For a graph G=(V,E), a double Roman dominating function is a function f:V→{0,1,2,3} having the property that if f(v)=0, then vertex v must have at least two neighbors assigned 2 under f or one ...neighbor with f(w)=3, and if f(v)=1, then vertex v must have at least one neighbor with f(w)≥2. The weight of a double Roman dominating function f is the sum f(V)=∑v∈Vf(v), and the minimum weight of a double Roman dominating function on G is the double Roman domination number of G. We initiate the study of double Roman domination and show its relationship to both domination and Roman domination. Finally, we present an upper bound on the double Roman domination number of a connected graph G in terms of the order of G and characterize the graphs attaining this bound.
This book explores the ways in which a range of recent American novelists have handled the genre of the 'coming-of-age' novel, or the Bildungsroman. Novels of this genre characteristically dramatise ...the vicissitudes of growing up and the trials and tribulations of young adulthood, often presented through depictions of immediate family relationships and other social structures.
Why have Americans expressed concern about immigration at some
times but not at others? In pursuit of an answer, this book
examines America's first nativist movement, which responded to the
rapid ...influx of 4.2 million immigrants between 1840 and 1860 and
culminated in the dramatic rise of the National American Party. As
previous studies have focused on the coasts, historians have not
yet completely explained why westerners joined the ranks of the
National American, or "Know Nothing," Party or why the nation's
bloodiest anti-immigrant riots erupted in western cities-namely
Chicago, Cincinnati, Louisville, and St. Louis. In focusing on the
antebellum West, Inventing America's First Immigration
Crisis illuminates the cultural, economic, and political
issues that originally motivated American nativism and explains how
it ultimately shaped the political relationship between church and
state. In six detailed chapters, Ritter explains how unprecedented
immigration from Europe and rapid westward expansion reignited
fears of Catholicism as a corrosive force. He presents new research
on the inner sanctums of the secretive Order of Know-Nothings and
provides original data on immigration, crime, and poverty in the
urban West. Ritter argues that the country's first bout of
political nativism actually renewed Americans' commitment to
church-state separation. Native-born Americans compelled Catholics
and immigrants, who might have otherwise shared an affinity for
monarchism, to accept American-style democracy. Catholics and
immigrants forced Americans to adopt a more inclusive definition of
religious freedom. This study offers valuable insight into the
history of nativism in U.S. politics and sheds light on present-day
concerns about immigration, particularly the role of anti-Islamic
appeals in recent elections.
Modern America owes the Roman Empire for more than gladiator movies and the architecture of the nation's Capitol. It can also thank the ancient republic for some helpful lessons in globalization. So ...argues economic historian Harold James in this masterful work of intellectual history.
The book addresses what James terms "the Roman dilemma"--the paradoxical notion that while global society depends on a system of rules for building peace and prosperity, this system inevitably leads to domestic clashes, international rivalry, and even wars. As it did in ancient Rome, James argues, a rule-based world order eventually subverts and destroys itself, creating the need for imperial action. The result is a continuous fluctuation between pacification and the breakdown of domestic order.
James summons this argument, first put forth more than two centuries ago in Adam Smith'sWealth of Nationsand Edward Gibbon'sDecline and Fall of the Roman Empire, to put current events into perspective. The world now finds itself staggering between a set of internationally negotiated trading rules and exchange--rate regimes, and the enforcement practiced by a sometimes-imperial America. These two forces--liberal international order and empire--will one day feed on each other to create a shakeup in global relations, James predicts. To reinforce his point, he invokes the familiarbon motonce applied to the British Empire:"When Britain could not rule the waves, it waived the rules."
Despite the pessimistic prognostications of Smith and Gibbon, who saw no way out of this dilemma, James ends his book on a less depressing note. He includes a chapter on one possible way in which the world could resolve the Roman Predicament--by opting for a global system based on values as opposed to rules.

During the early modern period, thousands of Jesuits across Europe wrote individual applications for appointments in the “Indies” directly to the superior general of the Society of Jesus in Rome. ...Known today as litterae indipetae (from Indias petere, that is, applying for the missions in the Eastern and Western territories), these letters encompassed the most personal desires, hopes, and dreams of young Jesuits who sought to become missionaries. This book is the first English monograph on litterae indipetae and studies their style and structure, the background of their authors and the reasons behind their choices, as well as the network surrounding this practice (natural and spiritual families, procurators, confrères). Its purpose is also to capture the experiences of these individuals since lost to history by studying thousands of indipetae, in this case written mainly by Italian Jesuits at the turn of the eighteenth century. It focuses especially on the petitions aimed at East Asia, and offers in-depth analysis of cases of Jesuits whose missionary zeal for China and Japan was fulfilled—or not.
Bringing together specialists in ancient history, archaeology and Roman law, this book provides new perspectives on long-distance trade in the Roman world. Recent archaeological work has shown that ...maritime trade across the Mediterranean intensified greatly at the same time as the Roman state was extending its power overseas. This book explores aspects of this development and its relationship with changes in the legal and institutional apparatus that supported maritime commerce. It analyses the socio-legal framework within which maritime trade was conducted, and in doing so presents a new understanding of the role played by legal and social institutions in the economy of the Roman world.
The public/private distinction is fundamental to modern theories of the family, religion and religious freedom, and state power, yet it has different salience, and is understood differently, from ...place to place and time to time. The volume examines the public/private distinction in the cultures and religions of the ancient Mediterranean, in the formative periods of Greece and Rome and the religions of Judaism, Christianity and Islam.
