新一輪經濟和政治危機，正在成形當一小部分機構獲得能夠操控一個國家政治和經濟的手段時，就會出現「寡頭難題」（或稱為「權力集中問題」）。如今，兩個二十世紀後期的機構──指數基金和私募股權基金──正在製造新一輪的權力集中問題。這兩種基金的規模如此龐大，對經濟的影響層面又如此之廣，使得它們擁有自己也未必想要的經濟與政治權力。它們因為手握大權，成為政治威嚇的目標。這兩種機構都展現出規模經濟，都經由控制企業而直接或間接地積極參與政治。先鋒集團（Vanguard）、道富集團（State Street）、富達集團（Fidelity）和貝萊德（BlackRock）這四大指數基金掌握著超過20%的S&P 500公司的投票權，這種權力集中度在美國是前所未有的。此外，私募股權基金的崛起，諸如阿波羅（Apollo）、黑石（Blackstone）、凱雷（Carlyle）和KKR這四大基金，已聚積了2.7兆美元的資產，它們正在侵蝕美國資本主義的合法性和責任，不是透過控制上市公司，而是透過完全接管它們，使其脫離公共討論和公眾監督。在過去的幾十年裡，這種無聲的聚積代表了美國經濟運作方式的巨大轉變，這是很少有人注意到、但所有人都應該關注的變化。哈佛大學法學教授約翰‧科茨在本書中分析並解答：有沒有可能在不損及兩種機構創造出來的經濟效益的狀況下，又能降低它們各自在經濟、政治和政策方面造成的風險？專業推薦——Jenny／JC財經觀點創辦人Mr. Market市場先生／財經作家王俊傑／國立中山大學政治經濟學系副教授林志潔／國立陽明交通大學特聘教授、金融消費評議中心前董事長（依姓名筆畫排序）「科茨主張，沒有責任的權力總是危險的。而他是對的。」──《紐約時報》 （New York Times）「資本主義由掌握資本的人決定。約翰‧科茨依據一生的經驗和研究，提出一個引人注目的觀點，認為美國資本主義在二十一世紀初由十二家不夠負責任的機構主導。他的開創性分析和建議值得所有關心我們經濟未來的人關注。」──勞倫斯‧桑默斯（Lawrence H. Summers），美國財政部前部長，哈佛大學甘迺迪學院摩薩瓦─拉赫馬尼商業與政府中心主任「從集中經濟權力中產生的政治危險是美國歷史中一個反覆出現的主題。科茨的書針對少數私營金融機構的影響提供了不可或缺的指導，也對我們如何應對集中金融權力提供了必要的答案。」──吳修銘（Tim
Former WWE head writer Brian Gewirtz brings readers behind the scenes for an unprecedented look at the chaotic, surreal, unbelievable backstage world of the WWE.With untold stories from a career spanning over 15 years and featuring the biggest names and controversial moments in wrestling history, THERE'S JUST ONE PROBLEM is an honest, unflinching look on how an introverted life-long fan unexpectedly became one the most powerful men in all of professional wrestling.For decades wrestling was shrouded in secrecy. It had larger than life personalities, bone crunching physicality and jaw-dropping theatrics but backstage it was an industry devoid of outsiders. Then in 1999, after working together on a special for MTV, Dwayne “The Rock” Johnson turned to 26-year old television writer Brian Gewirtz and asked “You ever consider writing for WWE?” That question, and its answer, would have a profound effect on both of their lives for years to come.THERE'S JUST ONE PROBLEM is a story about perseve
Twelve-year-old Emily wants to enjoy summer camp, with its competitions and pranks and just not think about the possibility that her parents may be breaking up--but the stress of keeping that problem
The striking theorems showcased in this book are among the most profound results of twentieth-century analysis. The authors' original approach combines rigorous mathematical proofs with commentary on the underlying ideas to provide a rich insight into these landmarks in mathematics. Results ranging from the proof of Littlewood's conjecture to the Banach–Tarski paradox have been selected for their mathematical beauty as well as educative value and historical role. Placing each theorem in historical perspective, the authors paint a coherent picture of modern analysis and its development, whilst maintaining mathematical rigour with the provision of complete proofs, alternative proofs, worked examples, and more than 150 exercises and solution hints. This edition extends the original French edition of 2009 with a new chapter on partitions, including the Hardy–Ramanujan theorem, and a significant expansion of the existing chapter on the Corona problem.

