Par Gabriela Debrunner. 2024
Affordable housing shortage and social exclusion have become severe societal problems across the globe. Increasing numbers of people are suffering…
from social eviction and displacement due to urban densification, modernization, rising rents, and intense housing commodification. Vulnerable resident groups – such as old-aged or households with children – who often live in old housing stocks planned to be densified, renovated, or upgraded with higher rents, are forced to leave the urban core centers because they can no longer afford to live in central locations, or because they experience unstable or insecure housing conditions. A scenario that is highly unsustainable.So far, studies on densification have mainly considered the process as technological, architectural, or design-based problem (e.g., Kyttä et al., 2013; Broitman & Koomen, 2015; Bibby et al., 2018). However, systematic knowledge on how to implement densification objectives sustainably – regarding economic, environmental, and social aspects – is still lacking. This book tackles this gap by analyzing densification from a governance perspective. Its point of departure is that densification per se does not necessarily lead to sustainable outcomes in terms of social inclusion, cohesion, or community stability. Rather, it politicizes densification by neglecting how the process is planned, implemented, and governed by the actors involved.The book applies an actors-centered neoinstitutionalist political ecology approach to reveal the specific objectives and strategies of actors involved, as well as the socio-political structures (i.e. rules. laws, and policies) that govern densification. Four Swiss in-depth empirical qualitative case studies (Zürich, Basel, Köniz, and Kloten) illustrate the political and legal conditions for success or failure for (un)sustainable implementations of densification. Ultimately, this book advises stakeholders, governments, urban practitioners, and academics on more effective, community-oriented, collective, and decommodified forms of governance to respond to the needs of the public at large rather than simply catering to private individuals and firms. Such governance initiatives entail active municipal land policy approaches outside a purely market-based investment logic that not only limit, but also work with property rights.This is an open access book.Brain-Computer Interface Research: A State-of-the-Art Summary 11 (SpringerBriefs in Electrical and Computer Engineering)

Par Grant Duncan. 2024
If the government is a problem, what should be done about it? A new era of intervention has begun following…
a global pandemic, climate change and strategic rivalry – but will a better government emerge from this? Political turmoil and polarisation are causing people to question how well their societies are governed and how leaders conduct themselves, while urgent practical challenges are arising for public policy and administration. A deeper concern, then, is to re-examine the nature and problem of government itself. This study covers historically enduring dilemmas that will persist, as well as emerging issues such as climate change and Artificial Intelligence. It sets out core concerns that systems of government, of all kinds, must address. The wide diversity of political beliefs and constitutions calls for toleration in order to foster effective collaboration across types and levels of government. Each country, community and individual follows their own path, but we can all do something to help restore political trust and to raise standards of public administration. An essential guide for those seeking general and lasting principles of good government, including elected officials, civil servants, community leaders and students of politics and public policy.Ecological Sustainability of Fish Resources of Inland Waters of the Western Balkans: Freshwater Fish Stocks, Sustainable Use and Conservation (Fish & Fisheries Series #43)

This book provides a detailed evaluation of the hydro-ecological characteristics of the Western Balkans, an area characterized by still preserved…
inland waters and fish resources important for the European continent, as well as the biodiversity of inland waters important for the planet Earth. Freshwater ecosystems cover only 1% of the Earth's surface; however, they are a habitat for about 40% of fish species. At the same time, inland fisheries make less than 12% of the world's global fish catch, with 43% coming from low-income and food-deficient countries (Africa, South America, Southeast Asia). In Europe, the Western Balkans have significant fishing waters and fish resources, including the Middle Danube drainage (Sava, Drina, Velika Morava river systems), large ancient lakes (Skadar/Shkodra, Ohrid, Prespa, Dojran), and the Adriatic basin characterized by endemic and commercially important species. However, in contrast to the high fishing potential in a significant part of the Western Balkans, diverse and specific political, economic, and social factors largely had a negative impact on the state of fish resources. This volume is multidisciplinary and provides a sound knowledge base for scientific and practical fisheries. In addition, it may be a valuable guide for managers and conservationists worldwide to adapt methods and procedures for the ecological sustainability of fish resources under specific local, natural, and socio-economic conditions. Finally, the content is a good reference for natural sciences and agriculture students studying fish, fish resources, and fisheries sciences. It would improve their knowledge and perspectives on the challenges of sustainable use and conservation of inland water resources.Polystomatid Flatworms: State of Knowledge and Future Trends (Zoological Monographs #9)

Par Paul Davies. 2007
An acclaimed physicist and cosmologist considers the multiverse and more: &“Very readable indeed . . . This is Doctor Who, but for real.&” —TheGuardianThe…
Goldilocks Enigma is Paul Davies&’s eagerly awaited return to cosmology, the successor to his critically acclaimed bestseller The Mind of God. Here he tackles all the &“big questions,&” including the biggest of them all: Why does the universe seem so well adapted for life? In his characteristically clear and elegant style, Davies shows how recent scientific discoveries point to a perplexing fact: many different aspects of the cosmos, from the properties of the humble carbon atom to the speed of light, seem tailor-made to produce life. A radical new theory says it&’s because our universe is just one of an infinite number of universes, each one slightly different. Our universe is bio-friendly by accident—we just happened to win the cosmic jackpot. While this &“multiverse&” theory is compelling, it has bizarre implications, such as the existence of infinite copies of each of us and Matrix-like simulated universes. And it still leaves a lot unexplained. Davies believes there&’s a more satisfying solution to the problem of existence: the observations we make today could help shape the nature of reality in the remote past. If this is true, then life—and, ultimately, consciousness—aren&’t just incidental byproducts of nature, but central players in the evolution of the universe. Whether he&’s elucidating dark matter or dark energy, M-theory or the multiverse, Davies brings the leading edge of science into sharp focus, provoking us to think about the cosmos and our place within it in new and thrilling ways.Digital Transformation: What are the Smart Cities Today?
