New times create new needs - and new needs require new solutions. The New Pioneers is a practical guide for capitalists and idealists on how to navigate in the new economic world order.

It is about the social megatrends that are shaping our lives in new ways and creating a new face of capitalism. And it is about the pioneers that are paving the way for the new business revolution: this century's generation of visionary leaders, social entrepreneurs and social intrapreneurs.

'Hardcore business people are realising that they can increase their profits by incorporating social responsibility into their business, and heartcore idealists are realising that the use of market methods helps them meet their social goals successfully,' argues Tania Ellis.

With a wide array of cases from all over the world Tania Ellis explains the key principles of sustainable business success. Read The New Pioneers to gain insight into the new rules that are paving the way for business unusual - for the benefit of humanity and the bottom line.

ENDORSEMENTS FOR THE NEW PIONEERS

'[Tania Ellis's] book shows the spectrum of thinking and concrete action around socially and ecologically responsible business that has emerged in the last decade. This spectrum is much wider than any label such as Corporate Social Responsibility, Corporate Global Citizenship, Social Investment, Social Entrepreneurship or Social Business would suggest, and her work in aggregating this information will go a long way to inspiring others to lead further into the future. It comprises exciting opportunities of engaging new actors and forging new partnerships to "improve the state of the world".'

Professor Klaus Schwab (from the foreword), Founder and Executive Chairman, World Economic Forum; Founder, Schwab Foundation for Social Entrepreneurship

"The New Pioneers needs to be not only read - but more importantly acted on - by all of us at the frontiers of building and giving life to the new economy. As we enter the Age of Sustainability, it will be the abundancy of our talents that will drive innovation which sees the opportunity in extreme resource scarcity. To harness these talents across the globe, embracing different cultures on the basis of shared equity, we need to know what works and who is doing what, framed by a challenge to current mindsets. The New Pioneers provides all that - and much more"

Tony Manwaring, Chief Executive, Tomorrow's Company

"The world is changing and the new pioneers are the ones changing it. If you want to make sense of what's happening--or even better, if you want to help make it happen--read this book. It's a handbook for the global revolution!"

Alan M. Webber, Co-founding Editor, Fast Company magazine and Author, Rules of Thumb: 52 Truths for Winning at Business Without Losing Your Self

"We are living through one of history's great transitions - from the Age of Greed to the Age of Responsibility - and Tania Ellis's "new pioneers" are at the leading edge of the revolution. This is a book that informs and inspires, reminding us that a better world is not only possible, but is already being created. It is an insightful window on a remarkable movement -- and a call to action for us all."

Dr Wayne Visser, Director of CSR International and author of The Age of Responsibility

"I welcome The New Pioneers, as a contribution to moving forward the vision of more ethical and sustainable businesses, reforming markets and growing "greener" economies worldwide. Tania Ellis has performed a great service and we hope this book is widely-read!"

Hazel Henderson, author of Ethical Markets: Growing the Green Economy (2006) and President, Ethical Markets Media (USA and Brazil)

"For 150 years we have directed companies on two false assumptions, viz. that planet earth had infinite resources and an infinite capacity to absorb waste. The consequence is an ecological crisis which has driven companies into a new economy - business as unusual and learning to make more with less. The New Pioneers illustrates that the stakeholder inclusive governance approach now prevails and everyone has a role to play to make the new face of capitalism work."

Mervyn King, Chairman of the Global Reporting Initiative

"Past explorers and pioneers found and exploited 'new worlds'. Humanity will need multiple planets this century to meet its growing agricultural, industrial and consumer needs, but we only have one. So we have to build a new world on the one planet we have. Tania Ellis shows how new breeds of social innovators and entrepreneurs are leading the charge."

John Elkington, Co-Founder and Executive Chairman of Volans, Co-Founder and Non-Executive Director of SustainAbility, and Co-author of The Power of Unreasonable People

"If you are joining the social entrepreneurship revolution, or seeking to apply its principles in a mainstream business setting, this insightful and incredibly well researched book sets out the rules of the road ahead."

