Book Description
Offers a frontline take on 25 years of environmental successes and the massive challenges facing this planet and its people. From permaculture's origins in Australia in the 1970s to its current activities in over 170 countries worldwide, Harland explores the positive developments of this global movement and the potential it has yet to achieve. Her narrative is contextualized by significant trends and events: wars, disasters, deforestation, rising sea levels, the threat to the Gulf Stream, 9/11, Occupy, the rise of Trump, Brexit and climate denial. From discussions of practical permaculture to ruminations on deep ecology and global transformation, Harland contrasts the permaculture perspective with the ecocide of business as usual. Her writings reference concepts such as regenerative culture, earth restoration and social permaculture, long before they were to become core permaculture ideas and practices. These editorials from the mid 1990s to today, comprise a portrait of an increasingly global movement, represent a forthright and compassionate call to arms, and offer pathways to hope and strength in times of crisis. --From publisher description.

Book Description
In this book, methods from fractal geometry are applied to model growth forms, taking as a case study a type of growth process which can be found among various taxonomic classes such as sponges and corals. These models can be used, for example, to understand the amazing variety of forms to be found in a coral reef and to simulate their growth with 2D and 3D geometrical objects. Models which mimic the growth of forms and the environmental influence on the growth process are also useful for ecologists, as a combination of simulation models together with the actual growth forms can be used to detect the effects of slow changes in the environment.

Book Description
In this thesis we describe dualities in directed as well as undirected graphs based on tools such as width-parameters, obstructions and substructures. We mainly focus on directed graphs and their structure. In the context of a long open conjecture that bounds the monotonicity costs of a version of the directed cops and robber game, we introduce new width-measures based on directed separations that are closely related to DAG-width. We identify a tangle-like obstruction for which we prove a duality theorem. Johnson, Reed, Robertson, Seymour and Thomas introduced the width measure directed treewidth as a generalisation of treewidth for directed graphs. We introduce a new width measure, the cyclewidth, which is parametrically equivalent to directed treewidth. Making use of the connection between directed graphs and bipartite graphs with perfect matchings we characterise the digraphs of low cyclewidth. Generalising the seminal work by Robertson and Seymour resulting in a global structure theorem for undirected graphs, there is the goal of obtaining a structure theorem, based on directed treewidth, describing the structure of the directed graphs excluding a fixed butterfly minor. Working in this direction we present a new flat wall theorem for directed graphs which we believe to provide a better base for a directed structure theorem than the existing ones. On undirected graphs we present several results on induced subgraphs in the graphs themselves or the square graph of their linegraph. These results range from general statements about all graphs to the consideration of specific graph classes such as the one with exactly two moplexes. In der vorliegenden Arbeit beschreiben wir Dualitäten in gerichteten sowie in ungerichteten Graphen basierend auf Konzepten wie Weiteparametern, Obstruktionen und Substrukturen. Der Hauptfokus der Arbeit liegt bei gerichteten Graphen und ihrer Struktur. Im Kontext einer lange offenen Vermutung, dass die Monotoniekosten einer Variante des Räuber und Gendarm Spiels für gerichtete Graphen beschränkt sind, führen wir neue Weiteparameter ein, die auf gerichteten Separationen basieren und eng mit DAG-Weite verwandt sind. Wir identifizieren Tangle-artige Obstruktionen zu diesen Weiteparametern und beweisen die Dualität zwischen diesen beiden Konzepten. Johnson, Reed, Robertson, Seymour und Thomas haben die gerichtete Baumweite als gerichtete Verallgemeinerung der Baumweite auf ungerichteten Graphen eingeführt. Wir führen einen neuen Weiteparameter, die Cyclewidth, ein, der parametrisch equivalent zur gerichteten Baumweite ist. Unter Nutzung der Verwandtschaft von gerichteten Graphen und bipartiten Graphen mit perfekten Matchings charakterisieren wir die gerichteten Graphen mit kleiner Cyclewidth. Ein einschlagendes Ergebnis in der Graphenstrukturtheorie ist das Strukturtheorem von Robertson und Seymour. Basierend darauf gibt es Anstrengungen ein solches Strukturtheorem auch für gerichtete Graphen zu finden und dafür die gerichtete Baumweite als Grundlage zu nutzen. Dieses Theorem soll die Struktur aller gerichteten Graphen beschreiben, die einen festen gerichteten Graphen als Butterflyminoren ausschließen. In diesem Kontext beweisen wir ein neues Flat-wall-theorem für gerichtete Graphen, dass unserer Erwartung nach eine bessere Basis für ein gerichtetes Strukturtheorem bietet als die bisher betrachteten Alternativen. Auf ungerichteten Graphen präsentieren wir einige Ergebnisse bezüglich induzierten Subgraphen in gegebenen Graphen oder ihren Linegraphen. Diese Ergebnisse reichen von der Betrachtung spezifischer Graphklassen, wie den Graphen mit zwei Moplexen, bis zu Ergebnissen auf der allgemeinen Klasse aller Graphen.

