To the top: the impact of digital transformation on the market value of Magazine Luiza

Objective of the study: This article aims to highlight the aspects that drove the implementation of digital transformation on Magazine Luiza and contribute to the development of the digital transformation theory.Relevance/originality: Information technology (IT) offers opportunities for businesses to automatize operations and change business strategies (Henderson Venkatraman, 1999), but it is still not clear for every business how to embrace technology (Drnevich Croson, 2013).Methodology/approach: Using a case study, we analyzed the main aspects of the digital transformation of the Brazilian retailer Luiza Magazine, which achieved a 43,000% increase in its share price between 2015 and 2020, mainly due to innovations enabled by IT.Main results: We identify that some of the main aspects of the company's digital transformation have not been properly studied in the literature, such as the use of a bimodal IT structure and the use and interconnectivity between traditional and new technologies in innovative and even disruptive ways.Theoretical/methodological contributions: This study contributes to the literature by analyzing empirical data on the pillars that support the implementation of digital transformation in an organization, which can be used as input to theory development on digital transformation.Social/management contributions: The digital transformation of Magazine Luiza resulted in a large increase in the market value of the company. This, aligned with the company’s expansion and increasingly better results, suggests that technology has the potential to change the company’s strategy and lead to its success, corroborating Bharadwaj’s (2013) view.

The Structures and Functions of Lexical Bundles in Argumentative Essays by Chinese EFL Students at the Tertiary Level

The present study investigated and analysed the structures and functions of 3-word to 6-word lexical bundles of 120 English argumentative writing by Chinese EFL students and employed the framework based on Biber et al.’s structural classification and Hyland’s functional classification of lexical bundles. It was found that there was generally a negative correlation, both structurally and functionally, between the frequency and the length of lexical bundles although there were some fluctuations in certain specific categories. Results indicated that the participants did not have a good command of lexical bundles, affecting the quality of English argumentative writing in various ways. First, the sampled students used limited types of lexical bundles frequently. They generally lacked lexical richness when employing specific lexical bundles to express their opinions and text-oriented lexical bundles to convey transitional signals. Second, they relied heavily on the anticipatory it structure and did not have the consciousness of using hedges and boosters when expressing their attitude. Third, they virtually did not use lexical bundles involving attributive clauses. Fourth, they are inclined to use colloquial language in writing. The paper includes implications for instruction of effective use of lexical bundles in argumentative writing.

Impact response of different materials for sports mouthguards

Up to this moment, there is no guideline regarding the materials to produce mouthguards. The most used is Ethylene-Vinyl Acetate (EVA). Studies indicate that laminating EVA sheets with rigid components could increase the protection capacities of the mouthguards whereas other studies suggest that only replacement of the material within it structure can increase energy absorption. The aim of this work is to evaluate the impact response of four different foils when compared to a 4 mm thickness EVA sheet. Five groups of different materials were subjected to impact tests with energies of 1.72 J, 2.85 J and 4.40 J. In this context was considered the following materials: EVA foils (G1), EVA foils with an EVA foam core (G2), EVA foils with an acetate core (G3), Foils of Erkoloc-pro (G4) and Foils of Ortho IBT resin (G5). Comparisons between the materials were made by qualitative analysis of the average energy-time and load-displacement curves, as well as by comparison of the peak load, maximum displacement, contact time and absorbed energy using the Kruskal-Wallis test. It was possible to conclude that statistically significant differences were found in the energy absorbed (p=0.001). Laminated foils with a soft core (G2) are a good option to produce mouthguards, while EVA foils with an acetate core (G3) and foils of Ortho IBT resin (G5) were declared unsuitable.

METODE PMBENTUKAN AKHLAK PERSPEKTIF M. QURAISH SHIHAB

Ibn Abbas, one of the companions of the Prophet classified the level of rasikh in understanding al Qur’an verses as four parts: first, it is able to be understood by Arabian generally based on their linguistic; second, there is no reason for them to let it; third, noone knows except scholars; and fourth, only Allah knows it. This is proof of the miracles and the truth of the prophet Muhammad SAW, one of the al Qur’an terms of language which can be accepted by the owner’s only. Besides, Muhammad’s friends who witnessed the al Qur’an descent, they knew and understood it structure and vocabulary of the language, and the context of the verses passage, so the appreciation of the al Qur’an interpretation is always needed by the Indonesian mufassir that is M. Quraish Shihab in tafsir al Misbah.

Interaction of lysine dendrimer with 8 and 16 molecules of EDR peptide

Dendrimers are frequently used for drug molecules delivery to different cells or organs. In our previous papers we used computer simulation to study the complex formation between dendrimers and dendrigrafts with different short regulatory peptides. The goal of present paper is to study interaction and the possibility of complex formation between lysine dendrimer and molecules of therapeutic EDR peptide. The system consisting of one lysine dendrimer of the second generation and 8 or 16 therapeutic EDR peptide molecules in water with explicit counterions was studied by computer simulation. The method of molecular dynamics and full atomic model were used for this goal. It was obtained that EDR peptide molecules become adsorbed by lysine dendrimer and form stable complex with it. Structure and conformational properties of this complex were studied. It was demonstrated that formation of complex occurs mainly due to electrostatic interaction between oppositely charged dendrimer and peptide molecules. Such complexes could be used in future for delivery of these or similar peptide molecules to the targeted tissues and organs.