John Grant, Author of Co-opportunity and The Green Marketing Manifesto

"Plan A is central to the future competitive success of Marks &amp; Spencer, and to our future relationship with customers and suppliers alike. It is a powerful example that 'sustainable development' is making its way into the core of business strategy. It is no longer a nice-to-have, but a need-to-have. The New Pioneers - packed with case studies and guided by the principles which inform them - shows how companies are leveraging their competitive advantage and building innovative business models by putting sustainability into the core of their thinking and practice"

Richard S. Gillies, Director, Plan A, CSR &amp; Sustainable Business, Marks &amp; Spencer

"Like James Cameroun with his movie Avatar is changing the film industry from two dimensions to three dimensions, Tania Ellis's new book shows the changing face of business from a one dimensional profit focus to capitalism in three dimensions. The New Pioneers takes the reader on a step-by-step journey through the evolution of business and its stakeholders providing new insights, lessons learned and roads to walk for creating a future where business globally will play an important part of creating a better world today and tomorrow."

Mads Kjaer, founder of MYC4

".........'The New Pioneers' is a very timely arrival that talks about developing future leaders and talent as businesses begin to recognize more and more that corporate sustainability is stretching the bandwidth of both current business models as well as their leadership profiles."

Anant G Nadkarni, Vice President - Group Corporate Sustainability, Tata

'In meticulous, convincing and heartening detail, Tania Ellis rolls out persuasive evidence that a "responsibility revolution" is well underway in the relationship between consumers and corporations. It is empowered by global communications networks the market revolutionaries of past generations - from Henry Ford to Ralph Nader - could never have conceived. It is inspired by indisputable proof - from climate change to the Great Recession - that we are indeed one world and that conscience is the best business model. Today, with governments having difficulty addressing some of the world's most perplexing problems, consumers, corporations and civil society must take the lead. As Ms Ellis documents so skillfully, that is precisely what they are doing.'

William Becker, Presidential Climate Action Project

Social Media for Trainers

In Fan the Flame, New York Times best-selling author and pastor Jim Cymbala looks at the pressing need for spiritual leadership by focusing our attention on Acts 20---Paul's farewell address to the Ephesian church. Along the way, Jim includes stories from his own experience at The Brooklyn Tabernacle, a church he has led for more than forty years.

Churches across the country are floundering and many pastors are deeply discouraged. They work hard and with great sincerity but their efforts don't seem to be helping their churches to flourish. Their congregations are split over political issues. Their faith is low. Finances are tight. Many leaders want to love their flocks, but find themselves in endless arguments with people they are trying to serve.The pressing need of our time, especially for leaders, is not to focus on transforming the culture, but on reviving the church. Yet sadly, when it comes to the work of ministry, few pastors turn to Scripture. Instead, they follow the latest church growth trends based on business models rather than the New Testament, and they become frustrated and disheartened when these fail.The first Christians had no money and no leverage. The Roman government opposed them at every turn. The Jewish establishment persecuted them. They had no buildings and no New Testament. Yet the church exploded, proving that the Gospel is built for the hardest of times.In Fan the Flame, New York Times best-selling author and pastor Jim Cymbala looks at the pressing need for spiritual leadership by focusing our attention on Acts 20--Paul's farewell address to the Ephesian church. He examines how Paul led the church--so that we can follow his lead. Along the way, Jim includes stories from his own experience at The Brooklyn Tabernacle, a church he has led for more than forty years. He offers ground-level, faith-driven, nitty-gritty, biblically-wise advice that will encourage, inspire, and equip leaders in the church, wherever God has planted them.When leaders begin to understand and practice true spiritual leadership, they will find that their lives are transformed and they discover fresh energy and peace as God leads the way in building his kingdom. Filled with practical insights on developing a practice of prayer and leading others into the presence of God, Fan the Flame will help you to become the kind of leader God can use to reignite revival in today's church.