Book Description
Education as if people and planet mattered In Transformative Learning, Satish Kumar reflects on the legacy of Schumacher College, a beacon of innovation that fosters an ecological-based, holistic model of higher education built around the college's unique "learn by doing," head, heart, and hands pedagogy. Over fifty current and former instructors and alumni, including Vandana Shiva, David Orr, Kate Raworth, Fritjof Capra, Bill McKibben, Mary Evelyn Tucker, and Jonathon Porritt, paint a rich picture of education for human well-being and the ecological health of the planet. Contributions delve deeply into the nature of transformational learning and holistic education, present a wealth of alumni experiences of working towards an ecological society, and detail the expansion of the Schumacher model to Belgium, Brazil, India, Japan, and beyond. The result is a rich tapestry of ideas and educational methods packed with insights and experience for practitioners and activists looking to build a just, ecological society.

Book Description
“Big ideas that just might save the world”—The Guardian The founder of the international Transition Towns movement asks why true creative, positive thinking is in decline, asserts that it's more important now than ever, and suggests ways our communities can revive and reclaim it. In these times of deep division and deeper despair, if there is a consensus about anything in the world, it is that the future is going to be awful. There is an epidemic of loneliness, an epidemic of anxiety, a mental health crisis of vast proportions, especially among young people. There’s a rise in extremist movements and governments. Catastrophic climate change. Biodiversity loss. Food insecurity. The fracturing of ecosystems and communities beyond, it seems, repair. The future—to say nothing of the present—looks grim. But as Transition movement cofounder Rob Hopkins tells us, there is plenty of evidence that things can change, and cultures can change, rapidly, dramatically, and unexpectedly—for the better. He has seen it happen around the world and in his own town of Totnes, England, where the community is becoming its own housing developer, energy company, enterprise incubator, and local food network—with cascading benefits to the community that extend far beyond the projects themselves. We do have the capability to effect dramatic change, Hopkins argues, but we’re failing because we’ve largely allowed our most critical tool to languish: human imagination. As defined by social reformer John Dewey, imagination is the ability to look at things as if they could be otherwise. The ability, that is, to ask What if? And if there was ever a time when we needed that ability, it is now. Imagination is central to empathy, to creating better lives, to envisioning and then enacting a positive future. Yet imagination is also demonstrably in decline at precisely the moment when we need it most. In this passionate exploration, Hopkins asks why imagination is in decline, and what we must do to revive and reclaim it. Once we do, there is no end to what we might accomplish. From What Is to What If is a call to action to reclaim and unleash our collective imagination, told through the stories of individuals and communities around the world who are doing it now, as we speak, and witnessing often rapid and dramatic change for the better.

Book Description
This unique volume of writings by educators in the field working with women's literacy reveals the many ways in which addressing women's empowerment through literacy continues to impact lives. Not only are teachers and learners in adult basic education (ABE), literacy and English language learning (ELL) classes affected, but also those who value and support women’s learning and equity, and education for social change. Revelations-- More than half of the 3.6 million students in adult basic/literacy education (ABE) programs across the U.S. are women (Sticht, 2001). Research outlines many barriers for women pursuing basic education and literacy, and recommends using woman-positive approaches (Sheared, 1994). However, there exists little research on how educational systems and policies, instructional materials, and pedagogical practices best support the literacy and educational achievement of women literacy learners. Writings and curriculum by individual educators outline and describe innovative activities/ programs focused specifically on the needs of women learners (Cuban & Hayes, 1996; Hayes & Flannery, 2000; Miller & Alexander, 2004; Young & Padilla, 1990). In recent years, educators have been developing innovative curriculum to address such issues as trauma and violence (e.g., Take on the Challenge), work-readiness (e.g. Ready for Work), or women's issues in general (Making Connection). New Directions-- Empowering Women through Literacy: Voices from Experience is the first comprehensive collection of writing from the field by everyday educators who experience the joys and challenges, creativity and barriers to acknowledge or integrate innovative solutions to support women's learning needs in adult basic education and literacy settings. Mirroring the power of community-based and grassroots organizations, this volume has had a remarkable history. It has emerged from five years of work by WE LEARN (Women Expanding Literacy Education Action Resource Network) to address the needs of literacy educators and students alike through the organization. The vibrant collective of the WE LEARN network provides consistent visibility for women’s literacy issues, creates connections among educators and activists, supports selfefficacy among learners, encourages new research relevant to women in ABE, and develops and distributes women-focused literacy materials and curriculum resources. It continues to be the only national U.S. organization directly addressing issues of adult women's literacy and the educational needs of women in ABE. We know you will enjoy this volume that provides an opportunity to hear from 47 contributors from around the world who reflect on their experiences with critical topics of adult literacy practices; how to empower women through literacy and current research based practice. From Belize to Australia, Brazil to Germany, and USA to Turkey, the voices of women engaged in empowerment are awaiting you through these pages. Literacy can change lives, how can we better reach those who desire this empowerment? Join us we explore the breadth of vision and knowledge captured within this groundbreaking volume. The Editors: Dr. Mev Miller and Dr. Kathleen P. King are co-editors of this volume within the Adult Education Series of Information Age Publishing. Mev Miller is the founder and director of WE LEARN, headquartered in Cranston, RI (www.litwomen.org). Kathy King is a professor of adult education at Fordham University’s Graduate School of Education in New York City. They and 45 other contributors join together in this volume to celebrate the unheralded capacity of literacy’s empowerment in women’s lives.

