Abstract
Objetivo: descobrir a razão pela qual resultados inesperados foram gerados na determinação das publicações historicamente mais influentes (landmarks) de Ciência da Informação e Biblioteconomia (CI&B) da Web of Science (WoS). Metodologia: Recuperamos dados de todos os artigos e revisões do CI&B, do período 1980-2017 (N=93.330), identificamos e analisamos as áreas de periódicos dos artigos que citaram os landmarks. Resultados: Mostramos que os periódicos que mais citam os dois primeiros landmarks da CI&B são da área de Gestão, Negócios e Sistemas de Informação. Mostramos também que cinco dos dez primeiros landmarks possuem conteúdos fortemente voltados para Gestão, Sociologia, Marketing, Comunicação e Sistemas de Informação e que só aparecem como landmarks da CI&B porque são citados por periódicos da área de Gestão, categorizados no WoS, também, como CI&B. No caso da área “Métricas da Informação”, o resultado revela publicações reconhecidas na literatura como cruciais. Conclusões: Quando se desenvolve um estudo de uma área de pesquisa utilizando a categorização da WoS como base para a amostra, outra área pode interferir neste estudo, produzindo resultados inconsistentes. A análise da categorização dos periódicos, conforme realizada por este estudo, é fundamental para avaliar corretamente o impacto de um artigo, pois as métricas de produção utilizadas na avaliação acadêmica precisam ser normalizadas por área.

Abstract
This study aimed to identify the constructs related to customer experience that underpin e-commerce, as well as their interconnections, to develop a comprehensive conceptual model based on theories-in-use. A quantitative approach was employed through a survey of 441 respondents. Data analysis was conducted using partial least squares structural equation modeling. The research findings revealed that there are a total of 11 constructs: customer experience, customer satisfaction, customer loyalty, word-of-mouth, trust, perceived risk, security and privacy, web content, perceived price, perceived value, and service quality. Furthermore, twelve relationships were established between these constructs, which led to the development of a holistic conceptual model. The identified constructs and the relationships between them are hierarchized, which has practical implications for businesses. It allows them to concentrate on operational activities and formulate and implement strategies that are valued by consumers and supported by empirical evidence. The originality and value of this research lie in the conception and development of a comprehensive e-commerce model, which includes eleven constructs and twelve relationships. It also highlights the pivotal role of the customer experience.

Abstract
The concept of sustainable fashion is becoming more relevant in today's society. The purpose of this research is to identify the determinants of the purchase intention of sustainable fashion, and the relationship between price and the purchase of sustainable fashion. A questionnaire was administered, which made it possible to define the concept of sustainable fashion, to use PLS-SEM to identify the determinants, and to apply linear regression models and t-tests of two independent samples (two-tailed test). The concept of sustainable fashion comprises the dimensions of manufacturing with a reduced environmental impact, consuming second-hand fashion products, manufacturing in an environmentally friendly way, reusing fashion products, manufacturing to last longer, manufacturing according to fair trade principles, using recycled materials, and manufacturing from organic materials. The PLS-SEM results show that purchase intention is determined by consumer knowledge, environmental beliefs, and willingness to pay more. The research also revealed that there is a non-linear (quadratic or exponential) relationship between the price of the product and the price increase that consumers are willing to pay and that they value the dimensions of sustainable fashion differently. The purchase intention determinants of consumers and non-consumers of sustainable fashion are identical, yet the dimensions of sustainable fashion are valued differently by each group.

Abstract
Considering the beauty industry’s potential for further expansion and the mismatch between the attitudes of consumers and their buying behavior, brands should comprehend the factors that influence consumers’ intention to purchase environmentally friendly cosmetics. As such, the present study examined what encourages consumers of environmentally friendly cosmetics to choose these products. To answer the main objective of the work, the elaborated literature review aimed at identifying the factors that influence the buying of environmentally friendly cosmetics. Thus, the following were found: environmental consciousness, certification labels, brand trust, quality expectation, lifestyle, advertising, willingness to pay the price, ethical concerns and social and financial equity, physical health considerations, and knowledge of the product. The study was conducted using exploratory research with a qualitative approach. Data was collected from eight interviews, and it was identified that factors such as environmental consciousness, lifestyle, willingness to pay the price, quality expectations, ethical concerns and social and financial equity, as well as physical health considerations and knowledge of the product are the most significant determinants in the intention to buying environmentally friendly cosmetics. One of the aims of the investigation was to distinguish between the notions of green, traditional, organic, and natural cosmetics. As a result, it was found that there is a lack of clarification of the green cosmetic concept in literature, as well as a lack of standardization of criteria used by multiple systems to define different cosmetics. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Driving Green Marketing in Fashion and Retail

Abstract
In today's world, the idea of sustainable fashion is gaining traction. Finding a link between pricing and the purchase of sustainable clothes is the aim of this study. Regression models and t-tests of two independent samples (two-tailed tests) were applied by means of the application of a questionnaire. The study found that consumers' willingness to pay for price increases is related with non-linear (quadratic or exponential) product pricing. The results of this study suggest that consumers are willing to pay higher prices for sustainable clothing. Through an understanding of the relationship between price and consumer behavior, businesses can more effectively align their pricing strategies with the demands of environmentally conscious consumers. © 2024, IGI Global.

Abstract
Purpose: To evaluate the outcomes and durability of drug -eluting stents (DESs) for the treatment of hemodialysis access outflow stenosis. Material and Methods: A single -center retrospective analysis was conducted of all patients with hemodialysis vascular access outflow stenosis treated with a paclitaxel-coated DES (Eluvia; Boston Scientific, Marlborough, Massachusetts) between January 2020 and July 2022. A total of 34 DESs were implanted to treat outflow stenosis in 32 patients. Primary target lesion patency after stent deployment was the main outcome. Comparison between the time interval free from target lesion reintervention (TLR) after previous plain balloon angioplasty (PBA) and that after stent deployment for the same target lesion was considered a secondary outcome. Results: The primary patency at 6, 12, and 18 months was 63.1%, 47.6%, and 41.7%, respectively. The secondary patency rate was 100% at 18 months. The median time interval free from TLR increased from 4.1 to 11.9 months (P < .001). No adverse events were observed during the median follow-up period of 387 days. Conclusions: The patency rates after use of DES for hemodialysis access outflow stenosis were comparable with results for drug -coated balloons and stent grafts, addressing recoil and minimizing the risk of jailing by a covered stent.
