Sommario/riassunto |
|
This book examines the ways in which artists and arts organizations today forge collaborative, socially engaged situations that involve non-professionals in the process of making art, often over a period of time, through creating opportunities to examine collective concerns and needs. Collaborative art praxis is gaining prominence in the Middle East, North Africa, and South Asia (MENASA) region. This is a discursive method that is experimental, with results that often expand the notions of what art is-and how it can be produced. After an introduction to global approaches to such a practice, Ali examines the foundation of contemporary art in the MENASA that is linked to a longer history of colonialism. The book analyzes artist-led initiatives and community-based organizations through themes including relational aesthetics, |

war and violence, blight in marginalized places around the world, in addition to questions associated with art and its value in the fields of global contemporaryart and society. |

Sommario/riassunto |
|
This book offers a comprehensive exploration of diatoms, a group of single-celled algae with silica shells, crucial for oxygen production and aquatic food chains. Edited by Johannes W. Goessling, João Serôdio, and Johann Lavaud, it delves into diatom biology and their applications in biofuel, solar energy, and ecological indicators. The work highlights the significant progress in diatom research, with the literature doubling every decade. It aims to provide a reliable resource for advancing knowledge on diatoms, serving researchers and students in biology and environmental sciences. The book also honors Mark Hildebrand, a notable figure in diatom molecular biology. |
