There is an immediate need to identify alternative sources of high-nutrient feedstocks for domestic livestock production and poultry, not only to support growing food demands but also to produce microalgae-source functional foods with multiple health benefits. Various species of microalgae and cyanobacteria are used to supplement existing feedstocks. In this review, microalgae have been defined as a potential feedstock for domestic animals due to their abundance of proteins, carbohydrates, lipids, minerals, vitamins, and other high-value products. Additionally, the positive physiological effects on products of animals fed with microalgal biomass have been compiled and recommendations are listed to enhance the assimilation of biomolecules in ruminant and nonruminant animals, which possess differing digestive systems. Furthermore, the role of microalgae as prebiotics is also discussed. With regards to large scale cultivation of microalgae for use as feed, many economic trade-offs must be considered such as the selection of strains with desired nutritional properties, cultivation systems, and steps for downstream processing. These factors are highlighted with further investigations needed to reduce the overall costs of cultivation. Finally, this review outlines the pros and cons of utilizing microalgae as a supplementary feedstock for poultry and cattle, existing cultivation strategies, and the economics of large-scale microalgal production.

The experience of a lack of time due to an increasing burden of urgent tasks is one of the more common challenges created by digital communication media in the network society. This study develops the concept of chronemic urgency to explore urgent messaging using digital media. Chronemic urgency is the urgency users assign to messages received via a specific communication medium. Consistent with a communication perspective, the urgency is a function of both the relationship and the media. This study uses social entrainment theory and expectancy violations theory to conceptualize the chronemic urgency construct. This construct is then examined in a pilot study of the chronemic urgency 773 US-based participants assign to the communication media they use at least on a weekly basis. High chronemic urgency is assigned to messages received through media that (1) are used for urgent communication, (2) are checked more often, (3) are likely to be used by others who wish to contact the user urgently, and (4) are likely to lead to a quicker response. Despite the increasing centrality of urgency in everyday communication in the digital age, researchers and practitioners lack reliable methods to measure chronemic urgency in populations. The findings provide initial indications of levels of chronemic urgency in the US population’s everyday digital communication and create a foundation to better understand contemporary temporal phenomena.

Hundreds of messages and conversations stream daily into our communication media and devices. How do we manage this influx without missing urgent messages? In this study we provide initial evidence that this is achieved by closely monitoring only a small number of media-those media where users expect time sensitive messages to arrive. We describe this heightened attention to a medium as "assigning the medium high chronemic agency", and characterize chronemic agency through extensive interviews of eighteen American undergraduate students. Our findings reveal how chronemic agency is involved in communication norms associated with urgency. Furthermore, they demonstrate the dynamic nature of chronemic agency, and its role in managing responsiveness and in dealing with communication overload. We conclude with a discussion of the shifting nature of the synchronicity of mediated conversation.
