Dieses Buch vermittelt die ethischen Grundprinzipien eines gerechten, verfassungskonformen Steuerrechts und die wesentlichen Reformvorschläge und -perspektiven des 20. und 21. Jahrhunderts für ein transparentes und effizientes Steuersystem in Deutschland. Bereits vor über 100 Jahren initiierte der Reichsfinanzminister Matthias Erzberger eine umfassende Reform der Finanzverfassung und des Steuersystems, um ¿Gerechtigkeit im gesamten Steuerwesen zu schaffen¿. Doch die Systematik dieser ehemals international hoch angesehenen deutschen Steuergesetze hat in der Geschichte der Bundesrepublik Deutschland kontinuierlich gelitten, da der Gesetzgeber fortlaufend einer Vielzahl politischer Erwägungen den Vorrang einräumte. Aktuell stellen Steuerrechtswissenschaftler jedoch die Steuergerechtigkeit auf Basis konsistenter Prinzipien in den Mittelpunkt ihrer Überlegungen, um den Inhalt und die Grenzen der staatlichen Rechte zu bestimmen. Die in diesem Buch dargestellten ethisch fundiertenRechtsprinzipien bilden daher eine gute Grundlage, um ein neues Steuersystem für Deutschland zu gestalten, das einfacher, sozialer, transparenter und gerechter ist.

In this groundbreaking work, two world-renowned scholars argue that ecological destruction and industrial catastrophes constitute a direct threat to everyday life, the maintenance of which has been made the particular responsibility of women. In both industrialized societies and the developing countries, the new wars the world is experiencing, violent ethnic chauvinisms and the malfunctioning of the economy also pose urgent questions for ecofeminists. Is there a relationship between patriarchal oppression and the destruction of nature in the name of profit and progress? How can women counter the violence inherent in these processes? Should they look to a link between the women's movement and other social movements?Maria Mies and Vandana Shiva offer a thought-provoking analysis of these and many other issues from a unique North-South perspective. They critique prevailing economic theories, conventional concepts of women's emancipation, the myth of 'catching up' development, the philosophical foundations of modern science and technology, and the omission of ethics when discussing so many questions, including advances in reproductive technology and biotechnology.In constructing their own ecofeminist epistemology and methodology, these two internationally respected feminist environmental activists look to the potential of movements advocating consumer liberation and subsistence production, sustainability and regeneration. They argue for an acceptance of limits and reciprocity and a rejection of exploitation, the endless commoditization of needs, and violence.

A gripping new investigation into the underbelly of digital technology, which reveals not only how costly the virtual world is, but how damaging it is to the environment.If digital technology were a country, it would be the third-highest consumer of electricity behind China and the United States.Every year, streaming technology generates as much greenhouse gas as Spain - close to 1 per cent of global emissions.One Google search uses as much electricity as a lightbulb left on for up to two minutes.It turns out that the 'dematerialised' digital world, essential for communicating, working, and consuming, is much more tangible than we would like to believe. Today, it absorbs 10 per cent of the world's electricity and represents nearly 4 per cent of the planet's carbon dioxide emissions. We are struggling to understand these impacts, as they are obscured to us in the mirage of 'the cloud'.The result of an investigation carried out over two years on four continents, The Dark Cloud reveals the anatomy of a technology that is virtual only in name. Under the guise of limiting the impact of humans on the planet, it is already asserting itself as one of the major environmental challenges of the twenty-first century.

Navigating institutions and donor requirements to successfully access international climate finance is challenging for many countries. Establishing national climate funds can be a way to meet these challenges, ensuring the targeted use of funds and strengthening ownership. This book examines the establishment of two national climate funds in Brazil, the Low Carbon Agriculture Programme and the Amazon Fund. Their establishment must be seen against the background of a drastic shift in Brazilian climate policy, enabled by discursive changes, during the administration of the Workers' Party 2003 - 2016. Dr. Ursula Flossmann-Kraus is a climate finance specialist and has led and implemented projects and programmes for GIZ and the Commonwealth Secretariat.

Have you ever relied on the kindness of strangers? What brings people together to find hope and solidarity? What do we owe each other as citizens and comrades?Questions of care, intimacy, education, meaningful work, and social engagement lie at the core of our ability to understand the world and its possibilities for human flourishing. In Lean on Me feminist thinker Lynne Segal goes in search of hope in her own life and in the world around her. She finds it entwined in our intimate commitments to each other and our shared collective endeavours. Segal calls this shared dependence ‘radical care’. In recounting from her own life the moments of motherhood, and of being on the front line of second-wave feminism, she draws upon lessons from more than half a century of engagement in Left feminist politics, with its underlying commitment to building a more egalitarian and nurturing world. The personal and the political combine in this rallying cry to transform radically how we approach education, motherhood, and our everyday vulnerabilities of disability, ageing and enhanced needs.Only by confronting head-on these different forms of interdependence and care can we change the way we think about the environment and learn to struggle – together – against impending climate catastrophe.

Investing in engineering documentation (Docs) means investing in community user experience. This book teaches readers how mastering the docs-as-code ecosystem empowers communities to understand better their favorite products and Open-Source (OSS) technologies better.Author Alejandra Quetzalli believes that ¿docs-as-ecosystem¿ represents a more comprehensive and collaborative approach to documentation development than ¿docsas- code¿ because it recognizes that documentation is more than just code. Docs involve technical writing, design, community feedback, community management, accessibility, SEO, UX, and today¿ even Artificial Intelligence tools! The word ecosystem promotes a paradigm where we treat documentation as a complex and dynamic system that must be managed and nurtured.In this book, yoüll acquire practical skills such as creating public style guides, incorporating responsive and accessible design, designing user flows and information architecture, retrieving user feedback, and setting up Docs analytics. Yoüll learn to identify the difference in work processes between maintaining Docs for a product versus an OSS technology. Yoüll discover the secrets to managing technical writers and OSS contributions, all while building a thriving Docs community. To end on a futuristic note, yoüll discover why technical writers who harness Artificial Intelligence (AI) tools (i.e., ChatGPT) need not fear a robot uprising anytime soon. What You'll LearnExamine accessibility and the user experienceUnderstand Information architecture Review docs-as-ecosystem processes Manage technical writersOversee OSS Docs contributions Retrieve and integrate user feedback Build Docs and Education communities Who This Book is ForDevelopers of all levels, VPs of Product/Engineering, Product Managers, and Designers,
