The amount of PDMS in the SiO2/PDMS structure varied from 10 to 40%w. The SiO2/PDMS was impregnated into a sponge system and the amount of hydrophobic silica trapped in the sponge was evaluated by gravimetry; in addition, infrared spectroscopy will allow the identification of the hydrophobic silica in the sponge and the main functional groups of the sponge. The hydrophobic character was determined by changing the water absorption capacity of the sponge and by measuring the contact angle. On the other hand, optical microscopy allowed the identification of changes in the sponge surface due to the presence of SiO2/PDMS. Finally, the effect of the amount of PDMS on the oil-in-water removal capacity was determined.","PeriodicalId":40014,"journal":{"name":"Journal of Technology Management and Innovation","volume":"97 3 Suppl 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88704285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a real website of a rural destination as a tourism service. We tested the proposed conceptual model using structural equation modeling. Our results show a correspondence between consumers’ thoughts and the cognitive dimension of image, as well as between the emotions expressed by subjects and the affective dimension of image. Results confirm that the image of a tourism service is an important predictor of tourism service preferences. This overall image influences consumers’ future intentions, not only to buy the service but also to recommend it to other consumers. In summary, we propose and test a model that shows how online reviews significantly influence image formation and subsequent consumer behaviors. To date, little is known about to what extent online reviews are useful to generate cognitive and emotional responses in potential tourists. Consequently, understanding its role in a tourist’s decision making process, and assessing the relationships between utility of online reviews, emotions, cognitions and image towards the tourism service will make both scientific and practical contributions. While contributing to the body of knowledge on image formation process, our results are also relevant for public administrations and tourism marketing managers.","PeriodicalId":40014,"journal":{"name":"Journal of Technology Management and Innovation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48726430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A structural-functional innovation system analysis is performed, based upon 41 semi-structured interviews. The main results indicate that precision technologies are in the implementation phase in the Chilean dairy sector, with scarce experience and undeveloped knowledge of their benefits. Moreover, there are insufficient interactions between different actors with limited information sharing due to the lack of trust as a cultural issue, affecting the development of smart farming practices. Some strategies to develop and co-evolve the technological systems are discussed, as is the need to increase trust and cooperation between the actors of the dairy sector.","PeriodicalId":40014,"journal":{"name":"Journal of Technology Management and Innovation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70192599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