This book examines why laws fail and provides strategies for making laws that work. Why do some laws fail? And how can we make laws that actually work? This helpful guide, written by a leading jurist, provides answers to these questions and gives practical strategies for law-making. It looks at a range of laws which have failed; the 'damp squibs' that achieve little or nothing in practice; laws that overshoot their policy goals; laws that produce nasty surprises; and laws that backfire, undermining the very goals they were intended to advance. It goes on to examine some of the reasons why such failures occur, drawing on insights from psychology and economics, including the work of Kahneman and others on how humans develop narratives about the ways in which the world works and make predictions about the future. It provides strategies to reduce the risk of failure of legislative projects, including adopting a more structured and systematic approach to analysing the likely effects of the legislation; ensuring we identify the limits of our knowledge and the uncertainties of our predictions; and framing laws in a way that enables us to adjust the way they operate as new information becomes available or circumstances change. Key themes include the importance of the institutions that administer the legislation, of default outcomes, and of the 'stickiness' of those defaults. The book concludes with helpful checklists of questions to ask and issues to consider, which will be of benefit to anyone involved in designing legislation.

Diplomarbeit aus dem Jahr 2008 im Fachbereich BWL - Wirtschaftspolitik, Note: 1,3, Frankfurt University of Applied Sciences, ehem. Fachhochschule Frankfurt am Main, Sprache: Deutsch, Abstract: Aufgabe der Abschlussprüfung ist die Erarbeitung und Dokumentation eines vertrauenswürdigen Urteils über die Richtigkeit der in den Abschlüssen enthaltenen Managementinformationen. Hierdurch soll das Vertrauen der Öffentlichkeit in die Verlässlichkeit von Jahresabschlussinformationen gewahrt werden. Jedoch ließen in der Vergangenheit zahlreiche Bilanzskandale verstärkt Zweifel an der Integrität des Prüferberufs und an deren Urteilsfähigkeit aufkommen.1 Wird das Vertrauen der Öffentlichkeit in die Verlässlichkeit der in den Unternehmensabschlüssen enthaltenen Informationen beeinträchtigt, so bedarf es besonderer Anstrengungen seitens des Gesetzgebers, um dieses wiederherzustellen. Auf die Bilanzskandale und die daraus folgenden Unternehmenszusammenbrüche (Enron und Worldcom2), reagierte der amerikanische Gesetzgeber mit der Verabschiedung des Sarbanes Oxley Act (SOX).3 Die wesentliche Gemeinsamkeit bei-der Skandale bildeten die zweifelhaften Bilanzierungspraktiken, die von den Abschlussprüfern nicht entdeckt oder gar verschwiegen wurden.4 Daher befasst sich das Gesetz zum einen mit der Selbstregulierung der Wirtschaftsprüfer und zum anderen mit der Corporate Governance5 von kapitalmarktorientierten Unternehmen.6 Das Gesetz „entfaltet exterritoriale Wirkung“7, da auch ausländische Prüfungsgesellschaften zur Einhaltung der Bestimmungen des SOX verpflichtet wer-den, sofern sie Leistungen für kapitalmarktorientierte Unternehmen erbringen, die bei der US-amerikanischen Börsenaufsicht Securities und Exchange Commission (SEC) registriert sind.   Die Bilanzskandale in den USA und der EU haben der EU-Kommission ebenfalls vor Augen geführt, wie wichtig die Abschlussprüfung für die Verlässlichkeit und die Glaubwürdigkeit des Jahresabschlusses von Unternehmen ist.

Als die Evangelien verfasst wurden, stand das frühchristliche Denken schon in Beziehung zu den antiken Erinnerungskulturen und den vielfältigen Traditionen hellenistischer Geschichtsschreibung. Dennoch ist bisher wenig darüber geschrieben worden, wie sich das frühchristliche Geschichtsbewusstsein literarisch entwickelt hat. In dieser Studie untersucht Eve-Marie Becker die verschiedenen Kontexte und Formen, in denen Geschichte in der hellenistischen Literaturtradition geschrieben und gedeutet wurde, und konzentriert sich dabei speziell auf die Zeit, in der die neutestamentlichen Schriften entstanden: von der Mitte des ersten bis zum frühen zweiten Jahrhundert. Becker weist auf Ansätze frühchristlichen
Geschichtsbewusstseins schon bei Paulus hin und beschreibt im Weiteren die konzeptionellen Ursprünge geschichtsschreibender Literatur von Markus zu Lukas. Die Studie zeigt, wie die früheste christliche Erzählliteratur das 'christliche' Denken über Geschichte formt und fortan prägt.
