How does digital transformation affect innovation quality?
(2024-10-04) Pu, Tingqian; Zulkafli, Abdul Hadi
In the digital era, digital transformation is disrupting traditional business models and innovation activities. Numerous firms have expedited their endeavors in digital transformation to augment their manufacturing capabilities, operational efficiency, and competitive standing. Despite the increasing scholarly attention on the pivotal role of digital transformation in economic progress, there exists a paucity of research delving into the intricate nexus between digital transformation and innovation quality. The objective of this study is to investigate the relationship between digital transformation and innovation quality. Leveraging annual report data and patent information from Chinese listed companies spanning from 2012 to 2021, we have identified that digital transformation significantly enhances innovation quality. Interestingly, upon further investigation into the relationship between the five sub-dimensions of digital transformation (artificial intelligence, blockchain, cloud computing, big data, and digital technology applications) and innovation quality, positive and significant correlations were observed with artificial intelligence, cloud computing, big data, and digital technology applications, while blockchain did not exhibit a significant impact. Furthermore, the study reveals that the impact of digital transformation on innovation quality varies depending on property rights and regional location. Specifically, this promotional effect is significant only in non-state-owned enterprises and in the central and eastern regions. Overall, this paper enriches the research on digital transformation and innovation quality, providing valuable insights to promote the advancement of digital transformation levels for better serving the high-quality development of the real economy.

How and why does inner resignation (quiet quitting) impact service innovation behavior? A moderator role of ethical leadership
(2024-10-04) Ustun, Ferda; Koca Balli, Ayse Ipek; Balli, Erdinc
Tourism enterprises are labor-intensive, and the service innovation behavior of employees plays an important role in keeping these enterprises ahead of their competitors. Inner resignation (IR) is a relatively new concept in organizational life, and it is a situation that should be prevented due to its negative impact on the organization. In this study, the moderating role of ethical leadership (EL) in reducing the negative effect of inner resignation on service innovation behavior (SIB) was examined with a cross-cultural comparison for Turkish and German tourism employees. A total of 743 employees working in hotels in Turkey and Germany were surveyed using a questionnaire. The results of the research show that employees’ inner resignation has a negative impact on their service innovation behavior. On the other hand, ethical leadership plays a moderating role in the effect of inner resignation on service innovating behavior. The moderator role of ethical leadership perceptions in this relationship was also examined separately for German and Turkish employees due to cultural differences. While the moderating role of ethical leadership in the effect of German employees’ inner resignation on service innovating behavior was found to be statistically significant, this role was found to be insignificant for Turkish employees.

IMAGE-BASED CROSS-SECTIONAL ANALYSIS AND MICROMECHANICAL MODELING OF YARN AND COMPOSITE MATERIALS
(Technical University of Liberec, ) Overberg, Matthias; Zalewska, Emilia; Abdkader, Anwar; Cherif, Chokri; Technická univerzita v Liberci
This study aims to establish a comprehensive methodology for determining the microstructural properties of hybrid yarns used in composite materials. By developing accurate models of hybrid yarns and composites based on detailed microstructural information such as fibre orientation, fibre diameter and distribution, this approach lays the foundation for future advances. These models, enriched with accurate microstructural data, will facilitate the creation of new modelling techniques that can be used in future research to explore the correlation between microstructural properties and mechanical performance of composite materials.

SPECTROKINETIC INVESTIGATION OF THE PHOTOCHROMIC SYSTEM UNDER CONTINUOUS UV IRRADIANCE USING REFLECTANCE VS. TIME CURVES
(Technical University of Liberec, ) Solanki, Utkarshsinh B.; Viková, Martina; Vik, Michal; Technická univerzita v Liberci
The photochromic properties of the dye 5-chloro-1,3,3-trimethylspiro[indoline-2,3'-[3H] naphtho[2,1-b] [1,4]- oxazine] were investigated by exposing it to continuous monochromatic irradiation using 360 nm ultraviolet irradiation using photochromic prints at 293.15  2 K; it undergoes a photocoloration and photodecoloration state, thus following the dynamics of a photochromic cycle of growth and decay phase, respectively. Even if the isolated photo isomeric form of the photochromic dye structure is unavailable, one can quantitatively analyse the photo-induced kinetics of photochromic systems using the raw reflectance data. The quantum colour yield is represented by colour span values [K/S] obtained by converting reflectance data to Kubelka- Munk values. The dynamics of the photoreaction in a photochromic system can be examined by analysing the constants for the rate of colouration and decolouration caused by light. By employing first-order kinetics, the dependent dominant wavelength [max] can be determined by fitting the raw data obtained as a change in reflectance values from the FOTOCHROM3 spectrophotometer. The relationship between the colour span values and the concentration of the photochromic dye employed in the photochromic prints is linear.

ANTIVIRAL TEXTILES AND ANTIVIRAL ACTIVITY TESTING - THE USE OF BACTERIOPHAGE SURROGATE FOR ANTIVIRAL ACTIVITY TESTING
(Technical University of Liberec, ) Tvrzová, Ludmila; Bláhová, Anna; Fojt, Jakub; Doubková, Hana; Procházka, Jiří; Technická univerzita v Liberci
The risk of dissemination of highly contagious viral diseases (as COVID-19, Ebola) led in the increasing need to develop functional textiles and surfaces with antiviral effect. Antiviral textiles are designed to reduce the viability and infectivity of viruses on their surfaces and by this way to reduce the cases of infection (including re-infection or cross-infection with contaminated textiles). Different antiviral agents and diverse techniques of their application are used for functionalized textiles manufacturing. The most often used antivirals are metallic and ionic silver and copper, iron oxide, quaternary ammonium salts. The aim of the process is to prepare textiles with long-term durable finishing effective in viral activity inhibition. The basic step of functionalized antiviral textiles development is antiviral effectivity testing. The safe method of testing with the use of Phi6 bacteriophage, SARS-CoV-2 and Ebola virus surrogate, was modified for antiviral textiles testing. The samples of textiles with antiviral finishing were tested by the bacteriophage-based method and excellent antiviral activity was detected for all tested materials. The woven cotton was used as reference untreated material, the different textile cotton structures with similar square weight were compared and no statistically significant difference was found between the resulting antiviral efficacy values. A simple and quickly feasible screening method for determining the antiviral properties of textiles, especially with leaching-type of treatment, was also designed and tested.
