Do consumers intend to buy more co-created green products than traditionally developed green products?

The globe is currently facing a number of environmental issues that require the rapid development of ecological technologies. Green product purchases continue to fall short of market forecasts. One of the causes of this behavior is a lack of trust in corporate environmental claims. According to the literature, co-creation is a strategy for increasing consumers' trust and, as a result, their buying intentions. Additionally, firms that foster co-creation are perceived as being more customer-centric, which should lead to more favorable attitudes toward consumption. According to two studies conducted on this research, co-creation of green products increases consumer trust. Literature also states that the relevance of political orientation as a moderator between the type of development (co-creation vs professionals only) and consumer trust is considered significant. Liberal consumers (with low-power distance) tend to trust more in co-created products, whereas conservative consumers (with a high-power distance) are more likely to trust products generated solely by experts. Despite the above, the effects of co-creation on the green economy have yet to receive much attention. Therefore, the main goal of this dissertation is to help executives better understand how co-creation can contribute to increasing consumer trust. Hence, companies should more commonly use co-creation in the development of green products in order to generate trust and additional sales. There are also limitations and suggestions for future research.O mundo está atualmente a enfrentar uma série de questões ambientais que exigem o rápido desenvolvimento de tecnologias ecológicas. As compras de produtos verdes continuam aquém das previsões do mercado. Uma das causas deste comportamento é a falta de confiança nas declarações ambientais corporativas. De acordo com a literatura, a cocriação é uma estratégia para aumentar a confiança dos consumidores e, consequentemente, as suas intenções de compra. Além disso, as empresas que promovem a cocriação são percebidas como mais centradas no cliente, o que deve levar a atitudes mais favoráveis em relação ao consumo. De acordo com dois estudos realizados nesta pesquisa, a cocriação de produtos verdes aumenta a confiança do consumidor. A literatura também afirma que a relevância da orientação política como moderador entre o tipo de desenvolvimento (cocriação vs. apenas profissionais) e a confiança do consumidor é considerada significativa. Consumidores liberais (com distância de baixa potência) tendem a confiar mais em produtos cocriados, enquanto consumidores conservadores (com distância de alta potência) são mais propensos a confiar em produtos gerados exclusivamente por especialistas. Apesar do exposto, os efeitos da cocriação na economia verde ainda precisam receber muita atenção. Portanto, o principal objetivo desta dissertação é ajudar os executivos a entender melhor como a cocriação pode contribuir para aumentar a confiança do consumidor. Assim, as empresas devem usar mais frequentemente a cocriação no desenvolvimento de produtos verdes para gerar confiança e vendas adicionais. Há também limitações e sugestões para pesquisas futuras

MEDIÇÃO DE PROCESSOS DE COLISÃO ELETRÓNICA EM FE XVII DE INTERESSE ASTROFÍSICO

UID/FIS/04559/2020A análise de espectros de raios-X de alta resolução obtidos em observatórios espaciais requer uma boa compreensão dos processos físicos, nomeadamente os atómicos, que governam a emissão e dinâmica dos plasmas. O complexo de emissão Fe-L de Fe XVII, formado por riscas 3d→2p e 3s→2p, é frequentemente utilizado na referida análise e como diagnóstico de várias propriedades físicas como temperatura, opacidade e densidade do plasma. Neste trabalho, medimos as secções eficazes dos processos de colisão que levam à formação destas riscas, tanto as não-ressoantes (excitação por colisão), como ressoantes (recombinação dieletrónica). Acresce que os dados experimentais obtidos permitem uma validação dos valores teóricos destes processos atómicos.authorsversionpublishe

Evaluation of Microleakage of a New Bioactive Material for Restoration of Posterior Teeth: An In Vitro Radioactive Model

Hybrid bioactive composite resins combine the benefits of glass ionomer cements with composite resins. Its self-adhesiveness is achieved through functional polyacrylic acids and carboxylic groups, hybridizing the smear layer and establishing ionic interactions between calcium and dentin. These materials are defined as having good aesthetics, moisture tolerance, durability, simplicity in technique and handling and are able to maintain a low microfiltration rate while releasing calcium, phosphate and fluorine. The aim of the present study was to evaluate microleakage in restorations using Surefill One™ bioactive resin. The null hypothesis is that this type of resin does not obtain a lower microleakage rate when compared to other materials. An in vitro study was carried out using thirty-six premolars and molars extracted for orthodontic reasons. Identical preparations were thus performed in all of them (Class V with 4 mm mesio-distal, 3 mm occluso-gingival and 3 mm in depth) and divided into different experimental groups: one positive control, one negative control and two tests with bioactive composite resin and conventional composite resin (Surefill One™ and Spectra™ ST HV, respectively). Through quantitative techniques using nuclear medicine, it was possible to evaluate microleakage through the use of a radioactive isotope, technetium. Radioactivity emitted by the specimens was detected by a gamma camera. The different groups were compared using the Kruskal–Wallis test and the Games–Howell test for multiple comparisons. The results of the experimental study point to statistically significant differences between the test groups (p = 0.002) with increased microleakage in the bioactive composite resin group. Based on the present microleakage study, it was possible to conclude that the bioactive composite resin (Surefill One™) does not reduce the microleakage rate when compared to a conventional nanohybrid composite resin (Spectra™ ST HV). However, Surefill One™ can be used in temporary restorations, primary teeth and in cases of tissue remineralization, thus avoiding more invasive procedures