How do southerners feel about the ways in which the rest of the country regards them? In this volume, twelve observers of the modern South discuss its persistent image as a people and place at odds wi
Jack Boss takes a unique approach to analyzing Arnold Schoenberg's twelve-tone music, adapting the composer's notion of a 'musical idea' - problem, elaboration, solution - as a framework and focusing on the large-scale coherence of the whole piece. The book begins by defining 'musical idea' as a large, overarching process involving conflict between musical elements or situations, elaboration of that conflict, and resolution, and examines how such conflicts often involve symmetrical pitch and interval shapes that are obscured in some way. Containing close analytical readings of a large number of Schoenberg's key twelve-tone works, including Moses und Aron, the Suite for Piano Op. 25, the Fourth Quartet, and the String Trio, the study provides the reader with a clearer understanding of this still-controversial, challenging, but vitally important modernist composer.

In this study, Luba Freedman examines the revival of the twelve Olympian deities in the visual arts of sixteenth-century Italy. Renaissance representations of the Olympians as autonomous figures in paintings, sculpture and drawing were not easily integrated into a Christian society. While many patrons and artists venerated the ancient artworks for their artistic qualities, others, nourished by religious beliefs, felt compelled to adapt ancient representations to Christian subjects. These conflicting attitudes influenced the representation of deities intentionally made all'antica, often resulting in an interweaving of classical and non-classical elements that is alien to the original, ancient sources. This study, the first devoted to this problem, highlights how problematic it was during the Cinquecento to display and receive images of pagan gods, whether shaped by ancient or contemporary artists. It offers new insights into the uneven absorption of the classical heritage during the ear
By the time Sir Arthur Conan Doyle had completed the twelve stories for The Strand Magazine that are gathered together in The Adventures of Sherlock Holmes, he was already growing tired of his most famous creation, but the financial incentive to continue was too great. So began the second series of stories, known as The Memoirs; these introduced such notable characters as Holmes' indolent brother, Mycroft, and Holmes' most dangerous adversary, Professor James Moriarty, the 'Napoleon of Crime'. The collection included such stories as 'The Adventure of the Resident Patient' and 'The Adventure of the Greek Interpreter', which Doyle would list later as amongst his favourites. It was to Moriarty that was delegated the task of ending the career of the world's finest consulting detective in a final, fatal encounter at The Reichenbach Falls in Switzerland in the concluding tale, 'The Final Problem'.

Confessional and often hilarious, in Normal Sucks a neuro-diverse writer, advocate, and father offers a radical message of acceptance and empowerment.Jonathan Mooney blends anecdote, expertise, and memoir to present a new mode of thinking about how we live and learn. As a neuro-diverse kid diagnosed with dyslexia and ADHD who didn't learn to read until he was twelve, the realization that he wasn't the problem--the system and the concept of normal were--saved Mooney's life. Here, he explores the toll that our narrow conception of normal takes on kids and adults both. But, he argues, if we can reorient the ways in which we think about diversity and disability, we can start a revolution.Mooney has been inspiring audiences with his story for nearly two decades. Now he's ready to share what he's learned from parents, educators, researchers, and kids in a book that is both a survival guide and a call to action. Whip-smart and inspiring--and movingly framed as a letter to his own young sons--
The genius of Carl Friedrich Gauss (1777–1855) and the novelty of his work (published in Latin, German, and occasionally French) in areas as diverse as number theory, probability and astronomy were already widely acknowledged during his lifetime. But it took another three generations of mathematicians to reveal the true extent of his output as they studied Gauss' extensive unpublished papers and his voluminous correspondence. This posthumous twelve-volume collection of Gauss' complete works, published between 1863 and 1933, marks the culmination of their efforts and provides a fascinating account of one of the great scientific minds of the nineteenth century. Volume 1 reproduces the 1801 Disquisitiones arithmeticae, a masterpiece of mathematical rigour, in which Gauss drew together and greatly extended the number-theoretic knowledge of his time. The final chapter, on the criterion for the constructibility of a regular polygon, solved a problem that had been open since antiquity.
