Plant viruses are one of the main threats to crops and food security worldwide, being very difficult to monitor and control. Since there are no effective chemical products against plant viruses, using virus-resistant plants is often the only option. Many promising strategies have been developed to engineer virus resistance however, several setbacks have hampered their utility in agriculture. In prokaryotes, clu...
Purpose – The wine sector is a growing industry with an important share of the revenue resulting from export markets. Due to its cultural nature, wine exporting requires specific firm and managerial capabilities. As such, traditional approaches to the factors influencing export performance must integrate the specificities of wine as a product. Design/methodology/approach – This study, based on a sample of 93 wi...
An individual can observe one’s surrounding space. The space can contain various elements (e.g., objects, furniture), which in turn convey visual information to the individual, giving the sense of being present within the space. The space can be filled by additional individuals who also aim to observe their surroundings. The human ability to observe and interact with the surrounding elements plays a vital role ...
In real life, the ability that people have of observing the elements of their surrounding space contributes for the sense of presence and social co-presence in that physical space. Digital avatars are often the employed means for providing a similar sense of co-presence in virtual environments. Digital avatars of the users and other co-presence amplification strategies (e.g., co-presence inducing graphical repr...
The cycling literature is filled with reports of electromyography (EMG) analyses for a better understanding of muscle function during cycling. This research is not just limited to performance, as the cyclist’s goal may be rehabilitation, recreation, or competition, so a bicycle that meets the rider’s needs is essential for a more efficient muscular activity. Therefore, the purpose of this study was to understan...
The concept of purpose gained prominence in organization theory in recent years but there are discrepant views of its meaning, which we review as evolving and different perspectives: economic theories of the firm; stakeholder approaches; integrative social contracts; and social mission. We elaborate these perspectives in terms of the ebb and flow of ideas and eras. Against these instrumental views, we revisit t...
The site of Castelinho (Torre de Moncorvo, northeast of Portugal) is a fortification strategically placed on a small elevation, near the river Sabor, built in the Late Iron Age and occupied until the Early Roman period. It is characterized by impressive defensive features, including large walls with turrets, ditches and complex en- trances, inside of which no clear evidences of domestic areas were found. On the...
Purpose: Robotic process automation (RPA) seeks to automate business processes, using software robots that interact with systems through their user interface, improving efficiency and reducing costs. However, some critical steps, such as identifying processes suitable for RPA automation, can have a tremendous impact in organizations if a wrong process is selected. Therefore, the purpose of this paper is to prov...