Book Description
This book is an edited collection of essays by fourteen multicultural women (including a few Anglo women) who are doing work that crosses the boundaries of ecological and social healing. The women are prominent academics, writers and leaders spanning Native American, Indigenous, Asian, African, Latina, Jewish and Multiracial backgrounds. The contributors express a myriad of ways that the relationship between the ecological and social have brought new understanding to their experiences and work in the world. Moreover by working with these edges of awareness, they are identifying new forms of teaching, leading, healing and positive change. Ecological and Social Healing is rooted in these ideas and speaks to an "edge awareness or consciousness." In essence this speaks to the power of integrating multiple and often conflicting views and the transformations that result. As women working across the boundaries of the ecological and social, we have powerful experiences that are creating new forms of healing. This book is rooted in academic theory as well as personal and professional experience, and highlights emerging models and insights. It will appeal to those working, teaching and learning in the fields of social justice, environmental issues, women's studies, spirituality, transformative/environmental/sustainability leadership, and interdisciplinary/intersectionality studies.

Book Description
Preservation of natural and cultural heritage is often said to be something that is done for the future, or on behalf of future generations, but the precise relationship of such practices to the future is rarely reflected upon. Heritage Futures draws on research undertaken over four years by an interdisciplinary, international team of 16 researchers and more than 25 partner organisations to explore the role of heritage and heritage-like practices in building future worlds. Engaging broad themes such as diversity, transformation, profusion and uncertainty, Heritage Futures aims to understand how a range of conservation and preservation practices across a number of countries assemble and resource different kinds of futures, and the possibilities that emerge from such collaborative research for alternative approaches to heritage in the Anthropocene. Case studies include the cryopreservation of endangered DNA in frozen zoos, nuclear waste management, seed biobanking, landscape rewilding, social history collecting, space messaging, endangered language documentation, built and natural heritage management, domestic keeping and discarding practices, and world heritage site management.

Book Description
Romand Coles here explores the writings of Augustine, Foucault, and Merleau-Ponty in order to fashion an ethos that emphasizes the value of dialogical relationships between the self and others. In his view, each of these thinkers has made significant contributions that must figure in any reconsideration of the relationship between the self, ethics, and power. Whereas Augustine saw depth as the dimension of freedom and truth, according to Coles's reading, Foucault regarded depth as "that dimension in which we rout out the other and constitute ourselves in light of hegemonic norms implanted deep within us." After drawing out those aspects of Foucault's thought which point toward a "dialogical artistic ethics," Coles explores Merleau-Ponty's philosophy of depth, arguing that it elucidates the "intercorporeality" of the world in a way that emphasizes the value of our dialogical relations with different others. In conclusion, he brings the three thinkers together to assess their rhetorical and philosophical similarities and differences, and to argue against the tendency to see all post-modern thought as nihilistic and incapable of developing an ethico-political stance. Coles's highly original work seeks to provide an alternative to the positions that have structured most recent debate in political philosophy. Thus, his book points up difficulties in both the individualist and the communitarian readings of politics and ethics, even as it seriously explores the ethical dimensions and possibilities of post-modernist thought. His attempt to develop an ethos based on a specific conception of selves and the world enables him to cast provocative light on the continuing dialogue between rationalists and relativists about the nature of both selves and our social and political institutions.
