concepts. These results show that digital bank users are concerned about price, speed of transfers and product information, the anywhere availability of services and operations in the financial market, with some constraints about the complexity of options used to manage their accounts and savings. More the Y-generation (middle age) take more advantage of digital banking to explore bank/financial market and perform operations anywhere, the X-generation (older age) look digital banking mainly for the availability of services and Z-generation (younger age) simple for transfers. This study contributes to understanding the use and preference of digital banking, allowing us to propose a new conceptual model to explain the digital banking usage, helps to identify what is important for each XYZ generation to increase their adoption of digital banking and alerts to the use complex of multiple options that probably are not the focus to successfully used by this generations. Highlighting the users’ perceptions is important for the bank industry to develop digital banking features that align with users’ expectations and to increase the success of digital transformation by shifting servicing dramatically from a brick-and-mortar stalwart to become far more business digitally flexible.info:eu-repo/semantics/publishedVersio

Main gamification concepts: a systematic mapping study

Gamification involves incorporating elements of online games, such as points, leaderboards, and badges into nongame contexts, in order to improve engagement with both employees and consumers. The main point of this paper is, to sum up, what previous authors investigated in the field of Gamification. An analysis of the literature covering 50 papers from 2011 to 2016 was conducted, using Leximancer software, to determine and shape the main themes and concepts proposed in gamification papers. Answering our research question, “What guidelines may provide to future research, the key themes and concepts found in published scientific papers on gamification?”, we conclude that the researchers identified eight themes (gamification; game; use; users; business; points; engagement; learning) and twenty-eight related concepts. The present systematic review contributes to establishing possible guidelines for prospective studies, based on the analyzed papers, considering particularly their 'Conclusions' and on the 'Future research' sections, integrating game design contents in business, learning and education. Further, highlights the usefulness of Leximancer for qualitative content analysis, in this field of research.info:eu-repo/semantics/publishedVersio

Technology management has a significant impact on digital transformation in the banking sector

Technology management and a good relationship among employees are vital keys to assure any digital transformation process. We may therefore rightly ask “What are the main drivers influencing IT and non-IT employee relationships that may have an impact on digital transformation in the banking sector?“. Aiming to identify those drivers, we developed a questionnaire for an exploratory study into employees' perceptions of the IT or non-IT measures undertaken to improve any digital transformation project. We had a sample of 604 bank employees working in software development. Leximancer was used as a qualitative technique tool for content textual analyses. The findings highlighted seven key factors that have an impact on digital transformation, namely: department, lack of cooperation, communication, requests, experience, relationship, and business. Internal clients tend to have a negative perception of IT developers mainly due to a lack of understanding of business requests. This study contributes to scholarship with a conceptual model to explain the main concepts that may affect the relationship between IT and non-IT employees’ and departments teamwork in the digital transformation process, in the banking sector specifically. We also contribute by identifying the most important elements to achieve organizational success.info:eu-repo/semantics/publishedVersio

Tuned liquid dampers simulation for earthquake response control of buildings

This paper is focused on the study of an earthquake protection system, the Tuned Liquid Damper (TLD), which can, if adequately designed, reduce earthquake demands on buildings. This positive effect is accomplished taking into account the oscillation of the free surface of a fluid inside a tank (sloshing). The behaviour of an isolated Tuned Liquid Damper, subjected to a sinusoidal excitation at its base, with different displacement amplitudes, was studied by finite element analysis. The efficiency of the TLD in improving the seismic response of an existing building, representative of modern architecture buildings in southern European countries was also evaluated based on linear dynamic analyses
